【开发笔记】 UISegmentedController 控件使用

效果图：

代码：

    NSArray *segmentTextContent = [NSArray arrayWithObjects: @"Check", @"Search", @"Tools", nil];
    UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] initWithItems:segmentTextContent];
    
    CGRect frame = CGRectMake(50, 100,self.view.bounds.size.width - (50 * 2.0),40);
    segmentedControl.frame = frame;
    [segmentedControl addTarget:self action:@selector(segmentAction:) forControlEvents:UIControlEventValueChanged];
    segmentedControl.segmentedControlStyle = UISegmentedControlStyleBordered;
    segmentedControl.selectedSegmentIndex = 1;
    
    [self.view addSubview:segmentedControl];
    [segmentedControl release];

2.UISegmentedControl 放在 UIToolBar上面

效果图：

代码：

　　NSArray *array = @[@"列表",@"日",@"月"];
    UISegmentedControl *modePicker = [[UISegmentedControl alloc]initWithItems:array];
    modePicker.segmentedControlStyle = UISegmentedControlStyleBar; 
    
    [modePicker setWidth:50 forSegmentAtIndex:0]; 
    [modePicker setWidth:50 forSegmentAtIndex:1];
    [modePicker setWidth:50 forSegmentAtIndex:2];
    
    NSString *todayTitle = @"今天";
    UIBarButtonItem *todayButton = [[UIBarButtonItem alloc] initWithTitle:todayTitle style:UIBarButtonItemStyleBordered target:self action:@selector(todayButtonTapped:)];
    UIBarButtonItem *item = [[UIBarButtonItem alloc] initWithCustomView:modePicker];

　　[modePicker release]

　　UIBarButtonItem *fixedSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil]; [fixedSpace setWidth:20];
 [self setToolbarItems:@[todayButton, fixedSpace, item] animated:NO]; 
　　[[self navigationController] setToolbarHidden:NO animated:NO];

　　[todayButton release];
　　[item release];
　　[fixedSpace release];
