How do I convert NSInteger to NSString datatype?

Question

How does one convert NSInteger to the NSString datatype?

I tried the following, where month is an NSInteger:

  NSString *inStr = [NSString stringWithFormat:@"%d", [month intValue]];

Answer 1

NSIntegers are not objects, you cast them to long, in order to match the current 64-bit architectures' definition:

NSString *inStr = [NSString stringWithFormat: @"%ld", (long)month];

Answer 2

Obj-C way =):

NSString *inStr = [@(month) stringValue];

Answer 3

Modern Objective-C

An NSInteger has the method stringValue that can be used even with a literal

NSString *integerAsString1 = [@12 stringValue];

NSInteger number = 13;
NSString *integerAsString2 = [@(number) stringValue];

Very simple. Isn't it?

Swift

var integerAsString = String(integer)
