Adding Objects To A View

Declare The Inputs And Output in #ViewController.h

Declare the objects you will output to (control from code) and methods for the objects providing input. Examples: (more…)

You may want to make a reduced size view for say an input box of some sort or a view that will be used at the same size for both iPhone and iPad devices. (more…)

Create Simple Single View For An Application

Create the application

Create view file

(more…)

A great way of placing a new view over the top of a TabBarController etc which uses the whole screen (except for the status bar is there is one) so it looks as though the tab bar etc has gone. (more…)

The following superclass methods may be added to a #ViewController.m file

//*******************************
//*******************************
//********** LOAD VIEW **********
//*******************************
//*******************************
//View being loaded (happens only when view is initially loaded or reloaded in memory)
- (void)loadView
{
    [super loadView];
}

To Show A View Controller Modally

        #ViewController_iPhone *vc1 = [[#ViewController_iPhone alloc] init];
        [self presentModalViewController:vc1 animated:YES];
        //[ptabBarController presentModalViewController:vc1 animated:YES];   //An alternative
	[vc1 release];

An Example Using A Class

In #ViewController.h that you want to pass data to

#import

Don’t want to use UINavigationController or UITabBarController?  Then you have a problem as Apple doesn’t provide the means to control an apps views programatically very easily, for instance using code like this: (more…)

In the same way that autorelease doesn’t occur until all of the current events and functions have been completed for your application, although the window and it’s object may be marked to be re-drawn it will not occur until the application returns to the background run loop.  At this point the OS checks to see if anything need’s to be re-drawn.

Rename the .h, .m and .xib files

Update the name in the following places:

In #ViewController.h update @interface

Default Rotation

In the applicaitons Info.plist add the row: (more…)

Create Sideways Scrolling View Of Multiple Pages

This could be for a single page ap or as one of the views within say a UITabBarController
(more…)

Status Bar Size

20 pixels

Interface Builder Status Bar Setting

The “Simulated Metrics” don’t actually alter the status bar etc, it just simulates the size and colour of the status bar so that you can layout your views without having to shift everything down by 20 pixels. (more…)

UINavigationController provides a dynamic stack of views created at run time with a navigation bar at the top.  For many applications this is used to provide all of the views the user sees. (more…)

Applications use tab bar controllers to manage multiple distinct interfaces, each of which consists of any number of custom views and view controllers. For many applications the UITabBarController is used to provide all of the views the user sees. (more…)

Referencing A View In A .xib

In #ViewController.h

@interface SomeViewController : UIViewController
{
	UIView *MyView;
{
@property (nonatomic, retain) IBOutlet UIView *MyView;
