viewcontroller - Presenting a view controller programmatically in swift -

-

hi trying convert following objective c code swift navigate 1 view controller view controller when button clicked. appreciated

this taken apple's programming guide

  - (void)add:(id)sender {  // create root view controller navigation controller  // new view controller configures cancel , done button  // navigation bar.    recipeaddviewcontroller *addcontroller = [[recipeaddviewcontroller alloc]                    init];   // configure recipeaddviewcontroller. in case, reports  // changes custom delegate object.    addcontroller.delegate = self;   // create navigation controller , present it.   uinavigationcontroller *navigationcontroller = [[uinavigationcontroller alloc]                          initwithrootviewcontroller:addcontroller];   [self presentviewcontroller:navigationcontroller animated:yes completion: nil];   }

my code indicated below, not sure how implement in navigation controller, in storyboard mainsectionviewcontroller embedded navigation controller

    func sectionbtnclicked (sender: uibutton!) {           let sectioncontroller = self.storyboard?.instantiateviewcontrollerwithidentifier("mainsectionsvc") mainsectionviewcontroller           let navcontroller = uinavigationcontroler. ///not sure comes here, appreciated           self.presentviewcontroller(navcontroller, animated: true, completion: nil)   }

do want present navcontroller modally?

if yes, answer

self.presentviewcontroller(navcontroller, animated: true, completion: nil)

"self" current view controller present navcontroller

and put this,

class viewcontroller: uiviewcontroller {             override func viewdidload() {         super.viewdidload()          var thebutton = uibutton()          // add event button         thebutton.addtarget(self, action: "buttontouchinside:", forcontrolevents: .touchupinside)          self.view.addsubview(thebutton)     }      func buttontouchinside(sender:uibutton!)     {         // when button touched, we're going present view controller          // 1. wrap view controller within navigation controller          let navcontroller = uinavigationcontroller(rootviewcontroller: yourviewcontroller)          // 2. present navigation controller          self.presentviewcontroller(navcontroller, animated: true, completion: nil)     }  }

but,

if want navigate between viewcontroller in navigationcontroller, can use

self.navigationcontroller.pushviewcontroller(viewcontrollertopush, animated: true)
