ios - Plist NSFileManager copyItemAtPath:toPath:error:] 源路径为 nil'

Question

试图创建 plist 文件。但在 [NSFileManager copyItemAtPath:toPath:error:] 中出错：源路径为 nil

有人知道为什么会这样吗？非常感谢..

AppDelegate.h：

NSError*error;
NSArray*pathes=NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString*documentDirectory=[pathes objectAtIndex:0];//first dir in app dir.
NSString*path=[documentDirectory stringByAppendingPathComponent:@"data.plist"];

NSFileManager*filemanager=[NSFileManager defaultManager];
if(![filemanager fileExistsAtPath:path])
{
    NSString*bundle=[[NSBundle mainBundle]pathForResource:@"data" ofType:@"plist"];//check if plist file exist;



    [filemanager copyItemAtPath:bundle toPath:path error:&error];
    NSMutableDictionary*data=[[NSMutableDictionary alloc]initWithContentsOfFile:path];
    NSArray*arr=[[NSArray alloc]init];
    [data setObject:arr forKey:@"arr"];
    [data writeToFile:path atomically:YES];
}

- [NSBundle pathForResource:ofType:]nil如果请求的文件不存在则返回。确保应用程序包确实包含data.plist.
