答

您可以添加标签和activityindicator作为警报视图的子视图。你必须做这样的事情

you can add a label and activityindicator as subviews of your alert view. you have to do some thing like this

myAlertView = [[UIAlertView alloc] initWithTitle:@"Loading" message:@"\n\n"
                                        delegate:self
                               cancelButtonTitle:@""
                               otherButtonTitles:@"OK", nil];  

UIActivityIndicatorView *loading = [[UIActivityIndicatorView alloc]
                initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray];   
loading.frame=CGRectMake(150, 150, 16, 16);
[myAlertView addSubview:loading];
[myAlertView show];

..在这种情况下更好地使用UIActionSheet ...
