I have a plist file. I want to delete the data from the plist. How can I do it programmatically ?

My Plist have an array cells. cells is filled by dictionaries . Each dictionary is filled by string.

I used the following way.

    NSString* plistPath1 = [[NSBundle mainBundle] pathForResource:@"details" ofType:@"plist"];

[cells removeObjectAtIndex:[clickedButtonPath row]];
    NSMutableArray *array1 = [[NSMutableArray alloc] initWithCapacity:4];
array1 = cells;
   [array1 writeToFile:plistPath1 atomically: YES];  

But the plist is not taking the changes.

Thank you.
