iPhone在加载时呈现空白视图

我正在使用通用应用(iPhone和iPad)。我有一个应该打开设置视图的按钮,我有两个单独的XIB文件,一个用于iPad,另一个用于iPhone。我有以下代码:

settingsView* sv=[[settingsView alloc]initWithNibName:@"settingsView" bundle:nil];
settingsView* isv=[[settingsView alloc]initWithNibName:@"settingsView_iPad" bundle:nil];

if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {

    [self presentModalViewController:sv animated:YES];
    NSLog(@"I am an iPhone");

}

if([[UIDevice currentDevice] userInterfaceIdiom]== UIUserInterfaceIdiomPad) {

    [self presentModalViewController:isv animated:YES];
    NSLog(@"I am an iPad");
}

此代码只显示设备上的黑屏,状态栏位于顶部。我不知道为什么。任何帮助将不胜感激。

此致

解决此问题的最佳方法是,在Class.xib文件中拖放两个UIViewController。创建两个@property(非原子,保留)ClassAVC和@property(非原子,保留)ClassBVC,建立连接到空UIViewController你只需要删除到class.xib文件,并将NIB名称更改为settingsView和settingsView_ipad nib文件名。然后尝试

    [self presentModalViewController:ClassAVC animated:YES];
    [self presentModalViewController:ClassBVC animated:YES];

以及

    [self.navigationController pushViewController:ClassAVC animated:YES];
    [self.navigationController pushViewController:ClassBVC animated:YES];
