iPhone UITableView创建分区

我试图在UITableView中创建更多的部分，但我似乎无法理解。我希望将“查看完整网站”和“视频”链接移动到自己的部分，并将这些单元格的高度更改为75。我可以创建一个新单元，但我不知道如何正确定位它

    typedef enum { SectionHeader, SectionDetail } Sections;
    typedef enum { SectionHeaderTitle, SectionHeaderDate, SectionHeaderURL,            SectionHeaderEnclosure } HeaderRows;
    typedef enum { SectionDetailSummary } DetailRows;

    @implementation MediaDetailTableViewController

    @synthesize item, dateString, summaryString, teachings;

谢谢你的帮助

您应该从更改

UITableView

的数据源中的适当方法开始

从代码中，您需要将其更改为以下内容：

typedef enum { SectionHeader, SectionMiddle, SectionDetail } Sections;

#pragma mark -
#pragma mark Table view data source

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    // Return the number of sections.
    return 3;
}


- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section    {
    // Return the number of rows in the section.
    switch (section) {
        case 0: return 2;
        case 1: return 2;
        default: return 1;
    }
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    // snip
    switch (indexPath.section) {
        case SectionHeader:
           // snip
           break;
        case SectionMiddle:
           // snip
           break;
        case SectionDetail:
           // snip
           break;
    }
}

使用

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
// Return the number of sections.
return 3;
}
