iphone - How to set the text of a back button on a UINavigationBar? -


संभव डुप्लिकेट:

स्थिति:
मेरे पास एक UIViewController है जो एक नेविगेशन नियंत्रक द्वारा संचालित है I मैं बस self.title = @ "title" को कॉल करके UIViewController को कवर करते हुए नेविगेशन बार के शीर्षक सेट करने में सक्षम हूं। लेकिन, मैं नेविगेशन पट्टी के बैक बटन टेक्स्ट को सेट करने में सक्षम होना चाहता हूं (अलग-अलग भाषाओं के लिए एन 'जैसे ..)

समस्या: < / Strong>
मुझे नहीं पता कि वापस बटन के पाठ को कैसे सेट करना है।

प्रश्न:
मैं इसके पीछे के बटन को कैसे सेट करूं यूआईनेविगेशन पट्टी (प्रोग्राम आईबी में नहीं)?

सेटटिटल मार्ग - यद्यपि काम लग सकता है, यह गलत है । यदि आप बारीकी से ध्यान देते हैं, तो आप देखेंगे कि नेविगेशन आइटम नए शीर्षक में बदल जाता है, जबकि नए दृश्य को पुश ViewController के माध्यम से देखने में एनिमेटेड किया जाता है। तथ्य यह है कि आपको अपने शीर्षक को देखने के लिए बहाल करना हैव्लैपीपीर कुल्डी है, जो इसके हैक प्रकृति का सुझाव देता है।

सही तरीके से आपके पुश ViewController से पहले करना है: 

 UIBarButtonItem * backButton = [[UIBarButtonItem alloc] initWithTitle: @ "बैक बटन टेक्स्ट" शैली: UIBarButtonItemStyleBordered लक्ष्य: शून्य कार्रवाई: शून्य]; [स्वयं। नेविगेशनइटम सेटबैकबर्टबूटनइटम: बैकबटन]; [बैकबटन रिलीज];

c++ - QtQuick: QQmlApplicationEngine failed to load component qrc:/main.qml:23 Invalid attached object assignment -

Looking at my thoughts below, am I barking the wrong tree? Or in the information given below, am I misusing the Qt API to get an error in the title? I'm trying to modify the sample to work with the default coefficic project generated from Qt Creator 3.3.0 (OpenSource). Qt 5.4.0 (GCC 4.6.1, 64bit) Based on. The first thing to look at after the code is that I stand by: The sample uses the main.cpp: qmlRegisterType & lt ; Squircle & gt; ("OpenGLUARMM", 1, 0, "Squircle"); QQuickView view; View.setResizeMode (QQuickView :: SizeRootObjectToView); View.setSource (QUrl ("QRC: ///scenegraph/openglunderqml/main.qml")); View.show (); Some name changes in my name. CPP qmlRegisterType & lt; Menuscreen & gt; ("OpenGLUnderQML", 1, 0, "Main Screen"); QQmlApplicationEngine engine; Engine.load (QUrl (QStringLiteral ("QRC: /main.qml"))); I'm not sure that the difference in using QQmlApplicationEngine...

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net - getting a value of selected radiobutton in LoadViewState -

Can I get the value of a selected radio button in the LoadViewState event of WebControl and how? All components are generated in codebehind, so I have those controls: Radiobutton list RLL; LISTIME leon; List liTwo; At this time I was stuck on that the overloaded loadviolet is not being implemented protected override zero load vivestat (object o) {action = Rbl.SelectedValue; Verb 2 = rll Selected item. value; Base.LoadViewState (O); } You also need to override the SaveViewState method. Radio button AFAIK has problems in saving their selected state.
