【问题描述】：
我知道已经问过这种类型的问题，但我对其进行了详细的调试，当我关闭此标志时，我得出了这一点
self.picker.showsCameraControls = false
然后自定义闪光灯按钮没有响应，但如果我将标志更改为
self.picker.showsCameraControls = true
然后我的自定义 flash 按钮响应 OK，我检查了所有的代表和标志，但我无法确定错误，无论是在我的代码中还是在 IOS 10 版本中，如果它在我的代码中关于显示相机控制为什么我的自定义闪光灯按钮会改变闪光灯状态并正常工作。 这是我的代码以便更好地理解：
func configureImagePicker(){
self.picker.delegate = self
self.picker.allowsEditing = false
if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.Camera)
{
self.picker.sourceType = UIImagePickerControllerSourceType.Camera
self.picker.mediaTypes = [kUTTypeImage as String]
}
}
func showImagePicker(){
if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.Camera){
self.picker.sourceType = UIImagePickerControllerSourceType.Camera
self.picker.showsCameraControls = false
self.picker.delegateController = self
self.picker.delegate = self
self.picker.mediaTypes = [kUTTypeImage as String]
self.picker.allowsEditing = false
if let cameraOverlay = self.picker.cameraOverlayView {
self.createCamerOverlay(cameraOverlay.frame)
self.picker.cameraOverlayView = self.overlayView
self.presentViewController(self.picker, animated: false, completion: {
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, Int64(Double(0.5)*Double(NSEC_PER_SEC))), dispatch_get_main_queue(), {
if self.picker.cameraDevice == UIImagePickerControllerCameraDevice.Rear && UIImagePickerController.isFlashAvailableForCameraDevice(UIImagePickerControllerCameraDevice.Rear)
{
if Float.init(UIDevice.currentDevice().systemVersion) < 11.0
{
switch(Global.shared.currenFlashOption)
{
case .FlashOff:
self.picker.cameraFlashMode = .Off
let flashImage = UIImage(named: "btn-flash-off")
self.flashButton.setImage(flashImage, forState: UIControlState.Normal)
self.flashButton.setImage(flashImage, forState: UIControlState.Highlighted)
case .FlashAuto:
self.picker.cameraFlashMode = .Auto
let flashImage = UIImage(named: "btn-flash")
self.flashButton.setImage(flashImage, forState: UIControlState.Normal)
self.flashButton.setImage(flashImage, forState: UIControlState.Highlighted)
case .FlashOn:
self.picker.cameraFlashMode = .On
let flashImage = UIImage(named: "btn-flash-on")
self.flashButton.setImage(flashImage, forState: UIControlState.Normal)
self.flashButton.setImage(flashImage, forState: UIControlState.Highlighted)
}
}
else
{
self.picker.cameraFlashMode = UIImagePickerControllerCameraFlashMode.On
}
}
});
});
} else {
print("Camera overlay frame not found. So did not present the controller.")
}
}
else{
let alert = UIAlertView(title: "Error", message: "Camera Not Available", delegate: nil, cancelButtonTitle: "Cancel")
alert.show()
}
}
简而言之，我的自定义 flashmode 按钮在 cameraoverlayview 上不起作用。 如果这个问题没有解决方案，那么请提出任何黑客建议。 谢谢
