Question

How do I create a simple button without using the Interface builder?

Answer 1

You would need to declare a UIButton like this:
UIButton *newButton = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 80, 40)];
[newButton setTitle:#"Some Button" forState:UIControlStateNormal];
You would then add the button to a view -
[self.view addSubview: newButton]; // (could be another view other then self.view)
And finally, if you want some action to occur when pressing that button, you would add:
[newButton addTarget:self action:#selector(doSomething)
forControlEvents:UIControlEventTouchUpInside];
and of course declare that function:
- (void) doSomething
{
NSLog(#"Button pressed");
}
And of course don't forget to release the button.

Try with below
UIButton *playButton = [[UIButton buttonWithType:UIButtonTypeRoundedRect];
playButton.frame = CGRectMake(110.0, 360.0, 100.0, 30.0);
[playButton setTitle:#"Play" forState:UIControlStateNormal];
playButton.backgroundColor = [UIColor clearColor];
[playButton setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal ];
UIImage *buttonImageNormal = [UIImage imageNamed:#"blueButton.png"];
UIImage *strechableButtonImageNormal = [buttonImageNormal stretchableImageWithLeftCapWidth:12 topCapHeight:0];
[playButton setBackgroundImage:strechableButtonImageNormal forState:UIControlStateNormal];
UIImage *buttonImagePressed = [UIImage imageNamed:#"whiteButton.png"];
UIImage *strechableButtonImagePressed = [buttonImagePressed stretchableImageWithLeftCapWidth:12 topCapHeight:0];
[playButton setBackgroundImage:strechableButtonImagePressed forState:UIControlStateHighlighted];
[playButton addTarget:self action:#selector(playAction:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:playButton];
