iOS 自定义相册页面和系统照相机的调用，

Question

这里根据需要，我的相册页面是仿照系统相册进行的自定义，
这里我的问题是，
第一次调用相册页面选取图像，获得图像，没有问题，之后再跳到照相机页面，拍摄图片，此时也进行获得头像，也是可以的，
但是这样调用完之后，我想要再次调用之前自定义的相册页面，选取图像，进行图像的获得时，程序崩溃，

崩溃信息：

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIImage valueForProperty:]: unrecognized selector sent to instance 0x147b2210'

感觉是报野指针的错误，但是这里的一系列操作，我都没有进行内存的释放，因为我的项目里面用的是ARC，所以在这里我不知道为什么会报这个错误，

我的代码如下，

// 从相册获取图片
    - (void) localPhoto {

    if ([UtilityFunc isPhotoLibraryAvailable])
    {
        TAMultiImagePickerController *picker = [[TAMultiImagePickerController alloc] init];
        picker.delegate = self;
        if (_imagePickerArray != nil) {
            picker.selectedAssets = _imagePickerArray;
        }
        [self presentViewController:picker animated:YES completion:nil];
    }
}

+ (BOOL) isPhotoLibraryAvailable{
    return [UIImagePickerController isSourceTypeAvailable:
            UIImagePickerControllerSourceTypePhotoLibrary];
}

// 完成自定义相册里的图片选取的回调
- (void)multiImagePickerController:(TAMultiImagePickerController *)picker didFinishPickingImages:(NSArray *)imagesArray
{
    if (self.popover != nil)
        [self.popover dismissPopoverAnimated:YES];
    else
        [picker.presentingViewController dismissViewControllerAnimated:YES completion:nil];
//    NSArray *tempArray = [NSMutableArray arrayWithArray:imagesArray];

    NSMutableArray *tempArray = [NSMutableArray array];

    for (ALAsset *alsset in imagesArray) {
        UIImage *image = [self fullResolutionImageFromALAsset:alsset];
        [tempArray addObject:image];
    }

    _imagePickerArray = tempArray;
    [self createImagePickerScrollView];

    NSMutableArray *array = [NSMutableArray array];
    for (UIImage *image in _imagePickerArray) {
        NSData* data = UIImageJPEGRepresentation(image, 1.0);
        [array addObject:data];
    }

    [_dataDict setObject:array forKey:@"imageArray"];
//    _departure.imageArray = array;
}

// 拍照
- (void) takePhoto {

    if ([UtilityFunc isCameraAvailable] && [UtilityFunc doesCameraSupportTakingPhotos]) {
        UIImagePickerController *controller = [[UIImagePickerController alloc] init];
        controller.sourceType = UIImagePickerControllerSourceTypeCamera;
        if ([UtilityFunc isFrontCameraAvailable]) {
            controller.cameraDevice = UIImagePickerControllerCameraDeviceFront;
        }
        controller.navigationBar.backgroundColor = [UIColor navBarColor];
        NSMutableArray *mediaTypes = [[NSMutableArray alloc] init];
        [mediaTypes addObject:(__bridge NSString *)kUTTypeImage];
        controller.mediaTypes = mediaTypes;
        controller.delegate = self;
        [self presentViewController:controller
                           animated:YES
                         completion:^(void){
                         }];
    }
}

// 完成拍照后的回调

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

    UIImage *portraitImg = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
    portraitImg = [portraitImg imageByScalingToMaxSize];
    ImageCropperViewController *imgEditorVC = [[ImageCropperViewController alloc] initWithImage:portraitImg cropFrame:CGRectMake(0, 100.0f, self.view.frame.size.width, self.view.frame.size.width) limitScaleRatio:3.0];
    imgEditorVC.delegate = self;
    [picker pushViewController:imgEditorVC animated:YES];
}

- (void)imageCropper:(ImageCropperViewController *)cropperViewController didFinished:(UIImage *)editedImage {

    [_imagePickerArray addObject:editedImage];
    [self createImagePickerScrollView];
