Why should you use CocoaPods?

This blog post has the intention to show to beginners the tool called CocoaPods, if you’re already familiar with it you may find it boring because I’ll probably show you something you already now.

What’s CocoaPods?

“CocoaPods is a dependency manager for Swift and Objective-C Cocoa projects. It has over 37 thousand libraries and is used over 2.6 million apps. CocoaPods can help you scale your projects elegantly.”(CocoaPods)

If you’re familiar with Rails, you may remember the Gemfile system, and yes, it works just like that. In fact CocoaPods is a gem for Ruby. You can contribute for the project by sending a pull request on the official repository.

 

The advantages of using CocoaPods

You are ready to develop your first iOS project, you’re full of ideias, at first having a dependency manager seems to be pretty not necessary, but remember, you app won’t be the same after every update, in fact, if you’re planning to build the next successful app, you may need starting worrying about how to organize it, this where CocoaPods comes in.

Managing a project dependencies by hand it is not the best ideia, actually, it is a terrible idea, imagine having a project with 50 dependencies and having to update all of them ? Scary huh ? That’s the reason you need a project manager, with CocoaPods if you want to update a pod(That’s how a dependency is called in CocoaPods, like a gem in Ruby) you just need to type:

pod update the_name_of_the_pod

and it will do all the work for you, after that you just need to recompile your project on XCode, and that’s all.

Another reason to use CocoaPods is: a lot of big companies are using it, like Facebook , Google and many others.

You have a lot of support, there are thousands of apps using it, and Stackoverflow if full of questions about it.

iOS – How to round the corners of a button

In this post I’m going to cover how to round the corners of a button in iOS.

I’ve seen a lot of solutions for this, but I found a really simple one.

First of all, you need to select the button and then go to the Object Inspector and click on the + button, then you need to create the keypath: layer.cornerRadius type as a number, then add the value 4 or the value you want as shown below.

After that you can run your app and see the result.

PS: you can only see the result when running the app

That’s all for today. See you in the nexts posts

How to send Push Notifications from a Mac OS X – Push Robot

Mobile Developers love to imagine the users of their apps using the app all day. Push notifications allows developers to reach their users and perform small tasks even when users aren’t actively using an app.

Google has created Firebase Cloud Messaging for helping developers sending Push Notifications to their apps. You just need to login to your Google account and after some setup, you can easily send push notifications. What if you could send notifications from your Mac ? With this in mind, I’ve decided to create a Mac OS X App called Push Robot.

Push Robot allows you to send Push Notifications to your apps using FCM, all you need is the Server Key and the Topic or Device’s Token(to send push notifications to a single app).

Screen Shot 2017-04-12 at 07.54.21

To get the Server Key:

  1. click the settings icon/cog wheel next to your project name at the top of the new Firebase Console
  2. Click Project settings
  3. Click on the Cloud Messaging tab
  4. The key is right under Server Key

Now you can send a push notification to a topic which can reach millions of users or for specific users using the device’s token.

5. Create an action called playMusic like the picture below:

6. Open your ViewCotroller.h to create a property called myStreaming(you should create this property as strong, if you don’t do this the streaming will stop after 2 seconds)

Captura de Tela 2015-12-01 às 22.35.41

7. Now go to your ViewController.m and inside the method playMusic you should call the property you defined in your h file.

The First thing you need to have is the streaming URL (shoucast’s urls should have the address and the port), then your need to init the streaming property, after that you should define the source type, in our case is streaming, after all you just need to set shouldAutoPlay to NO and prepare to play the streaming and finally play.

– (IBAction)playMusic:(id)sender {    

 NSURL *myUrl = [NSURL  URLWithString:@”http://colinawebradio.com.br:9986″];

 self.myStreaming = [[MPMoviePlayerController alloc] initWithContentURL:myUrl];

  self.myStreaming.movieSourceType =         MPMovieSourceTypeStreaming;

   self.myStreaming.shouldAutoplay = NO;

   [self.myStreaming prepareToPlay];

   [self.myStreaming play];

}

After all, run your app and listen to the radio 🙂

That’s all, thanks :).
