iOS-将iP​​hone Build转换为iPad

Question

I have a application that I built that was to be build as an iPhone-only application.

Now, I am told that the application has to be made universal now. I will have to make it iPad compatible too (in portrait-only mode). I have been looking for my options right now as the XIBs in this project are heavily loaded with objects so programatically assigning co-ordinates will be a pain.

I am looking for the best, and the quickest approach I should take to make this iPhone app into iPad-compatible app as well.

PS: There is no mainwindow.xib file as the application was built with XCode 4.3 which doesn't create the MainWindow.xib file.

Thank you in advance.

EDIT: I have made duplicate XIBs for iPad for all the XIBs. Now, I am trying to use the naming convention which tells me to change the filename suffix to MyiPadXIB~ipad.xib and when the app is run on iPad, it will automatically take that XIB. This doesn't seem to be happening.

When I open the application in iPad, only a small window appears (the window that appears when iPhone-only app is run on an iPad).

Any solution to this?

Answer 1

I followed a very easy approach where I would just create duplicate XIBs of all the XIBs by doing Build settings > target (iPhone)> right click and choose duplicate.

I would then change the name of the duplicate xibs in this format: "iPhone XIB name"~ipad.xib.

The system would then automatically pick up the XIB according to the device used.

Answer 2

From what I know (there may be a quicker/better approach that i dont know of)

You would create seperate xib files for the ipad

when you init your view controller you check to see what device you are on like so

if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
        self.serverSettingsViewController = [[ServerSettingsViewController alloc] initWithNibName:@"ServerSettingsViewController_iPhone" bundle:nil];
        self.motionJpegViewController = [[MotionJpegViewController alloc] initWithNibName:@"MotionJpegViewController_iPhone" bundle:nil];
    } else {
        self.serverSettingsViewController = [[ServerSettingsViewController alloc] initWithNibName:@"ServerSettingsViewController_iPad" bundle:nil];
        self.motionJpegViewController = [[MotionJpegViewController alloc] initWithNibName:@"MotionJpegViewController_iPad" bundle:nil];
    }

And load you iphone or ipad xib file (FYI make sure the xib views are large enough for the ipad)
