Question

我希望控制器同时具有后退按钮和菜单按钮，如同给定图像一样。amazon app

但问题是即使在增加x轴值后它也不会向右移动。因此，我无法添加返回按钮图像。这就是我现在正在做的事情。

button  = [[UIButton alloc] initWithFrame:CGRectMake(200, 100, 100, 25)];
[button setImage:[UIImage imageNamed:@"menu.png"] forState:UIControlStateNormal];
[button addTarget:[SlideNavigationController sharedInstance] action:@selector(toggleLeftMenu) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:button];
[SlideNavigationController sharedInstance].leftBarButtonItem = rightBarButtonItem;

Answer 1

试试这个，

UIBarButtonItem *btnBack = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAction target:self action:@selector(back)];
UIBarButtonItem *btnMenu = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh target:self action:@selector(menu)];
[self.navigationItem setLeftBarButtonItems:[NSArray arrayWithObjects:btnBack, btnMenu, nil]];

Answer 2

在您的代码中，您专门用barBarButtonItem替换了后退按钮。

顺便说一下，你的命名有点令人困惑，你正在将rightBarButtonItem分配给navigationController的leftBarButtonItem。

[SlideNavigationController sharedInstance].navigationItem.leftBarButtonItems= @[leftButton,menuButton]; // this will assign both button on the left side. same thing for rightBarButtonItems

稍微向右移动菜单按钮
