UIAlertView背景問題？

Question

I在我的課堂中使用Uialertview。

這裏是我的代碼

UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:nil message:@"message" delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil]; 
[alertView show]; 

但問題是，當我按ok鍵，報警皮，但黑色的背景仍然存在。

有沒有人有這個答案？

Answer 1

在你的代碼[[UIAlertView alloc]initWithTitle:nil @"message"應該initWithTitle:@"message"

諸如此類，

UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Your Title" message:@"Your Message Body !!" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil]; 
[alert show]; 

Answer 2

試試這個。

UIAlertView * alertView = [[[UIAlertView alloc] initWithTitle:@"" message:@"message" delegate:nil cancelButtonTitle:@"Okay" otherButtonTitles:nil, nil] autorelease]; 
[alertView show]; 

Answer 3

嘗試，

UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:@"" message:@"message" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil, nil]; 
[alertView show];
