WSDrawCircleProgress, 根据UIBezierPath和CAShapeLayer自定义倒计时进度条，适用于app启动的时候设置一个倒计时关闭启动页面。可以设置进度条颜色，填充颜色，进度条宽度以及点击事件等。

公共方法：

//set track color @property (nonatomic,strong)UIColor *trackColor; //set progress color @property (nonatomic,strong)UIColor *progressColor; //set track background color @property (nonatomic,strong)UIColor *fillColor; //set progress line width @property (nonatomic,assign)CGFloat lineWidth; //set progress duration @property (nonatomic,assign)CGFloat animationDuration; /** * set complete callback * * @param lineWidth line width * @param block block * @param duration time */ - (void)startAnimationDuration:(CGFloat)duration withBlock:(DrawCircleProgressBlock )block;

使用：

- (void)viewDidLoad { [super viewDidLoad]; [self.view addSubview:self.imageView]; DrawCircleProgressButton *drawCircleView = [[DrawCircleProgressButton alloc]initWithFrame:CGRectMake(self.view.frame.size.width - 55, 30, 40, 40)]; drawCircleView.lineWidth = 2; [drawCircleView setTitle:@"跳过" forState:UIControlStateNormal]; [drawCircleView setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal]; drawCircleView.titleLabel.font = [UIFont systemFontOfSize:14]; [drawCircleView addTarget:self action:@selector(removeProgress) forControlEvents:UIControlEventTouchUpInside]; /** * progress 完成时候的回调 */ __weak ViewController *weakSelf = self; [drawCircleView startAnimationDuration:5 withBlock:^{ [weakSelf removeProgress]; }]; [self.view addSubview:drawCircleView]; }
