Question

I have two storyboard with size for iphone 5 and size for iphone 4. All this device have 6 IOS. So i have my code for check version of IOS ...

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{


    // 1
    UIStoryboard * mainStoryboard = nil ;
    if ( SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO ( @ "6.0" ) ) {
        mainStoryboard = [ UIStoryboard storyboardWithName : @ "iPhones6.0" bundle : nil ] ;
    } else {
        mainStoryboard = [ UIStoryboard storyboardWithName : @ "iPhones3-5" bundle : nil ] ;
    }

    // 2
    self.window = [ [ UIWindow alloc ] initWithFrame : [ [ UIScreen mainScreen ] bounds ] ] ;
    self.window.rootViewController = [ mainStoryboard instantiateInitialViewController ] ;
    [ self.window makeKeyAndVisible ] ;




    return YES;
}

If i have iphone 4 with 6 iOS and iphone also 6 IOS, i have big size display and for iPhone but for iphone 4 not work. SO how can i know what device i used, for make checking for model.

Was it helpful?

Solution 2

You should not select your storyboard according to iOS version but select it according to the screen size. Like this

CGRect screenBounds = [[UIScreen mainScreen] bounds];
    if (screenBounds.size.height == 568) {
        //device is iphone 5
        //add storyboard that have large screen (320*568)
    } else {
          //device is iphone 4
          //add story board that have small screen (320*480)

    }

Because it does matter which iOS is it when we displaying our screen it depend on iPhone Screen Size.

You can also differentiate iPhone and iPad using this code

if ([[UIDevice currentDevice] userInterfaceIdiom] ==UIUserInterfaceIdiomPhone)
    {
      //device is iPhone
    }
else
    {
      //device is iPad
    }

And for differentiate which iOS version in your device you can use this code,

float currentVersion = 6.0;

if ([[[UIDevice currentDevice] systemVersion] floatValue] >= currentVersion)
{
    //device have iOS 6 or above
}else{
   //device have iOS 5.1 or belove
}

Happy coding ^_^

You are not checking correctly in the first place.

You could've used the UIScreen to get the size of the screen and determine which device is used. Also if you are developing for iOS 6 then you only need 1 Storyboard and you can use Autolayout option for the controllers and create NSLayoutContrains from the interface builder.

THis should be a lot easier than having 2 stroyboards for each iPhone.

There is no need to have 2 storyboards for 4inch devices (iPhone 5) and 3.5inch devices (iPhone 4S and lower).

The iPad requires a separate storyboard as the screen is far larger, but for an extra 88 pixels in height on iPhone 5, theres not really a lot more you can fit on as extra.

AutoLayout from iOS6 solves this problem, even the old Autoresizing properties solves this.

If you have an extra view (or any UI element) just for the iPhone 5, then simply detect the screen height as suggested by Dilip and if it's not iPhone 5 then hide the UI element using myElement.hidden = YES;.

CGRect screenBounds = [[UIScreen mainScreen] bounds];
if (screenBounds.size.height <= 480) {
    myElement.hidden = YES;
}

In Storyboard view of Xcode theres a button on the iPhone storyboard which switches between 3.5 inch and 4 inch so you can adjust components positions to suit the device as shown below on the left.
