iphone - 如何在本地/远程通知上闪烁 iphone 的手电筒

Question

我找不到让手电筒闪烁的代码，因为如果有任何通知，它会在 Android 中闪烁。

Answer 1

所有你必须调用这个函数:

/////////////

- (void)torchOnOff: (BOOL) onOff
{

AVCaptureDevice *device = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo];

if ([device hasTorch]) {

    [device lockForConfiguration:nil];

    [device setTorchMode: onOff ? AVCaptureTorchModeOn : AVCaptureTorchModeOff];

    [device unlockForConfiguration];
}

}
