iphone - 我想在 UItableview 中隐藏页脚视图

Question

我有一个段控制。当我单击一个段时，我想显示 FooterView，而当我单击第二个段时，我想隐藏 FooterView。

Answer 1

NSArray *itemArray = [NSArray arrayWithObjects: @"One", @"Two", nil];
UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] initWithItems:itemArray];
segmentedControl.frame = CGRectMake(35, 200, 250, 50);
segmentedControl.segmentedControlStyle = UISegmentedControlStylePlain;
segmentedControl.selectedSegmentIndex = 1;
[segmentedControl addTarget:self action:@selector(ButtonPress:) forControlEvents:UIControlEventChanged];
[self.view addSubview:segmentedControl];
[segmentedControl release];

- (void)ButtonPress:(id)sender 
{
    if([sender selectedSegmentIndex] == 0)
    {
        //put your code as per condition
        footerView.hidden = FALSE;
    } else {
        //put your code as per condition
        footerView.hidden = TRUE;
    }
}
