Question

我有这段代码：

-(void)add
{
    if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]==NO)
    {

        NSLog(@"No Camera");


    }
    else
    {
        cameraUI=[[UIImagePickerController alloc] init];
        cameraUI.delegate=self;
        cameraUI.allowsEditing=YES;
        cameraUI.sourceType=UIImagePickerControllerSourceTypeCamera;
        [self presentViewController:cameraUI animated:YES completion:nil];

    }

}

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    self.photo=[info objectForKey:UIImagePickerControllerOriginalImage];

}

现在我需要在另一个名为SaveViewController的视图中传递照片，而不在此字段中使用segue：

@property（弱，非原子）IBOutlet UIImageView * imageField;

Answer 1

使用

 SaveViewController *saveView = [[SaveViewController alloc]init];

 saveView.imageField.image = self.photo;

//push saveView

Answer 2

您可以创建所需视图控制器的对象（在本例中为SaveViewController）并设置属性。然后，当您需要调用该视图时，您必须使用您创建的同一对象来呈现该视图。例如，

self.photo = [info objectForKey:UIImagePickerControllerOriginalImage]; SaveViewController *svc = [[SaveViewController alloc] init]; svc.imageField.image = self.photo; [self.navigationController presentViewController:svc animated:YES completion:nil];

Answer 3

您可以在标头文件中创建UIImage *passImg。在ImagePickerDelegate方法中分配

self.passImg = [info objectForKey:UIImagePickerControllerOriginalImage];

然后当你推动时：

SaveViewController *savedVC = [self.storyboard instantiateViewControllerWithIdentifier:@"SaveViewController"];
savedVC.imageField.image = passImg;
[self.navigationController pushViewController:savedVC animated:YES];

如果popViewController使用 NSNotificationCenter 。
