活动指示器只是带有图像序列动画的图像视图.要制作自己的活动指示器动画的每一帧的静态图片,并使用如下代码:

UIImageView *customActivityIndicator = [[UIImageView alloc] initWithFrame:CGRectMake(...)];

customActivityIndicator.animationImages = [NSArray arrayWithObjects:[UIImage imageNamed:@"frame1.png"],[UIImage imageNamed:@"frame2.png"],[etc...],[etc...],nil];
customActivityIndicator.animationDuration = 1.0; // in seconds
customActivityIndicator.animationRepeatCount = 0; // sets to loop

[customActivityIndicator startAnimating]; // starts animating
[customActivityIndicator stopAnimating]; //stops animating
