Why is my UIButton.tintColor not working?

Question

My build target is set for IOS5 which is where I understand UIButton.tintColor was introduced...

I have this in my viewDidLoad for the View Controller

Answer 1

Today, I also meet this problem. I use delegate to solve it.

[button addTarget:self action:@selector(buttonPress:) forControlEvents:UIControlEventTouchDown];
[button addTarget:self action:@selector(buttonPressReset:) forControlEvents:UIControlEventTouchUpInside | UIControlEventTouchUpOutside];

-(void)buttonPress:(id)sender{
UIButton* button = (UIButton*)sender;
[button setBackgroundColor:[UIColor greenColor]];
NSLog(@"buttonPressed");
}

-(void)buttonPressReset:(id)sender{
UIButton* button = (UIButton*)sender;
[button setBackgroundColor:[UIColor redColor]];
NSLog(@"buttonPressReset");
}
