I’ll have a look, because it is a bit of a retrograde step to get rid of ARC
now that I’ve gone to all the trouble of converting it.
I found using retainCount in conduction with some overrides worked wonderfully
for me, but I’ll have a go using instruments. One of the things that I can’t
seem change is that whenever I run the Profile, it selects an iPad retina
instead of a normal iPad which takes up the while screen. I’ll have another go
and try to get it to work on the normal iPad.
Here is an extract of one of the methods I suspect of being the root cause. I’m
wondering if something is wrong with the wat the Code Block works. I haven’t
changed that bit, just made it ARC (which is why you will see some releases
commented out). Also, when I did this, I left the property attributes as
“retain” and “assign”, I’m wondering if it would be better to change them to
“strong” and “weak” ? Although, AFAIK this shouldn’t make a difference?
