iOS实现图片抖动效果

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];

									}
