[英]How to change background color in iPhone app
I tried this code in the view controller, but it didn't work. 我在视图控制器中尝试了此代码,但是没有用。 Why is that?
这是为什么?
- (void)viewDidLoad {
[self setBackgroundColor:[UIColor colorWithRed:1.0 green:1.0 blue:1.0 alpha:1.0]];
[super viewDidLoad];
}
您应该将背景颜色设置为view ,而不是其控制器:
[self.view setBackgroundColor:[UIColor colorWithRed:1.0 green:1.0 blue:1.0 alpha:1.0]];
