我使用一个Uialertview在我的类。
我的代码
UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:nil message:@"message" delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil];
[alertView show];
但是问题是当我按下ok按钮时,警报隐藏了,但是黑色背景仍然在那里。
有人知道这个问题的答案吗?
试试这个
UIAlertView * alertView = [[[UIAlertView alloc] initWithTitle:@"" message:@"message" delegate:nil cancelButtonTitle:@"Okay" otherButtonTitles:nil, nil] autorelease];
[alertView show];
在你的代码中[[UIAlertView alloc]initWithTitle:nil @"message"
应该 initWithTitle:@"message"
这样的喜欢,
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Your Title" message:@"Your Message Body !!" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
[alert show];
试试,
UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:@"" message:@"message" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
[alertView show];
