objective c - Using object declared in a method in another implementation in another file? -

-

मेरे पास एक टेबलव्यूव विधि है:

- (UITableViewCell *) तालिकादृश्य: (UITableView * ) ATableView cellForRowAtIndexPath: (NSIndexPath *) इंडेक्सपैथ

जो घोषित करता है: NSInteger row = [indexPath पंक्ति]; फ़ाइल तालिका में उपरोक्त विधि के साथ TableView.m और I दूसरी पंक्ति में 'पंक्ति' के मूल्य को दूसरे दृश्य में इस्तेमाल करना चाहते हैं और मुझे नहीं पता कि पंक्ति के मूल्य को अन्य फाइल में कैसे इस्तेमाल किया जा सकता है और पूरी परियोजना के लिए इसे जनता बनाओ - मैं चाहता हूं

बहुत सारे धन्यवाद!

यदि आप उपयोग करना चाहते हैं वे चर का दायरा आपके तरीकों में से एक के भीतर सीमित है, तो आप इसे बाहर का उपयोग नहीं कर सकते।

आपको इसे एक सदस्य वैरिएबल बनाना होगा और इसे क्लास के एक उदाहरण से पूछें। 

  @ इंटरफेस माइटेबल {NSInteger पंक्ति; // सदस्य चर} @ प्रॉपर्टी (नॉनैटोमिक, असाइन करें) एनएसआईएनटेगर पंक्ति; // इसे एक संपत्ति बनाने से इसे अन्य कक्षाओं से पहुँचा जा सकता है @end ... @ कार्यान्वयन @ सिंथेसाइज़ पंक्ति; // @ प्रॉपर्टी के साथ संयोजन में उपयोग किया जाता है .... - (UITableViewCell *) तालिकादृश्य: (UITableView *) aTableView cellForRowAtIndexPath: (NSIndexPath *) सूचकांक {... पंक्ति = [सूचकांक पंक्ति]; // आपके द्वारा उपयोग की जाने वाली चर सेट करता है ...} ....   
 अन्य वर्ग:  
  [myTable पंक्ति]; // वैरिएबल     का उपयोग करें

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

javascript - What is an alternative to using getElementByClass for hiding multiple elements? -

-
I have a page with some links that I would like to be able to toggle with two buttons. It works with a link using getElementById, but I need to toggle some of those groups. I started with it, but it failed to work. I've heard that GetElementByClass has worked with everything but IE, but I'm using Opera 11.5 and it still does not work. I've searched a bit, but I'm new to some JavaScript and most of the explanation is not understood. Does anyone help me with a simple option, or can I help me fix the problem I've made? This is a test page I was using. & lt; Head & gt; & Lt; Script type = "text / javascript" & gt; Function hideNames () {document.getElementByClass ("WebName"). Style.display = "none"; } Function ShowName () {document.getElementByClass ("WebName"). Style.display = "inline"; } & Lt; / Script & gt; & Lt; / Head & gt; & Lt; Body & gt; & Lt; P class = "web...

c# - GetType() == type perfomance question -

-
I am making an XNA game and I am calling the following updates 2 to 20 times the code. I tried googling and it seems that it is half slow, so I thought I was asking what kind of fast way to compare the type? code: Public modifier for this [type type] {for (int i = 0; i & lt; this.Qount; i ++) {if ( It [I.] Type GETType () ==) {Please return this [ii]; }} New NotImplementedException Throw ("Fix It"); } Set {for (int i = 0; i & lt; this.Qount; i ++) {if (this [i]. Type GetType () ==) {this [i] = value; }} If (System. Diagnostics.Debugor.ISAcredited) system. Diagnostics. Debugger. Break (); }} This code is in the modifier collection section which comes from a list. The modifier is a part of the particle engine. In addition, my game is not in a situation where I can actually do this test, so I can not test it, but should it work right? I read something about runtime typhanies, which is fast, should I use it? Thanks a lot! Edit: What I'm aiming to do ...
