问题描述
我想向 UINavigationbar 添加许多 UIBarButtonItem ，而不仅仅是左右按钮：
I want to add many UIBarButtonItem's to a UINavigationbar, not just right and left buttons:
logoButton = [[UIBarButtonItem alloc] initWithTitle:@"A Button" style:UIBarButtonItemStyleBordered target:self action:@selector(logoButtonAClicked:)];
logoButton2 = [[UIBarButtonItem alloc] initWithTitle:@"B Button" style:UIBarButtonItemStyleBordered target:self action:@selector(logoButtonBClicked:)];
logoButto3 = [[UIBarButtonItem alloc] initWithTitle:@"C Button" style:UIBarButtonItemStyleBordered target:self action:@selector(logoButtonCClicked:)];
self.navigationController.navigationBarHidden = NO;
self.title = @"Title";
NSArray* items = [[NSArray alloc] initWithObjects:logoButtonA, logoButtonB, logoButtonC, nil];
self.navigationController.navigationBar.items = items;
我在<$ c上获得 SIGBRT $ c> self.navigationController.navigationBar.items = items;
I get a SIGBRT on self.navigationController.navigationBar.items = items;
如何添加多个 UIBarButtonItem s到 UINavigationBar ？
推荐答案
将 UIBarButtonItem 实例添加到 UINavigationItem ，而不是 UINavigationBar 。所以你可以这样做：
You need to add UIBarButtonItem instance to a UINavigationItem, not to a UINavigationBar. So you can do this as:
NSArray *buttonArray = [NSArray arrayWithObjects:logoButton, logoButton2, logoButton3, nil];
self.navigationItem.leftBarButtonItems = buttonArray;
如果您想要右侧的按钮，请使用 rightBarButtonItems 。
If you want your buttons on the right, use rightBarButtonItems.
