为UIToolBar工具条添加各种各样的UIBbarButtonItem

1.首先，我们看一下UIBbarButtonItem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UIBbarButtonItem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

 

 

 UIToolbar *myToolBar = [[UIToolbar alloc] initWithFrame:
                                                     CGRectMake(0.0f, 0.0f, 320.0f, 44.0f)];

 NSMutableArray *myToolBarItems = [NSMutableArray array];
 [myToolBarItems addObject:[[[UIBarButtonItem alloc]
                                                         initWithTitle:@"myTile"
                                                         style:UIBarButtonItemStylePlain
                                                         target:self
                                                         action:@selector(action)] autorelease]];
 [myToolBar setItems:myToolBarItems animated:YES];
 [myToolBar release];
 [myToolBarItems];

 

 

setItems传入值或者说items是一个对象数组。

 

3.在UIToolBar上面添加image

 

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

 

 

4.在UIToolBar上面添加SystemItem

 [myToolBarItems addObject:[[[UIBarButtonItem alloc]
                                         initWithBarButtonSystemItem:UIBarButtonSystemItemPlay
                                         target:self
                                         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.

 typedef enum {
     UIBarButtonSystemItemDone,
     UIBarButtonSystemItemCancel,
     UIBarButtonSystemItemEdit,
     UIBarButtonSystemItemSave,
     UIBarButtonSystemItemAdd,
     UIBarButtonSystemItemFlexibleSpace,
     UIBarButtonSystemItemFixedSpace,
     UIBarButtonSystemItemCompose,
     UIBarButtonSystemItemReply,
     UIBarButtonSystemItemAction,
     UIBarButtonSystemItemOrganize,
     UIBarButtonSystemItemBookmarks,
     UIBarButtonSystemItemSearch,
     UIBarButtonSystemItemRefresh,
     UIBarButtonSystemItemStop,
     UIBarButtonSystemItemCamera,
     UIBarButtonSystemItemTrash,
     UIBarButtonSystemItemPlay,
     UIBarButtonSystemItemPause,
     UIBarButtonSystemItemRewind,
     UIBarButtonSystemItemFastForward,
     UIBarButtonSystemItemUndo,        // iPhoneOS 3.0
     UIBarButtonSystemItemRedo,        // iPhoneOS 3.0
 } 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：

 [myToolBarItems addObject:[[[UIBarButtonItem alloc]
                                     initWithCustomView:[[[UISwitch alloc] init] autorelease]]
                                     autorelease]];

 

 

B>加一个按钮UIBarButtonItem

 UIBarButtonItem *myButton = [[[UIBarButtonItem alloc]
                                  initWithTitle:@"myButton"
                                  style:UIBarButtonItemStyleBordered
                                  target:self
                                  action:@selector(action)]autorelease];
 get1Button.width = 50;
 [myToolBarItems addObject:myButton];

 

C>加一个文本Label

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

 

 

 

D>加一个进度条UIProgressView

 

 UIProgressView *myProgress = [[UIProgressView alloc] initWithFrame:CGRectMake(65.0f, 20.0f, 90.0f, 10.0f)];
 UIBarButtonItem *myButtonItem = [[UIBarButtonItem alloc]initWithCustomView:myProgress];
 [myToolBarItems addObject: myButtonItem];
 [myProgress release];
 [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。
