幻燈片顯示/隱藏工具箱

Question

我需要一些方法來隱藏工具箱，只要它是未使用的，所以我受到iPad Paper應用程序的啓發。當用戶在工具箱上向下滑動時，它滑落並且在屏幕之外，當您從屏幕底部向上滑動時，它會向上滑動。

可能有人請告訴我如何建立這個功能呢？

只需添加一個輕掃手勢識別器和viewDidLoad添加此

UISwipeGestureRecognizer *recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeup:)]; 
[recognizer setDirection:(UISwipeGestureRecognizerDirectionUp)]; 
[[self view] addGestureRecognizer:recognizer]; 
[recognizer release]; 

UISwipeGestureRecognizer *recognizer1 = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeDown:)]; 
[recognizer1 setDirection:(UISwipeGestureRecognizerDirectionDown)]; 
[[self view] addGestureRecognizer:recognizer1]; 
[recognizer1 release];
