ios - how to add two integer values in objective-c -


मैंने निम्न कोड लिखा है 

  NSString * a = @ "TextField1.text" ; NSInteger b = [एक पूर्णांक वैल्यू]; NSString * p = @ "TextField2.text"; NSInteger q = [p पूर्णांक वैल्यू]; _TextLable.text = [NSString stringWithFormat: @ "% d", b + q];   
 इसे बी और क्यू जोड़ना हमेशा नतीजे 0 में  _TextLable.text    
 
 
  NSString * a = @" TextField1.text ";  आपको निम्न सामग्री के साथ एक  NSString  देगा:  
  TextField1.text   
 यह निश्चित रूप से आपके लिए क्या नहीं है। समस्या यह है कि पूर्णांक को परिवर्तित करने में विफल रहता है, और यही कारण है कि  NSInteger  0 है। और 0 * 2 के बाद से 0, आपको परिणाम के रूप में 0 मिलता है।  
 यदि आप पहले से ही  TextField1  और  TextField2  लिंक किए गए UITextFields के रूप में है, फिर निम्न का उपयोग करें:  
  NSString * a = TextField1.text; NSInteger b = [एक पूर्णांक वैल्यू]; NSString * p = TextField2.text; NSInteger q = [p पूर्णांक वैल्यू]; _TextLable.text = [NSString stringWithFormat: @ "% d", b + q];   
 मैं सामान्यतः उद्देश्य सी या प्रोग्रामिंग पर एक किताब पढ़ने की सिफारिश करता हूं, क्योंकि ऐसा लगता है कि आपको बुनियादी समझ की कमी है।

c - Performance of System() -

After the function in C, for the system (), it affects the hardware counters, so how do you order that The example displayed for the example you are trying to view lets the IM use the display API (PAPI) and the program is a precompiled matrix multiplication application. PAPI_start_counters (); System ("./matmul"); PAPI_read_counters (); // Print the values ​​PAPI_stop_counters (); I'm clearly missing a bit, but I'm trying to figure out what it is possible to say, counter receiving a program im running Is through use. With my tests I will get wild numbers like below, they are clearly wrong, just want to find out why total bicycle =========== 140733358872510 instructions complete =========== 4203968 Floating Point Instructions =========== Floating Point Operations =========== 4,196,867 Weight ======= ==== 140733358872804 store ======= ==== 4204037 branches taken =========== 15774436 System () Normally it is a very slow function, on Linux, it is ...

python - how we can use ajax() in views.py in django? -

I have a little code here. Could you please tell me what this code really does? please. Here in the AJAX call: $ .ajax ({url: "{% url} upload_document '%}", type: "POST", data : {Csrfmiddletoken: document.getElementsByName ('csrfmiddletoken') [0] Price, Title: document.getElementById ('title'). Value, // document: document: document.getElementById ('document'),}, datatype: "Jason", success: function (feedback) {if (feedback == "true") {// success} other {// attachment errors}}}); How AJAX works in the Django and how we can see the AJAX request. Here is the idea of ​​my thoughts def upload_document (requested): Print request. POTT print request FILES if request.is_ajax (): If request.method == 'POST': form = UploadForm (request.POST, request.FILES, user = request.user) if form.is_valid (): Form.save () return HTTPPCS (SimpleJason Dumps ('True'), Mime Type = 'App / Jason') Other:...

c++ - How to define methods in a base class that only work in derived classes? -

The title is slightly ambiguous, so I will say an example of what I want to achieve: Class ValuePtr {Public: Operator Canned void * () {return glm :: value_ptr (* this); // value ptr will not work on this class // (works only on glm type)}}; Square mat4x4: public glm :: mat4x4, public valuePtr {// ... but will work here}; Square Vec3: Public glm :: vec3, Public ValuePtr {// ... and here. } Is such a thing possible? glm :: value_ptr works only on glm type like glm :: mat4x4 , glm: : Vec3 , etc. The above seen method works if I implement it directly into derivative classes, but they should all be defined as operator construct * zero * in the same way. I should behave like a special behavior: define it in the general base class, whereas definition only works in derived classes. Thank you for the answer, I use this solution: template & lt; Class T & gt; Class ValuePtr: Public T {Public: Operator Constant * () {return glm :: value_ptr (* this); }}; Class ...
