关闭UIImagePickerController时注意到红条

问题描述

我正在使用UIImagePickerController记录，编辑视频并将其保存到文件.在关闭UIImagePickerController时，状态栏闪烁红色并消失.我想避免这种情况.我一直注意到，iOS8.1，iOS8，iOS7.1等的出现频率在降低.

I am using the UIImagePickerController to record, edit and save Video to file. While dismissing the UIImagePickerController the status bar blinks red and disappears. I want to avoid this. I have been noticing this in decreasing frequency from iOS8.1, iOS8, iOS7.1 ,etc

- (void) cameraClicked{
    self.recordState=KRERecordStateRecording;
    UIImagePickerController *pickerController = [[UIImagePickerController alloc] init];
    pickerController.delegate  = self;
    pickerController.sourceType = UIImagePickerControllerSourceTypeCamera;

    if(self.mediaType==MediaTypePhoto){
        pickerController.mediaTypes = [[NSArray alloc] initWithObjects: (NSString *) kUTTypeImage, nil];

    }else if(self.mediaType==MediaTypeVideo){
        pickerController.mediaTypes = [[NSArray alloc] initWithObjects: (NSString *) kUTTypeMovie, nil];
        pickerController.allowsEditing = YES;
        pickerController.videoMaximumDuration=30.0f;
    }
    [self presentViewController:pickerController animated:YES completion:nil];
}

- (void)imagePickerController:(UIImagePickerController *)picker
        didFinishPickingImage:(UIImage *)image
                  editingInfo:(NSDictionary *)editingInfo{

}
- (void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingMediaWithInfo:(NSDictionary *)info{

    [picker dismissViewControllerAnimated:YES completion:nil];

    NSString *mediaType = [info objectForKey: UIImagePickerControllerMediaType];
    if (CFStringCompare ((CFStringRef) mediaType, kUTTypeImage, 0)
        == kCFCompareEqualTo) {
        self.selectedMedia = [[NSArray alloc] initWithObjects:[info objectForKey:UIImagePickerControllerOriginalImage], nil];
        [self saveMedia];
    }else if(CFStringCompare ((CFStringRef) mediaType, kUTTypeMovie, 0)
             == kCFCompareEqualTo){
        videoURL= [info objectForKey:UIImagePickerControllerMediaURL];
        [self saveMedia];
    }
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker{
    [picker dismissViewControllerAnimated:YES completion:nil];
}

WORKAROUND !!

WORKAROUND!!

我无法获得该问题的实际解决方案，但确实找到了解决方法.关闭AudioSession

I couldn't get an actual solution for the problem but did find a work around.Switch off the AudioSession

[[AVAudioSession sharedInstance] setActive:NO error:nil] 

在关闭UIImagePickerController之前似乎是唯一的选择.经验证可以满足我的需求.但这可能不是理想的解决方案

before dismissing the UIImagePickerController seems to be the only option. This verified to work for my needs. But may not be an ideal solution
