我有這麼多代碼的遊戲,但它的大部分是一遍又一遍地重複相同的空白只有一個按鈕的差異。如何在一個按鈕的地方做一個變量?
我簡化了代碼用於此目的:
-(void)button1Action {
if (CGRectIntersectsRect(button1.frame, image1.frame)) {
//button 1 is used a few times between these two brackets
}
}
-(void)button2Action {
if (CGRectIntersectsRect(button2.frame, image1.frame)) {
//button 2 is used a few times between these two brackets
}
}
-(void)button3Action {
if (CGRectIntersectsRect(button3.frame, image1.frame)) {
//button 3 is used a few times between these two brackets
}
}
有我做一個空隙用這樣的一種方式?:
-(void)buttonXAction {
if (CGRectIntersectsRect(buttonX.frame, image1.frame)) {
//button X is used a few times between these two brackets
}
}
謝謝!
我想這是我需要的東西!但是,在這種情況下如何聲明發件人是什麼? – Vince
您可以將操作添加到每個按鈕,如下所示:[button1 addTarget:self action:@selector(buttonAction:)forControlEvents:UIControlEventTouchUpInside]; – DominicanCoder
爲每個按鈕做這件事,他們將成爲「發件人」的論據。這將執行調用該方法的每個按鈕的代碼。 – DominicanCoder
