以下示例程序输出相同,但程序无法正常工作.

NSDirectoryEnumerator *directoryEnumerator = [[NSFileManager defaultManager]
                                   enumeratorAtPath:kDocdir];

for (NSString *pathi in directoryEnumerator)
{
   NSString *fileName_Manager = [pathi lastPathComponent];
   NSLog(@"fileName_Manager = %@",fileName_Manager);

   Artist *name_Databse =  [self.fetchedResultsController
                               objectAtIndexPath:IndexPath];
   NSLog(@"name_Databse     = %@",name_Databse.name);



   if ([fileName_Manager isEqualToString:name_Databse.name]) {
       NSLog(@"Same Name");
   }else{
       NSLog(@"Different Name");
   }

}

输出:

2013-04-25 15:37:43.256 Player[36436:907] fileName_Manager = alizée - mèxico - final j'en
2013-04-25 15:37:43.272 Player[36436:907] name_Databse     = alizée - mèxico - final j'en
2013-04-25 15:37:44.107 Player[36436:907] Different Name

名称中的特殊字符时无法正常工作.为什么会这样？谢谢 ...

这里有同样的问题:

NSPredicate *predicate = [NSPredicate predicateWithFormat:@"name == %@",[pathi lastPathComponent]];

我如何在这里进行编辑？

Apple告诉我,我的应用程序在启动时崩溃了.这是崩溃报告,但我不知道它意味着什么.可能的原因是什么？
