更改引号内的文本颜色

Question

NSString *message = @"This part: \"Is in quotations\"";

我想知道是否可以为引号内的NSString部分涂上不同的颜色？我理解这个例子：Is it possible to change color of single word in UITextView and UITextField但不知道如何将它转换为我的例子，因为我有多个slach。

Answer 1

我已经写了一个xcode游乐场示例（在swift中因为我很懒）会在引号内为任何颜色着色

var s = "this is a string with \"quotations\" that has multiple \"quotations\" blah blah"

var split:[String] = s.componentsSeparatedByString("\"")

var att:NSMutableAttributedString = NSMutableAttributedString()

for i in 0..<split.count {

    var temp:NSMutableAttributedString

    if((i+1)%2 == 0){ //every even index is something between quotations because of how we split
        temp = NSMutableAttributedString(string: "\"" + split[i] + "\"")
        temp.addAttribute(NSForegroundColorAttributeName, value: UIColor.greenColor(), range: NSRange(location: 0, length: temp.string.characters.count))
    }
    else {
        temp = NSMutableAttributedString(string: split[i])
        temp.addAttribute(NSForegroundColorAttributeName, value: UIColor.whiteColor(), range: NSRange(location: 0, length: temp.string.characters.count))
    }

    att.appendAttributedString(temp)

}

结果：

我相信它很容易根据您的需要重新调整（或进入Obj-c），或者可以在自己的操场上玩它
