UIBarButtonItem *previousBarButtonItem = [[UIBarButtonItem alloc] //init];
initWithTitle:@"<"
style:UIBarButtonItemStyleBordered
target:self
action:@selector(previousBarButtonAction:)];
self.navigationItem.leftBarButtonItem = previousBarButtonItem;
[previousBarButtonItem release];
UIBarButtonItem *nextBarButtonItem = [[UIBarButtonItem alloc] //init];
initWithTitle:@">"
style:UIBarButtonItemStyleBordered
target:self
action:@selector(nextBarButtonAction:)];
self.navigationItem.rightBarButtonItem = nextBarButtonItem;
[nextBarButtonItem release];
//This Portion For UIToolbar
topToolBar = [UIToolbar new];
topToolBar.barStyle = UIBarStyleDefault;
[topToolBar sizeToFit];
topToolBar.frame = CGRectMake(50, 410, 280, 50);
//Add buttons
UIBarButtonItem *systemItem1 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd
target:self
action:@selector(pressButton1:)];
UIBarButtonItem *systemItem2 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAction
target:self
action:@selector(pressButton2:)];
UIBarButtonItem *systemItem3 = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemCamera
target:self action:@selector(pressButton3:)];
//Use this to put space in between your toolbox buttons
UIBarButtonItem *flexItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace
target:nil
action:nil];
//Add buttons to the array
NSArray *items = [NSArray arrayWithObjects: systemItem1, flexItem, systemItem2, flexItem, systemItem3, nil];
//release buttons
[systemItem1 release];
[systemItem2 release];
[systemItem3 release];
[flexItem release];
//add array of buttons to toolbar
[topToolBar setItems:items animated:NO];
self.navigationItem.titleView = topToolBar;
这是我当前的编码位置，现在我在uitoolbar中有4个按钮，但是只能看到3个按钮，所以当我要按下next或上一个按钮以查看uitoolbar框架之外的其他按钮时，我想移动此工具栏??
this is my current coding position now i have 4 buttons in the uitoolbar but only 3 button can see so i want to move this toolbar when i will press next or previous button to see the others button whose are out of frame of uitoolbar??
我可以使用uiview动画滚动导航栏项，但是现在我的问题是，当我按下next/prev按钮时，它会根据uitoolbar坐标的更改从当前位置移动，并在pre /下一个baritem框架，该框架不在uitoolbar项中.但是应该在uiview中使用，并且应该在uiview中更改坐标，而不是超出视图范围...现在告诉我该怎么办.
I able to scroll the navigation bar item using uiview animation but now my problem is when i press the next/prev button then it is moving from the current place according to the changing of the coordinate of the uitoolbar and moving over the pre/next baritem frame whose are not in the uitoolbar items. but it should be wothin a uiview and should change the coordinate within the uiview not out of the view...now tell me what can i do for this problem.
推荐答案
首先，在图中看到的NavigationBar实际上是UIToolBar.不幸的是，不可能再在UINavigationBar上添加控件.但是您可以使用UIToolBar实现完全相同的UI，您可以在其中添加任何控件.
Firstly in figure the NavigationBar you are seeing is actually UIToolBar. Unfortunately it is not possible to add anymore controls on the UINavigationBar. But you can achieve exactly same UI with UIToolBar where you can add any controls.
因此要实现此目的，请使用UIToolBar而不是UINavigationBar.还可以使用具有自定义标题的UIBarButtonItem来实现 Next 和 Previous 功能.
So to achieve this use UIToolBar and not UINavigationBar. Also use UIBarButtonItem with custom title to achieve Next and Previous functionality.

但这全部说明了使用代码的原因.代替使用 Interface Builder ，使用UIToolBar变得太容易了(如果编码不是很重要).
But this all explains using codes. Instead using Interface Builder, it becomes too easy to use UIToolBar (if coding is not so important).
