ios - Using navigationBarHidden as getter property is not giving error -


में UINavigationController.h हमारे पास घोषित संपत्ति है 

  @ प्रॉपर्टी (नॉनैटोमिक, गेटर = हैन्यूविंगबारहिदद) बुल नेविगेशनबारहार्ड;   
 यह स्पष्ट रूप से कहता है कि इसके प्राप्तकर्ता  हैनविगेशनबारहैड  है लेकिन मुझे नहीं पता कि मैं इसे  नेविगेशनबारहार्ड  / P> <पूर्व>  - (शून्य) दृश्यडिडअपेर: (BOOL) एनिमेटेड {[सुपर व्यूडडपिपर: एनिमेटेड]; Self.navigationController.navigationBarHidden = हाँ; // यहाँ एक त्रुटि फेंक दिया, लेकिन यह BOOL मान संकलित करता है = self.navigationController.navigationBarHidden; }   
 कोई भी विचार क्यों हो रहा है? या मैं इसे गलत तरीके से व्याख्या कर रहा हूं  
 
 संपादित करें  
 मुझे इसके बारे में कुछ संदर्भ  
 पर मिल गया है, लेकिन सेब के refernces की तलाश में।   
 
 
 समस्या यह है कि आप संपत्ति और उसके गेटर्स और सेटर्स को भ्रमित कर रहे हैं।  
 जब आप उपयोग करते हैं:  self.navigationController.navigationBarHidden  आप सीधे संपत्ति का जिक्र कर रहे हैं, जिसका अर्थ है कि कंपाइलर "=" चिह्न की स्थिति के आधार पर प्राप्तकर्ता या सेटर को कॉल करने वाला तरीका देखेंगे।  
 लेकिन जब आप  [self.navigationController navigationBarHidden];  का उपयोग करते हैं, तो आप स्पष्ट रूप से नामित पद्धति को कॉल करते हैं  NavbarBarHidden   यह एक त्रुटि फेंकना चाहिए , क्योंकि ऐसा कोई तरीका मौजूद नहीं है, इसके बजाय आपको वास्तविक प्राप्तकर्ता नाम का उपयोग करना चाहिए:  [self.navigationControllerNavigationBarHidden];

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:...

matlab - Using loops to get multiple values into a cell -

I have 31 topics (S1, S2, S3, S4, etc.) 3 images in each topic, opposite 1 IMG, Contrast 2 IMG and Contrast 3 Are IMG I p In a NX1 cell named P, I would like to use a loop to get all the paths of contrasts from all the subjects: data / S1 / contrast1.img / S1 / contrast2.img data / S1 / contrast3.img data / s2 / contrast1.img data / S2 / contrast2.img Data / S2 / contrast3.img ... Data / S31 / contast3.img This is what I've tried: A = {'S1', 'S2', 'S3', ..., 'S31'}; % All topics C = {'contrast1.img', 'contrast2.img', 'contrast3.img'}; For each = P = cell (31 * 3,1) for each topic, the required contrast images: Length = A for Jammu = 1: Length (C) P {j} = spm_select ('FPList', Fullfile (data_path, q {i}) sprint ('% s', cell2mat (c))); % Of each topic is to select three contrast images, it works in my script, it is probably not 100% correct, because I had to simplify this example.

python - Sequence Pattern recognition with Pybrain -

Image
I am constantly trying to use recurrent neural networks to classify a series of data. To be more specific, I have a sequence of sensor reading (which is continuous over time), I have to learn an algorithm which can detect the state related to this pattern, given the readings change. Example: Time step_1: 1.4 Time step_2: 1 Time step_3: 0.8 State = New Sequence: Time Phase 1: 0.4 Time Phase 2: 0.3 Time Phase 3: 0.1 State = Sitting I actually have 12 censors, I'm just showing a sequence of numbers for convenience. (Numbers are not real, I'm just trying to fulfill this idea)! I am trying to make my network with PyBrain RNN, however, I can not get a Data Set Container that can detect it, like information I tried to use sequential data But after some testing I came to know that this number is the next element in the sequence of numbers. Here's how I prepare my dataset: self.alldata = SequentialDataSet (ds.num_features, 1) # Now add samples to the dat...
