如何在ios中的特定textView文本上创建超链接

Question

NSString *str = @"We’ll notify you before we make changes to these 
terms and give you the opportunity to review and comment on the revised 
terms before continuing to use. If you have any question just email 
me.";
NSMutableAttributedString *aStr = [[NSMutableAttributedString 
alloc]initWithString:str attributes:nil];
[str rangeOfString:@"email"]];
[self.textView setAttributedText:aStr];

这是我想在电子邮件中创建链接的文本。

Answer 1

你可以做类似的事情，

NSString *str = @"We’ll notify you before we make changes to these terms and give you the opportunity to review and comment on the revised terms before continuing to use. If you have any question just email me.";
NSMutableAttributedString *aStr = [[NSMutableAttributedString alloc]initWithString:str attributes:nil];
[aStr addAttribute:NSLinkAttributeName value:@"Your Link here" range:[str rangeOfString:@"email"]];
[self.textView setAttributedText:aStr];

更新

您可以添加字体属性使其变为粗体。例如，如果你想让We’ll notify 加粗，那么

  [aStr addAttribute:NSFontAttributeName value:[UIFont boldSystemFontOfSize:14.0] range:[str rangeOfString:@"We’ll notify"]];

在将属性文本设置为 textView 之前添加此行！

将此属性添加到您的文本视图

textview.dataDetectorTypes = UIDataDetectorTypeLink;
