在iOS10中设置相机闪光灯不起作用-SettingcameraflashnotworkinginiOS10

Cannot set the camera flash properly for iOS versions 10 and above (this is working correctly in iOS 9). It always defaults to UIImagePickerControllerCameraFlashModeAuto.

无法在iOS 10及更高版本中正确设置相机闪光灯（这在iOS 9中正常工作）。它总是默认为UIImagePickerControllerCameraFlashModeAuto。

Here's my code:

这是我的代码：

UIImagePickerController *picker = [[UIImagePickerController alloc] init];
[picker setAllowsEditing:NO];
[picker setDelegate:self];
[picker setSourceType:UIImagePickerControllerSourceTypeCamera];
[picker setCameraFlashMode:UIImagePickerControllerCameraFlashModeOn];
[picker setCameraOverlayView:overlayView];
[self presentViewController:picker animated:YES completion:Nil];

1 个解决方案

[self presentViewController:picker animated:YES completion:nil];

[self presentViewController:picker animated:YES completion:^{
    //For iOS 10 and higher versions so it can set the proper flashmode
    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 10) {
       [picker setCameraFlashMode:UIImagePickerControllerCameraFlashModeOn];
    }
}];
