The success of Apple’s iPhone, iPad and other smart phone devices boost up iOS App Development and make it larger than life in the past few years. Today, more ‘n’ more professionals as well as technical experts are getting into iOS application development to showcase their creativity and programming skills by making unusual apps for tiny hand held devices like iPhone, iPad, iPod touch etc.
Developing apps for iOS devices is not the kid’s play, and even the 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 in order 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. Always make appropriate dealloc method in each class to avoid memory management issues.
Also it happens that many time developers never call super dealloc method from dealloc, which later on crash the memory and cause serious issues in your app development. Just remember that you can’t directly call any dealloc method, you must first call super dealloc method and that 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 performance of the app. The more you use NSLog statements within your app, the more memory it will consume and at the end you may get 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 about 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 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 above major memory mistakes, many developers often forget to set pointers to nil after releasing, using retainCount 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.
