iphone - How to control other buttons' actions? -

-

नमस्ते इसलिए कहना है कि मुझे यह कोड है: 

  UIAlertView * alert = [[UIAlertView alloc ] InitWithTitle: @ "यै" संदेश: msg प्रतिनिधि: स्वयं रद्द करें बटनटाइट: @ "आगे बढ़ें ..." अन्य बटनटाइटल्स: @ "1", @ "2", शून्य];

मैं अन्य बटन "1" और "2" को कैसे नियंत्रित करूं? (मान लें कि अन्य सभी आवश्यक कोड जगह में हैं, जैसे कि अपरिभाषित चर msg)

धन्यवाद!

आपको अपने UIAlertView उदाहरण की संपत्ति सेट करने की आवश्यकता है (यानी चेतावनी ) और विधि को लागू करें।

मान लें कि आप चाहते हैं वर्तमान वर्ग UIAlertView के प्रतिनिधि होने के लिए आप कोड की निम्न पंक्ति का उपयोग करेंगे: 

  alert.delegate = self;

इसके बाद, आप मौजूदा वर्ग को। कोड में UIAlertViewDelegate प्रोटोकॉल को कार्यान्वित करने के लिए सेटअप करेंगे। उदाहरण के लिए:

<पूर्व> @ इंटरफेस मायक्लास: NSObject & lt; UIAlertViewDelegate & gt;

तब आप केवल चेतावनी दृश्य को लागू कर सकते हैं: clickedButtonAtIndex: .m फ़ाइल में विधि: 

  - चेतावनी दृश्य: एक क्लिक किया हुआ बटनअट इंडेक्स : I {NSLog (@ "आपने क्लिक किया% d।", I); }

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!

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...

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])
