Display screen for iOS6 and iOS7 in simulator is different - ios

Question

My application i will give deployment target 6.1 so in 7.0 display and 6.1 display screen different so how to adjust the size in both 6.1 and 7.0

Answer 1

Main UI difference in iOS 6 and iOS 7 is that status bar is included inside the viewcontroller in iOS 7. it means your view controller is 20 px greater than iOS6. you have to adjust your items.
First design your items according to iOS 6 which is better way and you must have a lot of practice of doing that, now set Δy to 20 for every item.
Or design your items according to iOS 7 and set Δy to -20

Answer 2

use ios7.0 and later and then handle the secrren size using autolayout

Answer 3

Add this code in your AppDelegate.m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
//Whatever your code goes here
if(kDeviceiPad){
//adding status bar for IOS7 ipad
if (IS_IOS7) {
UIView *addStatusBar = [[UIView alloc] init];
addStatusBar.frame = CGRectMake(0, 0, 1024, 20);
addStatusBar.backgroundColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:1]; //change this to match your navigation bar
[self.window.rootViewController.view addSubview:addStatusBar];
}
}
else{
//adding status bar for IOS7 iphone
if (IS_IOS7) {
UIView *addStatusBar = [[UIView alloc] init];
addStatusBar.frame = CGRectMake(0, 0, 320, 20);
addStatusBar.backgroundColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:1]; //You can give your own color pattern
[self.window.rootViewController.view addSubview:addStatusBar];
}
return YES;
}
