Question

1 US Dollar = 3.673 United Arab Emirates Dirham

How to get only value 3.673 from this string?

I tried the following code, but didn’t work.

NSString *a = [[xmlParser array]objectAtIndex:2];
NSRange startRange = [a rangeOfString:@"="];
NSLog(@"%u",startRange.location+1);
NSRange endRange = [a rangeOfString:@" "];
NSLog(@"%u",endRange.location);
NSString *subString = [a substringWithRange:NSMakeRange(startRange.location + 1, endRange.location)];
NSLog(@"%@",subString);

Use this:

 NSArray *aArray = [a componentsSeparatedByString:@" "]; //your string here
 NSString *dollarValue = [aArray objectAtIndex:4]; //get dollar value from array
 NSLog(@"%@",dollarValue);
