摇动以模式方式打开视图

发布于 2024-08-30 03:21:52 字数 446 浏览 10 评论 0原文

我的“摇动”工作正常（使用motionEnded），基于Apple的GLPaint代码。当用户摇动设备（运行 3.0 及更高版本）时，我想使用presentModalViewController 以模态方式打开视图控制器。

在我的 appdelegate 中，我收到通知（根据 GLPaint 示例代码）：

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(shakeToOpenHiddenScreen) name:@"shake" object:nil];

在我的 shakeToOpenHiddenScreen 中，我只想以模态方式打开视图“x”，但我不认为我的 appdelegate 会响应 PresentModalViewController。

有办法解决这个问题吗？

I have my 'shake' working fine (using motionEnded), based off of Apple's GLPaint code. When the user shakes the device (running 3.0 and up) I want to open a view controller modally using presentModalViewController.

In my appdelegate I have the notification (as per the GLPaint sample code):

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(shakeToOpenHiddenScreen) name:@"shake" object:nil];

In my shakeToOpenHiddenScreen I just want to open view 'x' modally but I don't think that my appdelegate will respond to presentModalViewController.

Is there a way around this?

要使用presentModalViewController，您必须从UIViewController类或子类中使用它：

例如：
//RootViewController.m
[self.navigationController PresentModalViewController:loginRegView 动画:YES];

您可以通过在应用程序委托中定义导航控制器

//yourApp_comAppDelegate.h
UINavigationController *nav;
...
@property(nonatomic,retain) UINavigationController *nav;

并合成它来

@syntetize nav;

解决此问题：要使用presentModalViewController，您必须从 UIViewController 类或子类中使用它：

//RootViewController.m
[self.navigationController presentModalViewController:loginRegView animated:YES];

您可以通过在应用程序委托中定义导航控制器来解决此问题你的应用程序委托：

//yourApp_comAppDelegate.h
UINavigationController *nav;
...
@property(nonatomic,retain) UINavigationController *nav;

合成它

//yourApp_comAppDelegate.m
@synthesize nav;

，现在你可以使用该方法：

//yourApp_comAppDelegate.m
[nav presentModalViewController:yourView animated:YES];

但是，首先你必须将它分配到某个地方，我将在 RootViewController 中进行它

//RootViewController.m
- (void)viewDidLoad {
    [super viewDidLoad];
app = (yourApp_comAppDelegate *) [[UIApplication sharedApplication] delegate];
    app.nav = self.navigationController
}

应该可以工作，让我知道:)

To use presentModalViewController you have to use it from a UIViewController class, or subclass:

For example:
//RootViewController.m
[self.navigationController presentModalViewController:loginRegView animated:YES];

You can way around this problem by defining a navigation controller into your app delegate:

//yourApp_comAppDelegate.h
UINavigationController *nav;
...
@property(nonatomic,retain) UINavigationController *nav;

and synthesize it

@syntetize nav;

//yourApp_comAppDelegate.m
@synthesize nav;

and now you can use the method:

//yourApp_comAppDelegate.m
[nav presentModalViewController:yourView animated:YES];

but, first you have to assign it somewhere, i will do it in the RootViewController

//RootViewController.m
- (void)viewDidLoad {
    [super viewDidLoad];
app = (yourApp_comAppDelegate *) [[UIApplication sharedApplication] delegate];
    app.nav = self.navigationController
}

It should work, let me know :)
