UINavigationController的使用心得（一）

同理与UITabBarController，一些普遍性的操作就不提到了，大家可以参考下（http://blog.csdn.net/totogo2010/article/details/7681879）的博客。

但是下面这幅图片还是得引用下：

根据网上的一些资料，自己做了一个demo，先上效果

以上的效果是很丑的（只是表达一个意思）。

首先使用到了MainViewController，FirstViewController两个视图。

先创建FirstViewController视图。

 ///  MainViewController.m 

- (void)viewDidLoad

{

    [superviewDidLoad];

    //创建导航

    FirstViewController *viewController = [[FirstViewControlleralloc] initWithNibName:nilbundle:nil];

    viewController.title =@"firstViewController";

    UINavigationController *navigationBar = [[UINavigationControlleralloc] init];

    self.navigationController = navigationBar;

    [navigationBar pushViewController:viewControlleranimated:YES];

    [self.view addSubview:navigationBar.view];

    [navigationBar release];

}

1.NavigationBar的使用

首先在 MainViewController.h文件中

@property(strong,nonatomic)UINavigationController *navigationController;

在MainViewController.m 中

//1.设置navigationBar的文本颜色

    self.navigationController.navigationBar.tintColor = [UIColorredColor];

//2.设置navigationBar的背景图片

    UIImage *navBarImage = [UIImageimageNamed:@"bottomBK.png"];

    UIImageView *imageView = [[UIImageViewalloc] initWithImage:navBarImage];

    [self.navigationController.navigationBaraddSubview:imageView];

// 3.自定义设置navigationBar的背景图片 的方式(采用类目的方式)

    参考 http://blog.csdn.net/zhuzhihai1988/article/details/7705308

在FirstViewController.m文件中

// 1.上面导航栏中的 左边按钮（系统）

    UIBarButtonItem *leftButton = [[UIBarButtonItemalloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCanceltarget:nilaction:@selector(leftButtonAction:)];

    self.navigationItem.leftBarButtonItem = leftButton;

    [leftButton release];

//2.上面导航栏中的  自定义左边按钮

    UIBarButtonItem *coutomButton = [[UIBarButtonItemalloc] initWithTitle:@"asdfasdf"style:UIBarButtonItemStyleDone target:self action:@selector(rightButtonAction1:)];

    UIButton *button11 = [UIButtonbuttonWithType:UIButtonTypeCustom];

    [button11 setFrame:CGRectMake(0,0, 40, 30)];

    [button11 setBackgroundColor:[UIColorredColor]];

    [button11 setBackgroundImage:[UIImageimageNamed:@"102.png"]forState:UIControlStateNormal];

    [button11 setBackgroundImage:[UIImageimageNamed:@"102-sel.png"]forState:UIControlStateHighlighted];

    coutomButton.customView = button11;

    [button11 release];

    self.navigationItem.leftBarButtonItem = coutomButton;

    [coutomButton release];

//3.自定义中间titleView

    UIButton *titleButton = [UIButtonbuttonWithType:UIButtonTypeRoundedRect];

    titleButton.frame = CGRectMake(0,0, 40, 30);

    [titleButton setBackgroundColor:[UIColorwhiteColor]];

    [titleButton setTitle:@"titlView"forState:UIControlStateNormal];

    self.navigationItem.titleView = titleButton;

    [titleButton release];

// 4.上面导航栏中的右边按钮（系统）

  UIBarButtonItem *rightButton = [[UIBarButtonItemalloc] initWithBarButtonSystemItem:UIBarButtonSystemItemComposetarget:selfaction:@selector(rightButtonAction1:)];

    self.navigationItem.rightBarButtonItems = [NSArrayarrayWithObjects:rightButton, nil];

    [rightButton release];

注意事项：

  Navigationbar 的位置坐标和宽度，高度是修改不了的。 即bar.frame = CGRectMake(0,20,self.view.bounds.size.width,30);重新设置navigationbar是不起作用的。

2.NavigationToolBar的使用

在MainViewController.m文件中

//1.显示底部工具栏

    self.navigationController.toolbarHidden =NO;

//2.设置底部工具栏的背景图片

    UIImage *navBarImage11 = [UIImageimageNamed:@"bottomBK.png"];

    UIImageView *imageView11 = [[UIImageViewalloc] initWithImage:navBarImage11];

    [self.navigationController.toolbaraddSubview:imageView11];

//3.设置底部工具栏的文本颜色

    self.navigationController.toolbar.tintColor = [UIColorredColor];

//4.两个自定义tool下的按钮和系统save按钮

    UIBarButtonItem *custom = [[UIBarButtonItemalloc] initWithBarButtonSystemItem:UIBarButtonSystemItemSearchtarget:nilaction:nil];

    UIButton *button3 = [[UIButtonalloc] initWithFrame:CGRectMake(0,0, 60,44)];

    [button3 setBackgroundImage:[UIImageimageNamed:@"102.png"]forState:UIControlStateNormal];

    custom.customView = button3;

    UIBarButtonItem *add = [[UIBarButtonItemalloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAddtarget:nilaction:nil];

    UIButton *button4 = [[UIButtonalloc] initWithFrame:CGRectMake(0,0, 60,44)];

    [button4 setBackgroundImage:[UIImageimageNamed:@"102.png"]forState:UIControlStateNormal];

    add.customView = button4;

    UIBarButtonItem *save = [[UIBarButtonItemalloc] initWithBarButtonSystemItem:UIBarButtonSystemItemSavetarget:nilaction:nil];

    UIBarButtonItem *save3 = [[UIBarButtonItemalloc] initWithBarButtonSystemItem:UIBarButtonSystemItemSavetarget:nilaction:nil];

    UIBarButtonItem *save1 = [[UIBarButtonItemalloc] initWithBarButtonSystemItem:UIBarButtonSystemItemSavetarget:nilaction:nil];

    UIBarButtonItem *save2 = [[UIBarButtonItemalloc] initWithBarButtonSystemItem:UIBarButtonSystemItemSavetarget:nilaction:nil];

    self.toolbarItems = [NSArrayarrayWithObjects:custom,add,save,save1,save2,save3,nil];

    [button3 release];

    [button4 release];

    [custom release];

    [add release];

    [save release];

    [save1 release];

    [save2 release];

    [save3 release];

注意事项：

  NavigationToolbar 的位置坐标和宽度同NavigationBar的一样不能修改的。
