可以檢測按鈕發件人是否來自Touch Up Inside和Touch Up Outside？

Question

我有一個按鈕，我希望它的Touch Up Inside和Touch Up Outside動作都采用相同的方法。 然后我想要方法來解決發生的事件，如下所示：

- (IBAction)buttonMethod:(UIButton *)sender forEvent:(UIEvent *)event {
if (event == UIControlEventTouchUpInside)
    NSLog(@"Touch up inside!");

if (event == UIControlEventTouchUpOutside)
    NSLog(@"Touch up outside!");   
}
}

這似乎不起作用，因為觸摸事件似乎從UIControl繼承，UIControl與UIEvent不在同一個Universe中。 有沒有辦法告訴我的方法哪個動作導致調用該方法？

將它拆分為兩種方法，如果由於某種原因你只想要一個邏輯傳遞消息。

- (IBAction)buttonMethod:(UIButton *)sender forEvent:(UIEvent *)event controlEvent:(UIControlEvents)event {
    if (event == UIControlEventTouchUpInside)
        NSLog(@"Touch up inside!");

    if (event == UIControlEventTouchUpOutside)
        NSLog(@"Touch up outside!");   
}

- (IBAction)buttonUpInside:(UIButton *)sender forEvent:(UIEvent *)event {
    [self buttonMethod:sender forEvent:event controlEvent:UIControlTouchUpInside];
}

- (IBAction)buttonUpOutside:(UIButton *)sender forEvent:(UIEvent *)event {
    [self buttonMethod:sender forEvent:event controlEvent:UIControlTouchUpOutside];
}
