objective c - How to associate iOS keyboard "go" button with UIButton? -

-

I have a search bar in my SearchViewController , and currently, when they type in If no go button, it only shows back to show me in the keyboard, a Go button, and I want to call it - I want to connect to (IBAction) button: (ID) sender I have connected the current Next UIButton under the search bar

I enable it And how would it be to add about this way? To make it clear, the search bar and next buttons were created in the storyboard, not programmatic. 

  [textField setReturnKeyType: UIReturnKeyGo];   
 or  
  - (zero) setReturnKey {// use condition here (field not empty) self.searchField.returnKeyType = UIReturnKeyGo; }   
 As a second thing, Ghobs has said that you can find here ...   Prefix: (BOOL) textFieldShouldReturn: (UITextField *) TextField {[TextField Resigns First Responder]; // Dismiss the keyboard // Add the action you want to call here. Yes come back }   
 Source for the above code:

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

C++ Array Type Not Assignable in Copy Constructor -

-
I have a simple class that represents the triangle, which consists of three arrays square triangle {public: double x [3]; Double y [3]; Unsigned four colors [3]; }; I want to create objects in this square on the heap, then pass on those functions which will use the value from the array. Since I am in these items, I need to make a deep copy to make a copy. Triangle (const triangle and obj) {X = new double [3]; Y = new double [3]; Color = new unsigned char [3]; For (int i = 0; i I keep the following error: "Error: array type 'double [3]' is not assignable for each of the three arrays. I am taking the same view as discussion, and I do not know why I am unable to create a new array. The answer is also the same approach. Does anyone have any insights? Looks like I'm really stupid. I'm taking the same approach as discussed in this video. In the video, you can see that he started the array Read on the member-preliminary list and how it is dif...
