I am trying to create more sections in my UITableView and I cannot seem to figure it out. I am looking to move the "View full website" and "Video" links into their own section and change the height of those cells to 75. I can create a new cell, but I cannot figure out how to position it properly.

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

iPhone UITableView Create Sections

Thank you for all your help!


You should start by changing the appropriate methods in the UITableView's data source.

From your code, you would need to change it to something like this:

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;
    }
}


Use

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