为UIToolBar工具条添加各种各样的UIBarButtonItem

[http://blog.iosxcode4.com/?p=100]

1.首先，我们看一下UIBarButtonItem有哪些初始化方法，这也可以看出，它可以被定义为什么东东，然后加到UIToolBar上面去。

根据SDK的文档，我们可以发现UIBarButtonItem有如下几种初始化的方法：

-initWithTitle

-initWithImage

-initWithBarButtonSystemItem

-initWithCustomView

第4种方法就是我们添加各种作料的接口，所以今天的主角其它也是它。

2.在UIToolBar上面添加Title

1. UIToolbar *myToolBar = [[UIToolbar alloc] initWithFrame:
2.                                                     CGRectMake(0.0f, 0.0f, 320.0f, 44.0f)];
3. NSMutableArray *myToolBarItems = [NSMutableArray array];
4. [myToolBarItems addObject:[[[UIBarButtonItem alloc]
5.                                                         initWithTitle:@”myTile”
6.                                                         style:UIBarButtonItemStylePlain
7.                                                         target:self
8.                                                         action:@selector(action)] autorelease]];
9. [myToolBar setItems:myToolBarItems animated:YES];
10. [myToolBar release];
11. [myToolBarItems];

setItems传入值或者说items是一个对象数组。

3.在UIToolBar上面添加image

1. [myToolBarItems addObject:[[[UIBarButtonItem alloc]
2.                                         initWithImage:[UIImage imageNamed:@"myImage.png"]
3.                                         style:UIBarButtonItemStylePlain
4.                                         target:self
5.                                         action:@selector(action)]];

4.在UIToolBar上面添加SystemItem

1. [myToolBarItems addObject:[[[UIBarButtonItem alloc]
2.                                         initWithBarButtonSystemItem:UIBarButtonSystemItemPlay
3.                                         target:self
4.                                         action:@selector(action)] autorelease]];

Note:

initWithBarButtonSystemItem初始化：

- (id)initWithBarButtonSystemItem:(UIBarButtonSystemItem)systemItem target:(id)target action:(SEL)action

Defines system defaults for commonly used items.

1. typedef enum {
2.     UIBarButtonSystemItemDone,
3.     UIBarButtonSystemItemCancel,
4.     UIBarButtonSystemItemEdit,
5.     UIBarButtonSystemItemSave,
6.     UIBarButtonSystemItemAdd,
7.     UIBarButtonSystemItemFlexibleSpace,
8.     UIBarButtonSystemItemFixedSpace,
9.     UIBarButtonSystemItemCompose,
10.     UIBarButtonSystemItemReply,
11.     UIBarButtonSystemItemAction,
12.     UIBarButtonSystemItemOrganize,
13.     UIBarButtonSystemItemBookmarks,
14.     UIBarButtonSystemItemSearch,
15.     UIBarButtonSystemItemRefresh,
16.     UIBarButtonSystemItemStop,
17.     UIBarButtonSystemItemCamera,
18.     UIBarButtonSystemItemTrash,
19.     UIBarButtonSystemItemPlay,
20.     UIBarButtonSystemItemPause,
21.     UIBarButtonSystemItemRewind,
22.     UIBarButtonSystemItemFastForward,
23.     UIBarButtonSystemItemUndo,        // iPhoneOS 3.0
24.     UIBarButtonSystemItemRedo,        // iPhoneOS 3.0
25. } UIBarButtonSystemItem;

 

5.在UIToolBar上面添加其它各种控件,最自由意义，最有意思的，我把它放在最后来讲。我们使用initWithCustomView来完成，

这里需要看一下initWithCustomView的定义：

- (id)initWithCustomView:(UIView *)customView

可以看出，它的参数是一个VIEW，所以我们给它的配料要正确哦才行哦，否则，你就等着时间DIDADIDA的流失吧.

A>加一个开关switch：

1. [myToolBarItems addObject:[[[UIBarButtonItem alloc]
2.                                     initWithCustomView:[[[UISwitch alloc] init] autorelease]]
3.                                     autorelease]];

 

B>加一个按钮UIBarButtonItem

1. UIBarButtonItem *myButton = [[[UIBarButtonItem alloc]
2.                                  initWithTitle:@”myButton”
3.                                  style:UIBarButtonItemStyleBordered
4.                                  target:self
5.                                  action:@selector(action)]autorelease];
6. get1Button.width = 50;
7. [myToolBarItems addObject:myButton];

 

C>加一个文本Label

1. UILabel *myLabel = [[UILabel alloc] initWithFrame:CGRectMake(40.0f, 20.0f, 45.0f, 10.0f)];
2. myLabel.font=[UIFont systemFontOfSize:10];
3. //myLabel.backgroundColor = [UIColor clearColor];
4. //myLabel.textAlignment=UITextAlignmentCenter;
5. UIBarButtonItem *myButtonItem = [[UIBarButtonItem alloc]initWithCustomView:myLabel];
6. [myToolBarItems addObject: myButtonItem];
7. [mylabel release];
8. [myButtonItem release];

 

D>加一个进度条UIProgressView

 

1. UIProgressView *myProgress = [[UIProgressView alloc] initWithFrame:CGRectMake(65.0f, 20.0f, 90.0f, 10.0f)];
2. UIBarButtonItem *myButtonItem = [[UIBarButtonItem alloc]initWithCustomView:myProgress];
3. [myToolBarItems addObject: myButtonItem];
4. [myProgress release];
5. [myButtonItem release];

可以加使用initWithCustomView制作各种button，这里就不在这里一个一个在加了。我想你应该也已经掌握了如何添加各种buttonItem的方法了。
