I have an application with a table view that contains 3 sections. Every thing is okay with displaying data, but when i change the device orientation (from portrait to Landscape and vis versa ) an additional number of rows is added to my table View
Indeed, when debugging my Application, i figured out that cellForRowAtIndexPath: is executed every time i rotate the device.
Can some Good person tell me how can i fix that problem ?
Thanks in advance.
As suspected, your issue is that you are adding items to your data source data in the tableView:numberOfRowsInSection: method. Every time the table asks how many rows are in a section, you add more data to the data structures. Remember, the data source methods will be called many different times.
You need to create your data structures once, outside of any of the data source methods. Your data source methods should be read-only with regard to your data structures. They should simple return a count. No other processing should be done in the data source methods.
