Healthy iOS Development Tips & Tricks

About iOS Development:

Being an iOS developer always feels exciting because it gives us a chance to work with & to do innovative things. There is always a scope for something new depends on developer capabilities & level of thinking.

But at the same time, it also has challenges in the application development like to compatible with latest iOS versions & at the same time should also work on lower versions as well. We also need to keep in mind about future iOS versions as well to make sure easy adaptability. In short, it should have always a scope for the future aspects.

Quick & Easy Tips that Should Help you

Design :

Use app thinning concept & create image sets into .xassets files only. Don’t directly put images into resource folder. Using .xassets applies app thinning & also allows image compression so it makes sure the archive file size will not get much affected by a large number of images.

App Icon / Launch screen & other graphical elements used in the application must not be size beyond 1 mb. Make sure all images are of few kb. Preferably 10-20 kb size of images makes app runs smoothly. If you find any image size of around 500 kb or more than 1 mb contact designer immediately & tell them to compress the image file & make it small size. There are lots of online tools available which allows compressing images without even designer help. Some of the good online tools are :

  2. http://compressimage.toolur.com
  3. http://compressjpeg.com
  4. http://jpeg-optimizer.com

Right now 1 images are not getting used any more on iPhone devices. So there is no mean to add 1x images into .xassets folder. So you can keep it empty. That will reduce the number of images in the application so overall it will help to reduce the size of an application.

Keep removing unnecessary & unused images from an application. Sometimes it happens that large scale application has always keep updated with new graphics & adding/Removing features on the app. So at the time developer often forgets to remove old or unused images from the application. That files increases the application size & also downs the performance of the application as well. So it becomes necessary to keep cleaning unused files from the application.

Development:

Always prefer to with ARC based on iOS Development. That will reduce the half of your work to reduce the memory usage

Keep removing unnecessary third-party libraries & classes that are not currently in use for the application. That will improve compilation time & improves app performance

Less Usage of nib files. That will always increase the memory load. Always prefer to add view controllers into a storyboard

Make sure storyboard does not load with too many controllers. That increases compile time of the application

Make View controller as light as possible as because too many controls added into view controller makes it slow in appearance. Make dynamic controls which are less in use. That will make view controller light in storyboard

“Simplicity is the best virtue”, That quote has always been a truth in iOS development. The more simplified code will less the complexity.

Use standard naming convention. It’s nothing but you need to keep in mind one thing that variable, methods or file whatever you create must be present their characteristics. For eg: you are taking string variable to store name then you should name it like “strName”

Use @autoreleasepool where arc doesn’t work or any major operations where you think causing the memory issues you can write that code inside @autoreleasepool. So what it will ensures that the relevant objects will be released just after the end of operation completion.

See example :

@autoreleasepool {
sourceTile.origin.y = y * sourceTileHeightMinusOverlap + sourceSeemOverlap;
destTile.origin.y = destResolution.height – (( y + 1 ) * sourceTileHeightMinusOverlap * imageScale + kDestSeemOverlap);
sourceTileImageRef = CGImageCreateWithImageInRect( sourceImageRef, sourceTile );
if( y == iterations – 1 && remainder ) {
float dify = destTile.size.height;
destTile.size.height = CGImageGetHeight( sourceTileImageRef ) * imageScale;
dify -= destTile.size.height;
destTile.origin.y += dify;
}
CGContextDrawImage( destContext, destTile, sourceTileImageRef );
CGImageRelease( sourceTileImageRef );
}

Find & resolve memory level warnings. Try to check the memory usage & CPU usage time by while navigating from one to another view controllers. That will give the rough idea about which view controller causing high memory usage so you can take appropriate actions on that page. For more detailed information like which line exactly causing memory leaks, you can use memory tools available with Xcode.

Use Pragma Symbols in a code to separate the functions.

Create classes & increase reusability of methods & functions. That will help to reduce compilation time by not to compile same functions again & again.

Remove Breakpoints, NSLogs once your purpose of it done. Also, remove commented & unused methods. That adds complexity to the project & increases development time.

Use dispatch_async function while performing UI operations through programming. This is a very common issue & makes application become unresponsive sometimes while performing UI operations & at the same time some another process blocks it. That results in bad user experience & user might leave the application in that case.

See example :

dispatch_async(dispatch_get_main_queue(), ^{
[self.collectionView reloadData];
});

Conclusion:

By following above tips developer not only can develop & maintain high quality apps but also helps to make a seamless experience & make a user more active on the application. That helps to make application analytics stronger & it directly effects to improve app ranking on the store.
