Question

如何在导航栏的左侧同时显示后退按钮和另一个按钮？因为这是一个ipad应用程序，所以有多个按钮的空间。但我只能在导航仪上每侧显示一个按钮...

Answer 2

iOS现在支持同一侧的多个按钮。来自 UINavigationItem 文档：

自定义视图

  titleView  property
  leftBarButtonItems  property
  leftBarButtonItem  property
  rightBarButtonItems  property
  rightBarButtonItem  property
– setLeftBarButtonItems:animated:
– setLeftBarButtonItem:animated:
– setRightBarButtonItems:animated:
– setRightBarButtonItem:animated:

所以，基本上，你会写这样的东西在左边添加两个按钮：

UIBarButtonItem *refreshBtn = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh target:self action:@selector(refreshPlans:)];
UIBarButtonItem *selectYearBtn = [[UIBarButtonItem alloc] initWithTitle:@"Select Year" style:UIBarButtonSystemItemAction target:self action:@selector(selectYear)];
self.navigationItem.leftBarButtonItems = [[NSArray alloc] initWithObjects: refreshBtn, selectYearBtn, nil];

不幸的是，我还没有在Storyboard中看到过这样做的方法。希望这会有所帮助。

    UIBarButtonItem *btn0 = [[UIBarButtonItem alloc] initWithTitle:@"1" style:UIBarButtonItemStylePlain target:self action:@selector(tapLevel0)];

    UIBarButtonItem *btn1 =[[UIBarButtonItem alloc] initWithTitle:@"<2" style:UIBarButtonItemStylePlain target:self action:@selector(tapLevel1:)];

    UIBarButtonItem *btn2 = [[UIBarButtonItem alloc] initWithTitle:@"<3" style:UIBarButtonItemStylePlain target:self action:@selector(tapLevel2:)];

    UIBarButtonItem *space = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil];
    space.width = 10;

    UIBarButtonItem *space2 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil];
    space2.width = 10;

  //  UIBarButtonItem *refreshButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh target:self action:@selector(refreshItem)];
    self.navigationItem.leftBarButtonItems = [NSArray arrayWithObjects:btn0, space, btn1, space2, btn2, nil];
