The success of Apple’s iPhone, iPad, and other smartphone devices boost up iOS App Development and make it larger than life in the past few years. Today, more ‘n’ more professionals and technical experts are getting into iOS application development to showcase their creativity and programming skills by making unusual apps for tiny handheld devices like iPhone, iPad, iPod touch, etc.
Developing iOS devices is not the kid’s play, and even experienced iOS developers often make some critical mistakes while developing applications for iOS devices. One of those critical mistakes is iOS memory mistakes, which many novice iOS App developers often commit while designing and developing applications. Such mistakes are highlighted below to aware upcoming iOS developers to avoid such crucial iOS memory mistakes.
Many developers often forget to include dealloc method in each class, which cause memory management problem during iOS development. Therefore, always make appropriate dealloc method in each class to avoid memory management issues.
Also, many time developers never call super dealloc method from dealloc, which later on crash the memory and cause serious issues in your app development. So just remember that you can’t directly call any dealloc method, you must first call the super dealloc method, which should be only called in your dealloc method.

NSLog Statements are very helpful during debugging of the app, but overuse of it could slow down the app’s performance. In addition, the more you use NSLog statements within your app, the more memory it will consume, and in the end, you may get a memory warning from your app itself. So, try to avoid making such mistakes and try to bypass NSLog statements if you really don’t need them.
Underestimating the iOS debugging commands! New iOS developers are often not aware of the power of iOS debugging tools and never consider them during their app development. NSDebugEnabled, MallocStackLogging, and other environment variables could help you out to identify the causes for the crash and all. So, try to get familiar with iOS debugging commands and incorporate them within your app development to avoid memory crashes.
Apart from the above major memory mistakes, many developers often forget to set pointers to nil after releasing, using retain count of the objects, which cause serious memory issues later on.
So, these are some crucial iOS memory mistakes iOS App Developers should avoid during their iOS application Development.
