Question

我一直在努力实施国家恢复和保护。

我没有使用故事板。我必须做错事。

我为每个Nib文件设置了恢复标识符。

我知道状态正在存储，但从未正常恢复。最后一个状态显示半秒，然后返回主视图。我尝试了许多没有运气的事情。请帮忙！

-(BOOL)application:(UIApplication *)application willFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    NSLog(@"will finish");
    return YES;
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
    self.viewController = [[[ViewController alloc] initWithNibName:@"ViewController" bundle:nil] autorelease];

    navigator = [[UINavigationController alloc] initWithRootViewController:self.viewController];
    self.window.rootViewController = navigator;

    [self.window makeKeyAndVisible];
    [navigator release];

    NSLog(@"did finish");
    return YES;
}
// As you can see, I started the process of saving and restoring application state.
// Also, I added the restoration identifier for every class that should be restored.

-(BOOL)application:(UIApplication *)application shouldRestoreApplicationState:(NSCoder *)coder
{
    NSLog(@"restoring");
    return YES;
}
-(BOOL)application:(UIApplication *)application shouldSaveApplicationState:(NSCoder *)coder
{
    return YES;
}
-(void)application:(UIApplication *)application didDecodeRestorableStateWithCoder:(NSCoder *)coder
{
    NSLog(@"restored");
    //navigator = [[UINavigationController alloc] initWithRootViewController:];

    isRestored = YES;
}

Answer 1

您应该在application:willFinishLaunchingWithOptions:中进行控制器初始化，因为在调用application:didFinishLaunchingWithOptions:之前已完成恢复。

检查this answer。

此外，您应该以编程方式将restorationIdentifier分配给所有控制器。

iOS 6保存和恢复没有故事板
