iphone - 使用标签栏和导航 Controller ， View 被解除到错误的 View

Question

好的，这是我的基本设置的图片

现在这可能不是设置所有内容的最佳方式，但我已经尽我所能，我必须获得我想要的效果。现在我的问题起源于 View 1，但仅当您这样做时才会发生:从菜单开始，单击 View 2,3 或 4 转到该 View ，然后现在在该屏幕上使用标签栏按钮转到 View 1，您将单击获取图片按钮，其 View Controller 中包含以下代码以显示图像选择器。现在问题来了，如果你此时返回，它会将你带到你从菜单中单击的 tabbarview，无论它是 2、3 还是 4。如果你从菜单中单击 View 1，它会返回正常

- (void)viewDidLoad
{
    [super viewDidLoad];

    // Do any additional setup after loading the view, typically from a nib.
    self.selectedPhotos = [NSMutableArray array];

    __block AGViewController *blockSelf = self;

    ipc = [[AGImagePickerController alloc] initWithDelegate:self];
    ipc.didFailBlock = ^(NSError *error) {
        NSLog(@"Fail. Error: %@", error);

        if (error == nil) {
            [blockSelf.selectedPhotos removeAllObjects];
            NSLog(@"User has cancelled.");

          [blockSelf dismissViewControllerAnimated:YES completion:nil];


        } else {

            // We need to wait for the view controller to appear first.
            double delayInSeconds = 0.5;
            dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, delayInSeconds * NSEC_PER_SEC);
            dispatch_after(popTime, dispatch_get_main_queue(), ^(void){
                [blockSelf dismissViewControllerAnimated:YES completion:nil];
            });
        }

        [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleDefault animated:YES];

    };
    ipc.didFinishBlock = ^(NSArray *info) {
        [blockSelf.selectedPhotos setArray:info];

        NSLog(@"Info: %@", info);

        //add all selected photos to the claim

        [blockSelf setClaimPhotos:info];

        [blockSelf dismissViewControllerAnimated:YES completion:nil];

        [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleDefault animated:YES];
    };

}

- (void)openAction:(id)sender
{    
    // Show saved photos on top
    ipc.shouldShowSavedPhotosOnTop = NO;
    ipc.shouldChangeStatusBarStyle = YES;
    ipc.selection = self.selectedPhotos;
    ipc.maximumNumberOfPhotosToBeSelected = 5;

    // Custom toolbar items
    AGIPCToolbarItem *selectAll = [[AGIPCToolbarItem alloc] initWithBarButtonItem:[[UIBarButtonItem alloc] initWithTitle:@"+ Select All" style:UIBarButtonItemStyleBordered target:nil action:nil] andSelectionBlock:^BOOL(NSUInteger index, ALAsset *asset) {
        return YES;
    }];
    AGIPCToolbarItem *flexible = [[AGIPCToolbarItem alloc] initWithBarButtonItem:[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil] andSelectionBlock:nil]; 

    AGIPCToolbarItem *deselectAll = [[AGIPCToolbarItem alloc] initWithBarButtonItem:[[UIBarButtonItem alloc] initWithTitle:@"- Deselect All" style:UIBarButtonItemStyleBordered target:nil action:nil] andSelectionBlock:^BOOL(NSUInteger index, ALAsset *asset) {
        return NO;
    }];  
    ipc.toolbarItemsForManagingTheSelection = @[selectAll, flexible, flexible, deselectAll];

    [self presentViewController:ipc animated:YES completion:nil];
}

(打开 Action 是绑定(bind)在vc上的按钮)

我真的需要这方面的帮助，因为我整个星期都被这个问题困住了，并且一直在尝试所有类型的 dissmiss View Controller 等等。

Answer 1

问题是由于 TabBarController 上的自定义类导致 SelectedIndex 属性出现意外行为。
