我的应用程序在备用版本中在 iPad 模拟器上崩溃，崩溃然后运行然后崩溃，等等。

objc[1116]: Class Protocol is implemented in both /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.2.sdk/usr/lib/libobjc.A.dylib and /Users/NGA24iMAC3/Library/Application Support/iPhone Simulator/4.2/Applications/C0FFA7D7-7684-4854-B641-62BD11CFD226/Innovations.app/Innovations. One of the two will be used. Which one is undefined.

但是在 IB 中正确设置了所有插座。请帮助我。提前谢谢。

@Ishu 我认为您在 IB 中的连接有问题。我知道您检查了您的 IB，但您可以再次制作您的 .xib 文件。

我建议清理你的项目。Command+ Shift+K

接下来，打开您的 XIB 文件并验证“文件所有者”的视图出口是否已连接到您的视图。的不连接，它和保存。

重建你的项目。

我在通用应用程序中也遇到了同样的问题。

我做了这样的事情解决了我的问题-

- (id)initWithNibName:(NSString *)n bundle:(NSBundle *)b
{
    return [self init];
}


- (id)init
{



    BOOL iPad = NO;
#ifdef UI_USER_INTERFACE_IDIOM
    iPad = (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad);
#endif


    if (iPad) 
    {
        // iPad specific code here
        NSLog(@"Device is iPad");
        [super initWithNibName:@"ContactUsViewController~ipad" bundle:nil];

    } else 
    {
        // iPhone/iPod specific code here
        NSLog(@"Device is iPhone");
        [super initWithNibName:@"ContactUsViewController" bundle:nil];

    }

    return self;
}

当您添加/推送视图控制器时，只需调用其 init 方法，然后推送视图控制器。

  1. 在 Interface Builder 中打开我们的 iPad xib
  2. 单击文件的所有者
  3. 在检查器中，转到第四个选项卡（身份）
  4. 将充当该 xib 的视图控制器的类的名称写为类标识。
  5. 准备好出发！
