我正在开发一个使用tabbar系统的项目. tabbar项之一是JobPostingViewController.我将它嵌入UINavigationController中.在这个视图控制器中有一个名为add new job的UIButton.我实现了pushviewcontroller去CreateJobPostViewController.在那里我需要添加UI
ImagePickerController来选择图像.当我点击完成按钮或从库中选择一个图像时,它会关闭到JobPostingViewController.但它应该去CreateJobPostViewController.
任何人请帮助我.提前致谢.

JobPostingViewController中的代码
@H_301_8@@IBAction func openCreateJob(sender: AnyObject) { let vc = self.storyboard?.instantiateViewControllerWithIdentifier("CreateJobPostViewController") as! CreateJobPostViewController self.navigationController?.pushViewController(vc,animated: true) }CreateJobPostViewController中的代码
@H_301_8@@IBAction func addImages(sender: AnyObject) { imagePicker.allowsEditing = false imagePicker.sourceType = .PhotoLibrary presentViewController(imagePicker,animated: true,completion: nil) } func imagePickerController(picker: UIImagePickerController,didFinishPickingMediaWithInfo info: [String : AnyObject]) { picker.dismissViewControllerAnimated(true,completion: nil) } func imagePickerControllerDidCancel(picker: UIImagePickerController) { picker.dismissViewControllerAnimated(true,completion: nil) }解决方法
将Picker添加为子视图
尝试将imagepicker作为子视图添加到您的CreateJobPostViewController中,然后将其从代理中的父项中删除
@H_301_8@@IBAction func openCreateJob(sender: AnyObject) { var picker: UIImagePickerController = UIImagePickerController() picker.delegate = self picker.allowsEditing = false picker.sourceType = .PhotoLibrary self.addChildViewController(picker) picker.didMoveToParentViewController(self) self.view!.addSubview(picker.view!) }然后
@H_301_8@func imagePickerControllerDidCancel(picker: UIImagePickerController) { picker.view!.removeFromSuperview() picker.removeFromParentViewController() }用于呈现
通过currentcontext显示选择器,例如编辑取消选择,
在演示之前使用picker.modalPresentationStyle = .overCurrentContext //
它
