IOS: Cannot get correct screen size

I tried to display some SKNodes and I used the width and height of screen to set their positions in order to make them compatible with different screen sizes.

SKNode* obstacle = [SKSpriteNode spriteNodeWithColor:[SKColor greenColor] size:obstacleSize];
obstacle.position = CGPointMake(80, self.size.height * 0.38);
obstacle.physicsBody = [SKPhysicsBody bodyWithRectangleOfSize:obstacle.frame.size];

But nodes' positions still change when I run the program with a different screen size (fine in 3.5 inch but wrong in 4-inch). And I found that self.size.height is not the actual height of the screen.

Does anyone know how to solve this problem?

[UIScreen mainScreen].bounds.size should return the correct CGSize vector of the width and height. However, if you are in landscape, the values will be reversed, then what'd you would expect from portrait.

[UIScreen mainScreen].bounds.size returns a CGSize with the width and height of the screen. See the UIScreen Apple documentation.
