A simple UIImageView category with some extension functions.

Features

  • Support Interface Builder.
  • Set border radius for image view.
  • Set shadow for image view.
  • Rotate image view.
  • Set image view to circle.

Installation

CocoaPods

Installing UIImageView+Extension by CocoaPods.

pod 'UIImageView+Extension', '~> 0.2'

Manual Way

  • Add UIImageView+Extension.h and UIImageView+Extension.m to your project.
  • #import "UIImageView+Extension.h" where you want to use the control.
  • These files require ARC.

Usage

  • If you just want to set features in Interface Builder, just do it in Interface Builder, you need not to do anything.

Interface Builder Guide

  • If you want to control your image view in your program, you should import the category header: #import "UIImageView+Extension.h" to your .h or .m file.

API Document

Corner Radius

Setting corner radius is supported in Interface Builder.

// Set corner radius.
_imageView.cornerRadius = 10;

The method setImageCornerRadius:(version 0.2.1 and before) is not recommended to use in this version now.

Shadow

Setting shadow is supported in Interface Builder.

You can also set them in your code. Shadow color and radius are necessary to create a shadow. Shadow will be shown after you set shadow color and radius.

// Change shadow color, offset and radius.
_imageView.shadowColor = [UIColor redColor];
_imageView.shadowRadius = 1.0;
_imageView.shadowXOffset = 1.0;
_imageView.shadowYOffset = 1.0;

Rotate

You can rotate a image view infinitely by the method startRotate:withClockwise:, the first parameter is rotation time per 1 round, the second parameter decides this rotation is clockwise or anticlockwise.

// Init a shadow with color, offset and raduis.
[_imageView startRotate:2 withClockwise:NO];

// Change shadow color, offset and radius.
[_imageView stopRotate];

Blur

Setting blur is supported in Interface Builder. You can set blur style including

  • extraLight (UIBlurEffectStyleExtraLight)
  • light (UIBlurEffectStyleLight)
  • dark (UIBlurEffectStyleDark)
  • regular (UIBlurEffectStyleRegular)
  • prominent (UIBlurEffectStyleProminent)

and blur alpha(0 < alpha <= 1) directly in the Interface Builder. The default style is regular.

// Change blur style, here use the enum UIBlurEffectStyle.
[_imageView changeBlurEffectStyle:UIBlurEffectStyleExtraLight];

// Change blur alpha.
_imageView.blurAlpha = 0.5;

Circle

Setting image view to circle is supported in Interface Builder.
You must insure your image view is a square(width = height). We recommend you add Aspect Ratio constraint for your image view.

_imageView.circle = YES;
  • Tip: If you set corner radius and circle at same time, corner radius will be invalid.
