Last Crash Notification


Listen to this notification to get crash data from the previous session. The notification userInfo contains some useful information related to the crash.

The following example shows how you can register to receive crash notifications.

NSNotificationCenter *center = [NSNotificationCenter defaultCenter];
NSOperationQueue *mainQueue = [NSOperationQueue mainQueue]; = [center addObserverForName:CrittercismDidCrashOnLastLoadNotification
                                usingBlock:^(NSNotification *notification) {

        NSString *crashName = notification.userInfo[CrittercismCrashName];
        NSString *crashReason = notification.userInfo[CrittercismCrashReason];
        NSDate *crashDate = notification.userInfo[CrittercismCrashDate];
        NSArray *crashViews = notification.userInfo[CrittercismCrashView];
        // ...
// Swift 2.X
let center = NSNotificationCenter.defaultCenter()
let mainQueue = NSOperationQueue.mainQueue()
self.localeChangeObserver = center.addObserverForName(NSCurrentLocaleDidChangeNotification,
                                              object: nil,
                                               queue: mainQueue) { (notification) in

   let crashName = notification.userInfo[CrittercismCrashName];
   let crashReason = notification.userInfo[CrittercismCrashReason];
   let crashDate = notification.userInfo[CrittercismCrashDate];
   let crashViews = notification.userInfo[CrittercismCrashView];
   // ...

// Swift 3.x
let center = NotificationCenter.default
let mainQueue = OperationQueue.main
let localChangeObserver = center.addObserver(forName: NSLocale.currentLocaleDidChangeNotification,
                                            object: nil,
                                            queue: mainQueue) { (notification) in

    let crashName = notification.userInfo?[CrittercismCrashName];
    let crashReason = notification.userInfo?[CrittercismCrashReason];
    let crashDate = notification.userInfo?[CrittercismCrashDate];
    let crashViews = notification.userInfo?[CrittercismCrashView];
    // ...
NSString * const CrittercismDidCrashOnLastLoadNotification
// Swift 2.x and 3.x

let CrittercismDidCrashOnLastLoadNotification: String
Last Crash UserInfo Keys

By default, Workspace ONE Intelligence SDK prints a few messages (via NSLog) to the device log that may be useful to verify that Workspace ONE Intelligence SDK is initialized and properly working. If you don’t want to see Workspace ONE Intelligence log messages, you can tune the amount of logging that is displayed.

See Setting Log Verbosity Of Workspace ONE Intelligence SDK of how to tweak the logging level

typedef enum : NSInteger {
} CRLoggingLevel;
// Swift 2.X and 3.x

enum CRLoggingLevel : Int {
    case Silent
    case Error
    case Warning
    case Info
    case Debug
CRLoggingLevelSilent Turns off all Workspace ONE Intelligence SDK log messages
CRLoggingLevelError Only print errors. An error is an unexpected event that will result not capturing important data
CRLoggingLevelWarning (Default) Only print warnings. Currently warning messages are printed when calling Workspace ONE Intelligence SDK methods before initializing Workspace ONE Intelligence
CRLoggingLevelInfo The most verbose level of logging
CRLoggingLevelDebug Print internal logging in Workspace ONE Intelligence SDK. Please use this logging level and attach your log in your email to our support
