NSMutableAttributedString包含NSMutableAttributedString和NSString

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];

使用上面的代码，aLabel可以正确地显示图像(smiley_0.png)，现在我想给aLabel添加一个字符串，有什么想法吗？

Answer 1

尝试将appendAttributedString of NSMutableAttributedString用于attributedString，如下所示

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];

希望它能帮你.！
