iOS 本地通知
//联系人:石虎 QQ: 1224614774 昵称:嗡嘛呢叭咪哄
/**
注意:本地通知 直接拷贝到AppDelegate.h文件中,和主控制器中即可完成
*/
效果:
=======================================================
#import "AppDelegate.h"
@implementation AppDelegate
// 只有当应用在前台时，该方法才会被调用
- (void)application:(UIApplication *)application
didReceiveLocalNotification:(UILocalNotification*)notification{
// 如果应用程序在前台，将应用程序图标上红色徽标中数字设为0
application.applicationIconBadgeNumber = 0;
// 使用UIAlertView显示本地通知的信息
[[[UIAlertView alloc] initWithTitle:@"收到通知"
message:notification.alertBody
delegate:nil cancelButtonTitle:@"确定" otherButtonTitles:nil] show];
}
=========================主控制器==============================
XIB 连线图:
#import "ViewController.h"
@interface ViewController ()
{
UIApplication *app;
}
@end
@implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
app = [UIApplication sharedApplication];
}
- (IBAction)changed:(id)sender
{
UISwitch* sw = (UISwitch*) sender;
if (sw.on)
{
if([UIApplication instancesRespondToSelector:@selector(registerUserNotificationSettings:)])
{
[[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert|UIUserNotificationTypeBadge|UIUserNotificationTypeSound categories:nil]];
}
// 创建一个本地通知
UILocalNotification *notification = [[UILocalNotification alloc]init];
// 设置通知的触发时间
notification.fireDate = [NSDate dateWithTimeIntervalSinceNow:10];
// 设置通知的时区
notification.timeZone = [NSTimeZone defaultTimeZone];
// 设置通知的重复发送的事件间隔
notification.repeatInterval = kCFCalendarUnitHour;
// 设置通知的声音
notification.soundName = @"gu.mp3";
//通知标题
notification.alertTitle=@"我是标题";
// 设置当设备处于锁屏状态时，显示通知的警告框下方的title
notification.alertAction = @"打开";
// 设置通知是否可显示Action
notification.hasAction = YES;
// 设置通过通知加载应用时显示的图片
notification.alertLaunchImage = @"logo.png";
// 设置通知内容
notification.alertBody = @"亲,好几天????,想念你了!";
// 设置显示在应用程序上红色徽标中的数字
notification.applicationIconBadgeNumber = 10;
// 设置userinfo，用于携带额外的附加信息。
NSDictionary *info = @{@"bys": @"key"};
notification.userInfo = info;
// 调度通知
[app scheduleLocalNotification:notification]; // ①
}
else
{
// 获取所有处于调度中本地通知数组
NSArray *localArray = [app scheduledLocalNotifications];
if (localArray)
{
for (UILocalNotification *noti in localArray)
{
NSDictionary *dict = noti.userInfo;
if (dict)
{
// 如果找到要取消的通知
NSString *inKey = [dict objectForKey:@"key"];
if ([inKey isEqualToString:@"bys"])
{
// 取消调度该通知
[app cancelLocalNotification:noti]; //
}
}
}
}
