]半透明的UIView作进度提示，或者说是半透明遮盖。附源码

看到这里有过讨论： http://www.cocoachina.com/bbs/read.php?tid-3679.html

正好也需要一个这样的界面，就写了一下。
没有使用UIAlertView是因为我不知道如何用代码使其消失（除非release，但我还想重复利用呢），而且也不知道如何让alert的边框隐藏掉……

以下是代码，用完后记得release

+(UIView *)waitingView { CGRect frame = CGRectMake(90, 190, 32, 32); UIActivityIndicatorView* progressInd = [[UIActivityIndicatorView alloc] initWithFrame:frame]; [progressInd startAnimating]; progressInd.activityIndicatorViewStyle = UIActivityIndicatorViewStyleWhiteLarge; frame = CGRectMake(130, 193, 140, 30); UILabel *waitingLable = [[UILabel alloc] initWithFrame:frame]; waitingLable.text = @ "Processing..." ; waitingLable.textColor = [UIColor whiteColor]; waitingLable.font = [UIFont systemFontOfSize:20];; waitingLable.backgroundColor = [UIColor clearColor]; frame = [[UIScreen mainScreen] applicationFrame]; UIView *theView = [[UIView alloc] initWithFrame:frame]; theView.backgroundColor = [UIColor blackColor]; theView.alpha = 0.7; [theView addSubview:progressInd]; [theView addSubview:waitingLable]; [progressInd release]; [waitingLable release]; return theView; }
