Helpers

UIBezierPath+Image

UIScrollView+DeliveryAllEvents

Delivery all events

    - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
    {
        [self.nextResponder touchesEnded:touches withEvent:event];
    }

UIScrollView+DeliveryEvent

UIScrollView prevents all events by defaul, except panning. You can add other events to scroll view now, except panning.

I know that apple does not advocate override method in category, but it works.

    - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
    {
        if (!self.dragging)
            [self.nextResponder touchesEnded: touches withEvent:event];
        else
            [super touchesEnded: touches withEvent: event];
     }

UIView+Extension

1. remove all subviews

   - (void)removeAllSubviews;
   

2. set width, height, x and y

   - (void)setWidth: (CGFloat)width;
   - (void)setHeight: (CGFloat)heigth;
   - (void)setOriginY: (CGFloat)y;
   - (void)setOriginX: (CGFloat)x;
   

UIImage+ImageEffects

it comes from apple, you can add effects to image like ios7.

    - (UIImage *)applyLightEffect;
    - (UIImage *)applyExtraLightEffect;
    - (UIImage *)applyDarkEffect;
    - (UIImage *)applyTintEffectWithColor:(UIColor *)tintColor;

    - (UIImage *)applyBlurWithRadius:(CGFloat)blurRadius tintColor:(UIColor *)tintColor saturationDeltaFactor:(CGFloat)saturationDeltaFactor maskImage:(UIImage *)maskImage;
