iphone - Why am I getting this warning about my app delegate and CLLocationManageDelegate? -

-

इस बिल्कुल सरल UIViewController subclass विधि का निरीक्षण करें: 

  - (IBAction) launchSearch {OffersSearchController * खोज = [[ऑफ़र्ससर्च कंट्रोलर एलोक] इनिट वाइटएनआईबीएन: @ "ऑफ़र्सस्चर्च वीव्यू" बंडल: शून्य]; EverWondrAppDelegate * del = [UIApplication साझाअनुप्रयोग] .delegate; [Del.navigationController pushViewController: खोज एनिमेटेड: हाँ]; [खोज जारी]; }

उस पंक्ति पर जहां मुझे * डेल मिलता है, मुझे एक कंपाइलर चेतावनी मिल रही है जो पढ़ता है, टाइप 'id & lt; UIApplicationDelegate & gt;' 'CLLocationManagerDelegate' प्रोटोकॉल के अनुरूप नहीं है । वास्तव में, मेरा ऐप प्रतिनिधि उस प्रोटोकॉल के अनुरूप है, और जो मैं कर रहा हूं उसके साथ ऐसा करने के लिए कुछ भी नहीं है। तो उस संदेश के साथ क्या हो रहा है?

द्वितीयक प्रश्न: कभी-कभी मैं अपने नेविगेशन नियंत्रक को self.navigationController के माध्यम से प्राप्त कर सकता हूं, और कभी-कभी मैं नहीं कर सकता, और मेरे ऐप पर जाना पड़ता है प्रतिनिधि की संपत्ति इसे पाने के लिए मैं यहाँ कर रहा हूं।

इसे आज़माएं: 

  EverWondrAppDelegate * del = (EverWondrAppDelegate *) [UIApplication साझाअनुप्रयोग] .delegate;

अपने दूसरे प्रश्न के संबंध में: पता नहीं क्यों ये हो रहा है।

windows - Heroku throws SQLITE3 Read only exception -

-
After I deploy the app to Heroku, I have to run migration scripts and get this error message ... ITES \ padrino \ prophetmargin & gt; Heroku Rack AR: Rack mutated! SQLite3 :: ReadOnlyException: only one try to write database to read: CREATE TABLE "schema_migrations" ( "version" varchar (255) NOT NULL) /disk1/home/slugs/215264_925fd2c_65a3/mnt/.bundle/gems/gems/ padrino-core- is 0.9.11 / lib / padrino-core / cli / rake.rb: 9: in `init ' how can this be? I also tried to run Heroku dbpush SQLite: //db/my-db.db and that did not work Horoku sqlite3 but using postgres does not do. I'm not sure why you are receiving this error, however, as I have used sqlite3 in development and when pushing it into its travel, they do some magic which migrates to postgrads. I'm absolutely sure how Heroku does 'backwash' this database but it seems that this is happening to you because it's the SQLite db file which is obviously due to Heroku's...

php - Login to icq account to receive messages from contact #12345678 -

-
What's the way php-script is running, which does the following: - Enter the icq-account - Received Existing contacts are all messages (if any) from # 12345678 and - write those messages in an array such as $ Messages = array (); Edit I like to answer: "Blaee" is a good, active community, it is often updated because ICQ changes its internal changes Let's see: The first result of that: This class can be used to communicate with other ICQ consumers. This can: Non-interception with an ICQ server Authenticate as a given user Get offline message Send and receive messages (...) I would say that code Looking for you.

python - rename keys in a dictionary -

-
I want to change the names of keys in a dictionary which are ints, and I need them so that the inputs with key zero They can sort correctly. For example, my keys are like this: '1', '101', '11' and I may need them: '001', '101', '011' What is doing, but I know that there is a better way tmpDict = {} in the ADC for the old: t MpDict ['% 04d'% int (olden)] = addict [oldkey] New controlled = tmpDict You are going wrong about this if you want to draw entries on a line in a specific way, then you have to sort on the extraction. for sorted (D, key = int): print '% s:% R'% (k, d [k])
