Take the width and height of the device

Question

I am using this code:

CGRect myRect = CGRectMake(self.frame.size.width, self.frame.size.height);

But he gives this error:

- Property "frame" not found on object of type [myViewController]

Anyone have any ideas on how to change the code?

Answer 1

First of all, you have too few arguments for the function CGRectMake. You must determine your origin. In addition, selfyou need to have instead self.view. It looks something like this:

CGRect myRect = CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height);

Answer 2

the presentation frame is executed from inside the code

  CGRect myViewFrame = self.view.frame;

or screen frame if that is what you want (the device says in the question header)

CGRect screenFrame = [[UIScreen mainScreen] bounds];

or it will return the same status bar minus if visible

CGRect actualyScreenFrame = [[UIScreen mainScreen] applicationFrame];

Answer 3

Use

CGRect myRect = CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.heigh);

And if you want to know the screen size of the device, you should use:

[UIScreen mainScreen].bounds
