iphone - 如何在导航栏上添加 2 个按钮？

Question

我正在使用 Split View Controller，它在第二个 View Controller 上有 2 个 View Controller ，我想在导航 Controller 的右侧添加两个按钮。我使用以下代码添加了一个有效的按钮:

UIBarButtonItem *barButton=[[UIBarButtonItem alloc] init];
    [barButton setCustomView:btnShare];
    self.navigationItem.rightBarButtonItem=barButton;

试过这个链接http://osmorphis.blogspot.in/2009/05/multiple-buttons-on-navigation-bar.html但未能成功。请帮我解决这个问题。

试试这个

NSMutableArray *arrRightBarItems = [[NSMutableArray alloc] init];
UIButton *btnSetting = [UIButton buttonWithType:UIButtonTypeCustom];
[btnSetting setImage:[UIImage imageNamed:@"settings.png"] forState:UIControlStateNormal];
btnSetting.frame = CGRectMake(0, 0, 32, 32);
btnSetting.showsTouchWhenHighlighted=YES;
[btnSetting addTarget:self action:@selector(onSettings:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *barButtonItem = [[UIBarButtonItem alloc] initWithCustomView:btnSetting];
[arrRightBarItems addObject:barButtonItem];

UIButton *btnLib = [UIButton buttonWithType:UIButtonTypeCustom];
[btnLib setImage:[UIImage imageNamed:@"library.png"] forState:UIControlStateNormal];
btnLib.frame = CGRectMake(0, 0, 32, 32);
btnLib.showsTouchWhenHighlighted=YES;
[btnLib addTarget:self action:@selector(onMyLibrary:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *barButtonItem2 = [[UIBarButtonItem alloc] initWithCustomView:btnLib];
[arrRightBarItems addObject:barButtonItem2];

UIButton *btnRefresh = [UIButton buttonWithType:UIButtonTypeCustom];
[btnRefresh setImage:[UIImage imageNamed:@"refresh.png"] forState:UIControlStateNormal];
btnRefresh.frame = CGRectMake(0, 0, 32, 32);
btnRefresh.showsTouchWhenHighlighted=YES;
[btnRefresh addTarget:self action:@selector(onRefreshBtn:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *barButtonItem1 = [[UIBarButtonItem alloc] initWithCustomView:btnRefresh];

[arrRightBarItems addObject:barButtonItem1];
self.navigationItem.rightBarButtonItems=arrRightBarItems;
