Use the following method:

+ (NSNumber *)numberWithInt:(int)value

For example:

NSNumber *object = [NSNumber numberWithInt:1];

Alternatively, you can use NSUInteger instead of an NSNumber:

NSUInteger myint = 1;    //declare integer "myint" and set to 1
myint++;                 //increment myint

Note that when declaring a NSUInteger, you do not put a * after the type since it is not an object, but rather a typedef that describes a unsigned integer.

As bbum noted below, since NSUInteger is not an object, it cannot be used in places where an object is required (dictionaries, etc.), so this may or may not be a solution to your problem depending on context.

int myInt = 10;
NSNumber * myNumber = [ NSNumber numberWithInt: myInt ];

See the NSNumber documentation:
