前言：可能很多iOS开发者在学习之初都会对QQ的主界面的左滑与右滑动感到好奇，今天开始写我人生中的第一篇博客，即：iOS开发之Slide（主界面侧滑侧边栏）。

            首先，新建类（HomeViewController：命名随自己）继承ViewController。

            然后我们需要声明这些属性：

                

//滑动速度系数-建议在0.5-1之间。默认为0.5

@property (nonatomic,assign)CGFloat speedf;

//左侧窗控制器

@property (nonatomic,strong)UIViewController *leftVC;

//右侧滑框控制器

@property (nonatomic,strong)UIViewController *rightVC;

@property (nonatomic,strong)UIViewController *mainVC;

//点击手势控制器，是否允许点击视图恢复视图位置。默认为yes

@property (nonatomic,strong)UITapGestureRecognizer *sideslipTapGes;

//滑动手势控制器

@property (nonatomic,strong)UIPanGestureRecognizer *pan;

//侧滑窗是否关闭(关闭时显示为主页)

@property (nonatomic,assign)BOOL closed;

以及下列方法：

-(instancetype)initWithLeftView:(UIViewController *)leftVC withMainview:(UIViewController *)mainVC withRightVC:(UIViewController *)rightVC;

/**

 @brief 关闭左视图

 */

- (void)closeLeftView;

-(void)closeZPFLeftView;

/**

 @brief 打开左视图

 */

- (void)openLeftView;

-(void)showZPFleftView;

-(void)showZPFrightView;

-(void)showZPFmainView;

/**

 * 设置滑动开关是否开启

 *

 *  @param enabled YES:支持滑动手势，NO:不支持滑动手势

 */

- (void)setPanEnabled: (BOOL) enabled;

然后在.m文件中我们进行接下来的操作：

@interfaceLeftSlideViewController ()

{

    CGFloat _scalef;  //实时横向位移

}

@property (nonatomic,strong)UITableView *leftTableview;

@property (nonatomic,assign)CGFloat leftTableviewW;

@property (nonatomic,strong)UIView *contentView;

@property (nonatomic,strong)UIView *rightView;

@end

以及实现我们在.h文件中声明的方法：

-(instancetype)initWithLeftView:(UIViewController *)leftVC withMainview:(UIViewController *)mainVC withRightVC:(UIViewController *)rightVC {

    if (self = [super init]) {

        self.speedf = vSpeedFloat;

        

        self.leftVC = leftVC;

        self.mainVC = mainVC;

        self.rightVC = rightVC;

        

        //滑动手势

        self.pan = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(ZPFhandlePan:)];

        [self.mainVC.viewaddGestureRecognizer:self.pan];

        

        [self.pansetCancelsTouchesInView:YES];

        self.pan.delegate = self;

        

        self.leftVC.view.hidden = YES;

        self.rightVC.view.hidden = YES;

        

        [self.view addSubview:self.leftVC.view];

        [self.view addSubview:self.rightVC.view];

        [self.view addSubview:self.mainVC.view];

    }

   returnself;

}

#pragma mark -- ZPF左右侧滑

-(void)ZPFhandlePan:(UIPanGestureRecognizer *)rec{

    CGPoint point = [rec translationInView:self.view];

   _scalef = (point.x*_speedf+_scalef);

    

   //根据视图位置判断是左滑还是右边滑动

    if (rec.view.frame.origin.x>=0) {

        rec.view.center = CGPointMake(rec.view.center.x+_speedf*point.x,rec.view.center.y );

        rec.view.transform =CGAffineTransformScale(CGAffineTransformIdentity,1-_scalef/1000,1-_scalef/1000);

        [recsetTranslation:CGPointMake(0,0)inView:self.view];

        

        self.leftVC.view.hidden = NO;

        self.rightVC.view.hidden = YES;

        

    }else {

        rec.view.center = CGPointMake(rec.view.center.x + point.x*_speedf,rec.view.center.y);

        rec.view.transform =CGAffineTransformScale(CGAffineTransformIdentity,1+_scalef/1000,1+_scalef/1000);

        [recsetTranslation:CGPointMake(0,0)inView:self.view];

        

        self.rightVC.view.hidden = NO;

        self.leftVC.view.hidden = YES;

    }

    

   //手势结束后修正位置

   if (rec.state ==UIGestureRecognizerStateEnded) {

        if (_scalef>140*_speedf) {

            [self showZPFleftView];

        }else if (_scalef<-140*_speedf){

            [self showZPFrightView];

        }else{

            [self showZPFmainView];

            _scalef = 0;

