To maintain these permissions, we will need to register the file as a 'Most Recently Used' file, and use the token returned from that operation for future access.In this video, I will show you how to save the state of a file picker.ReferencesXAML File Pickers -- http://msdn.microsoft.com/en-us/library/windows/apps/jj655411.aspx

The "viewDidLoad" method is invoked first. Inside it we should do any additional setup after loading the view, typically from a nib.There are other 4 commonly used methods that any iOS developer should know about:- (void)viewWillAppear:(BOOL)animated- (void)viewDidAppear:(BOOL)animated- (void)viewWillDisappear:(BOOL)animated- (void)viewDidDisappear:(BOOL)animated"viewWillAppear" is called when the view is about to made visible. Default does nothing."viewDidAppear" is called when the view has been fully transitioned onto the screen. Default does nothing."viewWillDisappear" is called when the view is dismissed, covered or otherwise hidden. Default does nothing."viewDidDisappear" is called after the view was dismissed, covered or otherwise hidden. Default does nothing.There are situations when we need some specific things to be done, for example to save some data if the user quits the app, and these and some other ones are the places where she to insert that logic in our projects.

For more videos on technology, visit our website at http://www.techytube.com.By mzmuda@techytube, for more from this author visit: http://www.techytube.com/author/mzmudaData binding is an essential concept to software development, and one that is luckily made near-trivial by Visual Studio.In a one-way binding, data is populated in one direction, to the end UI control. In this system, changing a value in the control does not reflect in the data source.In a two-way binding scenario, data can flow back from the control to the data source. This is useful for an 'edit' role, versus a 'label' role which would more appropriately make use of one-way binding.Data binding was made popular in WinForms (.NET 2.0), and Visual Studio 2012 makes it intuitive. Through multiple methods, such as Binding.Source and DataContext switching, a control can be bound to a source in just a few clicks.In this video, I will show you how to bind a TextBlock to the DisplayName property in a file chosen from a FilePicker.ReferencesXAML File Pickers - http://msdn.microsoft.com/en-us/library/windows/apps/jj655411.aspx
How to create view controllers programmatically in iOS techytube 2012-12-10 | Subscribe to our channel here for notifications on new video trainings. For more videos on technology, visit our website at http://www.techytube.com.By pavel@techytube, for more from this author visit: http://www.techytube.com/author/pavelThe UINavigationController class implements a specialized view controller that manages the navigation of hierarchical content. This class is not intended for subclassing. Instead, you use instances of it as-is in situations where you want your application's user interface to reflect the hierarchical nature of your content. This navigation interface makes it possible to present your data efficiently and also makes it easier for the user to navigate that content.To create a navigation controller programmatically, you have to write the following code:UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:self.viewController];Usually that is done in the "AppDelegate.m" file, but it can be done in any file you need.If you do that in the "AppDelegate.m" file than you should replace the line:self.window.rootViewController = self.viewController;with the following line:self.window.rootViewController = navController;and it is perfectly ok because UINavigationController is a subclass of UIViewController.If you run the program, you may notice a blue navigation bar appears on the top. You can customise that if you want, or you can hide it using any of the 2 lines below:navController.navigationBarHidden = YES;navController.navigationBar.hidden = YES;To set a title in the NavBar, you should write in the "viewDidLoad" method of the ViewController class that is currently displayed by the Navigator object, any of the 2 lines below:self.navigationItem.title = @"Title";self.title = @"Title";

For more videos on technology, visit our website at http://www.techytube.com.By pavel@techytube, for more from this author visit: http://www.techytube.com/author/pavelThe UIPickerView class implements objects, called picker views, that use a spinning-wheel or slot-machine metaphor to show one or more sets of values. Users select values by rotating the wheels so that the desired row of values aligns with a selection indicator.The UIDatePicker class uses a custom subclass of UIPickerView to display dates and times. To see an example, tap the add ("+") button in the the Alarm pane of the Clock application.The user interface provided by a picker view consists of components and rows. A component is a wheel, which has a series of items (rows) at indexed locations on the wheel. Each component also has an indexed location (left to right) in a picker view. Each row on a component has content, which is either a string or a view object such as a label (UILabel) or an image (UIImageView).For more information, you can check the Apple's online Documentation at:http://developer.apple.com/library/ios/#documentation/uikit/reference/UIPickerView_Class/Reference/UIPickerView.html

To do that, we have 4 options:UIDatePickerModeTimeUIDatePickerModeDateUIDatePickerModeDateAndTimeUIDatePickerModeCountDownTimer, which represent the values of an Enum type in the iOS SDK. Usually we do that in Xcode Interface Builder, if the date-pickers are created visually as well.When we interact with the UIDatePicker objects, we can call different event methods. The most common (which also comes as the default option when making the IBAction connection) is:"- (IBAction)datePickerValueChanged:(id)sender". If we want to get the value of the selected date and/or time from out picker in one of these methods, we can refer to the IBOutlet object or property if we have one, or we can change the parameter type from "id" to "UIDatePicker *", and then use the sender parameter-object (which is the actual UIDatePicker object).

