以编程方式更改UIViewController视图NIB的最佳方法 [英] Best way to change UIViewController view NIB programmatically

问题描述

我的iPad应用程序包含不同的NIB和视图。
每个视图都有两个NIB，一个用于potrait方向，一个用于landscape，所以我正在寻找一种方法来以编程方式为给定的UIViewController切换NIB。

I have this iPad application with different NIBs and views. Each view has two NIBs, one for potrait orientation and one for landscape, so i'm searching for a method to programmatically switch NIB for a given UIViewController .

现在我有这个函数，我在每个控制器的willRotateToInterfaceOrientation方法中使用：

Right now i have this function that i'm using in the willRotateToInterfaceOrientation method of each controller :

void UIHandleRotation( UIViewController *controller, NSString *nibName, UIInterfaceOrientation orientation, BOOL transform ){
    double angle = 0.0;

    if( orientation == UIInterfaceOrientationPortrait ) {
        angle = PI * 2 /* 360° */;
    } 
    else if( orientation == UIInterfaceOrientationLandscapeLeft ){
        angle   = PI + PI/2 /* 270 ° */;
        // Each landscape nib is [nib-name]L
        nibName = [NSString stringWithFormat:@"%@L", nibName];
    }    

    [[NSBundle mainBundle] loadNibNamed:nibName owner:controller options:nil];
    if( transform ) {
        controller.view.transform = CGAffineTransformMakeRotation( angle );
    } 
}

但它给了我奇怪的行为（ui控制位置搞砸了，出口没有在界面构建器中关联，等等。

But it's giving me strange behaviour (ui controls position messed, the outlets are not associated as in interface builder, and so forth).

我做错了什么或者只是有更好的方法来实现它？
谢谢

Am i doing something wrong or there's just a better way to implement this ? Thanks

注意：我没有使用导航控制器，因此我无法使用此解决方案最简单的方法来支持多个方向？如何在应用程序处于横向时加载自定义NIB？

NOTE: I'm not using a navigation controller, so i can't use this solution Easiest way to support multiple orientations? How do I load a custom NIB when the application is in Landscape?

推荐答案

您不应该切换笔尖，你应该切换控制器。

You shouldn't switch nibs, you should switch controllers.
