Bugsnag Notifier for iOS

The Bugsnag Notifier for iOS gives you instant notification of exceptions thrown from your iOS applications. The notifier hooks into NSSetUncaughtExceptionHandler, which means any uncaught exceptions will trigger a notification to be sent to your Bugsnag project. Bugsnag will also monitor for fatal signals sent to your application, for example a Segmentation Fault.

Bugsnag captures errors in real-time from your web, mobile and desktop applications, helping you to understand and resolve them as fast as possible. Create a free account to start capturing exceptions from your applications.

Installation & Setup

Include Bugsnag.h and Bugsnag.m in your Xcode project.

Import the Bugsnag.h file into your application delegate.

#import "Bugsnag.h"

In your application:didFinishLaunchingWithOptions: method, register with bugsnag by calling,

[Bugsnag startBugsnagWithApiKey:@"your-api-key-goes-here"];

###JSON Library

The Bugsnag iOS notifier requires a JSON library in order to function. It is able to use the library included in iOS 5 if running on an iOS 5 device. Otherwise it looks for any of the following libraries:

• JSONKit
• NextiveJson
• SBJson
• YAJL

If none of these libraries are present, the iOS notifier will be unable to notify Bugsnag of an error.

Send Non-Fatal Exceptions to Bugsnag

If you would like to send non-fatal exceptions to Bugsnag, you can pass any NSException to the notify method:

[Bugsnag notify:[NSException exceptionWithName:@"ExceptionName" reason:@"Something bad happened" userInfo:nil]];

You can also send additional meta-data with your exception:

[Bugsnag notify:[NSException exceptionWithName:@"ExceptionName" reason:@"Something bad happened" userInfo:nil]
       withData:[NSDictionary dictionaryWithObjectsAndKeys:@"username", @"bob-hoskins", nil]];

Configuration

###context

Bugsnag uses the concept of "contexts" to help display and group your errors. Contexts represent what was happening in your application at the time an error occurs. The iOS Notifier will set this to be the top most UIViewController, but if in a certain case you need to override the context, you can do so using this property:

[Bugsnag instance].context = @"MyUIViewController";

###userId

Bugsnag helps you understand how many of your users are affected by each error. In order to do this, we send along a userId with every exception. By default we will generate a unique ID and send this ID along with every exception from an individual device.

If you would like to override this userId, for example to set it to be a username of your currently logged in user, you can set the userId property:

[Bugsnag instance].setUserId = @"leeroy-jenkins";

###releaseStage

In order to distinguish between errors that occur in different stages of the application release process a release stage is sent to Bugsnag when an error occurs. This is automatically configured by the iOS notifier to be "production", unless DEBUG is defined during compilation. In this case it will be set to "development". If you wish to override this, you can do so by setting the releaseStage property manually:

[Bugsnag instance].releaseStage = @"development";

###notifyReleaseStages

By default, we will only notify Bugsnag of exceptions that happen when your releaseStage is set to be "production". If you would like to change which release stages notify Bugsnag of exceptions you can set the notifyReleaseStages property:

[Bugsnag instance].notifyReleaseStages = [NSArray arrayWithObjects:@"development", @"production", nil];

###autoNotify

By default, we will automatically notify Bugsnag of any fatal exceptions in your application. If you want to stop this from happening, you can set autoNotify to NO:

[Bugsnag instance].autoNotify = NO;

###extraData

It if often very useful to send some extra application or user specific data along with every exception. To do this, you can set the extraData property:

[Bugsnag instance].extraData = [NSDictionary dictionaryWithObjectsAndKeys:@"bob-hoskins", @"username", nil];

###dataFilters

Sets the strings to filter out from the extraData dictionary before sending them to Bugsnag. Use this if you want to ensure you don't send sensitive data such as passwords, and credit card numbers to our servers. Any keys which contain these strings will be filtered.

[Bugsnag instance].dataFilters = [NSArray arrayWithObjects:@"password",@"credit-card-number",nil];

By default, dataFilters is set to [NSArray arrayWithObject:@"password"]

###enableSSL

Enables the use of SSL encryption when sending errors to Bugsnag. Enable this if you require the extra security

[Bugsnag instance].enableSSL = NO;

By default, enableSSL is set to NO.
