XCode8.3 IOS10将文件从软件包复制到App Directory

Question

在xcode8.3中，iOS10我正在尝试将文件从包装目录复制到应用程序专用目录。这对ios6效果很好，但在ios8及以上。

i是for循环中的索引文件：

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 8及向上阻止它？

此代码实际作品！我不确定Xcode 8.3是否具有文件大小限制。
