ios - NSManagedObject and Arrays -

-

मैं निम्नलिखित कोड में ठोकर खाई हूं 

  NSManagedObject * object = [[NSMutableArray Alloc] initWithObjects: @ "पहले", @ "सेकंड", शून्य];   
 मुझे आश्चर्य है कि यह वास्तव में संकलन क्यों कर रहा है और रनटाइम के दौरान कोई भी अपवाद नहीं फेंकता है।  
  po ऑब्जेक्ट   
 > रिटर्न:  
 
 __ NSArrayM 0x17005fc20 & gt; (प्रथम, दूसरा)    
 
 
 उद्देश्य-सी गतिशील रूप से टाइप किया गया है वहाँ एक बेमेल है, और संकलक उस असाइनमेंट पर चेतावनी पैदा करना चाहिए, और किसी भी संदेश पर आप "ऑब्जेक्ट" पास करते हैं जो NSManagedObject का समर्थन नहीं करता है। हालांकि, यह पूरी तरह से वैध है। कृपया इसे ठीक करें।

php - How can I cram 6+31 numeric characters into 22 alphanumeric characters? -

-
I have a 6 digit number and a 31-digit number (such as "234536" and "201103231043330478311223582826") that I The API needs to be crawled in the same 22-character alphanumeric field that uses PHP. I tried to convert each one to 32 (using custom code could not handle the base_convert () large number) and to connect with a single-character delimiter, but It only gives me 26 characters This is a restore API, so the letters should be URI-protected. I would like to do a database table cross with two references without reference to another reference value, if possible, any suggestions? Instead use a radix of 62. This will give you 22 characters for the top, 3.35 for the pre and 17.3 for the next. & gt; & Gt; & Gt; Math.log (10 ** 6) /math.log (62) 3.3474826039165504 & gt; & Gt; & Gt; Math.log (10 ** 31) /math.log (62) 17.295326786902177
