本文實例為大家分享了iOS實現抽屜效果的全部代碼，供大家參考，具體內容如下

iOS實現簡易抽屜效果，代碼：

@interface ViewController () {
  UIView* _leftView;
}
 
@end
 
@implementation ViewController
 
- (void)viewDidLoad {
  [super viewDidLoad];
  // Do any additional setup after loading the view, typically from a nib.
   
  _leftView = [[UIView alloc] init];
  //把左側邊的view先隱藏
  _leftView.frame = CGRectMake(-200, 0, 200, self.view.frame.size.height);
  _leftView.backgroundColor = [UIColor greenColor];
  [self.view addSubview:_leftView];
   
  UIPanGestureRecognizer* pan = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(handlePan:)];
  [self.view addGestureRecognizer:pan];
}
 
- (void)handlePan:(UIPanGestureRecognizer*) recognizer {
  CGPoint translation = [recognizer translationInView:self.view];
  //增量後的x坐標位置
  CGFloat Xresult = translation.x + _leftView.frame.origin.x;
   
  //向右
  if (translation.x >= 0) {
    //leftView已全部拉出，則無法再向右
    if (_leftView.frame.origin.x >= 0 || Xresult >= 0) {
      _leftView.frame = CGRectMake(0, 0, 200, self.view.frame.size.height);
       
      return;
    }
  } else if (translation.x < 0) {//向左
    //leftView已全部收回，則無法再向左
    if (_leftView.frame.origin.x <= -200 || Xresult <= -200) {
      _leftView.frame = CGRectMake(-200, 0, 200, self.view.frame.size.height);
      return;
    }
  }
   
  CGRect frame = _leftView.frame;
  frame.origin.x += translation.x;
  _leftView.frame = frame;
   
  //清空移動的距離，這是關鍵
  [recognizer setTranslation:CGPointZero inView:recognizer.view];
   
  //做彈回效果，以中軸為界限
  if (recognizer.state == UIGestureRecognizerStateEnded) {
    if (_leftView.frame.origin.x > -100) {
      [self closeView:NO];
    } else {
      [self closeView:YES];
    }
  }
}
 
- (void)closeView:(BOOL)close {
  if (close) {
    [self moveView:CGRectMake(-200, 0, 200, self.view.frame.size.height)];
  } else {
    [self moveView:CGRectMake(0, 0, 200, self.view.frame.size.height)];
  }
}
 
- (void)moveView:(CGRect)frame {
  [UIView animateWithDuration:0.3 animations:^{
    _leftView.frame = frame;
  } completion:^(BOOL finished) {
     
  }];
}

iOS實現雙邊抽屜效果，代碼：

#import "PathView.h"
#import "UIView+Additions.h"
 
@implementation PathView
 
- (instancetype)init {
  self = [super init];
  if (self) {
    [self setupGestureRecognizer];
  }
  return self;
}
 
- (void)setupGestureRecognizer {
  UIPanGestureRecognizer* pan = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(handlePan:)];
  [self addGestureRecognizer:pan];
}
 
- (void)handlePan:(UIPanGestureRecognizer*)recognizer {
  CGPoint translation = [recognizer translationInView:self];
   
  CGFloat Xresult = translation.x + self.left;
   
  if (translation.x >= 0) {//向右
    if (self.left >= _leftWidth || Xresult >= _leftWidth) {
      self.frame = CGRectMake(_leftWidth, 0, self.width, self.height);
      return;
    }
  }
  else if (translation.x < 0) {//向左
    if (self.left <= -_rightWidth || Xresult <= -_rightWidth) {
      self.frame = CGRectMake(-_rightWidth, 0, self.width, self.height);
      return;
    }
  }
   
  self.left += translation.x;
   
  if (recognizer.state == UIGestureRecognizerStateEnded) {
    if (self.left > _leftWidth / 2) {
      [self openLeft:YES openRight:NO];
    }
     
    else if (self.left < -(_rightWidth / 2)) {
      [self openLeft:NO openRight:YES];
    }
     
    else {
      [self openLeft:NO openRight:NO];
    }
  }
   
  //清空移動的距離
  [recognizer setTranslation:CGPointZero inView:recognizer.view];
}
 
- (void)openLeft:(BOOL)left openRight:(BOOL)right {
  if (!left && !right) {
    [self moveView:CGRectMake(0, 0, self.width, self.height)];
     
  } else if (!left && right) {
    [self moveView:CGRectMake(-_rightWidth, 0, self.width, self.height)];
     
  } else if (left && !right) {
    [self moveView:CGRectMake(_leftWidth, 0, self.width, self.height)];
     
  }
}
 
- (void)moveView:(CGRect)frame {
  [UIView animateWithDuration:0.3 animations:^{
    self.frame = frame;
  } completion:^(BOOL finished) {
     
  }];
}

上面是實現的具體內容，所以不做多少注釋，只不過把手勢移到view裡面，讓view自己改變自己的frame；再有就是添加了兩個屬性，來指定左右兩邊各自抽屜抽出的寬度，某一邊不需要，只要設置為0就好了。

以上就是本文的全部內容，希望能夠幫助大家順利實現iOS抽屜效果。
