Question

i m 试图通过<代码> UIImage from one UIView in TabBarController1 to another UIView in NavigationController in Tab BarController2。在观点1中,我试图:

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

    UploadModifyViewController *view2 = [self.storyboard instantiateViewControllerWithIdentifier:@"modify"];
    UITabBarController *navBar = [self.storyboard instantiateViewControllerWithIdentifier:@"navBar"];
    view2.imageView.image = image;                //<-----
    [self dismissModalViewControllerAnimated:NO];
    [self presentModalViewController:navBar animated:YES];
}

换文后,见2为导航管理员,导航主计长为塔巴主计长。廉价工作,因为这些工作可能与工匠。

Posted this question here too, but still no solution. In this forum i posted a screenshot for better understanding from where to where i try to pass the image.

Answer 1

It probably doesn t work because the imageView outlet is still nil at the time you are accessing it. A view controller doesn t load its view unless it has to, and only when it loads its view from the NIB/storyboard will it connect the outlets.

您应宣布<代码>UIImage中的财产,UploadModificationViewController, 你可以在此地点将图像贴上。然后,在<代码>上上载ModificationViewController sviewDidLoad,将财产内容贴在图像上。
