getting at a UIButton with the tag property IPhone
I'm having a little trouble using the tag property to access a UIButton
UIButton *randomButton = [[UIButton buttonWithType:UIButtonTypeRoundedRect ]];
randomButton.frame = CGRectMake(205, 145, 90, 22); // size and position of button
[randomButton setTitle:@"Random" forState:UIControlStateNormal];
randomButton.backgroundColor = [UIColor clearColor];
randomButton.adjustsImag开发者_如何学PythoneWhenHighlighted = YES;
[randomButton addTarget:self action:@selector(getrandom:)
forControlEvents:UIControlEventTouchUpInside];
randomButton.reversesTitleShadowWhenHighlighted=YES;
randomButton.toggleButton
[self.view addSubview:randomButton];
randomButton.tag=333;
Then later on in code I try to get at the button in the following manner which gives me an error saying
Incompatible Objective-C types initializing 'struct UIView *', expected 'struct UIButton *'
UIButton *random = [self.view viewWithTag:333];
random.highlighted=NO;
Try:
UIButton *random = (UIButton *)[self.view viewWithTag:333];
Also, why are you assigning the tag after you have released the button?
