iOS中添加文本链接和图片示例代码

 UITextView *textView = [[UITextView alloc] initWithFrame:CGRectMake(0, 100, 375, 100)];
 textView.backgroundColor = [UIColor cyanColor];
 //创建初始化文本的颜色，以及字体大小
 NSDictionary *dictionary = @{NSFontAttributeName:[UIFont systemFontOfSize:17],NSForegroundColorAttributeName:[UIColor yellowColor]};

 NSString * string = @" 跳转到百度\n\n 跳转到简书";
 //创建富文本
 NSMutableAttributedString *attributeStr = [[NSMutableAttributedString alloc] initWithString:string attributes:dictionary];
 //实现文本链接
 [attributeStr addAttribute:NSLinkAttributeName value:@"http://www.jianshu.com" range:[string rangeOfString:@"简书"]];
 [attributeStr addAttribute:NSLinkAttributeName value:@"http://www.baidu.com" range:[string rangeOfString:@"百度"]];
// textView.tintColor = [UIColor redColor];//调节文本链接字体的颜色

 textView.attributedText = attributeStr;
 textView.editable = NO;

- (BOOL)textView:(UITextView *)textView shouldInteractWithURL:(NSURL *)URL inRange:(NSRange)characterRange

 return YES;
}

 //文本插入图片
 NSTextAttachment *attachment = [[NSTextAttachment alloc] init];
 attachment.image = [UIImage imageNamed:@"red_2"];
 //图片大小不合适 可以调整
 attachment.bounds = CGRectMake(0, 0, 8, 8);
 NSMutableAttributedString *attachmentString = (NSMutableAttributedString *)[NSAttributedString attributedStringWithAttachment:attachment];
 //你想要插入图片的位置
 [textView.textStorage insertAttributedString:attachmentString atIndex:0];
 [textView.textStorage insertAttributedString:attachmentString atIndex:10];
