iOS開篇——UI之UISegmentedControl (分段選擇器)

建立分段選擇器

UISegmentedControl * sc = [[UISegmentedControl alloc]initWithFrame:CGRectMake(50, 100, 200, 30)];
    
    [sc insertSegmentWithTitle:@"第一頁" atIndex:0 animated:YES];
    [sc insertSegmentWithTitle:@"第二頁" atIndex:1 animated:YES];
    [sc insertSegmentWithTitle:@"第三頁" atIndex:2 animated:YES];
    
    [sc addTarget:self action:@selector(onClick:) forControlEvents:UIControlEventValueChanged];

    [self.view addSubview:sc];       

實作點選方法

- (void)onClick:(UISegmentedControl *)sc {
    if (sc.selectedSegmentIndex == 0) {
        [sc removeSegmentAtIndex:0 animated:YES];
    }else if(sc.selectedSegmentIndex == 1){
        [sc insertSegmentWithTitle:@"禮拜" atIndex:0 animated:YES];
    }
}
//根據傳來的sc的index值判斷執行的方法
