Use Private API for hiding status bar text. The Apple Product images (https://developer.apple.com/app-store/marketing/guidelines/#images) provide a generic status bar with full cell signal, 9:41 time, and full battery. I used this code to hide the status bar and took screenshots with the simulator. Then I placed the screenshots into the product …

MEAppDelegate.m

#import "MEAppDelegate.h"

@interface UIStatusBar
@property(retain) UIColor * foregroundColor;
@end

@implementation MEAppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    UIStatusBar *statusBar = [[UIApplication sharedApplication] valueForKey:@"_statusBar"];
    statusBar.foregroundColor = [UIColor clearColor];
    return YES;
}

@end
