I have a NSMutableArray in which I m storing items taken from service url and done parsing.I m showing the array items in UITableView acting like gridview(4 columns in each row and no of rows depends on array count).It is something like showing all the online exam slots available in a week.So I have to load each day timings one by one and if all the slots are reserved for a particular day then should display a msg for that day (No slot available) and then load the next array items in a tableView. But I m able to get only the last day slots available.
I have to get in the following format:
10/1/2013
10:00 AM 11:00 AM 12:00 PM 1:00 PM
2:00 PM
11/1/2013
11:00 AM 12:00 PM 1:00 PM 2:00 PM
12/1/2013
No slot available
13/1/2013
10:00 AM 11:00 AM 12:00 PM 1:00 PM
2:00 PM 3:00 PM
............
As of now I m using a same tableview and loading each array items for a particular day seprately.But I m able to get only the last day timings
How can I get in this particular format?
Any suggestions/advices would be appreciable on which control to use or how to use the same tableView would be appreciable.

This is the code I have done .
try the some code from my this bellow code… remove some other code which not useful for you..
i had this type of requirement and i complete it with my bellow code and logic… also see the image i think you want something like that…
See the screen shot which output of this code…
Also See these bellow links for
UIGridViewDemo and tutorials..UIGridView
GMGridView
i hope this helpful to you…
