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;
}
}
01. 第一步：创建本地推送
02. // 创建一个本地推送
03. UILocalNotification *notification = [[[UILocalNotification alloc] init] autorelease];
04. //设置10秒之后
05. NSDate *pushDate = [NSDate dateWithTimeIntervalSinceNow:10];
06. if (notification != nil) {
07. // 设置推送时间
08. notification.fireDate = pushDate;
09. // 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];
25.
26. }
27.
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. }
35.
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. }
58.
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. }
64.
65. if (localNotification) {
66. //不推送 取消推送
67. [app cancelLocalNotification:localNotification];
68. [localNotification release];
69. return;
70. }
71. }
