An easy, helpful UIImageView category that generates letter initials as a placeholder for user profile images, with a randomized background color

Note: Looking for a Swift 3 compatible version? Check out the new InitialsImageView extension, rewritten entirely in Swift!

Installation

CocoaPods

Add this spec to your podfile:

pod "UIImageView-Letters"

Check out the official guide for getting started with CocoaPods.

Manual
  1. Drag the UIImageView+Letters.{h,m} files into your project
  2. Enjoy!

Usage

In the file where you want to use the category, be sure to import the file.

#import "UIImageView+Letters.h"

Methods

Call the following methods on any UIImageView instance to set the image:

  • - (void)setImageWithString:(NSString *)string
  • - (void)setImageWithString:(NSString *)string color:(UIColor *)color
  • - (void)setImageWithString:(NSString *)string color:(UIColor *)color circular:(BOOL)isCircular
  • - (void)setImageWithString:(NSString *)string color:(UIColor *)color circular:(BOOL)isCircular fontName:(NSString *)fontName
  • - (void)setImageWithString:(NSString *)string color:(UIColor *)color circular:(BOOL)isCircular textAttributes:(NSDictionary *)textAttributes

string is the string used to generate the initials. This should be a user's full name if available.

color is an optional parameter that sets the background color of the image. Pass in nil to have a color automatically generated for you.

isCircular is a boolean parameter that will automatically clip the image to a circle if enabled.

fontName is a string that specifies a custom font. Pass in nil to use the system font by default. The list of provided font identifiers can be found here.

textAttributes is an NSDictionary that allows you to specify font, text color, shadow properties, etc., for the letters text, using the keys found in NSAttributedString.h.

Example
NSString *userName = @"Michael Bluth";
UIImageView *myImgView = [[UIImageView alloc] initWithFrame:CGRectMake(10, 10, 50, 50)];
[myImgView setImageWithString:userName color:nil circular:YES];
