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.}

以上代码是有关Android程序开发之给背景图加上移动的手势的全部内容，希望对大家有所帮助！
