On January 28th, 2016, terrible news for the developer who are using Parse for their app’s back end. They have announced that Parse service and Parse will be fully shutting down next year i.e. January 28th, 2017.
As parse will be shutting down their service, we need to find the Parse alternatives or have to write our own backend. For individual developer like me, to write the backend for my mobile app and to host on server is not possible. So, I have started out searching for the Parse alternative for my iOS mobile app and I have found the following list on github.
Check out Parse alernatives: https://github.com/milanpanchal/ParseAlternatives
Comment out your favourite Parse alternative. 🙂
With the launch of iOS 9, Apple added a new level of security for communication of app and its web services. If you are creating any connection using NSURLConnection or NSURLSession in iOS 9 then you will need to use “App transport security (ATS)”, which will reject any insecure connections.
iOS 9 released has “App Transport Security” which encourages developers to use https instead of http.
App Transport Security has blocked a cleartext HTTP (http://) resource load since it is insecure. Temporary exceptions can be configured via your app’s Info.plist file.
To ignore all app transport security restrictions, add following key in your app’s Info.plist file.
<key>NSAppTransportSecurity</key> <dict> <!--Include to allow all connections (DANGER)--> <key>NSAllowsArbitraryLoads</key> <true/> </dict>
Also, You can add exceptions for specific domains in your Info.plist:
<key>NSAppTransportSecurity</key> <dict> <key>NSAllowsArbitraryLoads</key> <false/> <key>NSExceptionDomains</key> <dict> <key><!-- your_remote_server.com / localhost --></key> <dict> <key>NSIncludesSubdomains</key> <true/> <key>NSExceptionAllowsInsecureHTTPLoads</key> <true/> <key>NSExceptionRequiresForwardSecrecy</key> <true/> </dict> <!-- add more domain here --> </dict> </dict>
See Apple’s Info.plist reference for full details
If you have set of images with transparency, and want to remove transparency from all the images?
You can achieve that by simply using imagemagick, by using following command:
$ mogrify -alpha off image-name.png
First of all make sure you have install the imagemagick. If not then install it using following command:
$ apt-get install imagemagick
$ brew install imagemagick --disable-openmp --build-from-source
If you want to remove alpha channel (transparency) from multiple images then, move all images into one folder and navigate to that folder and use the following command:
$ mogrify -alpha off *.png
It's done! Using single command from ImageMagick we removed alpha channel from all PNG images.
You can also check whether Image contain alpha channel or not by running following command:
$ sips -g all image-name.png
Where -g stands for, --getProperty key
I'm sure you will fall in love with ImageMagic as you explore its usage.
To add border to the image or set of images:
$ mogrify -mattecolor black -frame 10x10 image-name.jpg
You can use the same command to apply multiple border to the image(s)
To convert image into gray scale image(s):
$ mogrify -type grayscale image-name.jpg
To resize the image(s):
$ mogrify -resize 50% image-name.jpg
$ mogrify -resize 500x500 image-name.jpg #To maintain the aspect ratio
$ mogrify -resize 500x500\! image-name.jpg #To ignore the aspect ratio
With the release of Xcode6, Apple brought some great improvement to interface builder. With new Xcode6 now you can design custom views via Interface builder. You can achieve live rendering of custom views via IB_DESIGNABLE and IBInspectable attributes.
In this blog, I will give you an overview of IB_DESIGNABLE and IBInspectable attributes. So let’s create a demo project and follow the steps.
Sample code will look like as follow.
#import <UIKit/UIKit.h> IB_DESIGNABLE @interface SAMCustomView : UIView @property (nonatomic) IBInspectable UIColor *startColor; @property (nonatomic) IBInspectable UIColor *midColor; @property (nonatomic) IBInspectable UIColor *endColor; @property (nonatomic) IBInspectable NSInteger borderWidth; @property (nonatomic) IBInspectable CGFloat cornerRadious; @property (nonatomic) IBInspectable BOOL isHorizontal; @end
Currently, IBInspectable support following types.
To support older Xcode you just need to add empty macro for IBInspectable, like so:
#ifndef IBInspectable #define IBInspectable #endif
If you found this useful please take a moment to share this with your friends 🙂

The size limit of an app package submitted through iTunes Connect has increased from 2 GB to 4 GB, so you can include more media in your submission and provide a more complete, rich user experience upon installation. Please keep in mind that this change does not affect the cellular network delivery size limit of 100 MB.
