iOS：如何实现“摇动设备”事件？

发布于 2024-11-25 14:16:37 字数 283 浏览 0 评论 0原文

我想为我的应用程序添加“摇动设备”事件 - 即，当用户摇动设备时会发生一些事情。我尝试实施：

-(void) motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event {
    if (event.subtype == UIEventSubtypeMotionShake) {
        //something happens
    }
}

它似乎不起作用......
有谁知道我应该使用哪种方法？

I want to a "Shake Device" event to my app - i.e., when the user shakes the device something happens.
I tried implementing:

-(void) motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event {
    if (event.subtype == UIEventSubtypeMotionShake) {
        //something happens
    }
}

It doesn't seem to work.......
Does anyone knows which method I should use?

尝试使用下面的代码，它对我来说效果很好。

- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event
{
    if ( event.subtype == UIEventSubtypeMotionShake )
       {
          //your code
       }

    if ( [super respondsToSelector:@selector(motionEnded:withEvent:)] )
                [super motionEnded:motion withEvent:event];
}
- (BOOL)canBecomeFirstResponder
{
    return YES;
}

Try using the below code, it worked fine for me.

- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event
{
    if ( event.subtype == UIEventSubtypeMotionShake )
       {
          //your code
       }

    if ( [super respondsToSelector:@selector(motionEnded:withEvent:)] )
                [super motionEnded:motion withEvent:event];
}
- (BOOL)canBecomeFirstResponder
{
    return YES;
}

可能来不及回答，但在您的 viewDidLoad 中您需要包含。

[self becomeFirstResponder];

尝试一下。

Might be to late to answer but in your viewDidLoad you need to include.

[self becomeFirstResponder];

Give that a try.

除了 Taylor 的解决方案之外，还要确保您的 AppDelegate.m 中包含此解决方案。

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    application.applicationSupportsShakeToEdit = YES;
    return YES;
}

In addition to Taylor's solution, also make sure that your AppDelegate.m has this in it.

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    application.applicationSupportsShakeToEdit = YES;
    return YES;
}
