ios - EXC_BAD_ACCESS StringWithFormat -


इस पद्धति में क्या गलत है? 

  - (शून्य) randomInteger {count = ( Arc4random ()% 5000) + 5000; NSString * countString = [NSString stringWithFormat: @ "% i", गिनती]; if ([countString rangeOfString: @ "0"]। स्थान! = NSNotFound & amp; amp; [countString rangeOfString: @ "1"] स्थान! = NSNotFound & amp; amp; [countString rangeOfString: @ "2"] स्थान! = NSNotFound & amp; amp; [countString rangeOfString: @ "3"] स्थान! = NSNotFound) {score.text = [NSString stringWithFormat: @ "% i", गिनती]; } और {[आत्म यादृच्छिक इन्टेगीर]; }}   
  गिनती  एक पूर्णांक है जिसे निम्नलिखित,  int count = 0;  का उपयोग करके घोषित किया गया है। मुझे लाइन नंबर 3 पर एक EXC_BAD_ACCESS त्रुटि मिलती है। मेरा मानना ​​है कि विधि के द्वारा दूसरी बार ऐसा होता है क्योंकि अगर मैं  [self randomInteger] टिप्पणी करता हूं;  कोई त्रुटि संदेश फेंका नहीं जाता है।   
 
 
 यह बहुत अधिक स्टैक स्पेस का उपयोग कर सकता है क्योंकि पुनरावर्तन।  
 < कोड> - (शून्य) यादृच्छिक इन्टेजर {जबकि (सच) {int count = arc4random_uniform (5000) + 5000; NSString * countString = [NSString stringWithFormat: @ "% i", गिनती]; If ([countString rangeOfString: @ "0"] स्थान! = NSNotFound & amp; amp; [countString rangeOfString: @ "1"] स्थान! = NSNotFound & amp; amp; [countString rangeOfString: @ "2"] स्थान! = NSNotFound & amp; amp; [countString रेंज ओफ़स्ट्रिंग: @ "3"] स्थान! = NSNotFound) {score.text = countString; टूटना; }}}     पर क्लिक करें

In brief, the wrapper module is inserted during posting and the status of an entry is changed to 'modified' . Before changing the state, the state is set to 'separate', but calling attachments () causes the same error to be thrown away. I am using EF 6.
