很簡單:

-(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]];

}

記住 不要在viewDidLoad裡面設置工具條不隱藏!
