I guess having multiple timers when you cook is very useful, for example. A more descriptive name comes in handy when you have multiple timers active at the same time. Each times is called a "Howler", but you can change the names to whatever you want. It allows you to set any number of timers that can run concurrently. Now your alarm should play whether your app is in foreground, background or not even open.Howler is a very original timer and alarm clock for the Mac. Note that the time you call this method does not need to be, and usually is not, the time when the notification will fire.And you only need to call this once even if you set a recurring notification.You cancel it by calling cancelLocalNotification. You present your notification instance by calling scheduleLocalNotification:, a UIApplication method. The file name of the custom sound goes into the soundName property. Then you set the alert message through alertBody (like "wake up") and the string on the alert button through alertAction. The custom sound can only be 30 seconds or less.Īfter initializing your UILocalNotification object you need to set its firedate property, which is date and time (also recurring) for firing the notification. Now from what I gathered around the internet you should not be looping the sound yourself but instead provide the custom music file in one of these formats in your main app bundle: So all it working well now :)Įven if your app is in the foreground when the device is on, after it's locked it will go to background (willresignactive is called). It turns out it was my app was sucking the cpu. I ran it in it's own separate xCode project and it only uses 0.5% of the cpu when the app is in the background. I am very certain that I need to optimize my app and the battery drain problems will disappear and my problems will be solved! I downloaded some of his apps and ran some instruments tests and saw his app was not draining battery as much as my app is (roughly 2.5% per hour as claimed somewhere on his blog). He is the creator of the Deep Sleep Preventer. I downloaded some of apps from the app store. I need to find a more efficient solution. However, this eats up battery like crazy. I ended up using which let me play a sound after 10 minutes. Summary: While the screen is locked and in the app is in the foreground, I am unable to prevent the process from being killed off after the 10 minute mark.

The system would eventually force close the app When it's time to play an alarm, switch the silent sound to the alarm sound. When the screen is locked fire a timer to check if its time to play an alarm. When the app opens play a silent sound on infinite repeat. That method will display Wake in the music controls and will stop any currently playing music which we want to avoid. In order to continue updating the song while it's in the background. If it is in the locked screen state and it's time to play an alarm, play it. When the sound ends, replay the sound and check if the app is in the Inactive (locked screen) state. Play a 1 second silent sound using AVAudioPlayer. I managed to keep the app open past the 10 minute maximum but I was unable to play a sound. Run an NSTimer every second with a background task when the screen is locked. I've have some limited success while the screen is locked (the and the app is in the Inactive state) To play alarms while the app is in the foreground we fire Local notifications which works great.
I am having some trouble reproducing that functionality. They also do not take control of the music controls (if you open up the multitasking screen and scroll to playing audio, you will not see their icon) Their alarms can play for an unlimited amount of time and can progressively increase in volume using the system volume.

Many other alarm apps such as Alarm Clock Pro are able to play an alarm while the screen is locked and the app is in the foreground. Preface: I'm building an alarm clock app.
