也没有什么好说的，方法都差不多，只要记得当你想要同时实现两个或多个手势的话，要遵守<UIGestureRecognizerDelegate>协议，闲言休叙，直接上代码：
#import "RootViewController.h"
#import "RootView.h" @interface RootViewController () <UIGestureRecognizerDelegate> // 手势识别器代理
@property (nonatomic, strong) RootView *rootView; @end @implementation RootViewController - (void)loadView {
self.rootView = [[RootView alloc] initWithFrame:[UIScreen mainScreen].bounds];
self.view = self.rootView;
} - (void)viewDidLoad {
[super viewDidLoad]; // 轻拍
[self tapGesture]; // 平移
//[self panGesture]; // 缩放（捏合）
[self pinchGesture]; // 旋转
[self rotationGesture]; // 长按
[self longPressGesture]; // 轻扫（滑动）
[self swipeGesture]; // 屏幕边缘轻扫（滑动）
