ios - UITextView selectAll method not working as expected -

-

I am making iOS 8 App with Xcode 6.0.1 for my iPhone 5 (which is iOS 8.0.2 ). I want to make it so much that when a user clicks on my UITextView , all the text is selected so that they start typing and erase it easily (but I do not want to Text is automatically erased because users want to keep it or attach it) To do this, I have the following code: 

  - (zero) textViewDidBeginEditing: (UITextView *) TextView {if ([TextView hasText]) {NSLog (@ "before selectedRange:% d ", TextView.selectedRange.length); [Select TextViewAll: Self]; NSLog (@ selected range after:% d ", textView.selectedRange.length); }}   
 When this method is called, then I expect the console output (i.e.  selectedRange  length is similar to the number of characters in the code> text view < / Code> text). However, nothing appears as selected in  UITextView  and it is not selected (i.e. no selection menu pops up).  
  I have seen many questions like this on the Internet, but did not work for me for any solution  (and some of them did not work for a bug without providing any solution In the form it is written) To do something other than to change this ID  self  (like  zero ) did not help, and neither calling it to  [Selection TextView: Self] As a person suggested I also tried this code:  
  - (zero) textViewDidBeginEditing: (UITextView *) TextView {if ([ TextView hasText]) {UITextRange * border = [TextView textRangeFromPosition: textView.beginningOfDocument toPosition: textView.endOfDocument]; [TextView set selected selected selected text: Category];   
  "itemprop =" text "> 
 This solution also works and does not require subclassification  UITextView , just on your representative Enter this function:  
 Objective 3 -  
  - (bool) textViewShouldBeginEditing: (UITextView *) TextView {dispatch_async (dispatch_get_main_queue (), ^ {[TextView selectAll: Zero] ;} Return;}   
 Swift 3 -  
  function textViewDidBeginEditing (_VideoView) (Zero)}}

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...
