Getting index of a character in NSString with offset & using substring in Objective-C
- (NSRange)rangeOfString:(NSString *)aString options:(NSStringCompareOptions)mask range:(NSRange)aRangeFor the options use: NSBackwardsSearch
NSRange range = [myString rangeOfString:@" " options:NSBackwardsSearch range:NSMakeRange(0, 11)];Example:
NSString *myString=[NSString stringWithFormat:@"This is my lovely string"];NSRange range = [myString rangeOfString:@" " options:NSBackwardsSearch range:NSMakeRange(0, 11)];NSLog(@"range.location: %lu", range.location);NSString *substring = [myString substringFromIndex:range.location+1];NSLog(@"substring: '%@'", substring);NSLog output:
range.location: 10substring: 'lovely string'Of course there should be error checking that range.location does not equal NSNotFound
