Question

尝试创建plist文件。但是获取错误 [NSFileManager copyItemAtPath：toPath：error：]：源路径为

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];
}

如果请求的文件不存在，

- [NSBundle pathForResource:ofType:]将返回nil。确保应用包真的包含data.plist。

Plist NSFileManager copyItemAtPath：toPath：error：] source path is nil'
