ios推送：本地通知UILocalNotification

//发送通知

UILocalNotification *notification=[[UILocalNotification alloc] init];
if (notification!=nil) {
NSDate *now=[NSDate new];
notification.fireDate=[now dateByAddingTimeInterval:10];//10秒后通知
notification.repeatInterval=0;//循环次数，kCFCalendarUnitWeekday一周一次
notification.timeZone=[NSTimeZone defaultTimeZone];
notification.applicationIconBadgeNumber=1; //应用的红色数字
notification.soundName= UILocalNotificationDefaultSoundName;//声音，可以换成alarm.soundName = @"myMusic.caf"
//去掉下面2行就不会弹出提示框
notification.alertBody=@"通知内容";//提示信息 弹出提示框
notification.alertAction = @"打开"; //提示框按钮
//notification.hasAction = NO; //是否显示额外的按钮，为no时alertAction消失

// NSDictionary *infoDict = [NSDictionary dictionaryWithObject:@"someValue" forKey:@"someKey"];
//notification.userInfo = infoDict; //添加额外的信息

[[UIApplication sharedApplication] scheduleLocalNotification:notification];
}
[notification release];

取消通知

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

// Override point for customization after application launch.
application.applicationIconBadgeNumber = 0;
// Add the view controller's view to the window and display.
[window addSubview:viewController.view];
[window makeKeyAndVisible];

return YES;
}
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification {
//点击提示框的打开
application.applicationIconBadgeNumber = 0;
}
- (void)applicationDidBecomeActive:(UIApplication *)application {
//当程序还在后天运行
application.applicationIconBadgeNumber = 0;
}


///////////////////////////////////////iOS 4.0之后，我们就多了一种推送选择，即本地推送，可以减轻一些服务器的压力。今天和大家简单分享下iOS4里的本地推送。
1、增加一个本地推送//设置20秒之后

NSDate *date = [NSDate dateWithTimeIntervalSinceNow:20];

//chuagjian一个本地推送

UILocalNotification *noti = [[[UILocalNotification alloc] init] autorelease];

if (noti) {

//设置推送时间

noti.fireDate = date;

//设置时区

noti.timeZone = [NSTimeZone defaultTimeZone];

//设置重复间隔

noti.repeatInterval = NSWeekCalendarUnit;

//推送声音

noti.soundName = UILocalNotificationDefaultSoundName;

//内容

noti.alertBody = @"推送内容";

//显示在icon上的红色圈中的数子

noti.applicationIconBadgeNumber = 1;

//设置userinfo 方便在之后需要撤销的时候使用

NSDictionary *infoDic = [NSDictionary dictionaryWithObject:@"name" forKey:@"key"];

noti.userInfo = infoDic;

//添加推送到uiapplication

UIApplication *app = [UIApplication sharedApplication];

[app scheduleLocalNotification:noti];

}

2、程序运行时接收到本地推送消息

- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification*)notification

{

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"接收到本地提醒 in app"

message:notification.alertBody

delegate:nil

cancelButtonTitle:@"确定"

otherButtonTitles:nil];

[alert show];

//这里，你就可以通过notification的useinfo，干一些你想做的事情了

application.applicationIconBadgeNumber -= 1;

}

3、取消一个本地推送

UIApplication *app = [UIApplication sharedApplication];

//获取本地推送数组

NSArray *localArr = [app scheduledLocalNotifications];

//声明本地通知对象

UILocalNotification *localNoti;

if (localArr) {

for (UILocalNotification *noti in localArr) {

NSDictionary *dict = noti.userInfo;

if (dict) {

NSString *inKey = [dict objectForKey:@"key"];

if ([inKey isEqualToString:key]) {

if (localNoti){

[localNoti release];

localNoti = nil;

}

localNoti = [noti retain];

break;

}

}

}

//判断是否找到已经存在的相同key的推送

if (!localNoti) {

//不存在 初始化

localNoti = [[UILocalNotification alloc] init];

}

if (localNoti && !state) {

//不推送 取消推送

[app cancelLocalNotification:localNoti];

[localNoti release];

return;

}

}

1. 第一步：创建本地推送
2. // 创建一个本地推送
3. UILocalNotification *notification = [[[UILocalNotification alloc] init] autorelease];
4. //设置10秒之后
5. NSDate *pushDate = [NSDate dateWithTimeIntervalSinceNow:10];
6. if (notification != nil) {
7. // 设置推送时间
8. notification.fireDate = pushDate;
9. // 设置时区
10. notification.timeZone = [NSTimeZone defaultTimeZone];
11. // 设置重复间隔
12. notification.repeatInterval = kCFCalendarUnitDay;
13. // 推送声音
14. notification.soundName = UILocalNotificationDefaultSoundName;
15. // 推送内容
16. notification.alertBody = @"推送内容";
17. //显示在icon上的红色圈中的数子
18. notification.applicationIconBadgeNumber = 1;
19. //设置userinfo 方便在之后需要撤销的时候使用
20. NSDictionary *info = [NSDictionary dictionaryWithObject:@"name"forKey:@"key"];
21. notification.userInfo = info;
22. //添加推送到UIApplication
23. UIApplication *app = [UIApplication sharedApplication];
24. [app scheduleLocalNotification:notification];
26. }
28. 第二步：接收本地推送
29. - (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification*)notification{
30. UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"iWeibo" message:notification.alertBody delegate:nil cancelButtonTitle:@"确定" otherButtonTitles:nil];
31. [alert show];
32. // 图标上的数字减1
33. application.applicationIconBadgeNumber -= 1;
34. }
36. 第三步：解除本地推送
37. // 获得 UIApplication
38. UIApplication *app = [UIApplication sharedApplication];
39. //获取本地推送数组
40. NSArray *localArray = [app scheduledLocalNotifications];
41. //声明本地通知对象
42. UILocalNotification *localNotification;
43. if (localArray) {
44. for (UILocalNotification *noti in localArray) {
45. NSDictionary *dict = noti.userInfo;
46. if (dict) {
47. NSString *inKey = [dict objectForKey:@"key"];
48. if ([inKey isEqualToString:@"对应的key值"]) {
49. if (localNotification){
50. [localNotification release];
51. localNotification = nil;
52. }
53. localNotification = [noti retain];
54. break;
55. }
56. }
57. }
59. //判断是否找到已经存在的相同key的推送
60. if (!localNotification) {
61. //不存在初始化
62. localNotification = [[UILocalNotification alloc] init];
63. }
65. if (localNotification) {
66. //不推送 取消推送
67. [app cancelLocalNotification:localNotification];
68. [localNotification release];
69. return;
70. }
71. }
