iOSUITextView富文本展示文字图片

Demo下载地址

要在一个UITextView中既展示图片和文字，主要代码如下：

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{
    //获得需要展示的图片
    UIImage *image = info[UIImagePickerControllerEditedImage];
    if (!image ) {
        image = info[UIImagePickerControllerOriginalImage];
    }
    self.pictureImg = image;
    
    //富文本添加文字、图片
    NSMutableAttributedString *attri = [[NSMutableAttributedString alloc] initWithAttributedString:self.contentTV.attributedText];
    [attri addAttribute:NSFontAttributeName value:[UIFont systemFontOfSize:18] range:NSMakeRange(0, self.contentTV.text.length)];
    
    //添加图片附件
    NSTextAttachment *attch = [[NSTextAttachment alloc] init];
    attch.image = image;
    //大小需要根据图片去相应适配缩放比例；位置需要根据文字自适应高度
    attch.bounds = CGRectMake(0, -5, ScreenWidth - 10,200);
    
    NSAttributedString *string = [NSAttributedString attributedStringWithAttachment:attch];
    [attri appendAttributedString:string];
    self.contentTV.attributedText = attri;

    [picker dismissViewControllerAnimated:YES completion:nil];
}

使用 NSAttributedString属性来实现，这种适合上下来布局，并不适合图片上下左右被文字包围布局。
