我有iPhone应用程序覆盖相机与自定义视图.
我有一个按钮来切换相机闪光模式,这是代码
我有一个按钮来切换相机闪光模式,这是代码
switch ([self.imagePickerController cameraFlashMode]) {
case UIImagePickerControllerCameraFlashModeAuto:
[self.imagePickerController setCameraFlashMode:UIImagePickerControllerCameraFlashModeOn];
return @"On";
break;
case UIImagePickerControllerCameraFlashModeOn:
[self.imagePickerController setCameraFlashMode:UIImagePickerControllerCameraFlashModeOff];
return @"Off";
break;
case UIImagePickerControllerCameraFlashModeOff:
[self.imagePickerController setCameraFlashMode:UIImagePickerControllerCameraFlashModeAuto];
return @"Auto";
break;
default:
break;
}
这是我的问题：在iOS 7.0x上工作得很好,但在iOS 7.1中,cameraFlashMode属性返回UIImagePickerControllerCameraFlashModeAuto,而不管其真实状态如何.
闪光模式确实发生变化,但是我没有指示.
任何线索？
谢谢
解决方法
我这样解决了：
@property (nonatomic) NSInteger flashMode;
if (_flashMode == UIImagePickerControllerCameraFlashModeAuto)
{
_flashMode = UIImagePickerControllerCameraFlashModeOff;
}
else if (_flashMode == UIImagePickerControllerCameraFlashModeOff)
{
_flashMode = UIImagePickerControllerCameraFlashModeOn;
}
else if (_flashMode == UIImagePickerControllerCameraFlashModeOn)
{
_flashMode = UIImagePickerControllerCameraFlashModeAuto;
}
_cameraPicker.cameraFlashMode = (UIImagePickerControllerCameraFlashMode)_flashMode;
