Question

当我在UIAlertView的点击事件中弹出到根视图控制器时，我的应用程序崩溃。

我的代码如下：

- (void)alertView:(UIAlertView *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
    if (buttonIndex == 0 && ([errorCodeNew  isEqualToString:@"IPH_I_LGN_002"])){

     [self.navigationController popToRootViewControllerAnimated:YES];

    AppDelegate *appDelegate =  (AppDelegate*)[[UIApplication sharedApplication] delegate];
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    [defaults setObject:@"3" forKey:@"CurrentSize"];

    NSMutableArray *nsmarrJpName;
    DatabaseLogic *logic = [[DatabaseLogic alloc] init];
    appDelegate.anket_id = [logic getAnketID];

    nsmarrJpName = [[NSMutableArray alloc]initWithArray:[logic getDetailScreenItems:[logic getAnketID]] copyItems:YES];

    for (int i = 0;  i < [nsmarrJpName count]; i++) {
        NSString *strKey = [nsmarrJpName objectAtIndex:i];
        [defaults setObject: [NSNumber numberWithBool:YES] forKey:strKey];
        NSLog(@"key : %@", strKey);
    }

    [nsmarrJpName removeAllObjects];
    [nsmarrJpName release];

    appDelegate.strUserFlg = [logic getUserType];

    [logic release]; logic = nil;

    //start download process
    [[NSNotificationCenter defaultCenter] postNotificationName:LOGIN_COMPLETE_NOTIFICATION object:self userInfo:nil];
    }else{
        NSLog(@"cancel");
    }
}

我尝试用clickedButtonAtIndex方法替换didDismissWithButtonIndex。但我没有得到任何结果。

感谢。

尝试将[self.navigationController popToRootViewControllerAnimated：YES]移动到函数的底部（即在所有其他代码运行之后）。