The data source provides the table view object with the information it needs to construct and modify a table view.As a representative of the data model, the data source supplies minimal information about the table view's appearance. The table-view object's delegate—an object adopting the UITableViewDelegate protocol—provides that information.In the last video we've discussed about the required methods of the UITableViewDelegate protocol. There are also a couple of optional methods. For example in case of Grouped-Style table-views, we have sections, and each section may have a header and a footer.To specify how many sections a table view should have, we implement the following method:- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{ return 2; // 2 should be replaced with the number of sections we need}To specify the title of each section in a table view, we implement the following method:- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section{ NSString *titleOfSection; switch (section) { case 0: titleOfSection = @"First Section"; break; case 1: titleOfSection = @"Second Section"; // ... and so on, depending how many sections we must have default: titleOfSection = @"No Title"; break; } return titleOfSection;}For more, please visit Apple's online documentation at:http://developer.apple.com/library/ios/#documentation/uikit/reference/UITableViewDataSource_Protocol/Reference/Reference.html

The table-view object's delegate—an object adopting the UITableViewDelegate protocol—provides that information.The two required methods of the protocol provide the cells to be displayed by the table-view as well as inform the UITableView, and they should look as below:- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{ return 3;}- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{ static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]; } return cell;}We can also set the cell's properties, for example:cell.textLabel.text = [NSString stringWithFormat:@"Cell %d", indexPath.row];Many methods take NSIndexPath objects as parameters. UITableView declares a category on NSIndexPath that enables you to get the represented row index (row property) and section index (section property), and to construct an index path from a given row index and section index (indexPathForRow:inSection: class method). (The first index in each index path identifies the section and the next identifies the row.)For more, please visit Apple's online documentation at:http://developer.apple.com/library/ios/#documentation/uikit/reference/UITableViewDataSource_Protocol/Reference/Reference.html

