I want to perform particular task in background continuously even my application goes in background.
Here is the code which i tried. Timer is firing only once when it enters in background.
- (void)applicationDidEnterBackground:(UIApplication *)application
{
NSTimer * timer = [NSTimer timerWithTimeInterval:2.0
target:self
selector:@selector(timerTicked)
userInfo:nil
repeats:YES];
[[NSRunLoop mainRunLoop] addTimer:timer
forMode:NSDefaultRunLoopMode];
}
- (void) timerTicked
{
NSLog(@"Timer method");
}
You can't have a timer in background. It may work for a short time but your app will quickly goes into sleep mode if you don't have a registered background mode.
Available modes may be :
Take a look at Background execution documentation for more info
- (void)applicationDidEnterBackground:(UIApplication *)application {
UIBackgroundTaskIdentifier bgTask = UIBackgroundTaskInvalid;
bgTask = [[UIApplication sharedApplication]
beginBackgroundTaskWithExpirationHandler:^{
[[UIApplication sharedApplication] endBackgroundTask:bgTask];
}];
// NotificationTimer its timer
// myMethod1 call ur method
NotificationTimer = [NSTimer scheduledTimerWithTimeInterval: Interval
target: self
selector:@selector(myMethod1)
userInfo: nil repeats:YES];
}
I think its help to u
