Question

A strange problem occured when i build my code on iOS5 which was properly working on 4.2.

The problem was with the tableview indexpath. I was trying to get the indexpath value in another method of same class which resulted in a crash in iOS5.

After 2 hours i manage to get it solve by making some changes which i thought to share.

.h file

NSIndexpath *indexPathValue;

@property(nonatomic, copy) NSIndexpath *indexPath;

.m file method cellForRowAtIndexPath

self.indexPathValue = indexPath;

And used the indexPathValue instance wherever required. Hope this help.

Answer 1

The property can have the retain attribute, not the copy attribute; it will work fine as long as you remember to use the setter method whenever you wish to assign it:

self.indexPathValue = indexPath;

Your current code copies the pointer without attempting to retain it in any way (you don’t use the synthesized setter method) and it will cause a crash some time later.
