設定バンドルを使用して UILocalNotification をスケジュールしようとしています。設定では、通知を毎日 (1 日 1 回)、2 日に 1 回、日曜日のみ、またはまったく通知しないようにするかを選択できます。
これが私が使用したコードです（これはすべてAppDelegate.mにあります）：
-(void)defaultsChanged:(NSNotification *)notification {
[[UIApplication sharedApplication] cancelAllLocalNotifications];
[[NSUserDefaults standardUserDefaults]synchronize];
NSString *testValue = [[NSUserDefaults standardUserDefaults] stringForKey:@"multi_preference"];
NSLog(@"%@", testValue);
NSDate *today = [NSDate date];
NSCalendar* calendar = [NSCalendar currentCalendar];
NSDateComponents* compoNents = [calendar components:NSYearCalendarUnit|NSMonthCalendarUnit|NSDayCalendarUnit fromDate:today]; // Get necessary date components
[compoNents month];[compoNents day];
NSDictionary *dictToday= [self getDataFromdate : [compoNents day] month:[compoNents month]];
if ([testValue isEqualToString:@"one"]){
UILocalNotification* localNotification = [[UILocalNotification alloc] init];
localNotification.fireDate = [[NSDate date]dateByAddingTimeInterval:20];
localNotification.alertAction = @"View";
localNotification.alertBody = [dictToday objectForKey:@"saint_description"];
localNotification.repeatInterval = NSDayCalendarUnit;
localNotification.timeZone = [NSTimeZone defaultTimeZone];
localNotification.applicationIconBadgeNumber = [[UIApplication sharedApplication] applicationIconBadgeNumber] + 1;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
[[NSNotificationCenter defaultCenter] postNotificationName:@"reloadData" object:self];
}
if (testValue==Nil){
UILocalNotification* localNotification = [[UILocalNotification alloc] init];
localNotification.fireDate = [[NSDate date]dateByAddingTimeInterval:20];
localNotification.alertAction = @"View";
localNotification.alertBody = [dictToday objectForKey:@"saint_description"];
localNotification.repeatInterval = NSDayCalendarUnit;
localNotification.timeZone = [NSTimeZone defaultTimeZone];
localNotification.applicationIconBadgeNumber = [[UIApplication sharedApplication] applicationIconBadgeNumber] + 1;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
[[NSNotificationCenter defaultCenter] postNotificationName:@"reloadData" object:self];
}
if ([testValue isEqualToString:@"two"]){
UILocalNotification* localNotification = [[UILocalNotification alloc] init];
localNotification.fireDate = [[NSDate date]dateByAddingTimeInterval:86401];
localNotification.alertAction = @"View";
localNotification.alertBody = [dictToday objectForKey:@"saint_description"];
localNotification.repeatInterval = NSDayCalendarUnit;
localNotification.timeZone = [NSTimeZone defaultTimeZone];
localNotification.applicationIconBadgeNumber = [[UIApplication sharedApplication] applicationIconBadgeNumber] + 1;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
[[NSNotificationCenter defaultCenter] postNotificationName:@"reloadData" object:self];
}
if ([testValue isEqualToString:@"three"]){
NSDate *today2 = [[NSDate alloc] init];
NSCalendar *gregorian = [[NSCalendar alloc]
initWithCalendarIdentifier:NSGregorianCalendar];
// Get the weekday component of the current date
NSDateComponents *weekdayComponents = [gregorian components:NSWeekdayCalendarUnit
fromDate:today2];
/*
Create a date components to represent the number of days to subtract from the current date.
The weekday value for Sunday in the Gregorian calendar is 1, so subtract 1 from the number of days to subtract from the date in question. (If today is Sunday, subtract 0 days.)
*/
NSDateComponents *componentsToSubtract = [[NSDateComponents alloc] init];
[componentsToSubtract setDay: 0 - ([weekdayComponents weekday] - 1)];
NSDate *beginningOfWeek = [gregorian dateByAddingComponents:componentsToSubtract
toDate:today2 options:0];
/*
Optional step:
beginningOfWeek now has the same hour, minute, and second as the original date (today).
To normalize to midnight, extract the year, month, and day components and create a new date from those components.
*/
NSDateComponents *components =
[gregorian components:(NSYearCalendarUnit | NSMonthCalendarUnit |
NSDayCalendarUnit) fromDate: beginningOfWeek];
beginningOfWeek = [gregorian dateFromComponents:components];
UILocalNotification* localNotification = [[UILocalNotification alloc] init];
localNotification.fireDate = beginningOfWeek;
localNotification.alertAction = @"View";
localNotification.alertBody = [dictToday objectForKey:@"saint_description"];
localNotification.repeatInterval = NSWeekdayCalendarUnit;
localNotification.timeZone = [NSTimeZone defaultTimeZone];
localNotification.applicationIconBadgeNumber = [[UIApplication sharedApplication] applicationIconBadgeNumber] + 1;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
[[NSNotificationCenter defaultCenter] postNotificationName:@"reloadData" object:self];
}
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(defaultsChanged:)
name:NSUserDefaultsDidChangeNotification
object:nil];
UILocalNotification *locationNotification = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
if (locationNotification) {
// Set icon badge number to zero
application.applicationIconBadgeNumber = 0;
}
return yes;
}
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Today's Saint"
message:notification.alertBody
delegate:self cancelButtonTitle:@"OK"
otherButtonTitles:nil];
if (notification.alertBody!=Nil)
[alert show];
[[NSNotificationCenter defaultCenter] postNotificationName:@"reloadData" object:self];
// Set icon badge number to zero
application.applicationIconBadgeNumber = 0;
}
私が述べたように、通知を起動するためのコードは正しいですか? そうでない場合、何が問題なのですか？ありがとう！
