Today people are crazy about Smartphone and its applications. Each Smartphone users looking for applications, which are attractive and easy to use. It’s very easy to demand for such an applications but in other side of coin its very hard to develop such an application. When you think from developer prospects, you need to keep many things in mind during iOS application development for any device.  Here are some tips, which should be adopted in your apps to make application better in compare to others. These topics are going to cover.

Ways To Improve iOS Application Performance

A) Application First Launch:
Launch application in such a way that it shows main screen very quickly even if it has images that load from server. Use Asynchronous methods to load data, which are heavy and needs to download from server. Never use giant XIB or Nib, which will freeze application at launch time.  Giant Nib can make your application slow. It’s better to use storyboard for apps that are targeting iOS5 and later. You can also break into discrete Nibs for apps targeting iOS 4.x or later. Avoid using intiwithNibName method to load large images. You can use viewDidLoad to achieve it.

B) Application Workflow:
Normally an application shows messages to inform or warn users. Frequently showing alerts and messages will create negative impress to end-user. Alerts will interrupt application flow and divert user’s concentration from application. Developer also take care that inappropriate message should not be appear, it annoys the users. Even though alerts and messages represent small amounts of text don't show them repeatedly without any strong reason.

C) Appplication Responsiveness: 
How you fill if you have to wait for long time for response of your action? It's irritating. Right. There are so many thing happens in iOS application development and in mobile application which takes time to give you expected result e.g Parsing data, fetching data from server, sending data to server etc. Mostly mobile application takes time to communicate with server. So it’s advisable to cancel unrequited connections, cached data for later use and Incremental process data instead of loading it at once.

All application has images to make application more attractive and jazzy. It’s recommended to use PNG format for images instead of JPG as Xcode will optimize it for application. Use tiled image for Patten. Also cache your image data using NSCache. It helps your application to show any large images very quickly.

Memory is always impact on responsiveness of any mobile application. For viewing list in mobile application developer use table. Its very common practice. Its very important to check memory consumption done by table while table has many data and user needs to scroll it to view data. Its better to check memory usage of table view via instrument and optimized it if it cause issues. Don't write code, which uses more CPU. Best practice is to reuse table view cell to overcome with slowness issue.
