我有这段代码根据收到的本地通知调用不同的 NSLog 语句:
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification{
if (notification == automaticBackupNotification)
{
NSLog(@"Backup notification received.");
}
else
{
NSLog(@"Did receive notification: %@, set for date:%@ .", notification.alertBody, notification.fireDate);
}
}
我使用这种方法在另一个类中安排通知:
- (IBAction)automaticValueChanged {
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
if (automaticSwitch.isOn){
[defaults setValue:@"1" forKey:@"automatic"];
//schedule notification
//Set up the local notification
appDelegate.automaticBackupNotification = [[UILocalNotification alloc] init];
if(appDelegate.automaticBackupNotification){
//Repeat the notification according to frequency
if ([backupFrequencyLabel.text isEqualToString:@"Daily"]) {
appDelegate.automaticBackupNotification.repeatInterval = NSDayCalendarUnit;
}
if ([backupFrequencyLabel.text isEqualToString:@"Weekly"]) {
appDelegate.automaticBackupNotification.repeatInterval = NSWeekCalendarUnit;
}
else {
appDelegate.automaticBackupNotification.repeatInterval = NSMonthCalendarUnit;
}
//Set fire date to alert time
NSCalendar *calendar = appDelegate.automaticBackupNotification.repeatCalendar;
if (!calendar) {
calendar = [NSCalendar currentCalendar];
}
NSDateComponents *components = [[NSDateComponents alloc] init];
components.day = 1;
//NSDate *nextFireDate = [calendar dateByAddingComponents:components toDate:[NSDate date] options:0];
//appDelegate.automaticBackupNotification.fireDate = nextFireDate;
appDelegate.automaticBackupNotification.fireDate = [NSDate dateWithTimeIntervalSinceNow:20.0];
//Set time zone to default
appDelegate.automaticBackupNotification.timeZone = [NSTimeZone defaultTimeZone];
// schedule notification
UIApplication *app = [UIApplication sharedApplication];
[app scheduleLocalNotification:appDelegate.automaticBackupNotification];
NSLog(@"Backup Fire Date: %@", appDelegate.automaticBackupNotification.fireDate);
}
}
else {
[defaults setValue:@"0" forKey:@"automatic"];
if(appDelegate.automaticBackupNotification){
[[UIApplication sharedApplication] cancelLocalNotification:appDelegate.automaticBackupNotification];
}
}
[defaults synchronize];
}
但是,当应用程序委托收到通知时,它会触发条件的“else”部分。有什么办法可以区分不同的通知吗?还是我做错了什么?
干杯,
