This category of UIImage add methods to generate dynamically images from colors, adding corner radius (for each corner), tinting images, etc. Use this category if you want to add "colored style" to your app without having to generate colored graphic resources.
Right now the category supports four types of operations:
The folowing methods are used to generate a UIImage for a specific color, size and/or corner radius.
+ (UIImage*)imageWithColor:(UIColor*)color size:(CGSize)size; + (UIImage*)imageWithColor:(UIColor*)color size:(CGSize)size cornerRadius:(CGFloat)cornerRadius; + (UIImage*)imageWithColor:(UIColor*)color size:(CGSize)size cornerInset:(UICornerInset)cornerInset;
These methods are perfect to use inside
UIImageViews if you are plannig to add a specific background color with a corner radius but you don't want to use
QuartzCore. Also, you can specify which corner you want to round.
+ (UIImage*)resizableImageWithColor:(UIColor*)color; + (UIImage*)resizableImageWithColor:(UIColor*)color cornerRadius:(CGFloat)cornerRadius; + (UIImage*)resizableImageWithColor:(UIColor*)color cornerInset:(UICornerInset)cornerInset;
You can use these methods to get a corner rounded image version from a current image.
- (UIImage*)imageWithRoundedBounds; - (UIImage*)imageWithCornerRadius:(CGFloat)cornerRadius; - (UIImage*)imageWithCornerInset:(UICornerInset)cornerInset; - (BOOL)isValidCornerInset:(UICornerInset)cornerInset;
In order to avoid to generate multiple versions of the same image to use in different states (in
UIButton for example), your designers can just create a single version and with these methods you can generate tinted versions of the same image.
+ (UIImage*)imageNamed:(NSString *)name tintColor:(UIColor*)color style:(UIImageTintedStyle)tintStyle; - (UIImage*)tintedImageWithColor:(UIColor*)color style:(UIImageTintedStyle)tintStyle;
You can use the following tint styles:
UIImageTintedStyleKeepingAlphato keep transaprent pixels and tint only those that are not translucid.
UIImageTintedStyleOverAlphato keep non transparent pixels and tint only those that are translucid.
You can easily create an image by superposing two images. Calling the method:
- (UIImage *)imageAddingImage:(UIImage*)image offset:(CGPoint)offset;
The result is an image with the caller image as background and the given image as a top image. Also, you can specify an offset for the top image.
You can create linear gradient images (with two colors or more) using the following methods:
+ (UIImage*)imageWithGradient:(NSArray*)colors size:(CGSize)size direction:(UIImageGradientDirection)direction; + (UIImage*)resizableImageWithGradient:(NSArray*)colors size:(CGSize)size direction:(UIImageGradientDirection)direction;
The first method returns an image with a gradient using the specified colors and direction of the given size. The second method returns the smallest resizable image that can generate the desired gradient for the given size.
This category take care of scaling properties depending of the device resolution (retina or not) or the original image scale property.
All static methods cache images so two consequtives calls with the same parameters returns the same image.
