I have NSString with couple strings like this that the 465544664646 is change between them :
data-context-item-title="465544664646"
How i parse the 465544664646 string to a Array ?
Edit
NSRegularExpression* myRegex = [[NSRegularExpression alloc] initWithPattern:#"(?i)(data-context-item-title=\")(.+?)(\")" options:0 error:nil];
[myRegex enumerateMatchesInString:responseString options:0 range:NSMakeRange(0, [responseString length]) usingBlock:^(NSTextCheckingResult *match, NSMatchingFlags flags, BOOL *stop) {
NSRange range = [match rangeAtIndex:1];
NSString *string =[responseString substringWithRange:range];
NSLog(string);
}];

Try this one:
NSString *yourString=#"data-context-item-title=\"465544664646\" data-context-item-title=\"1212121212\"";
NSMutableArray *substrings = [NSMutableArray new];
NSScanner *scanner = [NSScanner scannerWithString:yourString];
[scanner scanUpToString:#"\"" intoString:nil];
while(![scanner isAtEnd]) {
NSString *tempString;
[scanner scanString:#"\"" intoString:nil];
if([scanner scanUpToString:#" " intoString:&tempString]) {
[substrings addObject:tempString];
}
[scanner scanUpToString:#"\"" intoString:nil];
}
//NSLog(#"->%#",substrings); //substrings contains all numbers as string.
for (NSString *str in substrings) {
NSLog(#"->%ld",[str integerValue]); //converted each number to integer value, if you want to store as NSNumber now you can store each of them in array
}

Something like this?
-(NSString *)stringFromOriginalString:(NSString *)origin betweenStartString: (NSString*)start andEndString:(NSString*)end {
NSRange startRange = [origin rangeOfString:start];
if (startRange.location != NSNotFound) {
NSRange targetRange;
targetRange.location = startRange.location + startRange.length;
targetRange.length = [origin length] - targetRange.location;
NSRange endRange = [origin rangeOfString:end options:0 range:targetRange];
if (endRange.location != NSNotFound) {
targetRange.length = endRange.location - targetRange.location;
return [origin substringWithRange:targetRange];
}
}
return nil;
}

You can use
- (NSArray *)componentsSeparatedByString:(NSString *)separator
method like
NSArray *components = [#"data-context-item-title="465544664646" componentsSeparatedByString:#"\""];
Now you should got the string at 2. index
[components objectAtIndex:1]
Now you can create array from that string using the method here
NSString to NSArray
