iOS開發 UIPanGestureRecognizer手勢抽象類別

標籤：

UIPanGestureRecognizer *panGesture = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(panIt:)];  // 初始化手勢類

[view  addGestureRecognizer:panGesture];   // 將手勢類添加給view

 

- (void)panIt:(UIPanGestureRecognizer *)panGesture

{

   CGPoint pos = [pan locationInView:panGesture.view];    // 擷取中心點

   pan.state;   // 手勢狀態
