给你想要做动画的view添加上,然后开始执行动画.

- (void)viewDidLoad
{
    [super viewDidLoad];

    self.dotAnimation = [JTBorderDotAnimation new];
    self.dotAnimation.animatedView = self.animatedView;
}

- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];

    [self.dotAnimation start];
}

Customization 可以定制的特性

You can easily customize the animation.

你可以很容易的定制以下的一些和动画相关的属性.

• numberPoints
• duration
• repeatCount
• pointSize
• pointColor

Example:

例子:

- (void)viewDidLoad
{
    [super viewDidLoad];

    self.dotAnimation = [JTBorderDotAnimation new];
    self.dotAnimation.animatedView = self.animatedView;

    self.dotAnimation.numberPoints = 6;
    self.dotAnimation.duration = 6.;
    self.dotAnimation.repeatCount = 3;
    self.dotAnimation.pointSize = 5.;
    self.dotAnimation.pointColor = [UIColor orangeColor];

clipsToBounds这个属性在动画开始的时候是被设置成NO的.

You can also change the speed of the animation without stopping it with:

你也可以在做动画的过程中即时修改动画的速度:

    CALayer *layer = self.animatedView.layer;

    layer.timeOffset = [layer convertTime:CACurrentMediaTime() fromLayer:nil];
    layer.beginTime = CACurrentMediaTime();
    layer.speed = 2.;
