How to use NSRange
提问by Ameya Vaidya
I am using NSRange with an Attributed string, but I don't fully understand which parts of the text will be bolded and which are not. This is what I tried:
我正在使用带有属性字符串的 NSRange,但我不完全理解文本的哪些部分将加粗,哪些不加粗。这是我尝试过的:
NSRange boldedRange = NSMakeRange(2, 4);
What exactly does the 2 stand for and the 4 stand for?
2 和 4 分别代表什么?

It says as:
它说:
NSMakeRange(<#NSUInteger loc#>, <#NSUInteger len#>)
So in your case:
所以在你的情况下:
NSRange boldedRange = NSMakeRange(2, 4);
2 is the starting location.
2 是起始位置。
4 is the character count till what it will use.
4 是直到它将使用的字符数。
Ex. If you use boldedRange
on TYPEWRITER, it will change it to TYPEWRITER
前任。如果您boldedRange
在 TYPEWRITER 上使用,它将更改为 TY PEWRITER
