關於推送的機制和推送用到的證書問題在這裡不多說。
關於推送的代碼部分：
客戶端：
1、告訴應用程序，接收push來的消息（當然是放在 didFinishLaunchingWithOptions 方法裡面了）
[cpp]
[application registerForRemoteNotificationTypes:UIRemoteNotificationTypeAlert|UIRemoteNotificationTypeBadge|UIRemoteNotificationTypeSound];
[application registerForRemoteNotificationTypes:UIRemoteNotificationTypeAlert|UIRemoteNotificationTypeBadge|UIRemoteNotificationTypeSound];
2、完成推送比不可缺的東西：deviceToken ，蘋果推送會根據 deviceToken的值進行推送的操作。deviceToken和全球之內的蘋果設備一一對應的，也就是說它是唯一的。
[cpp]
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
NSLog(@"獲取設備的deviceToken: %@", deviceToken);
}
- (void)application:(UIApplication*)application didFailToRegisterForRemoteNotificationsWithError:(NSError*)error{
NSLog(@"Failed to get token, error: %@", error);
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
NSLog(@"獲取設備的deviceToken: %@", deviceToken);
}
- (void)application:(UIApplication*)application didFailToRegisterForRemoteNotificationsWithError:(NSError*)error{
NSLog(@"Failed to get token, error: %@", error);
3、對推送過來的消息進行處理的方法：
[cpp]
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
//以警告框的方式來顯示推送消息
if ([[userInfo objectForKey:@"aps"] objectForKey:@"alert"]!=NULL) {
UIAlertView* alert = [[UIAlertView alloc] initWithTitle:@"經過推送發送過來的消息"
message:[[userInfo objectForKey:@"aps"] objectForKey:@"alert"]
delegate:self
cancelButtonTitle:@"關閉"
otherButtonTitles:@"處理",nil];
[alert show];
[alert release];
}
}
