我正在使用AlertController for iOS 8及更高版本。
編輯:用於顯示警報
示例代碼:
if (NSClassFromString(@"UIAlertController"))
{
UIAlertController *alert = [UIAlertController alertControllerWithTitle:title
message:msg
preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction* defaultAction = [UIAlertAction actionWithTitle:@"OK"
style:UIAlertActionStyleDefault
handler:nil];
[alert addAction:defaultAction];
//other UIAlertAction here......
[self presentViewController:alert animated:YES completion:nil];
}
else
{
[[[UIAlertView alloc]initWithTitle:title
message:msg
delegate:nil
cancelButtonTitle:@"OK"
otherButtonTitles:nil] show];
}
中的appDelegate也使用(通過獲取電流控制器和控制器上呈現警報)也可以是原因要點..?
你能在這裏粘貼你的代碼嗎? – Ricky 2014-10-07 06:02:41
我在應用程序中的許多地方使用警報。 – Pushparaj 2014-10-07 06:04:07
,但您可以使用斷點來查找代碼中應用程序崩潰的行。因此,我們很容易就可以幫助您。 – Ricky 2014-10-07 06:10:01
