ios - leftbarbuttonitem脱离框架

Question

我已应用代码向uibarbuttonitem添加uibutton，问题是按钮脱离框架

该代码是

        a1 = [UIButton buttonWithType:UIButtonTypeCustom];
    [a1 setFrame:CGRectMake(0.0f, 0.0f, 65.0f, 63.0f)];
    [a1 addTarget:self.slideMenuController action:@selector(toggleMenu) forControlEvents:UIControlEventTouchUpInside];
    [a1 setImage:[UIImage imageNamed:@"menu-enable-bt.png"] forState:UIControlStateNormal];

    UIView *view =[[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, 65.0,63.0) ];
    [view addSubview:a1];

    menuButton = [[UIBarButtonItem alloc] initWithCustomView:view];


    rootViewController.navigationItem.leftBarButtonItem = menuButton;

我不知道怎么了

UINavigationBar高度为44，您设置框架(0.0、0.0、65.0、63.0)，更改框架高度以适合UINavigationBar
