How to remove starting 0's in uitextfield text in iphone sdk

Code Snippet:

    NSString *tempStr = self.consumerNumber.text;        

    if ([tempStr hasPrefix:@"0"] && [tempStr length] > 1) {
        tempStr = [tempStr substringFromIndex:1];

        [self.consumerNumbers addObject:tempStr];>           
    }

I tried those things and removing only one zero. how to remove more then one zero

Output :001600240321

Expected result :1600240321

Any help really appreciated