        }

    }

}

#pragma mark -- 单击手势

-(void)handleZPFTap:(UITapGestureRecognizer *)tap {

   if (tap.state ==UIGestureRecognizerStateEnded) {

        [UIViewbeginAnimations:nilcontext:nil];

        tap.view.transform =CGAffineTransformScale(CGAffineTransformIdentity,1.0,1.0);

        tap.view.center =CGPointMake([UIScreenmainScreen].bounds.size.width/2,[UIScreenmainScreen].bounds.size.height/2);

        [UIViewcommitAnimations];

        _scalef = 0;

    }

}

#pragma mark -- 修改视图位置

//恢复位置

-(void)showZPFmainView {

    [UIViewbeginAnimations:nilcontext:nil];

   self.mainVC.view.transform =CGAffineTransformScale(CGAffineTransformIdentity,1.0,1.0);

   self.mainVC.view.center =CGPointMake([UIScreenmainScreen].bounds.size.width/2,[UIScreenmainScreen].bounds.size.height/2);

    [UIViewcommitAnimations];

}

//显示左视图

-(void)showZPFleftView {

    [UIViewbeginAnimations:nilcontext:nil];

   self.mainVC.view.transform =CGAffineTransformScale(CGAffineTransformIdentity,0.8,0.8);

   self.mainVC.view.center =CGPointMake(340,[UIScreenmainScreen].bounds.size.height/2);

    self.rightVC.view.hidden = YES;

    self.leftVC.view.hidden = NO;

    [UIViewcommitAnimations];

}

//显示右视图

-(void)showZPFrightView {

    [UIViewbeginAnimations:nilcontext:nil];

   self.mainVC.view.transform =CGAffineTransformScale(CGAffineTransformIdentity,0.8,0.8);

   self.mainVC.view.center =CGPointMake(self.view.frame.size.width*0.4,[UIScreenmainScreen].bounds.size.height/2);

    self.rightVC.view.hidden = NO;

    self.leftVC.view.hidden = YES;

    [UIViewcommitAnimations];

}

#pragma mark -- 隐藏左视图

-(void)closeZPFLeftView {

    [UIViewbeginAnimations:nilcontext:nil];

   self.mainVC.view.transform =CGAffineTransformScale(CGAffineTransformIdentity,1.0,1.0);

   self.mainVC.view.center =CGPointMake(kScreenWidth /2,kScreenHeight /2);

    self.closed = YES;

    

   self.leftTableview.center =CGPointMake(kLeftCenterX,kScreenHeight *0.5);

   self.leftTableview.transform =CGAffineTransformScale(CGAffineTransformIdentity,kLeftScale,kLeftScale);

   self.contentView.alpha =kLeftAlpha;

    

    [UIViewcommitAnimations];

    [selfremoveSingleTap];

}

#pragma mark --为了界面美观，可以选择隐藏或者显示状态栏

-(BOOL)prefersStatusBarHidden {

   returnNO;//返回NO表示要显示，返回YES即不显示

}

至此我们已建好我们所需的左右滑动的框架。   注：（如需修改左右滑动的距离，只需修改

    self.mainVC.view.transform = CGAffineTransformScale(CGAffineTransformIdentity,0.8,0.8);

    self.mainVC.view.center = CGPointMake(340,[UIScreen mainScreen].bounds.size.height/2);

）

接下来在我们的appdelegate.m文件中进行如下操作：

    self.window = [[UIWindowalloc]initWithFrame:[[UIScreenmainScreen]bounds]];

   self.window.backgroundColor = [UIColorwhiteColor];

    [self.windowmakeKeyAndVisible];

   ViewController *cc = [[ViewControlleralloc]init];

    self.mainNavigation = [[UINavigationControlleralloc]initWithRootViewController:cc];

   RightViewController *asdas = [[RightViewControlleralloc]init];

    asdas.view.backgroundColor = [UIColorwhiteColor];

   LeftViewController *left = [[LeftViewControlleralloc]init];

    left.view.backgroundColor = [UIColorwhiteColor];

   self.leftSlideVC = [[LeftSlideViewControlleralloc]initWithLeftView:leftwithMainview:self.mainNavigationwithRightVC:asdas];

    [[UINavigationBarappearance]setBarTintColor:[UIColorredColor]];

    [[UINavigationBarappearance]setTintColor:[UIColorwhiteColor]];

   self.window.rootViewController =self.leftSlideVC;

    

    

   // Override point for customization after application launch.

   returnYES;

（可能代码比较乱，毕竟帮别人加急写出来的，望大家见谅）。

然后在我们的ViewController中需要触发左右的地方进行如下操作即可：

    AppDelegate *app = (AppDelegate *)[[UIApplicationsharedApplication]delegate];

    if (isLeft == NO) {

        [app.leftSlideVC showZPFleftView];

        isLeft = YES;

    }else{

        [app.leftSlideVC closeZPFLeftView];

        isLeft = NO;

    }

注：isLeft用来判断左按钮是否按下。

好了，cmd+r   尽情的享用我们的左右滑动。
