- 引入头文件
#import <UserNotifications/UserNotifications.h>
- 注册通知
/*
注册通知(推送)
申请App需要接受来自服务商提供推送消息
*/
if (@available(iOS 10.0, *)) {
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
center.delegate = self;
[center requestAuthorizationWithOptions:UNAuthorizationOptionAlert | UNAuthorizationOptionSound | UNAuthorizationOptionBadge completionHandler:^(BOOL granted, NSError * _Nullable error) {
if (!granted) {
[self showNoticeAlert];
}
}];
// 注册远程通知
[[UIApplication sharedApplication] registerForRemoteNotifications];
}
- 检查通知权限
- (void)checkNotificationAuth:(void(^)(BOOL granted))block
{
if (@available(iOS 10.0, *)) {
[[UNUserNotificationCenter currentNotificationCenter] getNotificationSettingsWithCompletionHandler:^(UNNotificationSettings * _Nonnull settings) {
if (settings.authorizationStatus == UNAuthorizationStatusAuthorized) {
block(YES);
}else {
block(NO);
}
}];
}else {
if ([[UIApplication sharedApplication] currentUserNotificationSettings].types == UIUserNotificationTypeNone) {
block(NO);
}else {
block(YES);
}
}
}
- 发送本地通知
if (@available(iOS 10.0, *)) {
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
UNMutableNotificationContent *content = [[UNMutableNotificationContent alloc] init];
content.title = @"title";
content.body = @"body";
content.badge = 0;
content.userInfo = @{};
NSTimeInterval timeInterval = [[NSDate dateWithTimeIntervalSinceNow:1] timeIntervalSinceNow];
// repeats，是否重复，如果重复的话时间必须大于60s，要不会报错
UNTimeIntervalNotificationTrigger *trigger = [UNTimeIntervalNotificationTrigger triggerWithTimeInterval:timeInterval repeats:NO];
UNNotificationRequest *reqeust = [UNNotificationRequest requestWithIdentifier:@"noticeIdentifier" content:content trigger:trigger];
[center addNotificationRequest:reqeust withCompletionHandler:^(NSError * _Nullable error) {
if (error) {
DLog(@"error");
}
}];
}
5.发送本地通知一定要实现以下代理方法
//App在前台时候回调：用户正在使用状态
- (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler
{
completionHandler(UNNotificationPresentationOptionSound | UNNotificationPresentationOptionBadge | UNNotificationPresentationOptionAlert);
}
- 通知代理方法
// 推送消息回调
- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)(void))completionHandler
{
if ([response.notification.request.trigger isKindOfClass:[UNPushNotificationTrigger class]]) {
// 远程推送消息处理
} else {
// 本地消息处理
}
completionHandler();
}
