First you need to import the AVFoundation framework into your view controller. You will need to add three properties to your view controller: a button for the user to tap to start or stop recording, an audio session to manage recording, and an audio recorder to handle the actual reading and saving of data.

You can create the button in Interface Builder if you prefer; we'll be doing it in code here. Recording audio requires a user's permission to stop malicious apps doing malicious things, so we need to request recording permission from the user. If they grant permission, we'll create our recording button. Put this into viewDidLoad :. I made the code for loadRecordingUI separate so you can replace it easily either with IB work or something else. Here's the least you need to do:. That configures the button to call a method called recordTapped when it's tapped.

Don't worry, we haven't written that yet! Before we write the code for recordTapped we need to do a few other things. First, we need a method to start recording. This needs to decide where to save the audio, configure the recording settings, then start recording.

Here's the code:. That code won't build just yet, because it has two problems. First, it uses the method getDocumentsDirectorywhich is a helper method I include in most of my projects. Here it is:. Second, it assigns self to be the delegate of the audio recorder, which means you need to conform your view controller to the AVAudioRecorderDelegate protocol.

With the code written to start recording, we need matching code to finish recording. This will tell the audio recorder to stop recording, then put the button title back to either "Tap to Record" if recording finished successfully or "Tap to Re-record" if there was a problem.

With those two in place, we can finally write recordTappedbecause it just needs to call either startRecording or finishRecording depending on the state of the audio recorder.

Before you're done, there's one more thing to be aware of: iOS might stop your recording for some reason out of your control, such as if a phone call comes in. We are the delegate of the audio recorder, so if this situation crops up you'll be sent a audioRecorderDidFinishRecording message that you can pass on to finishRecording like this:.

AV Foundation has grown considerably since then, with well over classes now. This tutorial covers media playback and some light editing to get you started with AV Foundation. In other words, you really need to test this code on a device! A free account will work just fine for this tutorial. Start by downloading the materials for this tutorial you can find a link at the top or bottom of this tutorial.

Build and run the project, and test out the buttons; only the three buttons on the initial scene do anything, but you will change that soon! Start by opening PlayVideoViewController. Next, scroll down to the end of the file and add the following class extensions. Make sure you add these to the very bottom of the file, outside the curly braces of the class declaration:. In the code above, you ensure that tapping Play Video will open the UIImagePickerControllerallowing the user to select a video file from the media library.

It does the following:. Build and run. Tap Select and Play Video on the first screen, and then tap Play Video on the second screen, you should see your videos presented similar to the following screenshot. Once you see the list of videos, select one.

If you tap the play button the video will play. However, if you tap the choose button, the app just returns to the Play Video screen! You should be able to see the video playing in the media player.

I love Iphone but when I upload videos on Facebook, it blurs the video. So far so good. Update- I use the paid version for recording my kids High School Basketball and Volleyball games on my iPad and it works great. I then save the video to my photo album for editing. So much easier than having multiple clips to put together.

One major flaw I hope the developer fixes-If you forget to press the red stop button after recording your video, then close the app or close your iPad, you will lose the video.

It would be much better if video was still available even if you forgot to hit stop button. Then when you go back into the app, you can press the stop button to save if you wish. Please fix with an update. Problem Fixed. App crashes when trying to view videos, pause function when paused for 10minutes will lose your video.

I would love to get my money back. Requires iOS Compatible with iPhone, iPad, and iPod touch. App Store Preview. Screenshots iPhone iPad. Jan 20, Version 1. Ratings and Reviews See All.Swift blocks are an increasingly common way of providing callback type behavior to asynchronous functions.

Swift 4. Due to the mechanics of memory management, if we need access to local variable within that block, it must be captured. The Swift compiler automatically manages this for you. Sometimes you don't want this behavior.

Do More with Software

The most common reason why is the case where you need to call a method on self inside the block. The block will retain self and you've just created a bi-directional dependency graph, otherwise known as a retain cycle.

This is bad because it means self can't ever be released as long as the block lives. Often times the blocks are stored as properties on the instance, or as observers for KVO or notifications, and their lifetime is bound to self. To avoid this, you can provide a capture binding declaration to the block definition to influence when a variable should be strongly held or not:.

So unless we strongly reference dog in a property or through some other means, it will fall out of scope, and the dog reference inside the block will be nil. By declaring a capture as weakyou're telling the block to "nil-out" this reference if the original is released.

If you need to guarantee that the items in the block execute you can create a new strong reference inside the block. For instance the variable became nil while the block was executing, preventing some of the behavior from executing. In the above example, we ensure that our strongSelf reference exists for the scope of the block. This avoids some of the weird wording, but it also strikes me as a little odd.

I tweeted about this:. This line is entirely swift keywords I also think lines like the above would be incredibly puzzling for someone brand new to the language. That said, I do think the syntax is a lot cleaner, and I'll probably start using this in my projects. If you've done this, congratulations The Strong-weak dance If you need to guarantee that the items in the block execute you can create a new strong reference inside the block.

This method is fairly common in Swift projects, but always felt a little odd. Back to Swift 4. I tweeted about this: This line is entirely swift keywords What do you think about this change?

Share this.AVFoundation makes audio recording a lot simpler than recording using Core Audio. The first thing you need to do when creating a recorder is to specify the audio format that the recorder will use.

This is a Dictionary of settings. Here are a few settings to record in Apple Lossless format. Then you create the recorder with those settings and the URL of the output sound file.
