添加UITapGestureRecognizer到NSAttributed文本射程(Add UITa

我有一个属性串设置如下：

var range = (showStr as NSString).rangeOfString(spellingStr)
var attributedString = NSMutableAttributedString(string:showStr)
attributedString.addAttribute(NSForegroundColorAttributeName, value: ezGreen, range: range)

我想点击手势添加只是，我设置为绿色的范围内。

是否有触摸的属性？我将如何设置点击手势只是为了spellingStr一部分？

我为标签和字符串的所有代码如下：

var showStr:NSString = "Showing results for \(searchT)."
println("SearchTerm:\(searchT)")
showingLabel.textColor = .blackColor()

var range = (showStr as NSString).rangeOfString(searchT)
var attributedString = NSMutableAttributedString(string:showStr)
attributedString.addAttribute(NSForegroundColorAttributeName, value: ezGreen , range: range)

showingLabel.attributedText = attributedString
showingLabel.font = UIFont.systemFontOfSize(17)
showingLabel.numberOfLines = 0
showingLabel.lineBreakMode = NSLineBreakMode.ByWordWrapping
var showHeight:CGFloat = heightForView(showingLabel.text!, UIFont.systemFontOfSize(17), maxLabelWidth)
showingLabel.frame = CGRectMake(20, heightOfCor, maxLabelWidth, showHeight)
heightOfCor += showHeight
bgBlack.addSubview(showingLabel)

我已经只是创造一个UIButton并将其设置到该行文本的确切框架做了。

下面是如何做到这一点在Objective-C的例子：

NSRange range = [self.textView.text rangeOfString:@"The string of text you want to tap"];
self.textView.selectedRange = range;
UITextRange *textRange = [self.textView selectedTextRange];
CGRect textRect = [self.textView firstRectForRange:textRange];
CGRect convertedRect = [self.view convertRect:textRect fromView:self.textView];

UIButton *button = [[UIButton alloc]initWithFrame:convertedRect];
[button setBackgroundColor:[UIColor clearColor]];
[button addTarget:self action:@selector(textTapped:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:button];
[self.view bringSubviewToFront:button];

注意：调用此之前，您应该已经设置你的属性串，并将其添加到您的UITextView。此外，请确保你让你的TextView里面选择（但如果你不想亮点等禁用的用户交互）
