IOS中对于一些控件的抖动效果

这两天在网上看到一个帖子讨论关于有些app 输入账密时候 错误的话会有抖动效果出现，然后自己琢磨了下如何实现，下面上代码！！！

首先 写一个UIView的分类

 #import <UIKit/UIKit.h>

 typedef NS_ENUM(NSInteger, QHLDirection) {
     QHLDirectionHorizontal,
     QHLDirectionVertical
 };
 @interface UIView (QHLShakes)
 - (void)shakeWithShakeDirection:(QHLDirection)shakeDirection;
 - (void)shakeWithTimes:(NSInteger)times shakeDirection:(QHLDirection)shakeDirection;
 - (void)shakeWithTimes:(NSInteger)times speed:(CGFloat)speed shakeDirection:(QHLDirection)shakeDirection;
 - (void)shakeWithTimes:(NSInteger)times speed:(CGFloat)speed range:(CGFloat)range shakeDirection:(QHLDirection)shakeDirection;
 @end

 #import "UIView+QHLShakes.h"

 @implementation UIView (QHLShakes)
 - (void)shakeWithShakeDirection:(QHLDirection)shakeDirection {
     [self shakeWithTimes: speed:0.05 range: shakeDirection:shakeDirection];
 }

 - (void)shakeWithTimes:(NSInteger)times shakeDirection:(QHLDirection)shakeDirection {
     [self shakeWithTimes:times speed:0.05 range: shakeDirection:shakeDirection];
 }

 - (void)shakeWithTimes:(NSInteger)times speed:(CGFloat)speed shakeDirection:(QHLDirection)shakeDirection {
     [self shakeWithTimes:times speed:speed range: shakeDirection:shakeDirection];
 }

 - (void)shakeWithTimes:(NSInteger)times speed:(CGFloat)speed range:(CGFloat)range shakeDirection:(QHLDirection)shakeDirection {
     [self viewShakesWithTiems:times speed:speed range:range shakeDirection:shakeDirection currentTimes: direction:];
 }
 /**
  *  @param times          震动的次数
  *  @param speed          震动的速度
  *  @param range          震动的幅度
  *  @param shakeDirection 哪个方向上的震动
  *  @param currentTimes   当前的震动次数
  *  @param direction      向哪边震动
  */
 - (void)viewShakesWithTiems:(NSInteger)times speed:(CGFloat)speed range:(CGFloat)range shakeDirection:(QHLDirection)shakeDirection currentTimes:(NSInteger)currentTimes direction:(int)direction{

     [UIView animateWithDuration:speed animations:^{
         self.transform = (shakeDirection == QHLDirectionHorizontal)? CGAffineTransformMakeTranslation(range * direction, ):CGAffineTransformMakeTranslation(, range * direction);
     } completion:^(BOOL finished) {
         if (currentTimes >= times) {
             [UIView animateWithDuration:speed animations:^{
                 self.transform = CGAffineTransformIdentity;
             }];
             return;
         }
 #pragma mark - 循环到times == currentTimes时候 会跳出该方法
         [self viewShakesWithTiems:times -
                                  speed:speed
                                  range:range
                         shakeDirection:shakeDirection
                           currentTimes:currentTimes +
                              direction:direction * -];
     }];
 }
 @en

然后在ViewController.m中

先导入头文件 #import "UIView+QHLShakes.h"

 #import "ViewController.h"
 #import "UIView+QHLShakes.h"

 #define QHLFont [UIFont boldSystemFontOfSize:17]
 #define QHLColor [UIColor purpleColor]
 #define QHLCGColor [QHLColor CGColor]

 @interface ViewController ()
 @property (nonatomic, strong) UITextField *show;
 @property (nonatomic, strong) UISegmentedControl *directBtn;
 @end

 @implementation ViewController

 - (void)viewDidLoad {
     [super viewDidLoad];
     [self setUpShowTextField];
     [self setUpBtn];
 }

 #pragma mark - show
 - (void)setUpShowTextField {
     UITextField *show = [[UITextField alloc] init];
     show.frame = CGRectMake(, , , );
     show.textAlignment = NSTextAlignmentCenter;
     show.text = @"你是猪吗?";
     show.textColor = QHLColor;
     show.layer.cornerRadius = ;
     show.layer.masksToBounds = YES;
     show.layer.borderWidth = 2.0;
     show.layer.borderColor = QHLCGColor;
     self.show = show;
     [self.view addSubview:show];
 }
 #pragma mark - btn
 - (void)setUpBtn {
     UIButton *btn = [[UIButton alloc] init];
     btn.layer.borderColor = QHLCGColor;
     btn.frame = CGRectMake(, , , );
     btn.layer.borderWidth = 2.0;
     btn.layer.cornerRadius = ;
     btn.layer.masksToBounds = YES;
     [btn setTitle:@"点我呀" forState:UIControlStateNormal];
     [btn setTitle:@"猪是你" forState:UIControlStateHighlighted];
     [btn setTitleColor:QHLColor forState:UIControlStateNormal];
     [self.view addSubview:btn];

     [btn addTarget:self action:@selector(btnDidClick) forControlEvents:UIControlEventTouchUpInside];
 }
 #pragma mark - btn 点击事件
 - (void)btnDidClick {
     [self.show shakeWithTimes: speed:0.05 range: shakeDirection:(self.directBtn.selectedSegmentIndex == )?QHLDirectionHorizontal:QHLDirectionVertical];
 }
 @end

在 - (void)viewDidLoad {} 中添加一个textField和button,然后设置相关的属性，并给button添加点击事件

当点击事件触发的时候，textField抖动！！！！

自己试了textField 和button的抖动效果 别的没试~~~

如果哪里有些错的地方 求大神指点！！！
