iphone - 如何使 UISegmentedControl 像 UITabBarController 一样工作？

Question

如何在选择不同的段时使用 UISegmentedControl 加载不同的 subview ？我是 Objective-C 和 iOS 编程的新手。

或者有没有办法让 UITabBarController 看起来像 UISegmentedControl？

Answer 1

对于程序化方法

在加载 View 中:

{
    NSArray *segments = [NSArray arrayWithObjects:@"Left", @"Right", nil];


    segmentedControl = [[UISegmentedControl alloc]initWithItems:segments];
    [segmentedControl addTarget:self
    action:@selector(changeSubViews)
    forControlEvents:UIControlEventValueChanged];
    contentView = [UIView alloc]initwithFrame:(the frame where you want the subViews to be displayed)];
    [self.view addSubView:contentView];

    }

    - (void)changeSubViews
        {
            switch(segmentedControl.selectedSegmentIndex)
            {
            case 0:
                {
                    [rightView removeFromSuperView];
                    if (leftView ==nil){leftView alloc, init;}
                    [contentView addSubView:leftView];
                    break;
                }
            case 1:
                {
                    [leftView removeFromSuperView];
                    if (rightView ==nil){rightView alloc, init;}
                    [contentView addSubView:rightView];
                    break;
                }
            }
    }
