有人能帮我实现 iOS 10 的推送通知吗?我已经按照下面的代码实现了,但仍然遇到问题:
#define SYSTEM_VERSION_GRATERTHAN_OR_EQUALTO(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending)
if(SYSTEM_VERSION_GRATERTHAN_OR_EQUALTO(@"10.0"))
{
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
center.delegate = self;
[center requestAuthorizationWithOptions:(UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionBadge) completionHandler:^(BOOL granted, NSError * _Nullable error){
if(!error){
[[UIApplication sharedApplication] registerForRemoteNotifications];
}
}];
}
else {
// Code for old versions
}
我遇到了错误,提示如下:
未知接收器 UIUserNotificationCenter
提前谢谢!
