UIImageView-AGCInitials

AGCInitials is an Objective-C category on UIImageView to set an image placeholder with the contact's initials (letters) and an automatically generated background color.

Features

• Use it with one line of code
• The generated background color of the UIImageView will be the same for the same initials, so you can use it in your table/collection view. 😎
• You can set your own color palette for background colors
• Good test coverage 💪

How to use it - Basic

Import the category

#import "UIImageView+AGCInitials.h"

and then call the method with the contact's name:

[self.imageView agc_setImageWithInitialsFromName:@"Mick Jagger"];

The image will then contain a placeholder with the initials "MJ" and a generated background color:

How to use it - Details

• You can set the initials directly, without specifying a name, please note that in this case the background color of the image will be the same for the same initials:

- (void)agc_setImageWithInitials:(nonnull NSString*)initials;

• The initialsFromName method for @"Mick Jagger" and @"Michael Jackson" returns MJ as initials, but the background color will be probably different, since it's generated from the name:

• By default the initials are distinguished by @" ", but you can change the separator using:

- (void)agc_setImageWithInitialsFromName:(nonnull NSString*)name separatedByString:(nonnull NSString*)separator;

• You can customize the font by specifying the text attributes:

NSDictionary* initialsTextAttributes = @{ NSFontAttributeName : [UIFont systemFontOfSize:20], NSForegroundColorAttributeName : [UIColor purpleColor] };
[cellImageView agc_setImageWithInitialsFromName:@"Mick Jagger" separatedByString:@" " withTextAttributes:initialsTextAttributes];

• You can also change the color palette used to generate background colors:

#import "AGCInitialsColors.h"

And then just set your palette before using the category:

NSArray<UIColor*>* yourColorPalette; //...
[[AGCInitialsColors sharedInstance] setColorPalette:yourColorPalette];

Requirements

• iOS 7+
