ObjC Sourcecode Example

    //** Sample Datatypes **
    int myInt = 30;
    double myDouble = 3.14;
    BOOL myBool = NO;
    float myFloat = 1.123456f;
 
    //******************** Initializing NSNumber Objects *************************
 
    //** NSNumbers need to be released, if you`re not working with ARC! **
 
    NSNumber *myBoolNumber = [[NSNumber alloc]initWithBool:myBool];
    NSNumber *myIntNumber = [[NSNumber alloc]initWithInt:myInt];
    NSNumber *myDoubleNumber = [[NSNumber alloc]initWithDouble:myDouble];
    NSNumber *myFloatNumber = [[NSNumber alloc]initWithFloat:myFloat];
 
    NSLog(@"myBoolNumber: %@", myBoolNumber);
    NSLog(@"myIntNumber: %@", myIntNumber);
    NSLog(@"myDoubleNumber: %@", myDoubleNumber);
    NSLog(@"myFloatNumber:%@", myFloatNumber);
