Memory issues
One: Cell phone memory capacity
- The latest Apple phone iphone6s (plus) now has 2GB of running memory.
- IPhone5, IPhone5S, and IPhone6 (plus) run memory at 1GB.
- IPhone4 and Iphone4s run memory at 512MB.
Two: App running memory
- It is recommended not to exceed 10M. If the user only runs a program memory is used can be around 30M.
- But the odds are almost impossible.
- Generally more than 10M will be memory warning L1 system will kill some of the unused view
Test results of foreign Daniel
So it turns out if you allocate (and use!) around 46-50 MB in your iPhone application it'll just get terminated.
How to keep memory (running) occupied not too high?
- 1. Tableviewcell in the icon image to be trimmed, do not put those 1M or so images directly from the web side to transfer over
- 2. Some of the more deep, or more loop code block, as far as possible in the outer layer autorelease pool, after execution directly [pool drain]
- 3. TableView cell must be reuse, other similar view to reuse.
