iOS-工具方法-UIView

所有繼承自UIView的控件都可以調用該方法添加邊框

UIView添加邊框

//view添加邊框
//參數說明，view->控件、borderWidth->邊框寬度、borderColor->邊框顏色、cornerradius->圓角、masksToBounds ->視圖的圖層上的子圖層,如果超出父圖層的部分就截取掉.
+ (void)view:(UIView *)view borderWidth:(CGFloat)width borderColor:(UIColor *)color cornerradius:(CGFloat)cornerradius masksToBounds:(BOOL)masksToBounds
{
    view.layer.borderWidth=width;
    if (color==nil) {
        color=[UIColor whiteColor];
    }
    view.layer.borderColor=color.CGColor;
    if (masksToBounds==YES) {
        view.layer.masksToBounds=masksToBounds;
    }
    view.layer.cornerRadius=cornerradius;
}

UIImage執行360°旋轉動畫

//360旋轉動畫 
+ (void)startAnimation:(UIImageView *)parabolaImageV duration:(CGFloat)duration
{
    CABasicAnimation* rotationAnimation;
    rotationAnimation = [CABasicAnimation animationWithKeyPath:@"transform.rotation.z"];
    rotationAnimation.toValue = [NSNumber numberWithFloat: M_PI * 2.0 ];
    rotationAnimation.duration =duration;
    rotationAnimation.cumulative = YES;
    rotationAnimation.repeatCount =100;
    [parabolaImageV.layer addAnimation:rotationAnimation forKey:@"rotationAnimation"];


}