Optional methods of the protocol allow the delegate to manage selections, configure section headings and footers, help to delete and reorder cells, and perform other actions.Many methods of UITableViewDelegate take NSIndexPath objects as parameters and return values. UITableView declares a category on NSIndexPath that enables you to get the represented row index (row property) and section index (section property), and to construct an index path from a given row index and section index (indexPathForRow:inSection: method). Because rows are located within their sections, you usually must evaluate the section index number before you can identify the row by its index number.One very important method is:- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPathand it used in Master-Detail applications, where we have a Main/Master view which contains a basic table with general information about the items that we want to display, and when we click on any of the items, it takes us to a Detailed view, which contains all the info about the selected item.For more, please visit Apple's online documnation at:http://developer.apple.com/library/ios/#documentation/uikit/reference/UITableViewDelegate_Protocol/Reference/Reference.html
How to create a custom cell programmatically in iOS techytube 2012-11-19 | Subscribe to our channel here for notifications on new video trainings. For more videos on technology, visit our website at http://www.techytube.com.By pavel@techytube, for more from this author visit: http://www.techytube.com/author/pavelA cell in a UITableView is an object of UITableViewCell class, and can have one of four styles, which are:UITableViewCellStyleDefault, UITableViewCellStyleSubtitle, UITableViewCellStyleValue1, and UITableViewCellStyleValue2, and you can use those according to your app's specifications, or you can create your custom cells.In this video tutorial we will create a custom cell programmatically. For that we have to do most of our work in the "tableView:cellForRowAtIndexPath:" method. First we need a dataSource to populate the cell with info, so declare a private property for that, in the VieController.m file, just after the #import statement:@interface ViewController ()@property (nonatomic, retain) NSMutableArray *dataSource;@endThen, in the viewDidLoad method allocate and initialise that:self.dataSource = [NSMutableArray array]; [self.dataSource addObject:[NSArray arrayWithObjects:@"20", @"JUN", @"7:00PM", @"Toyota Center", @"Houston, TX", @"FROM", @"$200", nil]];[self.dataSource addObject:[NSArray arrayWithObjects:@"6", @"JUL", @"8PM", @"Frank Erwin Center", @"Austin, TX", @"FROM", @"$350", nil]];In the "tableView:numberOfRowsInSection:" method return self.dataSource.count.In the "tableView:cellForRowAtIndexPath:" method write:// Each subview in the cell will be identified by a unique tagstatic NSUInteger const kDayLabelTag = 2;static NSUInteger const kMonthLabelTag = 3;// ... and so on static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];UILabel *dayLabel;UILabel *monthLabel;// ... and so onif (cell == nil){ cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]; cell.selectionStyle = UITableViewCellSelectionStyleNone; // Define the frames for each component of the Cell CGRect dayFrame = CGRectMake(5, 7, 64, 30); CGRect monthFrame = CGRectMake(5, 35, 64, 16); // ... and so on // Adjust all the controls correspondingly dayLabel = [[UILabel alloc] initWithFrame:dayFrame]; dayLabel.tag = kDayLabelTag; dayLabel.font = [UIFont boldSystemFontOfSize:30.0f]; dayLabel.backgroundColor = [UIColor clearColor]; dayLabel.textColor = [UIColor darkGrayColor]; dayLabel.textAlignment = NSTextAlignmentCenter; monthLabel = [[UILabel alloc] initWithFrame:monthFrame]; monthLabel.tag = kMonthLabelTag; monthLabel.font = [UIFont boldSystemFontOfSize:16.0f]; monthLabel.backgroundColor = [UIColor clearColor]; monthLabel.textColor = [UIColor colorWithRed:0.0f/255.0f green:140.0f/255.0f blue:220.0f/255.0f alpha:1.0f]; monthLabel.textAlignment = NSTextAlignmentCenter; // ... and so on // Add all created components to the new Cell [cell.contentView addSubview:dayLabel]; [cell.contentView addSubview:monthLabel]; // ... and so on }else{ // A reusable cell was available, so we just need to get // a reference to the subviews using their tags dayLabel = (UILabel *) [cell.contentView viewWithTag:kDayLabelTag]; monthLabel = (UILabel *) [cell.contentView viewWithTag:kMonthLabelTag];} NSArray *cellInfoArray = [self.dataSource objectAtIndex:indexPath.row]; dayLabel.text = [cellInfoArray objectAtIndex:0];monthLabel.text = [cellInfoArray objectAtIndex:1]; return cell;

We can also have an image on the left.For the right side, we can specify different accessory types, which are:UITableViewCellAccessoryNone, UITableViewCellAccessoryDisclosureIndicator, UITableViewCellAccessoryDetailDisclosureButton, and UITableViewCellAccessoryCheckmark. Each accessory type has its own meaning, and you have to check that in the Human Interface Guidelines provided by Apple. In case you use them for different meaning your app may get rejected.For more, please visit Apple's online documentation at:http://developer.apple.com/library/ios/#documentation/uikit/reference/UITableViewCell_Class/Reference/Reference.html

Luckily, Visual Studio allows us to integrate both approaches.In this video, I will go over static and fluid layouts, and the tools available in the Visual Studio designer.ReferencesXAML Navigation, Layout, Views -- http://msdn.microsoft.com/en-us/library/windows/apps/jj215600.aspx

For more videos on technology, visit our website at http://www.techytube.com.By techytube@techytube, for more from this author visit: http://www.techytube.com/author/techytubeWindows 8 Store apps can be distributed to the general public through the Windows Store. For Line of Business applications that you may be developing in-house, an alternative distribution method exists. This requires a few steps:1. Create an APPX package by using the Store menu in Visual Studio. 2. You then have to Validate the app. This will be presented to you when you finish creating the APPX package. 3. Once validation is passed, Visual Studio will create a PowerShell script that can be used to do the App installation. For end-user systems to allow this installation to take place a few things are required. They need to be running the Enterprise version of the Windows 8 operating system and a Group Policy setting must be in place. Computer Configuration\Administrative Templates\Windows Components\App Package DeploymentThe setting that you need to enable here is:Allow all trusted apps to install settingDoing the above or setting the below registry key on all systems that will receive the app is:HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\Appx\AllowAllTrustedApps = 1Once these are in place, the installation should take place without any issues.Source:http://technet.microsoft.com/en-us/library/hh852635.aspx
