Programmatically layout iPhone UIView?

I am using the iPhone toolchain on Linux and so I have no Interface Builder. So how could I layout my view in my ViewController subclass? For example, I want a UITextView in the middle of the screen? Should I do this in the loadView or viewDidLoad. Do I also have to set the view for the ViewController subclass to itself?

Solution

  • It is not an easy job to layout all the view using code. Here are some code:

    UITextView *textView = [[UITextView alloc] initWithFrame:CGRectMake (100, 100, 100, 100)];
[self.view addSubview:textView];

    The frame is the place (the first and second argument is x and y coordinator) and the size (the third and fourth argument is width and height of the text view).

    Using this way, you can add any view into your class. Some of the view is built in and you don't have to draw yourself, some of them is not, and you need to subclass UIView and override drawRect.

    You should do this in viewDidLoad when your main view controller is finished loading
