Same xib for iPhone4 and iPhone5 possible?

问题:

Is there any way I can design my classes for both iPhone4 and iPhone5 using the same xib?

回答1:

Yes, you can use the same XIB to design for iPhone 4 and iPhone 5 by using Auto-Layout.

Build an app using iOS 6 as the Base SDK and use the Auto Layout feature to make screens that can scale for all type of screens. You'll need Xcode 4.5 to do this.

Get started with Auto Layout here:

Add a image named [e-mail]. That will identify your app as one that supports iPhone 5 metrics. And also you need to do auto sizing of your views properly.

回答3:

Well short answer to you question is YES;

Long is :- If you user XCode 4.5 and build app that is universal the NIB files and Classes would work perfectly for Iphone 4 and Iphone 5; Understand for you it important to know the version of SDK of these mobiles not the mobile version them self.

Another thing is that iphone 5 size is little bigger then iphone 4 so you need to design accordingly.. please read my answer at Iphone 5 screen resolution issue for better understanding.

Also look at the How to develop or migrate apps for iPhone 5 screen resolution? answer for more clarification on universal app desing.

回答4:

yes it is possible,

just remove the side angle and make object free by enabling inner arrow. so it will automatically resize according to screen.

• but remember one thing that this will only work when you provide all default or any other splash screen.

回答5:

If you want to make some small changes(e.g images position and sizes, scroll view content insets..), you can use codes to differentiate between iPhone 5 and iPhone 4/4s, and implement your codes inside the if/else statement.

You can use auto layout feature provided by apple. Please refer to apple document for this:- https://developer.apple.com/library/ios/documentation/UserExperience/Conceptual/AutolayoutPG/Introduction/Introduction.html

Please define below line and check condition based on device.

#define IS_IPHONE_5 ( fabs( ( double )[ [ UIScreen mainScreen ] bounds ].size.height - ( double )568 ) < DBL_EPSILON )

if (IS_IPHONE_5) {

        btnBookmark.frame=CGRectMake(0, 460, 100, 70);
        btnBookmark.frame=CGRectMake(150, 460, 100, 70);


    }else{
        btnBookmark.frame=CGRectMake(0, 360, 100, 70);
        btnBookmark.frame=CGRectMake(150, 360, 100, 70);


    }

Use AutoAutoresizing so that u can make app compatible with both iOS 5 and iOS 6. This is easy if your layout is having minimum dependancies. And this is possible for fixing issues with components like UIToolBar. Buttons in iPhone 5.
