我儘量模擬內存不足的情況，它仍然是WORKSFORME。你有什麼想法嗎？

Answer 1

-(void)addAlertView 
{ 
    UIAlertView *alertView = [[UIAlertView alloc]initWithTitle: 
    @"Title" message:@"This is a test alert" delegate:self 
    cancelButtonTitle:@"Cancel" otherButtonTitles:@"Ok", nil]; 

    [alertView show]; 

} 

希望這將有助於ü..根據烏拉圭回合

組消息和按鈕需要

，如果它不能正常工作，然後從模擬器&刪除烏爾應用他們跑

Answer 2

我得到了相同的崩潰日誌，並且主要在運行iOS 7.0.4的設備上找到該日誌。 iOS 8.3之前的版本也有問題。

審查代碼後，我發現，使用AlertView類沒有聲明UIAlterViewDelegate協議。 OC Runtime可以確保委託方法正常運行，但我認爲iOS中有一些未知的邏輯。

我修正錯誤，崩潰日誌不見了....

後，我認爲這是錯誤的iOS已經在iOS 8.3版本
