Here's a quick example of setting up an attachment to render at the start of a string.
// First you need an attributed string
NSMutableAttributedString *text = [[NSMutableAttributedString alloc] initWithString:@"This label has drawings embedded within it."];
// Create the attachment, speciying the image width and a block to draw it
KITextAttachment *attachment = [KITextAttachment textAttachmentWithWidth:128 drawingBlock: ^(CGContextRef context, CGSize size) {
[[UIColor redColor] setStroke];
CGContextFillRect(context, CGRectMake(0, 0, size.width, size.height));
}];
// Now add the attachment to your text before you set it to your label
NSAttributedString *textWithImage = [NSAttributedString attributedStringWithAttachment:attachment];
[text insertAttributedString:textWithImage atIndex:0];
label.attributedText = text;NSTextAttachment is available under the MIT license.
