分段控件UISegmentedControl

分段控件UISegmentedControl繼承與UIControl

    UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] initWithItems:@[@"所有商家", @"優惠商家", @"個人"]];
    segmentedControl.center = CGPointMake(182, 45);
    
    // 每一個segment的大小默認平分整個segmentedControl的大小，若是把apportionsSegmentWidthsByContent設置爲YES，會根據內容來分配每個segment的大小。
    segmentedControl.apportionsSegmentWidthsByContent = YES;
    
    // 設置當前選中segment下標
    segmentedControl.selectedSegmentIndex = 1;
    
    // 選中瞬間有效果，以後沒有，恢復（不怎麼用）
    // segmentedControl.momentary = YES;
    
    // 字體顏色
    segmentedControl.tintColor = [UIColor orangeColor];
    // segmentedControl.frame = CGRectMake(10, 30, 345, 30);
    
    // 給segmentedControl添加事件
    [segmentedControl addTarget:self action:@selector(doTapSegmentedControl:) forControlEvents:(UIControlEventValueChanged)];
    
    [self.view addSubview:segmentedControl];
    [segmentedControl release];
