如何在导航栏上添加2个按钮？
我正在使用Split View Controller ，它在第二个视图控制器上有2个View控制器我想在导航控制器的右侧添加两个按钮。 我使用以下代码添加一个工作的按钮：
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但是没能成功。请帮我解决这个问题。
尝试这个
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;
[self.navigationItem setRightBarButtonItem:[[UIBarButtonItem alloc] initWithCustomView:[GlobalMethods buttonWithImage:@"btn_home" heighlightImageName:@"btn_home_h" buttonFrame:CGRectMake(2, 1, 34, 34) selectorName:@selector(buttonHomeClicked:) target:self]]]; UIButton *tempButton = [UIButton buttonWithType:UIButtonTypeCustom]; [tempButton setFrame:CGRectMake(240, 5, 34, 34)]; [tempButton addTarget:target action:selectorName forControlEvents:UIControlEventTouchUpInside]; [tempButton setImage:[self getImageFromResource:normalImageName] forState:UIControlStateNormal]; [tempButton setImage:[self getImageFromResource:heighlightImageName] forState:UIControlStateHighlighted]; [tempButton setImage:[self getImageFromResource:@"btn_fav_h"] forState:UIControlStateSelected]; [self.navigationController.navigationBar addSubview:self.buttonFavorite];
创建两个uibarbuttonitem并在数组中添加两个，然后在导航栏中添加整个数组
UIBarButtonItem *addButton = [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(addAttachmentClicked:)]; UIBarButtonItem *sendButton = [[UIBarButtonItem alloc] initWithTitle:LS(@"Send") style:UIBarButtonItemStyleBordered target:self action:@selector(sendClicked:)]; self.navigationItem.rightBarButtonItems = @[addButton,sendButton];
试试你的代码
UIButton *btnLogOut = [UIButton buttonWithType:UIButtonTypeCustom]; btnLogOut.frame = CGRectMake(0, 0, 62, 31); [btnLogOut setImage:[UIImage imageNamed:@"logout_new.png"] forState:UIControlStateNormal]; [btnLogOut addTarget:self action:@selector(logoutButtonPressed:) forControlEvents:UIControlEventTouchUpInside]; UIBarButtonItem *logOutBarButton = [[UIBarButtonItem alloc] initWithCustomView:btnLogOut]; UIButton *btnError = [UIButton buttonWithType:UIButtonTypeCustom]; btnError.frame = CGRectMake(0, 0, 62, 31); [btnError setImage:[UIImage imageNamed:@"list-icon.png"] forState:UIControlStateNormal]; [btnError addTarget:self action:@selector(logoutButtonPressed:) forControlEvents:UIControlEventTouchUpInside]; UIBarButtonItem *errorButton = [[UIBarButtonItem alloc] initWithCustomView:btnError]; NSArray *navigationBarBtnArray=[NSArray arrayWithObjects:errorButton,logOutBarButton, nil]; self.navigationItem.rightBarButtonItems=navigationBarBtnArray;
尝试这个
UIBarButtonItem *rightButton = [[UIBarButtonItem alloc] initWithTitle:@"Done" style:UIBarButtonItemStyleDone target:nil action:nil]; self.navigationItem.rightBarButtonItem = rightButton; [rightButton release];
让UIView添加你想要的多个按钮。 然后用
UIBarButtonItem *myBarbtn=[[UIBarButtonItem alloc] initWithCustomView:buttonsView]; self.navigationItem.rightBarButtonItem = myBarbtn;
为此使用分段控制
UISegmentedControl* segmentedControl = [[UISegmentedControl alloc] initWithItems:[NSArray array]]; [segmentedControl setMomentary:YES]; [segmentedControl insertSegmentWithImage:[UIImage imageNamed:@"sample1.png"] atIndex:0 animated:NO]; [segmentedControl insertSegmentWithImage:[UIImage imageNamed:@"sample2.png"] atIndex:1 animated:NO]; segmentedControl.autoresizingMask = UIViewAutoresizingFlexibleWidth; segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar; [segmentedControl addTarget:self action:@selector(segmentedAction:) forControlEvents:UIControlEventValueChanged]; UIBarButtonItem * segmentBarItem = [[UIBarButtonItem alloc] initWithCustomView: segmentedControl]; self.navigationItem.rightBarButtonItem = segmentBarItem;
创建一个UIBarButtonItem数组并将其传递给
- (void)setRightBarButtonItems:(NSArray *)items animated:(BOOL)animated
UINavigationItem方法。
只需使用UISegmentedControl而不是UIButton 。
然后将模式更改为“瞬间”并在更改时添加操作。
触发操作后，请检查selectedSegmentIndex以了解selectedSegmentIndex段。
