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。
