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!
