[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(objChange:) name:NSUbiquitousKeyValueStoreDidChangeExternallyNotification object:nil];
NSConcreteNotification 0x1c024ab60
{
name = NSUbiquitousKeyValueStoreDidChangeExternallyNotification;
object = <NSUbiquitousKeyValueStore: 0x1c4281cc0>;
userInfo = {
NSUbiquitousKeyValueStoreChangeReasonKey = 0;
NSUbiquitousKeyValueStoreChangedKeysKey = (
store
);
}}
其中object就是NSUbiquitousKeyValueStore,可以从这里取值;
- (void)objChange:(NSNotification *)note
{
NSString *store = [note.object objectForKey:@"store"];
NSLog(@"store == %@",store);
self.lb.text = store;
}
