is it right way in obj-c programming

i wonder if the way i programm is right way or not. can you help me?

@interface ViewController : UIViewController
{
    UILabel *messageLabel;
}
@end

when i declare new object in .h and create in .m i have to use @property (nonatomic, retain) UILabel *messageLabel? i saw few listings where when object are created by code @property doesn't exist and few where does exist and i'm confused.

is it correct when i don't use @property (in example for UILabel, UIImageView, UIButton) when i create objects by code?

Your code is correct. @property is used globally throughout your app, rather than being specific to your UIViewController. If you are only planning on referring or changing the label/other component define it within the { } otherwise @property should be used

@property is a key word useful to create setter/getter methods automatically for that field. If you don't need to access your label from outside your view controller you won't need to use @property and your code is fine.
