NSMutableAttributedString包含NSMutableAttributedString和NSString的

Question

NSTextAttachment *attachment = [[NSTextAttachment alloc] init]; 
attachment.image = [UIImage imageNamed:@"smiley_0.png"]; 
attachment.bounds = CGRectMake(0, 0, 22, 22); 
NSMutableAttributedString *attributedString = [[NSAttributedString attributedStringWithAttachment:attachment] mutableCopy]; 
[aLabel setAttributedText:attributedString]; 

使用上面的代碼，aLabel可以顯示圖像（smiley_0.png）正確的，現在我想追加一個字符串到aLabel，任何想法？

Answer 1

嘗試使用NSMutableAttributedString的appendAttributedString您attributedString如下

NSTextAttachment *attachment = [[NSTextAttachment alloc] init]; 
attachment.image = [UIImage imageNamed:@"smiley_0.png"]; 
attachment.bounds = CGRectMake(0, 0, 22, 22); 
NSMutableAttributedString *appendedString=[[NSMutableAttributedString alloc]initWithString:@"yourString"]; 
NSMutableAttributedString *attributedString = [[NSAttributedString attributedStringWithAttachment:attachment] mutableCopy]; 
[attributedString appendAttributedString:appendedString]; 
[aLabel setAttributedText:attributedString]; 

希望它可以幫助你......！
