I think you can capture the layer of self.view because it the root view

if ([[UIScreen mainScreen] respondsToSelector:@selector(scale)]) {
    //Retina display
    UIGraphicsBeginImageContextWithOptions(self.view.bounds.size, NO, [UIScreen mainScreen].scale);
} else {
    UIGraphicsBeginImageContext(self.view.bounds.size);
}
[self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *finalImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

Have fun!

Try this:

UIGraphicsBeginImageContext(/*CGRECT*/);     
[self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *screenImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

Here in CGRect pass your rect which you want to take screenshot.

Hope it helps you..

Set your

CGRect screenshotFrame = CGRectMake(0, 0, 320, 436);
// 480(screen height) - 44(toolbar height) = 436
