[iphone开发私房菜_2_] 为UIToolBar工具条添加各种各样的UIBbarButtonItem
上一道菜是在导航条上面玩乐，今天给大家奉上一道玩乐工具条的私房菜，道我们这里需要把各种控件或者view封装成UIBbarButtonItem，然后添加到UIToolBar上。OK，Let's Do it.

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。
