I have a uitableview with 50 rows populated from a predefined nsarray.
How can I select multiple the rows with say maximum 3 allowed at a time and show check when selected and remove check when deselected/
I am really new to xcode and any help is much appreciated. Thank you.
Your data needs to keep track of whether it is selected or not.
Two common ways are: each object in your predefined array has a BOOL that indicates whether or not it is selected, or you keep a second array that holds only references to selected objects. Since you’re limited to three selected, the second option might be better.
When someone selects a cell in your table, you change the selection status of the related object, either switching its BOOL or adding/removing it in the extra array. This is also the place to check whether you already have as many selections as you allow. If selections have changed, you then tell your table to reload data.
In
cellForRowAtIndexPath:you check whether or not the object is selected and mark it accordingly.
