最初我创建了一个名为'mainView'的动态视图。在那里,我添加了导航栏。之后,我想向导航栏添加2个右侧栏按钮。如果我的代码是这样的,它的导航栏显示视图,但它没有显示正确的酒吧按钮。如何将多个栏按钮添加到导航栏
1.是否可以在没有导航控制器的情况下添加导航栏?
2.为什么没有显示右边的按钮?
//mainView Creation
UIView *mainView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
mainView.backgroundColor =[UIColor grayColor];
[self.view addSubview:mainView];
//NavigationBar
UINavigationBar *NavigationBar = [[UINavigationBar alloc]initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 45)];
NavigationBar.backgroundColor = [UIColor orangeColor];
[mainView addSubview:NavigationBar];
//rightbarView Creation
UIView *rightbarView = [[UIView alloc] init];
rightbarView.backgroundColor = [UIColor orangeColor];
//powerCut Button
UIButton *powerCutbutton = [[UIButton alloc] initWithFrame:CGRectMake(150, 20, 50, 14.01)];
[rightbarView addSubview:powerCutbutton];
UIImage *powercutimage = [UIImage imageNamed:@"powercut.jpg"];
[powerCutbutton setImage:powercutimage forState:UIControlStateNormal];
// addConnection button
UIButton *addConnectionbutton = [[UIButton alloc] initWithFrame:CGRectMake(210, 20, 50, 14.01)];
[rightbarView addSubview:addConnectionbutton];
UIImage *addimage = [UIImage imageNamed:@"add.png"];
[addConnectionbutton setImage:addimage forState:UIControlStateNormal];
// Barbutton item
UIBarButtonItem *item = [[UIBarButtonItem alloc] initWithCustomView:rightbarView];
//[self.navigationItem setRightBarButtonItems:[NSArray arrayWithObjects:powerCutbutton, addConnectionbutton, nil]];
// setting rightbar button item
self.navigationItem.rightBarButtonItem = item;
