没有机会接触大型项目，跳槽难
第一步：創立本地推送
// 創立一個本地推送
UILocalNotification notification = [[[UILocalNotification alloc] init] autorelease];
//設置10秒之後
NSDate pushDate = [NSDate dateWithTimeIntervalSinceNow:10];
if (notification != nil) {
// 設置推送時間
notification.fireDate = pushDate;
// 設置時區
notification.timeZone = [NSTimeZone defaultTimeZone];
// 設置反復距離
notification.repeatInterval = kCFCalendarUnitDay;
// 推送聲音
notification.soundName = UILocalNotificationDefaultSoundName;
// 推送内容
notification.alertBody = @"推送内容";
//顯現在icon上的红色圈中的數子
notification.applicationIconBadgeNumber = 1;
//設置userinfo 便當在之後需求撤銷的時分運用
NSDictionary info = [NSDictionary dictionaryWithObject:@"name"forKey:@"key"];
notification.userInfo = info;
//添加推送到UIApplication
UIApplication app = [UIApplication sharedApplication];
[app scheduleLocalNotification:notification];
}
第二步：接纳本地推送
(void)application:(UIApplication )application didReceiveLocalNotification:(UILocalNotification)notification{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"iWeibo" message:notification.alertBody delegate:nil cancelButtonTitle:@"肯定" otherButtonTitles:nil];
[alert show];
// 圖標上的數字減1
application.applicationIconBadgeNumber -= 1;
}
第三步：解除本地推送
// 取得 UIApplication
UIApplication app = [UIApplication sharedApplication];
//獲取本地推送數組
NSArray localArray = [app scheduledLocalNotifications];
//聲明本地通知對象
UILocalNotification localNotification;
if (localArray) {
for (UILocalNotification noti in localArray) {
NSDictionary dict = noti.userInfo;
if (dict) {
NSString inKey = [dict objectForKey:@"key"];
if ([inKey isEqualToString:@"對應的key值"]) {
if (localNotification){
[localNotification release];
localNotification = nil;
}
localNotification = [noti retain];
break;
}
}
}
复制
//判別能否找到曾經存在的相同key的推送
if (!localNotification) {
//不存在初始化
localNotification = [[UILocalNotification alloc] init];
}
if (localNotification) {
//不推送 取消推送
[app cancelLocalNotification:localNotification];
[localNotification release];
return;
}
}
