ios - 如何在另一个 View 中打开图像？

Question

我正在尝试制作一个具有 2 个 View 的 iOS 应用程序。第一个 View 包含两个按钮:相机和库。当我选择“库”时，我访问相机胶卷。我想选择一张照片并在另一个 View 中打开它。到目前为止我写了这个函数

-(IBAction) getPhoto:(id) sender {
    UIImagePickerController * picker = [[UIImagePickerController alloc] init];
    picker.delegate = self;

    if((UIButton *) sender == choosePhotoBtn) {
        picker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
    } else {
        picker.sourceType = UIImagePickerControllerSourceTypeCamera;
    }

    [self presentViewController:picker animated:YES completion:nil];

}   


- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    [picker dismissViewControllerAnimated:YES completion: Nil];
    imageView.image = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
}

在同一 View 中打开我的图像。如何在其他 View 中打开此图像？

Answer 1

你可以做类似的事情

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    UIImage *image = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
    [picker dismissViewControllerAnimated:YES completion:^{
        YourSeconViewController *svc = [[UIViewController alloc] initWithNibName:@"YourSeconViewController" bundle:nil];
        svc.imageView.Image = image;
        [self presentViewController:svc animated:YES completion:nil];
    }];
}
