Answer 1

You can use NSDate Formatter to get the offset from UTC:
NSDateFormatter *dates = [[NSDateFormatter alloc]init];
[dates setDateFormat:#"Z"];
NSLog(#"%#", [dates stringFromDate:[NSDate date]]);
This will log: +0530 (+5:30)
If you want it in your specific format you can simply do:
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc]init];
[dateFormatter setDateFormat:#"Z"];
NSString *offetString = [dateFormatter stringFromDate:[NSDate date]];
NSString *formattedString = [NSString stringWithFormat:#"UTC%#:%#",[offetString substringWithRange:NSMakeRange(0, 3)],[offetString substringWithRange:NSMakeRange([offetString length] - 2, 2)]];

Answer 2

NSDateFormatter *df = [[NSDateFormatter alloc]init];
df.timeZone = [NSTimeZone localTimeZone];
df.dateFormat = #"Z";
NSString *localTimeZoneOffset = [df stringFromDate:[NSDate date]];
NSLog(#"%#",localTimeZoneOffset);
You will get output like,
+0530 for UTC+5:30.
Update : (As asked in comment)
Try below code for your desired format,
NSDateFormatter *df = [[NSDateFormatter alloc]init];
df.timeZone = [NSTimeZone localTimeZone];
df.dateFormat = #"Z";
NSString *localTimeZoneOffset = [df stringFromDate:[NSDate date]];
NSLog(#"%#",localTimeZoneOffset);
NSString *one = [localTimeZoneOffset substringToIndex:1];
NSString *two = [localTimeZoneOffset substringWithRange:NSMakeRange(1, 2)];
NSString *three = [localTimeZoneOffset substringWithRange:NSMakeRange(3, 2)];
NSString *result = [NSString stringWithFormat:#"utc%#%#:%#",one,two,three];
NSLog(#"result : %#",result);
