为 NSString 的整个长度生成 NSRange 的快捷方式？

Question

Is there a short way to say "entire string" rather than typing out:

NSMakeRange(0, myString.length)]

It seems silly that the longest part of this kind of code is the least important (because I usually want to search/replace within entire string)…

[myString replaceOccurrencesOfString:@"replace_me"
                          withString:replacementString
                             options:NSCaseInsensitiveSearch
                               range:NSMakeRange(0, myString.length)];

Answer 1

Function? Category method?

- (NSRange)fullRange
{
    return (NSRange){0, [self length]};
}

---

[myString replaceOccurrencesOfString:@"replace_me"
                          withString:replacementString
                             options:NSCaseInsensitiveSearch
                               range:[myString fullRange]];

Answer 2

Not that I know of. But you could easily add an NSString category:

@interface NSString (MyRangeExtensions)
- (NSRange)fullRange
@end

@implementation NSString (MyRangeExtensions)
- (NSRange)fullRange {
  return (NSRange){0, self.length};
}

Answer 3

Swift 4+ , useful for NSRegularExpression and NSAttributedString

extension String {
    var nsRange : NSRange {
        return NSRange(self.startIndex..., in: self)
    }

    func range(from nsRange: NSRange) -> Range<String.Index>? {
        return Range(nsRange, in: self)
    }
}

Answer 4

Swift

NSMakeRange(0, str.length)

or as an extension :

extension NSString {
    func fullrange() -> NSRange {
        return NSMakeRange(0, self.length)
    }
}

Answer 5

这不是更短，而是......哦，好吧

NSRange range = [str rangeOfString:str];

Answer 6

Swift 2:

extension String {
    var fullRange:Range<String.Index> { return startIndex..<endIndex }
}

as in

let swiftRange = "abc".fullRange

or

let nsRange = "abc".fullRange.toRange
