当我使用Xcode版本4.5.2(4G2008a)为通用应用程序5.0及更高版本创建新的“选项卡式应用程序”时,它在6.0模拟器上运行良好,但在5.1或5.0上运行不正常。
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
UIViewController *viewController1;
UIViewController *viewController2;
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
viewController1 = [[FirstViewController alloc] initWithNibName:@"FirstViewController_iPhone" bundle:nil];
viewController2 = [[SecondViewController alloc] initWithNibName:@"SecondViewController_iPhone" bundle:nil];
} else {
viewController1 = [[FirstViewController alloc] initWithNibName:@"FirstViewController_iPad" bundle:nil];
viewController2 = [[SecondViewController alloc] initWithNibName:@"SecondViewController_iPad" bundle:nil];
}
self.tabBarController = [[UITabBarController alloc] init];
**self.tabBarController.viewControllers = @[viewController1, viewController2];**
self.window.rootViewController = self.tabBarController;
[self.window makeKeyAndVisible];
return YES;
}
这是断点捕获的地方 self.tabBarController.viewControllers = @ [viewController1,viewController2];
我对苹果设置没有任何改变。我看过,但也许我在谷歌搜索错误的东西。
答案 0 :(得分:0)
它是因为xib文件中的auto布局属性。转到两个xib文件,在右侧菜单中单击选中视图时顶部的第一个选项卡,然后取消勾选使用自动布局文本框。
希望这有助于。
