自定义加载指示器(微调)
答
这可以使用UIImageView来完成(如果你喜欢,你可以创建一个自定义的UIView子类)。基本代码是这样的:
UIImageView* animatedImageView = [[UIImageView alloc] initWithFrame:self.view.frame];
animatedImageView.animationImages = [NSArray arrayWithObjects:
[UIImage imageNamed:@"spinner-01.png"],
[UIImage imageNamed:@"spinner-02.png"],
[UIImage imageNamed:@"spinner-03.png"],
[UIImage imageNamed:@"spinner-04.png"],
nil];
animatedImageView.animationDuration = 1.0;
animatedImageView.animationRepeatCount = 0;
[animatedImageView startAnimating];
