iphone - Need access to the cell in the tableView:heightForRowAtIndexPath: -

-

मुझे तालिका में tableView: heightForRowAtIndexPath: से मेरे सेल को एक्सेस करने की आवश्यकता है क्योंकि मैं उपयोग करना चाहता हूं मेरे पास ऊंचाई की गणना के लिए सीओटीएम सेल का डेटा है I मेरी कोशिकाओं को प्राप्त करने का एकमात्र तरीका है tableView: cellForRowAtIndexPath:

कॉल करने वाला यह है कि कॉलिंग tableView: cellForRowAtIndexPath: है वास्तव में कोशिकाओं को बनाने और उनके साथ कुछ भी करने से नहीं। जब एक ही सेल को ड्राइंग उद्देश्य के लिए उपयोग करने की आवश्यकता होगी, इसे फिर से बनाया जाएगा तो उसी सूचकांक के लिए सेल को दो बार बनाया जाता है।

इसलिए मुझे आश्चर्य है कि ऐसा करने के लिए एक अधिक प्रभावी तरीका है। मदद के लिए धन्यवाद।

आपके पास इस विधि में सेल तक पहुंच नहीं है क्योंकि यह नहीं है अभी तक अस्तित्व में है tableView: heightForRowAtIndexPath: को tableView: cellForRowAtIndexPath: । में सेल बनाने से पहले कहा जाता है।

लेकिन इससे कोई फर्क नहीं पड़ता क्योंकि आपको मॉडल की जानकारी नहीं पकड़नी चाहिए सेल ऑब्जेक्ट्स में कक्ष केवल विचार होते हैं और आपको हमेशा अपने मॉडल में एक सेल का निर्माण करने के लिए आवश्यक सभी डेटा रखना चाहिए।

Getting started consuming web services in a Ruby on Rails 3 application -

-
Then I'm starting to learn the rail. Now that the train has left 3, then I have to stay in the tracks to learn 3 Ways to Talk One of the things I want to learn how to do the web service with the rest of the third party / the use of work / method of creating a "mashup" application. I have done minimal work in this way with PHP and pre-built libraries. Can someone lead me to some resources, best practices, or do I have a quick 101 text type of API to start working with them? Should I use gems? Update: I'm trying to use the Google Books API (non-standardized) specifically. Since there is no client library for this API, I am thinking that other Ruby / Rail developers are working with APIs that do not come with Ruby Library. This is the reason why I am looking for a more general solution to work with the "fill the fill" API. Update: After some research, I'm going to the Net :: HTTP Library. All the tutorials that talked about it were quite old. ...

objective c - iPhone and it's wireless area -

-
Is this a way to find other iPhones in the category of wireless areas? So I give an example. I'm staying at the airport somewhere I have an iPhone too. I and the other iPhone owners are playing the same game. Is there any way to warn me and the other player that we are close to each other? Does this work even if we are not on the same wireless network, or there is no wireless? And if there is any way to do this, can you give me some starting point? Like a link where I can learn something like this or maybe this is probably the name of this process, because I do not know how to search about this topic in Google. Thanks in advance! Can be completed with peer-to-peer discovery and connectivity you are describing Game Kit Framework Originally I thought it works only through Bluetooth, but after watching it immediately, it seems that WiFi is also supported. Hope it helps!
