如何讓pageController控制UIImageView？

Question

我想要一個UIImageView向左滑動，UIImageView將更改圖像，此時，pageController +1，如果向右滑動，pageContoller -1，並顯示上一張圖像......我該如何實現它？任何簡單的代碼？你好。

Answer 1

只需將UISwipeGestureRecognizer附加到UIImageView。當手勢識別器觸發時，您會檢查它的方向，然後更改圖像並相應地更新pageController。

UIGestureRecognizer *recognizer; 

recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(next:)]; 
UISwipeGestureRecognizer *swipeLeftRecognizer = (UISwipeGestureRecognizer *)recognizer; 
swipeLeftRecognizer.direction = UISwipeGestureRecognizerDirectionLeft; 
[self.view addGestureRecognizer:swipeLeftRecognizer]; 
swipeLeftRecognizer=nil; 
[recognizer release]; 

recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(prev:)]; 
UISwipeGestureRecognizer *swipeRightRecognizer = (UISwipeGestureRecognizer *)recognizer; 
swipeRightRecognizer.direction = UISwipeGestureRecognizerDirectionRight; 
[self.view addGestureRecognizer:swipeRightRecognizer]; 
swipeLeftRecognizer=nil; 
[recognizer release];
