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

 1 #import <UIKit/UIKit.h>
 2 
 3 typedef NS_ENUM(NSInteger, QHLDirection) {
 4     QHLDirectionHorizontal,
 5     QHLDirectionVertical
 6 };
 7 @interface UIView (QHLShakes)
 8 - (void)shakeWithShakeDirection:(QHLDirection)shakeDirection;
 9 - (void)shakeWithTimes:(NSInteger)times shakeDirection:(QHLDirection)shakeDirection;
10 - (void)shakeWithTimes:(NSInteger)times speed:(CGFloat)speed shakeDirection:(QHLDirection)shakeDirection;
11 - (void)shakeWithTimes:(NSInteger)times speed:(CGFloat)speed range:(CGFloat)range shakeDirection:(QHLDirection)shakeDirection;
12 @end
13 
14 
15 
16 #import "UIView+QHLShakes.h"
17 
18 @implementation UIView (QHLShakes)
19 - (void)shakeWithShakeDirection:(QHLDirection)shakeDirection {
20     [self shakeWithTimes:10 speed:0.05 range:5 shakeDirection:shakeDirection];
21 }
22 
23 - (void)shakeWithTimes:(NSInteger)times shakeDirection:(QHLDirection)shakeDirection {
24     [self shakeWithTimes:times speed:0.05 range:5 shakeDirection:shakeDirection];
25 }
26 
27 - (void)shakeWithTimes:(NSInteger)times speed:(CGFloat)speed shakeDirection:(QHLDirection)shakeDirection {
28     [self shakeWithTimes:times speed:speed range:5 shakeDirection:shakeDirection];
29 }
30 
31 - (void)shakeWithTimes:(NSInteger)times speed:(CGFloat)speed range:(CGFloat)range shakeDirection:(QHLDirection)shakeDirection {
32     [self viewShakesWithTiems:times speed:speed range:range shakeDirection:shakeDirection currentTimes:0 direction:1];
33 }
34 /**
35  *  @param times          震动的次数
36  *  @param speed          震动的速度
37  *  @param range          震动的幅度
38  *  @param shakeDirection 哪个方向上的震动
39  *  @param currentTimes   当前的震动次数
40  *  @param direction      向哪边震动
41  */
42 - (void)viewShakesWithTiems:(NSInteger)times speed:(CGFloat)speed range:(CGFloat)range shakeDirection:(QHLDirection)shakeDirection currentTimes:(NSInteger)currentTimes direction:(int)direction{
43     
44     [UIView animateWithDuration:speed animations:^{
45         self.transform = (shakeDirection == QHLDirectionHorizontal)? CGAffineTransformMakeTranslation(range * direction, 0):CGAffineTransformMakeTranslation(0, range * direction);
46     } completion:^(BOOL finished) {
47         if (currentTimes >= times) {
48             [UIView animateWithDuration:speed animations:^{
49                 self.transform = CGAffineTransformIdentity;
50             }];
51             return;
52         }
53 #pragma mark - 循环到times == currentTimes时候 会跳出该方法
54         [self viewShakesWithTiems:times - 1
55                                  speed:speed
56                                  range:range
57                         shakeDirection:shakeDirection
58                           currentTimes:currentTimes + 1
59                              direction:direction * -1];
60     }];
61 }
62 @en

然后在ViewController.m中

先导入头文件 #import "UIView+QHLShakes.h"

 1 #import "ViewController.h"
 2 #import "UIView+QHLShakes.h"
 3 
 4 #define QHLFont [UIFont boldSystemFontOfSize:17]
 5 #define QHLColor [UIColor purpleColor]
 6 #define QHLCGColor [QHLColor CGColor]
 7 
 8 @interface ViewController ()
 9 @property (nonatomic, strong) UITextField *show;
10 @property (nonatomic, strong) UISegmentedControl *directBtn;
11 @end
12 
13 @implementation ViewController
14 
15 - (void)viewDidLoad {
16     [super viewDidLoad];
17     [self setUpShowTextField];
18     [self setUpBtn];
19 }
20 
21 #pragma mark - show
22 - (void)setUpShowTextField {
23     UITextField *show = [[UITextField alloc] init];
24     show.frame = CGRectMake(30, 360, 270, 30);
25     show.textAlignment = NSTextAlignmentCenter;
26     show.text = @"你是猪吗?";
27     show.textColor = QHLColor;
28     show.layer.cornerRadius = 5;
29     show.layer.masksToBounds = YES;
30     show.layer.borderWidth = 2.0;
31     show.layer.borderColor = QHLCGColor;
32     self.show = show;
33     [self.view addSubview:show];
34 }
35 #pragma mark - btn
36 - (void)setUpBtn {
37     UIButton *btn = [[UIButton alloc] init];
38     btn.layer.borderColor = QHLCGColor;
39     btn.frame = CGRectMake(30, 430, 270, 30);
40     btn.layer.borderWidth = 2.0;
41     btn.layer.cornerRadius = 5;
42     btn.layer.masksToBounds = YES;
43     [btn setTitle:@"点我呀" forState:UIControlStateNormal];
44     [btn setTitle:@"猪是你" forState:UIControlStateHighlighted];
45     [btn setTitleColor:QHLColor forState:UIControlStateNormal];
46     [self.view addSubview:btn];
47     
48     [btn addTarget:self action:@selector(btnDidClick) forControlEvents:UIControlEventTouchUpInside];
49 }
50 #pragma mark - btn 点击事件
51 - (void)btnDidClick {
52     [self.show shakeWithTimes:20 speed:0.05 range:3 shakeDirection:(self.directBtn.selectedSegmentIndex == 0)?QHLDirectionHorizontal:QHLDirectionVertical];
53 }
54 @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！！！
