MoonString is basically a NSString category with a bunch of nifty methods that I think should have been in the NSString class in the first place.
MoonString's methods:
- (NSString*)stringBetweenString:(NSString*)start andString:(NSString*)end;
- (NSMutableArray*)stringsBetweenString:(NSString*)start andString:(NSString*)end;
- (NSArray*)splitString:(NSString*)string seperator:(NSString *)seperator;
- (NSString*)compileStrings:(NSArray*)chunks seperator:(NSString*)seperator;
- (NSUInteger)countWords;
- (NSString*)stripNewlines;
- (NSString*)removeSpacesFromString;
- (NSString *)trimWhitespaceFromEnds;
- (NSString *)inverseCapitalisationString;
- (NSString*)removeSubstring:(NSString*)substring;
- (NSUInteger)occurrencesOfString:(NSString *)needle;
- (BOOL)containsString: (NSString*)substring range:(NSRange*)range;
- (BOOL)containsString:(NSString *)substring;
To use them, just import them with
#import "NSString+MoonString.h"
May I note that I haven't written most of these methods. The ones I haven't written, I have collected from snippets on StackOverflow or somewhere else.
