I'm developing an app for iPhone but it is draining memory to a point where adding text takes about 2 sec per letter. I have a total of 97 viewcontollers on my story board with 54 .h & .m viewcontroller files each. I do reuse some .h & .m files for different views in my storyboard. The problem started when I added the last 4 viewcontollers to the storyboard. With no text/buttons....in them my physical memory went from (total 4gb) 2,04gb to 9,7mb. Deleting the 4 views gave back the memory and all works fine, adding them and I have a problem. The app runs fine in the simulator and on the device with no issues. I've uninstalled XCode and reinstalled - same problem. Please advise.
