I have used this method for detecting the width and height of screen. But its showing the width as 768 and height as 1024 in portrait and landscape also.

```
CGRect screenBounds = [[UIScreen mainScreen] bounds]; 

float widthfloat=  screenBounds.size.width;
float heightfloat= screenBounds.size.height;

NSLog(@"  width float %f",widthfloat);
NSLog(@"height float %f",heightfloat);

NSLog(@"width view %f \n height view %f", self.view.bounds.size.width, self.view.bounds.size.height);
NSLog(@"width %f \n height %f", screenBounds.size.width, screenBounds.size.height);

float wvalue  = [[UIScreen mainScreen] bounds].size.width;

float hvalue =  [[UIScreen mainScreen] bounds].size.height;

NSLog(@"  wvalue %f",wvalue);
NSLog(@"hvalue %f",hvalue);

CGFloat width1 = [UIScreen mainScreen].bounds.size.width;
CGFloat height1 = [UIScreen mainScreen].bounds.size.height;

NSLog(@"width1 %f",width1);
NSLog(@"height1 %f",height1);

CGFloat screenScale = [[UIScreen mainScreen] scale];

CGRect screenBounds1 = [[UIScreen mainScreen] bounds];

CGSize screenSize = CGSizeMake(screenBounds1.size.width * screenScale, screenBounds1.size.height * screenScale); if (screenSize.height==1136.000000)

NSLog(@"abcd1 %f",screenBounds1.size.width);
NSLog(@"abcd2 %f",screenBounds1.size.height);
NSLog(@"efgh1 %f",screenSize.width);
NSLog(@"efgh2 %f",screenSize.height);

```
