Xcode IOS高级链接UITableView

Question

I have developed a Tabbed Style Application in Xcode. I have run into a complication.

I am happy with my progress, But in Pic 2 or Scene 2 or SelectedCellViewController.m I don't want to see all the table cells like in Pic1 or Scene1 Below. I only want to see one table cell and the relevant table cell to link to Pic 3 or Scene 3.

You can choose a table cell in Pic 1 or Scene 1, Then you can see a pic of that color you picked and i will include some info beneath the picture. Now you can see in Pic 2 or Scene 2 there are multiple Table Cells beneath the picture. I only want to show the Relevant Table Cell so you see a larger version, I have already coded the functionality but I am confused how to get rid of the rest of the cells in Pic 2 or Scene 2.

I'm not to sure how to do this, Any help would be much Appreciated.

Answer 1

Your tableView has as many rows as there are values in sitesArray . If there is only one value, or if you change numberOfRowsInSection , you will get a table with one row.

// Return the number of rows in a section
- (NSInteger)tableView:(UITableView *)table numberOfRowsInSection:(NSInteger)section {
    return 1;
}
