iOS 4.0之后捻浦，我們就多了一種推送選擇粗卜，即本地推送屋确，可以減輕一些服務(wù)器的壓力。今天和大家簡(jiǎn)單分享下iOS4里的本地推送。
1攻臀、增加一個(gè)本地推送
//設(shè)置20秒之后
NSDate *date = [NSDate dateWithTimeIntervalSinceNow:20];
//chuagjian一個(gè)本地推送
UILocalNotification *noti = [[[UILocalNotification alloc] init] autorelease];
if (noti) {
//設(shè)置推送時(shí)間
noti.fireDate = date;
//設(shè)置時(shí)區(qū)
noti.timeZone = [NSTimeZone defaultTimeZone];
//設(shè)置重復(fù)間隔
noti.repeatInterval = NSWeekCalendarUnit;
//推送聲音
noti.soundName = UILocalNotificationDefaultSoundName;
//內(nèi)容
noti.alertBody = @"推送內(nèi)容";
//顯示在icon上的紅色圈中的數(shù)子
noti.applicationIconBadgeNumber = 1;
//設(shè)置userinfo 方便在之后需要撤銷的時(shí)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焕数、程序運(yùn)行時(shí)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:@"確定"
otherButtonTitles:nil];
[alert show];
//這里，你就可以通過notification的useinfo茵烈，干一些你想做的事情了
application.applicationIconBadgeNumber -= 1;
}
3百匆、取消一個(gè)本地推送
UIApplication *app = [UIApplication sharedApplication];
//獲取本地推送數(shù)組
NSArray *localArr = [app scheduledLocalNotifications];
//聲明本地通知對(duì)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;
}
}
}
//判斷是否找到已經(jīng)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：創(chuàng)建本地推送
02. // 創(chuàng)建一個(gè)本地推送
03. UILocalNotification *notification = [[[UILocalNotification alloc] init] autorelease];
04. //設(shè)置10秒之后
05. NSDate *pushDate = [NSDate dateWithTimeIntervalSinceNow:10];
06. if (notification != nil) {
07. ? ? // 設(shè)置推送時(shí)間
08. ? ? notification.fireDate = pushDate;
09. ? ? // 設(shè)置時(shí)區(qū)
10. ? ? notification.timeZone = [NSTimeZone defaultTimeZone];
11. ? ? // 設(shè)置重復(fù)間隔
12. ? ? notification.repeatInterval = kCFCalendarUnitDay;
13. ? ? // 推送聲音
14. ? ? notification.soundName = UILocalNotificationDefaultSoundName;
15. ? ? // 推送內(nèi)容
16. ? ? notification.alertBody = @"推送內(nèi)容";
17. ? ? //顯示在icon上的紅色圈中的數(shù)子
18. ? ? notification.applicationIconBadgeNumber = 1;
19. ? ? //設(shè)置userinfo 方便在之后需要撤銷的時(shí)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:@"確定" otherButtonTitles:nil];
31. ? ? [alert show];
32. ? ? // 圖標(biāo)上的數(shù)字減1
33. ? ? application.applicationIconBadgeNumber -= 1;
34. }
35.
36. 第三步：解除本地推送
37. // 獲得 UIApplication
38. UIApplication *app = [UIApplication sharedApplication];
39. //獲取本地推送數(shù)組
40. NSArray *localArray = [app scheduledLocalNotifications];
41. //聲明本地通知對(duì)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:@"對(duì)應(yīng)的key值"]) {
49. ? ? ? ? ? ? ? ? if (localNotification){
50. ? ? ? ? ? ? ? ? ? ? [localNotification release];
51. ? ? ? ? ? ? ? ? ? ? localNotification = nil;
52. ? ? ? ? ? ? ? ? }
53. ? ? ? ? ? ? ? ? localNotification = [noti retain];
54. ? ? ? ? ? ? ? ? break;
55. ? ? ? ? ? ? }
56. ? ? ? ? }
57. ? ? }
58.
59. ? ? //判斷是否找到已經(jīng)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. }
