Question

我有一个ViewController有两个segues，我希望segue在从URL获取数据后呈现viewcontroller。所以我在Xcode 6方法中保留了update_attributes。

但我只能显示第一个viewcontroller。

我希望两个segues都正常工作。

before_save

如果你这样做，我相信你应该得到你需要的结果。

为按钮设置IBOutlets button1和button2，为按钮设置IBAction方法，并将其selected属性设置为YES。

- (IBAction)button1Clicked:(id)sender
{
    button1.selected = YES;
    if (button2.selected)
    {
        // This is done so that both buttons do not appear as clicked at the same time
        button2.selected = NO;
    }
}

- (IBAction)button2Clicked:(id)sender
{
    button2.selected = YES;
    if (button1.selected)
    {
        // This is done so that both buttons do not appear as clicked at the same time
        button1.selected = NO;
    }
}

完成此操作后，在您的connectionDidFinishLoading方法中执行此检查。

- (void)connectionDidFinishLoading:(NSURLConnection *)connection {

    NSString *teststr=[[NSString alloc]  initWithData:responseData encoding:NSUTF8StringEncoding];

    NSString *str1234 = [teststr stringByTrimmingCharactersInSet:[NSCharacterSet newlineCharacterSet]];
    NSLog(@"Response is %@ %lul",str1234,(unsigned long)
      [str1234 length]);


    [alert dismissWithClickedButtonIndex:0 animated:YES];

    if (button1.selected)
    {
        [self performSegueWithIdentifier:@"good" sender:self];
    }
    else if (button2.selected)
    {
        [self performSegueWithIdentifier:@"callback" sender:self];
    }
}

希望它有所帮助。
