ios - Hides UINavigationController's UIToolbar when pop -

-

मेरे पास दो दृश्य नियंत्रक ए और बी है।

ए में एक तालिका दृश्य है और जब उपयोगकर्ता एक पंक्ति पर नल, B धकेल दिया जाता है।

B में UIToolbar self.navigationController.toolbarHidden = NO; और समस्या यह है कि जब मैं B से A से पॉप करता हूं : उपकरण पट्टी ए पर भी बनी हुई है और मुझे पता नहीं है कि कैसे निकालना है।

यह हो रहा है क्योंकि आप टूलबार को छिपाना नहीं करते जब आप B से A viewController तक पॉप करते हैं बी viewController 

  #pragma mark - #ViewVillDisappear के तरीके में - निम्न कोड का उपयोग करें / देखें: (शून्य) दृश्यविशेषताएं: (BOOL) एनिमेटेड {[सुपर दृश्यवहीआकार: एनिमेटेड]; Self.navigationController.toolbarHidden = हाँ; }   
 तो, जब भी आप  B  से  A  viewController तक पॉप अप करते हैं, तब भी अपना टूलबार छुपाएं।  ए  viewController।

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ...

Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
