我们可以为一个View Controller使用两个不同的Xib吗？

Question

I have two different xib's. Let say we have created one xib for iPhone & another for iPad. I wanted to know how can we pass iPad xib's outlet referencing properties to the viewcontroller properties, already been set by the iPhone Xib.

I know one way of implementation is by using Size class. But i want to know how can we implement from the above approach.

Answer 1

Set two Xib and set name like that

1.ViewController_ipad.XIB for ipad

2.ViewController.XIB for iphone

When you run your Project in iPhone while open iphone xib. When you run your Project in iPad while open ipad xib.

and set logic like that

 if ( UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad ) { ViewController *tempView = [[ViewController alloc] initWithNibName:@"ViewController_ipad" bundle:nil]; [self.navigationController pushViewController:tempView animated:YES]; } else { ViewController *tempView = [[ViewController alloc] initWithNibName:@"ViewController" bundle:nil]; [self.navigationController pushViewController:tempView animated:YES]; } 

Answer 2

Yes we can use two different xib's for same viewController. Following is one example where we want different xib for iPhone and iPad.

NSString* nibName = @"ProgressViewController";

if( UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad )
    nibName = @"ProgressViewController_iPad";

ProgressViewController * view = [[ProgressViewController alloc] initWithNibName:nibName bundle:nil];
[self.navigationController pushViewController:view animated:YES]; // Optional if you have used navigation controller at root

Answer 3

Yes. You can use two xibs in single view controller. Using this you can switch to other nib. (Xib) NSString* nib = @"ViewController";

if( UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad )
    nib = @"ViewController_iPad";

ViewController * view = [[ViewController alloc] initWithNibName:nib bundle:nil];
[self.navigationController pushViewController:view animated:YES];

You can bind same functions with other nib objects but you have to bind every object with different names

Like :- your label in ViewController apple So you can put label name in ViewController_iPad apple_iPad.

It means you can use same function in both nibs but you have to use diff object bindings for both.
