以编程方式触发抖动事件iOS [英] Programmatically trigger shake event iOS

问题描述

我已经尝试过以下操作，但是它一直在崩溃...

  +（void）shake {
 NSLog（@TEST）; 
 
 UIMotionEventProxy * m = [[NSClassFromString（@UIMotionEvent）alloc] _init]; 
 
 m-> _subtype = UIEventSubtypeMotionShake; 
 m-> _shakeState = 1; 
 
 [[[UIApplication sharedApplication] keyWindow] motionBegan：UIEventSubtypeMotionShake withEvent：m]; 
 [[[UIApplication sharedApplication] keyWindow] motionEnded：UIEventSubtypeMotionShake withEvent：m]; 
} 
  

苹果在$ code下的模拟器中做什么硬件> ; Shake Gesture ？

解决方案

更改UIMotionEventProxy类（添加两个setter方法） 。我简单地添加了两个方法 setShakeState 和 _setSubtype ，如下所示。

   - （void）setShakeState：（int）fp8 {
 _shakeState = fp8; 
} 
  - （void）_setSubtype：（int）fp8 {
 _subtype = fp8; 
} 
  

然后我将代码更改为以下...

  UIMotionEventProxy * m = [[NSClassFromString（@UIMotionEvent）alloc] _init]; 
 
 [m setShakeState：1]; 
 [m _setSubtype：UIEventSubtypeMotionShake]; 
 
 [[UIApplication sharedApplication] sendEvent：m]; 
 [[[UIApplication sharedApplication] keyWindow] motionBegan：UIEventSubtypeMotionShake withEvent：m]; 
 [[[UIApplication sharedApplication] keyWindow] motionEnded：UIEventSubtypeMotionShake withEvent：m]; 
  

似乎为模拟器和物理设备完美无缺地工作。 这里是可以下载的主要和头文件，如果有人想看到完整的UIMotionEventProxy文件。

How can I programmatically trigger the shake event in iOS?

I've tried the following but it keeps crashing...

+ (void)shake {
    NSLog(@"TEST");

    UIMotionEventProxy *m = [[NSClassFromString(@"UIMotionEvent") alloc] _init];

    m->_subtype = UIEventSubtypeMotionShake;
    m->_shakeState = 1;

    [[[UIApplication sharedApplication] keyWindow] motionBegan:UIEventSubtypeMotionShake withEvent:m];
    [[[UIApplication sharedApplication] keyWindow] motionEnded:UIEventSubtypeMotionShake withEvent:m];
}

What does apple do in the simulator under Hardware > Shake Gesture?

解决方案

Changing the UIMotionEventProxy class (adding two setter methods) seemed to do the trick. I simply added two methods setShakeState and _setSubtype, shown below.

-(void)setShakeState:(int)fp8 {
    _shakeState = fp8;
}
-(void)_setSubtype:(int)fp8 {
    _subtype = fp8;
}

I then changed my code to the following...

UIMotionEventProxy *m = [[NSClassFromString(@"UIMotionEvent") alloc] _init];

[m setShakeState:1];
[m _setSubtype:UIEventSubtypeMotionShake];

[[UIApplication sharedApplication] sendEvent:m];
[[[UIApplication sharedApplication] keyWindow] motionBegan:UIEventSubtypeMotionShake withEvent:m];
[[[UIApplication sharedApplication] keyWindow] motionEnded:UIEventSubtypeMotionShake withEvent:m];

Seems to be working flawlessly for both simulator and physical device. Here are main and header files available for download if anyone wants to see the full UIMotionEventProxy files.
