Depends what kind of button, you can also combine it with foreground and background images.
But a simple button you create programmatically:
Code:
UIButton *oneButton = [UIButton buttonWithType:UIButtonTypeRoundedRect]; // autoreleased
then you set the text:
Code:
[oneButton setTitle:@"Text" forState:UIControlStateNormal];
finally you need to add the button to the a view so that it get's displayed and retained.
Code:
[anyView addSubview:oneButton];
ah and you might want to set the button's dimensions. You can do this before or after the addSubview:
Code:
oneButton.frame = CGRectMake(x, y, w, h);
the buttonWithType class methods makes a autoreleased instance, the addSubview increases retain count to two. Then the autorelease pool draining reduces it to one.
when you finally call
Code:
[oneButton removeFromSuperview];
it disappears both from the screen as well as memory because this decreases the retainCount to 0 = dealloc.
