 3 @interface SpringViewController ()
 4 @property (weak, nonatomic) IBOutlet UIImageView *imageView;
 5 
 6 @end

 8 @implementation SpringViewController
 9 
10 - (void)viewDidLoad {
11     [super viewDidLoad];
12     //1.动画时长 2.延迟时长 3.类似于弹簧的效果(0-1) 4.初始的速度 5.动画过渡效果 6. 开始动画 7.完成动画
13     
14     [UIView animateWithDuration:2 delay:2 usingSpringWithDamping:0.8 initialSpringVelocity:18 options:UIViewAnimationOptionCurveEaseInOut animations:^{
15         self.imageView.center = self.view.center;
16     } completion:^(BOOL finished) {
17         
18     }];
