最近写项目发现越来越没动力了，

底层的东西实在太让人头疼了。。。

所幸研究一点好玩的东西～～那就是特效！！！

biubiubibuiubiu～～～～～～

好了废话不说 开始讲解 各种常见的不常见的甚至没见过的 iOS自带特效！

帧动画-抖动

帧动画-抖动.gif

/**
 *  抖动效果
 */
-(void)shakeAnimation{
    CAKeyframeAnimation *anima = [CAKeyframeAnimation animationWithKeyPath:@"transform.rotation"];//在这里@"transform.rotation"==@"transform.rotation.z"
    NSValue *value1 = [NSNumber numberWithFloat:-M_PI/180*4];
    NSValue *value2 = [NSNumber numberWithFloat:M_PI/180*4];
    NSValue *value3 = [NSNumber numberWithFloat:-M_PI/180*4];
    anima.values = @[value1,value2,value3];
    anima.repeatCount = MAXFLOAT;
    
    [_demoView.layer addAnimation:anima forKey:@"shakeAnimation"];
}

注意：抖动最好加一个timer时间判断 不然她会抖到你手机没电！

帧动画-弹来弹去

帧动画-弹来弹去.gif

//弹来弹去
-(void)calculationAnimation
{
    //需要实现的帧动画
    CAKeyframeAnimation *animation = [CAKeyframeAnimation animation];
    animation.keyPath = @"transform.scale";
    animation.values = @[@1.0,@1.3,@0.9,@1.15,@0.95,@1.02,@1.0];
    animation.duration = 1;
    animation.calculationMode = kCAAnimationCubic;
    //把动画添加上去
    [_demoView.layer addAnimation:animation forKey:nil];
}

这个动画 是一个我个人很喜欢的动画 可能这么看 你感觉不出 他有什么用？ 这里附加一个实例的动画 我想你们会收到启发的

4. 结束语

以上就是一些简单而且实用的 基础动画

虽然看上去gif 都挺丑的

但是我相信 如果你能把这些效果用好

不管你的app 实际内容有多少 精不精彩 至少只是一个效果 界面

就足以让你的app 发光发彩！！！

最后老规矩。

老猫在这里祝大家：永无BUG。不再加班！
