问题描述
我需要为项目提供向后兼容性(iOS 9).我想到了这个:
I need to give backward compatibility (iOS 9) to a project. I came up with this:
if #available(iOS 10.0, *) {
let content = UNMutableNotificationContent()
} else {
// Fallback on earlier versions
}
我应该在Fallback中写些什么?我需要创建本地通知实例吗?
What should I write in Fallback? Do I need to create a local notification instance?
推荐答案
以下是支持两个版本的一个小示例:
Here is a small example on supporting both version:
Objective-c版本:
Objective-c version:
if #available(iOS 10.0, *) {
UNMutableNotificationContent *objNotificationContent = [[UNMutableNotificationContent alloc] init];
objNotificationContent.body = @"Notifications";
objNotificationContent.badge = @([[UIApplication sharedApplication] applicationIconBadgeNumber] + 1);
UNTimeIntervalNotificationTrigger *trigger = [UNTimeIntervalNotificationTrigger triggerWithTimeInterval:60 repeats:NO];
UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:@"identifier" content:objNotificationContent trigger:trigger];
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
[center addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) {
if (!error) {
}
else {
}
}];
}
else
{
UILocalNotification *localNotif = [[UILocalNotification alloc] init];
localNotif.fireDate = [[NSDate date] dateByAddingTimeIntervalInterval:60];
localNotif.alertBody = @"Notifications";
localNotif.repeatInterval = NSCalendarUnitMinute;
localNotif.applicationIconBadgeNumber = 0;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotif];
}
快速版本:
if #available(iOS 10.0, *) {
let content = UNMutableNotificationContent()
content.categoryIdentifier = "awesomeNotification"
content.title = "Notification"
content.body = "Body"
let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 60, repeats: false)
let request = UNNotificationRequest(identifier: "FiveSecond", content: content, trigger: trigger)
let center = UNUserNotificationCenter.current()
center.add(request) { (error) in
}
}
else
{
let notification = UILocalNotification()
notification.alertBody = "Notification"
notification.fireDate = NSDate(timeIntervalSinceNow:60)
notification.repeatInterval = NSCalendarUnit.Minute
UIApplication.sharedApplication().cancelAllLocalNotifications()
UIApplication.sharedApplication().scheduledLocalNotifications = [notification]
}
