Question

I m trying to create a similar login/register view as the Tumblr s iPhone app. I want the button to hide the last two rows when clicked, and show them again when clicked again.

任何想法?

感谢

请在<条码>上填写<条码>,然后在您执行<条码>时使用:

// USE THIS if you don t use sections at all
- (NSInteger)numberOfRowsInSection:(NSInteger)section
{
    if(self.hideLastTwoRows)
    {
        return [self numberOfRows]-2; // obviously use the right thing here
    } else {
        return [self numberOfRows];
    }
}

// USE THIS if you do use sections, and the last 2 rows are in the second section
- (NSInteger)numberOfSections
{
    if(self.hideLastTwoRows)
        return 1;
    else
        return 2;
}

我确信,你也可以找到其他方法这样做。 (a) 确保 but也用<代码>(表View reloadData)或采用特定指数途径的类似后载方法重载表。

You can also use following code also

- (NSInteger)numberOfRowsInSection:(NSInteger)section
{
     return [arForData count]-2;

}
