IOS ——UI篇—— UISegmentedControl的用法總結

 

 

 

 //第一種創建方式
    UISegmentedControl *seg = [[UISegmentedControl alloc]initWithItems:@[@"1",@"2",@"3"]];
    seg.frame = CGRectMake(40, 100, 60, 20);

    [seg insertSegmentWithImage:[UIImage imageNamed:@"圖片名"] atIndex:4 animated:YES];//給某一段設置圖片（圖片為帶邊框透明的才可以完整顯示，其它圖片不能完整顯示）
 UIImage *image =  [seg imageForSegmentAtIndex:2];//獲取某一段的圖片
     NSLog(@"圖片：%@",image);
     NSString *str = [seg titleForSegmentAtIndex:1];//獲取某一段的標題
    NSLog(@“第幾個：%zi",segment.selectedSegmentIndex);//獲取當前點擊的編號
     NSLog(@"標題：%@",str);
    [seg setWidth:100 forSegmentAtIndex:1];//設置某一段的寬度
    [seg setEnabled:YES];//設置整體是否被激活；
    [seg setEnabled:YES forSegmentAtIndex:2];//設置某一段是否激活
    seg.selectedSegmentIndex = 1;//設置某段為默認選中項
    NSLog(@"%zi",seg.selectedSegmentIndex);//獲取當前被選中的段；
    seg.tintColor = [UIColor purpleColor];//設置邊框和選中顏色；
    [seg setBackgroundImage:[UIImage imageNamed:@"圖片名"] forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];//設置整體的背景圖片

    //綁定監聽事件
    [seg addTarget:self action:@selector(方法名:) forControlEvents:UIControlEventValueChanged];
    [self.view addSubview:seg];

    //第二種創建方式
    UISegmentedControl *seg2 = [[UISegmentedControl alloc]initWithFrame:CGRectMake(40, 120, 60, 20)];
    [seg2 insertSegmentWithTitle:@"1" atIndex:1 animated:YES];
    [seg2 insertSegmentWithTitle:@"2" atIndex:2 animated:YES];
    [seg2 removeSegmentAtIndex:1 animated:YES];//移除某段
    NSLog(@"%zi",seg2.numberOfSegments);//獲取段數
    [self.view addSubview:seg2];

}

-(void)mySwitch
{
    UISwitch *swi = (UISwitch *)[self.view viewWithTag:1];
    NSLog(@"%d",swi.isOn);

}
