Ipad App Development Challenges-fkzww

Software iPad is an innovative device and attracts many to use it frequently, but naturally it has huge market so there are many takers of iPad app development. Now a day there is huge demand of iPad applications and every developer has dream of be.ing an iPad app developer. In practice many developers are familiar with either .. or Java so the first challenge they face is to cope with an alien that is Objective C. language which inherits the characteristics of her parents C or C++ but have some unique syntax as well which is quite peculiar. Second challenge is to learn Mac system. You should be familiar with Mac if you want to develop iPad application because iPad app development is not possible with Windows or Linux. You are to invest in Mac system and software this again increase the overall development cost. Oppose to desktop iPad has low memory so an iPad application developer should make sure that memory utilization of the app should be controlled such a way that the memory warnings could be avoided at any cost. This again needs proper handling because if any point of time, the OS sends memory warning signals to the app and didReceiveMrmoryWarning method is invoked, releasing the resources with low priority should be ensured to prevent the app from being closed by the OS. The way out from this problem is that the lazy loading technique should be used on all the view so that application is not closed in case of low memory. Unlike Java and .. in Objective C, the object that is allocated needs to be de-allocated by the developers this increase coding and hence the burden over the developers. You have to consider proper timing while releasing any object because you couldnt re-access the object once released otherwise the application would crash. Memory leak is a challenge. To check the possible memory leaks there is a tool available in the x-code- (Run > Start with Performance Tool > Leaks). Assure that there should be no memory leak left before shipping the application. If the application is re-opened after closing, it should restore the last state. This is a challenge for the iPad app developers. This was prominent before emergence of iOS 4 so this feature was highly unavoidable from the usability point of view. Even though, now the application resides in memory unless manually closed, but this feature is still required. About the Author: 相关的主题文章:
