Is it possible to display the control center in button click? ios

Question

I'm having a problem in displaying the control center in iOS, i've been searching for some docs regarding on this issue but couldn't find an answer. Is there a way, to make the control center appear by clicking a UIButton?.

You can apply constraints programatically to a specific UI element (link to iOS developer doc)

Sample code of this eg.:

// Center horizontally
[self.view addConstraint:[NSLayoutConstraint constraintWithItem:viewToBeCentered
                                                      attribute:NSLayoutAttributeCenterX
                                                      relatedBy:NSLayoutRelationEqual
                                                         toItem:self.view
                                                      attribute:NSLayoutAttributeCenterX
                                                     multiplier:1.0
                                                       constant:0.0]];

// Center vertically
[self.view addConstraint:[NSLayoutConstraint constraintWithItem:viewToBeCentered
                                                      attribute:NSLayoutAttributeCenterY
                                                      relatedBy:NSLayoutRelationEqual
                                                         toItem:self.view
                                                      attribute:NSLayoutAttributeCenterY
                                                     multiplier:1.0
                                                       constant:0.0]];

You can include this code into your button's action code.

Hope this helps to achieve the desired effect!
