在显示在窗口的控制器上添加三个view（如果只需要往一边滑动就只加2个view）

先声明三个view

#import "ViewController.h"@interface ViewController ()
@property(nonatomic, weak) UIView *mainV;
@property(nonatomic, weak) UIView *leftV;
@property(nonatomic, weak) UIView *rightV;
@end

添加view到控制器view上

#pragma mark - 添加子控件
- (void)setUpChildViews {UIView *leftV = [[UIView alloc]initWithFrame:self.view.bounds];leftV.backgroundColor = [UIColor orangeColor];[self.view addSubview:leftV];_leftV = leftV;UIView *rightV = [[UIView alloc]initWithFrame:self.view.bounds];rightV.backgroundColor = [UIColor groupTableViewBackgroundColor];[self.view addSubview:rightV];_rightV = rightV;UIView *mainV = [[UIView alloc]initWithFrame:self.view.bounds];mainV.backgroundColor = [UIColor yellowColor];[self.view addSubview:mainV];_mainV = mainV;
}- (void)viewDidLoad {[super viewDidLoad];//添加子控件[self setUpChildViews];//添加Pan手势UIPanGestureRecognizer *pan = [[UIPanGestureRecognizer alloc]initWithTarget:self action:@selector(pan:)];[self.view addGestureRecognizer:pan];//添加点按手势，在主视图上任意位置点击回到屏幕开始位置UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(tap)];[self.view addGestureRecognizer:tap];}

#pragma mark - 手势识别方法
#define targetL -230
#define targetR 200
#define screenW [UIScreen mainScreen].bounds.size.width
- (void)pan:(UIPanGestureRecognizer *)pan {//获取手势移动的位置CGPoint tranP = [pan translationInView:self.view];//获取x的偏移量CGFloat offsetX = tranP.x;//修改mainV的frame_mainV.frame = [self frameWithOffsetX:offsetX];//判断mainV的x是否大于0[self observeValueForKeyPath:nil ofObject:nil change:nil context:nil];//复位[pan setTranslation:CGPointZero inView:self.view];//判断当手势结束的时候，定位if (pan.state == UIGestureRecognizerStateEnded) {CGFloat target = 0;if (_mainV.frame.origin.x > screenW * 0.5) {//定位到右边target = targetR;}else if(CGRectGetMaxX(_mainV.frame) < screenW * 0.5) {//定位到左边target = targetL;}//获取X轴需要移动的偏移量CGFloat offsetX = target - _mainV.frame.origin.x;[UIView animateWithDuration:0.25 animations:^{_mainV.frame = target == 0 ? self.view.bounds : [self frameWithOffsetX:offsetX];}];}}

- (void)tap {[UIView animateWithDuration:0.25 animations:^{_mainV.frame = self.view.bounds;}];}

#define kMaxY 80
#pragma mark - 根据offsetX计算mainV的frame
- (CGRect)frameWithOffsetX:(CGFloat)offsetX {//获取上一次的frameCGRect frame = _mainV.frame;//获取屏幕的高度CGFloat screenH = [UIScreen mainScreen].bounds.size.height;//获取屏幕的宽度//CGFloat screenW = [UIScreen mainScreen].bounds.size.width;//X轴平移一点对应Y轴需要平移的距离CGFloat offsetY = offsetX * kMaxY / screenW;//获取上一次的高度CGFloat preH = frame.size.height;//获取上一次的宽度CGFloat preW = frame.size.width;//获取当前高度CGFloat curH = preH - 2 * offsetY;//如果是向左滑动if(frame.origin.x < 0) {curH = preH + 2 * offsetY;}//获取尺寸的缩放比例CGFloat scale = curH / preH;//获取当前宽度CGFloat curW = preW * scale;//获取当前xframe.origin.x += offsetX;//获取当前yCGFloat y = (screenH - curH) / 2;frame.origin.y = y;frame.size.width = curW;frame.size.height = curH;return frame;}

- (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary<NSString *,id> *)change context:(void *)context {if(_mainV.frame.origin.x > 0) {//往右边滑动_rightV.hidden = YES;}else if(_mainV.frame.origin.x < 0) {//往左边滑动_rightV.hidden = NO;}}

如果想要在mainV主视图中显示tableView，就新创建一个TableViewController，在这里面显示tableView的数据，

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {return 30;
}- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {static NSString *ID = @"cell";UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:ID];if(cell == nil) {cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:ID];}cell.textLabel.text = [NSString stringWithFormat:@"第%ld行", indexPath.row];return cell;
}

再创建一个在storyboard中显示的控制器XXMainViewController，继承自实现了抽屉效果的ViewController，并且在storyboard中将class改为这个控制的类名，还要将显示tableView的控制成为他的子控制器

- (void)viewDidLoad {[super viewDidLoad];XXViewController *vc = [[XXViewController alloc]init];vc.view.frame = self.view.bounds;//让vc成为主视图控制器的子控制器[self addChildViewController:vc];//主视图展示tableView[self.mainV addSubview:vc.view];}

为了在XXMainViewController中只能访问mainV而不能修改他的值，所以将子控件的view暴露在ViewController.h中，并添加read-only

#import <UIKit/UIKit.h>@interface ViewController : UIViewController
@property(nonatomic, weak, readonly) UIView *mainV;
@property(nonatomic, weak, readonly) UIView *leftV;
@property(nonatomic, weak, readonly) UIView *rightV;
@end
