Question

如何加载UIActivityIndicatorView登录页面？就像facebook iPhone App一样.

Answer 1

你的问题不明确.但这是添加活动指标的方法.

UIActivityIndicatorView *activity = [[UIActivityIndicatorView alloc]initWithFrame:CGRectMake(225, 115, 30, 30)];
[activity setBackgroundColor:[UIColor clearColor]];
[activity setActivityIndicatorViewStyle:UIActivityIndicatorViewStyleGray];
[self.view addSubview:activity];
[activity release];

开始动画活动

[activity startAnimating];

停止动画活动

[activity stopAnimating];
