    NSArray *segmentedArray = [[NSArray alloc]initWithObjects:@"訊息",@"連絡人",@"群發",@"討論群組",nil];    //初始化UISegmentedControl    UISegmentedControl *segmentedControl = [[UISegmentedControl alloc]initWithItems:segmentedArray];    segmentedControl.frame = CGRectMake(1.0, [UIScreen mainScreen].bounds.size.height-50-64, 318.0, 50.0);    segmentedControl.selectedSegmentIndex = 0;//設定預設選擇項索引    [segmentedControl setBackgroundImage:[UIImage imageNamed:@"zyyy_choose_middle.png"] forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];    [segmentedControl setBackgroundImage:[UIImage imageNamed:@"zyyy_choose_middle_touch.png"] forState:UIControlStateSelected barMetrics:UIBarMetricsDefault];    segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;//設定樣式    [segmentedControl addTarget:self action:@selector(segmentAction:)forControlEvents:UIControlEventValueChanged];  //添加委託方法    [self.view addSubview:segmentedControl];-(void)segmentAction:(UISegmentedControl *)Seg{        NSInteger Index = Seg.selectedSegmentIndex;        NSLog(@"Index %i", Index);        switch (Index) {                    case 0:            break;    }}
