iOS实现图片抖动效果

本文实例为大家分享了ios实现图片抖动效果的具体代码，供大家参考，具体内容如下

效果图：

核心代码：

//
// viewcontroller.m
// 图标抖动

#import "viewcontroller.h"

#define angle2rad(angle) ((angle) / 180.0 *m_pi)

@interface viewcontroller ()

@property (weak, nonatomic) iboutlet uiimageview *imagev;
@end

@implementation viewcontroller

- (void)viewdidload {
 [super viewdidload];

 self.imagev.userinteractionenabled = yes;
 //添加长按手势
 uilongpressgesturerecognizer *longpress = [[uilongpressgesturerecognizer alloc] initwithtarget:self action:@selector(longpress:)];

 [self.imagev addgesturerecognizer:longpress];
}

- (void)longpress:(uilongpressgesturerecognizer *)longpress{

 //创建动画对象
 cakeyframeanimation *anim = [cakeyframeanimation animation];

 anim.keypath = @"transform.rotation";
 anim.values = @[@(angle2rad(-5)),@(angle2rad(5))];
 anim.repeatcount = maxfloat;
// anim.duration = 1;
 anim.autoreverses = yes;


 [self.imagev.layer addanimation:anim forkey:nil];

}

- (void)didreceivememorywarning {
 [super didreceivememorywarning];
 // dispose of any resources that can be recreated.
}


@end

小编再给大家补充一段ios uiview视图抖动效果的实现代码：

/**
 * 抖动效果
 *
 * @param view 要抖动的view
 */
- (void)shakeanimationforview:(uiview *) view {
 calayer *viewlayer = view.layer;
 cgpoint position = viewlayer.position;
 cgpoint x = cgpointmake(position.x + 1, position.y);
 cgpoint y = cgpointmake(position.x - 1, position.y);
 cabasicanimation *animation = [cabasicanimation animationwithkeypath:@"position"];
 [animation settimingfunction:[camediatimingfunction functionwithname:kcamediatimingfunctiondefault]];
 [animation setfromvalue:[nsvalue valuewithcgpoint:x]];
 [animation settovalue:[nsvalue valuewithcgpoint:y]];
 [animation setautoreverses:yes];
 [animation setduration:.06];
 [animation setrepeatcount:3];
 [viewlayer addanimation:animation forkey:nil];
}
