Question

UIImagePickerController crash tylko na iOS 7-iPad

Dostaję setki awarii z jednej z moich aplikacji na żywo, odkąd ludzie zaczęli uaktualniać do iOS 7. Czy ktoś jeszcze widział ten problem? Nic nie odtwarza się na moim iPadzie 3 z iOS 7...

Miałem ten sam problem.

Miałem UIImagePickerController wyświetlany wewnątrz UIPopoverController z rozmiarem zdefiniowanym przez UIImagePickerController contentSizeForViewInPopover funkcji.
Aby rozwiązać ten problem zmieniłem Rozmiar {[1] } na UIImagePickerController's preferredContentSize function.

Możesz użyć niestandardowej ramki i załadować popover jak poniżej

[popOver presentPopoverFromRect:CGRectMake(self.view.frame.size.width-50, 50, 10, 10) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];

Wspólnie doszliśmy do wniosku, że jest to błąd w iOS 7 na iPadzie. Występuje przy próbie pokazania UIImagePickerController w UIPopoverControl z UIBarButtonItem po raz pierwszy. Po udzieleniu zgody przez użytkownika na album ze zdjęciami następuje awaria. Wygląda na to, że rozwiązaniem na razie jest poproszenie o pozwolenie na zdjęcia przed otwarciem UIPopoverControl. Oto jak zaimplementowałem moje rozwiązanie:

// Photo Library
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary])
{
    void(^blk)() =  ^() {
        UIImagePickerController* picker = [[UIImagePickerController alloc] init];
        picker.delegate = self;
        picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
        if (NIIsPad()) {
            UIPopoverController* popover = [[UIPopoverController alloc] initWithContentViewController:picker];
            [popover presentPopoverFromBarButtonItem:self.popoverAnchor permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
        } else {
            [self.navigationController presentModalViewController:picker animated:YES];
        }
    };

    // Make sure we have permission, otherwise request it first
    ALAssetsLibrary* assetsLibrary = [[ALAssetsLibrary alloc] init];
    ALAuthorizationStatus authStatus;
    if (IOS_VERSION_GREATER_THAN_OR_EQUAL_TO(@"6.0"))
        authStatus = [ALAssetsLibrary authorizationStatus];
    else
        authStatus = ALAuthorizationStatusAuthorized;

    if (authStatus == ALAuthorizationStatusAuthorized) {
        blk();
    } else if (authStatus == ALAuthorizationStatusDenied || authStatus == ALAuthorizationStatusRestricted) {
        [[UIAlertView alertViewWithTitle:@"Grant photos permission" message:@"Grant permission to your photos. Go to Settings App > Privacy > Photos."] show];
    } else if (authStatus == ALAuthorizationStatusNotDetermined) {
        [assetsLibrary enumerateGroupsWithTypes:ALAssetsGroupAll usingBlock:^(ALAssetsGroup *group, BOOL *stop) {
            // Catch the final iteration, ignore the rest
            if (group == nil)
                dispatch_async(dispatch_get_main_queue(), ^{
                    blk();
                });
            *stop = YES;
        } failureBlock:^(NSError *error) {
            // failure :(
            dispatch_async(dispatch_get_main_queue(), ^{
                [[UIAlertView alertViewWithTitle:@"Grant photos permission" message:@"Grant permission to your photos. Go to Settings App > Privacy > Photos."] show];
            });
        }];
    }
}

Nie zapomnij dodać AssetsLibrary.ramy do twojego projekt.
