Does anyone know why? Thank you in advance for any help.
ViewController.m:

AppDelegate *appDelegate = [[UIApplication sharedApplication] delegate];
device = appDelegate.deviceType;
NSLog(@"The device platform is: %@", device);
if ([[device substringToIndex:8] caseInsensitiveCompare: @"iPhone 5"] == NSOrderedSame) {
[background sizeThatFits:CGSizeMake(320, 504)];
}
else {
[background sizeThatFits:CGSizeMake(320, 416)];

In this way, the background is adjusted to the appropriate size of the view controller view, not only has nothing to do with the device, but also regardless of whether the view controller is embedded as another container controller in the future (For example, what if you put the view in the navigation controller and tab bar controller, your own custom container controller, etc.). Also, don’t assume the status bar or other graphics The size of the element. Let iOS simply do all this for you:
background.frame = self.view.bounds;

If you can, you can avoid explicit device name references in the code in the bottom line, and avoid hard-coded coordinates. Using hard-coded dimensions in your code will only make your application more vulnerable and vulnerable to new devices , the new version of iOS, embedding view controllers into other container controllers and other issues, and restricting code reuse opportunities.
I am trying to adjust the background static state for iPhone5 users The size of the UI ImageView (from the Nib file). Unfortunately, the following code does not seem to have any effect on the size of the background view.

Some thoughts:

>If you want to set the frame programmatically, I recommend setting the background.frame property based on the view boundary of the view controller instead of hard-coding the size of the image view. In this way, the background is adjusted to the view controller The appropriate size of the view is not only related to the design It is irrelevant, and regardless of whether the view controller is embedded as a child view controller of another container controller in the future. (For example, if you put the view in the navigation controller and the tab bar controller, your own custom In container controllers, etc., what to do). Also, don’t assume the size of the status bar or other graphic elements. Let iOS simply do all this for you:
background. frame = self.view.bounds;
> Or better yet, if you have added the background image view to the NIB itself, please set an auto-adjustment mask and do not change the frame programmatically. If You turn off autolayout, just set the automatic adjustment properties of the image view, as shown below:
If you can, you can avoid clear device name references in the code in the bottom line, and avoid using hard-coded coordinates. The use of hard-coded dimensions in the code will only make your application more fragile, vulnerable to issues such as new devices, new versions of iOS, embedding view controllers into other container controllers, and limit code reuse opportunities.
