ios 富文本点击事件响应<隐私政策···>

富文本跳转点击部分文字跳转

通常用于《XX隐私政策》

• 使用UITextView实现,设置代理

  @interface LoginView()<*UITextViewDelegate*>

• textview初始化

  UITextView *allow_textView = [[UITextView alloc] init];

  allow_textView.editable = YES;

  allow_textView.scrollEnabled = NO;

  allow_textView.textContainerInset = UIEdgeInsetsZero;

  allow_textView.textContainer.lineFragmentPadding = 0;

  allow_textView.linkTextAttributes = @{NSForegroundColorAttributeName:UIColorFromHex(0x52e4b6)};

  allow_textView.delegate = self;

  [self addSubview:allow_textView];

• 设置UITextView的富文本内容

  NSString *appName = [NSBundle mainBundle].infoDictionary[@"CFBundleDisplayName"];

  NSString *rangeStr = [NSString stringWithFormat:@"《%@隐私政策》",appName];

  NSString *protocolStr = [NSString stringWithFormat:@"阅读并同意%@",rangeStr];

  NSRange privacyRange = [protocolStr rangeOfString:rangeStr];

  NSMutableAttributedString *privacyMutableAttrStr = [[NSMutableAttributedString alloc] initWithString:protocolStr attributes:@{NSFontAttributeName:[UIFont fontWithName:@"PingFangSC-Medium" size:12.0],NSForegroundColorAttributeName:YJSetClolor(102, 102, 102, 1)}];

  //给需要 点击事件的部分添加链接

  [privacyMutableAttrStr addAttribute:NSLinkAttributeName value:@"privacy://" range:privacyRange];

  allow_textView.attributedText = privacyMutableAttrStr;

• UITextView代理事件

#pragma mark — UITextview Delegate

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

//这里调用方法跳到隐私政策页面

if ([URL.scheme isEqualToString:@"privacy"]) {

NSLog(@"%s - 隐私跳转",__func__);

return NO;

}
return YES;

}

/// 禁止编辑事件，此处可以防止双击文字出现复制粘贴菜单

-(BOOL)textViewShouldBeginEditing:(UITextView *)textView {

return NO;

}
