iosUIToolBar工具条的使用

很简单:

-(void)viewWillAppear:(BOOL)animated

{

    [superviewWillAppear:animated];

    

    self.navigationController.toolbarHidden =NO;

}

- (void)viewDidLoad {

    [superviewDidLoad];

    // Do any additional setup after loading the view.

   // self.navigationController.toolbarHidden = NO;

    self.view.backgroundColor = [UIColorredColor];

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

    UIBarButtonItem *two = [[UIBarButtonItemalloc]initWithBarButtonSystemItem:UIBarButtonSystemItemBookmarkstarget:nilaction:nil];

    UIBarButtonItem *three = [[UIBarButtonItemalloc]initWithBarButtonSystemItem:UIBarButtonSystemItemActiontarget:nilaction:nil];

    UIBarButtonItem *four = [[UIBarButtonItemalloc]initWithBarButtonSystemItem:UIBarButtonSystemItemEdittarget:nilaction:nil];

    UIBarButtonItem *flexItem = [[UIBarButtonItemalloc]initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpacetarget:nilaction:nil];

    [selfsetToolbarItems:[NSArrayarrayWithObjects:flexItem, one, flexItem, two, flexItem, three, flexItem, four, flexItem,nil]];

    

}

记住 不要在viewDidLoad里面设置工具条不隐藏!
