incompatible integer to pointer conversion unsigned long

Hello

I have a code to create my own function but it gives me a warning:

- Incompatible integer to pointer conversion assigning to 'SMUserKey *' (aka 'unsigned long *') from 'int'

- Incompatible integer to pointer conversion sending 'SMUserKey' (aka 'unsigned long') to parameter of type 'SMUserKey *' (aka 'unsigned long *')

When I run the app, it works fine, but I dont want the warnings.

This is my .h code:

typedef NSUInteger SMUserKey;

NS_ENUM(SMUserKey) {

SMUsername = 1,

SMFirstName = 2,

SMLastName = 3,

SMFullName = 4,

SMEmail = 5,

};

This is my .m code:

-(void)awakeFromNib {

NSString *result = [SMUsergetValueForKey:SMUsername];

NSLog(@"THE RESULT: %@", result);

}

+ (NSString *)getValueForKey:(SMUserKey*)myUserKey {

NSString *myUserKeyValue = nil;

if ((myUserKey = 1)) {

myUserKeyValue = @"Username";

}

return myUserKeyValue;

}

This is the image showing the warnings:
