iOS UIToolbar的使用

 UIToolbar *myToolBar = [[UIToolbar alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 320.0f, 80.0f)];

    

    NSMutableArray *myToolBarItems = [NSMutableArray array];

    

    [myToolBarItems addObject:[[UIBarButtonItem alloc]initWithTitle:@"myTile"style:UIBarButtonItemStylePlain target:self action:@selector(action)] ];

    

    [myToolBar setItems:myToolBarItems animated:YES];

   //- (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] ]];

    

    //B>加一个按钮UIBarButtonItem

    

    UIBarButtonItem *myButton = [[UIBarButtonItem alloc] initWithTitle:@"myButton"style:UIBarButtonItemStyleBordered target:self action:@selector(action)];

    

    //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];

    

    

    //D>加一个进度条UIProgressView

    

    UIProgressView *myProgress = [[UIProgressView alloc] initWithFrame:CGRectMake(65.0f, 20.0f, 90.0f, 10.0f)];

    

    UIBarButtonItem *myButtonItem1 = [[UIBarButtonItem alloc]initWithCustomView:myProgress];

    

    [myToolBarItems addObject: myButtonItem1];



   // 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。
