如何在iPhone中设置闹钟并保存在本地通知中? [英] How to set the alarm in iPhone and save in local notification?
问题描述
我正在iPhone中创建一个警报应用程序，该应用程序使用SQLite和本地通知.我有一个带有tableview的类，其中包含4行用于选择时间，重复间隔，声音等.当我选择所有这些因素时，这些都存储在全局变量中.
I am creating an alarm application in iPhone which makes use of SQLite and local notification. I have class with tableview which contains 4 rows for selecting time,repeat interval, sound etc. When I select all these factors these are stored in global variables.
在我选择这些行的表格视图中，我有一个保存按钮.在选择特定的行后单击保存按钮时，通过此全局变量将时间，重复和声音的值保存在SQLite数据库中.现在，我将此变量传递给通知对象，以便在单击保存按钮时设置警报.但是通知没有设置.
In my tableview where I am selecting these rows I have a save button. When I click on the save button after choosing the particular rows the values of time, repeat and sound are saved in SQLite database through this global variables. Now I am passing this variables to my notification objects so that alarm should get set when I click on the save button. But notification is not getting set.
这是我的通知代码:

sqlite3_stmt *compiledStatement;

}
if (sqlite3_step(compiledStatement)!= SQLITE_DONE) {
NSLog(@"Save Error:%s",sqlite3_errmsg(database));
}
else {
sqlite3_reset(compiledStatement);
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"UIAlertView" message:@"Alarm Set" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
[alert show];
[alert release];
alert = nil;
}
sqlite3_finalize(compiledStatement);
}
sqlite3_close(database);
}
-(IBAction)save{
if (lblDate.text == NULL && interval == NULL && newsound == NULL)
{
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"UIAlertView" message:@"Set Date,interval,sound for alarm" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
[alert show];
[alert release];
alert = nil;
}
else {
[self saveInDatabase];
[self schedulealarm];
}
//[self.navigationController popViewControllerAnimated:YES];
}
@end
然后在appDelegate中，我为didReceiveNotification创建了一个方法.但是通知不起作用.我的开火日期显示为空值.
And in the appDelegate I have created a method for didReceiveNotification. But notification does not work. My fire date shows null value.
可能是什么问题?我想将值传递给存储在变量中的日期.
What might be the problem? I want to pass values to firedate that I stored in my variable.
推荐答案
我认为在设置fireDate时发生问题，您可以尝试以下方法:
I think problem happen when you set fireDate, you can try this:
NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
NSDateComponents *components = [[NSDateComponents alloc] init];
[components setDay:day];
[components setMonth:month];
[components setYear:year];
[components setMinute:minutes];
[components setHour:hour];
NSDate *date = [calendar dateFromComponents:components];
localNotif.fireDate = date;
