Xcode8.3 iOS10将文件从软件包复制到应用程序目录

Question

在Xcode8.3 for iOS10中，我试图将文件从软件包目录复制到应用程序专用目录。这对iOS6起到了很好的作用，但在iOS8以上并没有起作用。

我是索引文件在for循环中：

NSString* currentfilename = [[dbfileManager directoryContentsAtPath: bundleFolderPath] objectAtIndex:i]; 
NSString*s =[NSString stringWithFormat:@".db"]; 
//NSLog(@"getAllMapDBFileNames db file exist=%@",s); 
    if ([currentfilename rangeOfString:s].location != NSNotFound){ 
     NSString *tmpfilename=[[[currentfilename stringByReplacingOccurrencesOfString:@"-" withString:@" "] stringByReplacingOccurrencesOfString:@".db" withString:@""] capitalizedString]; 
     NSString *strdestination = [NSString stringWithFormat:@"%@/%@", bundleFolderPath,currentfilename]; 
     NSLog(@"DOES Exist! = %@",tmpfilename); 
     NSLog(@"strdestination = %@",strdestination); 
     NSString *toPath = [NSString stringWithFormat:@"%@/%@", dbappFolderPath,currentfilename]; 
     NSLog(@"toPath = %@",toPath); 
     [[NSFileManager defaultManager]copyItemAtPath:strdestination toPath:toPath error:NULL]; //&Error 
    } 

为什么iOS的8和拦截呢？

此代码实际工作！我不确定Xcode 8.3是否具有文件大小限制。
