[NSCFNumber _isNaturallyRTL] : 인식 할 수없는 선택기가 인스턴스로 전송 됨 0x605ac10

Question

내 앱이 크래시되어 해당 키워드가 표시되었습니다. 오류 및 경고가 없습니다. 어떤 몸이 나를 도울 수 있니?

-(void)viewWillAppear:(BOOL)animated{ 
DocSegmentedModel *docSegmentedModel = [docProperties objectAtIndex:index]; 
NSString *segmenid = docSegmentedModel.docSegmentId; 
NSFileManager *filemgr = [NSFileManager defaultManager]; 
NSDictionary *attribs; 
NSString *sizes; 

NSString *localFilePath = docSegmentedModel.docSegmentLocalPath; 
NSLog(@"segmen id : %@", segmenid); 

//get file name 
fileName.text = docSegmentedModel.docSegmentFileName; 

//get file size 
attribs = [filemgr attributesOfItemAtPath:localFilePath error:NULL]; 
sizes = [attribs objectForKey:@"NSFileSize"]; 


NSLog(@"local path : %@", localFilePath); 
NSLog(@"filesize : %@", sizes); 
    fileSize.text = sizes; 

[filemgr release]; 
[attribs release]; 

}

이 보였다 스택 인

fileSize.text = sizes를 설정하면 코드가 충돌합니다.

- (void)dealloc { 

[fileSize release]; 

[super dealloc]; 

}

Answer 1

_isNaturallyRTL가 NSString의 문서화 방법 :

이

는 할당 해제의 방법이다. 나는 fileSize이 UILabel이라고 가정하고 text 속성에 NSString을 할당해야한다고 가정합니다. 그러나 fileManager에서 반환 한 사전에는 unsigned long long 값이 포함 된 NSFileSize 키의 NSNumber 객체가 들어 있습니다. 따라서 NSNumber 개체를 NSString 속성에 할당하면 작동하지 않습니다.

시도 fileSize.text = [sizes stringVlue];.
