iOS UIlabel添加照片 UITextView 文字/照片点击事件

根据产品需求需要文本的行末添加一个图标或者图片，并可实现部分文字的点击和照片的点击事件

效果图

方案1:添加的图片是iconfont图标。iconfont，从字面上就能理解它就是字体，让开发者像使用字体一样使用图标。

    UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(50, 160, 280, 40)];
    [self.view addSubview:label];
    label.font = [UIFont fontWithName:@"iconfont" size:15];//设置label的字体
    label.text = @"这是用label显示的iconfont  \U0000e60c";

如果不显示，请检查一下iconfont的资源文件是否在工程目录下。

plist文件配置

方案2:通过 NSMutableAttributedString 在文本末尾添加一个照片

    UILabel *titleLabel = [[UILabel alloc]init];
    titleLabel.frame = CGRectMake(10, 300, 100, 200);
    titleLabel.backgroundColor = [UIColor redColor];
    [self.view addSubview:titleLabel];

    NSTextAttachment *attachment = [[NSTextAttachment alloc]init];
    attachment.image = [UIImage imageNamed:@"eys"];
    NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc]initWithString:@"我的后面跟着一个照片"];
    [attributedString addAttribute:NSForegroundColorAttributeName value:[UIColor blueColor] range:NSMakeRange(0, 10)];
    [attributedString addAttribute:NSFontAttributeName value:[UIFont systemFontOfSize:20] range:NSMakeRange(0, 10)];
    NSAttributedString *attachmentString = [NSAttributedString attributedStringWithAttachment:attachment];
    [attributedString insertAttributedString:attachmentString atIndex:10];
    titleLabel.attributedText = attributedString;
    titleLabel.numberOfLines = 0;
    [titleLabel sizeToFit];

UITextView 文字/照片点击事件

 NSMutableAttributedString *attributeString2 = [[NSMutableAttributedString alloc]initWithString:@"哈哈哈哈哈哈哈哈，你还没有中奖，赶快去参加活动"];
    [attributeString2 addAttribute:NSLinkAttributeName value:@"click://" range:[[attributeString2 string]rangeOfString:@"参加活动"]];
    NSTextAttachment *attachment2 = [[NSTextAttachment alloc]init];
    attachment2.image = [UIImage imageNamed:@"eys"];
    attachment2.bounds = CGRectMake(0, 0, 15, 15);
    NSAttributedString *attachmentString2 = [NSAttributedString attributedStringWithAttachment:attachment2];
    NSMutableAttributedString *imgAttribute = [[NSMutableAttributedString alloc]initWithAttributedString:attachmentString2];
    [imgAttribute addAttribute:NSLinkAttributeName value:@"IMGURL://" range:NSMakeRange(0, imgAttribute.length)];
    [attributeString2 insertAttributedString:imgAttribute atIndex:[attributeString2 string].length];

    UITextView *textView  = [[UITextView alloc]initWithFrame:CGRectMake(20,400 , 200, 220)];
    [self.view addSubview:textView];
    textView.attributedText = attributeString2;
    textView.linkTextAttributes = @{NSForegroundColorAttributeName:[UIColor blueColor],NSUnderlineColorAttributeName:[UIColor grayColor]};
    textView.font = [UIFont systemFontOfSize:18];
    textView.textAlignment = NSTextAlignmentLeft;
    textView.backgroundColor = [UIColor brownColor];
    textView.delegate = self;
    textView.editable = NO;
    textView.scrollEnabled = NO;
    [self.view addSubview:textView];
    self.curentView = textView;

UItextView的代理方法

-(BOOL)textView:(UITextView *)textView shouldInteractWithURL:(NSURL *)URL inRange:(NSRange)characterRange interaction:(UITextItemInteraction)interaction {
    
    NSLog(@"打印获取到的url的字符串为----%@",[URL scheme]);
    
    if ([[URL scheme] isEqualToString:@"click"]) {

        NSLog(@"执行了文字的点击事件");
        UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:@"提示" message:@"文字被点击了" delegate:nil cancelButtonTitle:nil otherButtonTitles:@"我知道了", nil];
        [alertView show];
        
        return NO;
        
    }else if ([[URL scheme] isEqualToString:@"IMGURL"]) {
        
        UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:@"提示" message:@"照片被点击了" delegate:nil cancelButtonTitle:nil otherButtonTitles:@"我知道了", nil];
        [alertView show];
        NSLog(@"执行了点击末尾的照片");
        
    }
    return YES;
 
}
