一,工程图。

二,效果图。

三,代码。

RootViewController.h

#import <UIKit/UIKit.h> @interface RootViewController : UIViewController <UIGestureRecognizerDelegate> @end

RootViewController.m

#import "RootViewController.h" @interface RootViewController () @end @implementation RootViewController - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]; if (self) { // Custom initialization } return self; } - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view. //增加背景图 [self addView]; } #pragma -mark -functions //背景图 -(void)addView { //红色的背景图 UIView *parentView=[[UIView alloc]initWithFrame:CGRectMake(50, 100, 200, 200)]; parentView.backgroundColor=[UIColor redColor]; [self.view addSubview:parentView]; [parentView setUserInteractionEnabled:YES]; //移动的手势 UIPanGestureRecognizer *panRcognize=[[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(handlePan:)]; panRcognize.delegate=self; [panRcognize setEnabled:YES]; [panRcognize delaysTouchesEnded]; [panRcognize cancelsTouchesInView]; [parentView addGestureRecognizer:panRcognize]; } #pragma UIGestureRecognizer Handles - (void)handlePan:(UIPanGestureRecognizer *)recognizer { NSLog(@"--移动的手势-----"); } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; // Dispose of any resources that can be recreated. }
