Multiple XIB error: Could not load NIB in bundle

Question

I want to load different .xib for iPhone 4 and 5.

I have three files FirstViewController.h , FirstViewController.m and FirstViewController.xib I have added one more empty .xib file for iPhone 5 and named it FirstViewController4Inch.xib .

Here is my code snippet:

- (id)initWithCoder:(NSCoder *)aDecoder
{
    self = [super initWithCoder:aDecoder];
    if (self) {
        if ([[UIScreen mainScreen] bounds].size.height == 480)
        {
            self = [super initWithNibName:@"FirstViewController.xib" bundle:nil];
        }
        else
        {
            self = [super initWithNibName:@"FirstViewController4Inch.xib" bundle:nil];
        }
        return self;
    }
    return self;
}

When I run my app on both 3.5 and in 4 it gives the error:

Error:Could not load NIB in bundle:

Answer 1

I think this would work:

- (id)init
{
    if ([[UIScreen mainScreen] bounds].size.height == 480)
    {
        self = [super initWithNibName:@"FirstViewController" bundle:nil];
    }
    else
    {
        self = [super initWithNibName:@"FirstViewController4Inch" bundle:nil];
    }
    return self;
}

as long as you create it programmatically using:

myVC = [[MyViewController alloc] init];

Answer 2

省略.xib部分。

self = [super initWithNibName:@"FirstViewController" bundle:nil];

Answer 3

Remove this line

self = [super initWithCoder:aDecoder];

Also make sure that both .xibs have your class as file owner.

Answer 4

Change your method like this :

- (id)init
{
    self = (IS_IPHONE5() ? [super initWithNibName:@"FirstViewController4Inch" bundle:nil] : [super initWithNibName:@"FirstViewController" bundle:nil]);

    if (self)
    {
        // Custom initialization
    }
    return self;
}

and use the macro IS_IPHONE5()

#define IS_IPHONE5()    ((UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) && [UIScreen mainScreen].bounds.size.height == 568)

Answer 5

use this:

- (id)initForCustomScreen
{
    NSString *nibName = ([[UIScreen mainScreen] bounds].size.height == 480 ? @"FirstViewController" : @"FirstViewController4Inch");

    self = [super initWithNibName:nibName bundle:nil];
    if (self) {

        // initialisation code
    }

    return self;
}

Answer 6

The solution is a combination of Nickos and Maggie. Here is the merged solution which uses the View Controller Class name to provide the Nib name:

- (id)initWithCoder:(NSCoder *)aDecoder
{
    if (self)
    {
        NSString* nibName = NSStringFromClass([self class]);
        if ([[UIScreen mainScreen] bounds].size.height == 480)
        {
            self = [super initWithNibName:nibName bundle:nil];
        }
        else 
        {
            self = [super initWithNibName:[nibName stringByAppendingString:@"4inch"] bundle:nil];
        }
        return self;
    }
    return self;
}
