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:10 speed:0.05 range:5 shakeDirection:shakeDirection];
}

- (void)shakeWithTimes:(NSInteger)times shakeDirection:(QHLDirection)shakeDirection {
    [self shakeWithTimes:times speed:0.05 range:5 shakeDirection:shakeDirection];
}

- (void)shakeWithTimes:(NSInteger)times speed:(CGFloat)speed shakeDirection:(QHLDirection)shakeDirection {
    [self shakeWithTimes:times speed:speed range:5 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:0 direction:1];
}
/**
 *  @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, 0):CGAffineTransformMakeTranslation(0, 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 - 1
                                 speed:speed
                                 range:range
                        shakeDirection:shakeDirection
                          currentTimes:currentTimes + 1
                             direction:direction * -1];
    }];
}
@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(30, 360, 270, 30);
    show.textAlignment = NSTextAlignmentCenter;
    show.text = @"你是猪吗?";
    show.textColor = QHLColor;
    show.layer.cornerRadius = 5;
    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(30, 430, 270, 30);
    btn.layer.borderWidth = 2.0;
    btn.layer.cornerRadius = 5;
    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:20 speed:0.05 range:3 shakeDirection:(self.directBtn.selectedSegmentIndex == 0)?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！！！
