ios-如何关闭窗口上的加载UIViewController

Question

I have a question, I want to build popup view like the UIAlertView ,

I create two UIViewController in the storyboard(note: there are not segue),and Root UIViewController will load the UIViewController view popup.

I create two UIViewController to edit the UIView , because I want to use the storybaord to edit my complex UIView in the feature.

Then I put the container view on the RootViewController and there are two button in the container view.(my structure as below:)

When I click the pop up green button(with button name popupGreenBtn ), It can correct addSubview on the UIWindow .

 - (void)viewDidLoad {
[super viewDidLoad];
     NSLog(@"ContainerViewController view didload");

 appDelegate = (AppDelegate*)[[UIApplication sharedApplication]delegate];


 UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:@"Main" bundle: nil];

 secondGreenVC = (SecondGreenViewController*)[mainStoryboard instantiateViewControllerWithIdentifier:@"SecondGreenViewController"];

 thirdRedVC = (ThirdRedViewController*)[mainStoryboard instantiateViewControllerWithIdentifier:@"ThirdRedViewController"];

 }

 - (IBAction)popupGreenBtnAction:(id)sender {

     [appDelegate.window addSubview: secondGreenVC.view];
     [appDelegate.window bringSubviewToFront:secondGreenVC.view];

 }

 - (IBAction)popupRedBtnAction:(id)sender {
     [appDelegate.window addSubview: thirdRedVC.view];
     [appDelegate.window bringSubviewToFront:thirdRedVC.view];

 }

When I click the button , it can correct popup on the window:

But now , When I click the SecondGreenViewController and ThirdRedViewcontroller background view(just transparent dark black), I want to close the popon the view( secondGreenVC.view or thirdRedVC.view ).

I had try to add the code in the SecondGreenViewController class below:

 @implementation SecondGreenViewController

 - (void)viewDidLoad {
     [super viewDidLoad];
     UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapAction:)];
     [_secondBaseView addGestureRecognizer:tap];
 }

 -(void) tapAction:(UITapGestureRecognizer*) recognizer
 {
     [self removeFromParentViewController];
      //    [self dismissViewControllerAnimated:NO completion:nil];
     NSLog(@"tap in SecondGreenViewController");
 }
 @end

There are not effect to close the UIViewController .

How can I close the Popup window(the UIViewController ) when I click the dark black part?

(If you want to more info, please tell me or you can see my this simple project from github https://github.com/dickfalaDeveloper/PopUpViewDemo )

Thank you very much.

Answer 1

  -(void) tapAction:(UITapGestureRecognizer*) recognizer
{
thirdViewcontroller.hidden=YES;
 }

Answer 2

I resolve the problem. But I don't know have any best answer.

My method is in the popupGreenBtnAction actin.

change the code to:

  appDelegate.window.rootViewController.modalPresentationStyle = UIModalPresentationCurrentContext;
  secondGreenVC.modalPresentationStyle = UIModalPresentationCustom;
  [appDelegate.window.rootViewController presentViewController:secondGreenVC animated:NO completion:nil];

Then in the SecondGreenViewController storyboard,

Drag an other UIView do base UIView and set the UIView IBOutlet(now I name with"secondBaseView").

at SecondGreenViewController.m

 - (void)viewDidLoad {
     [super viewDidLoad];
     UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapAction:)];
     [self.secondBaseView addGestureRecognizer:tap];
 }

 -(void) tapAction:(UITapGestureRecognizer*) recognizer
 {
 [self dismissViewControllerAnimated:NO completion:nil];
 }

That is Ok to show the modal and dismiss the modal UIViewController.
