I want to save automatically my variables (floats) in a property list that I've already create. I can do that with a button, that work good but I want to do that automatically WITH IOS 7 (some methods are deprecated in IOS 6 or 7).
replyToApplicationShouldTerminate
doesn't work...
I save in the property list with a button like that:
-(IBAction)apply:(id)sender
{
{
[nameC1 resignFirstResponder];
[nameC2 resignFirstResponder];
[nameC3 resignFirstResponder];
[nameC4 resignFirstResponder];
[nameC5 resignFirstResponder];
nom1 = [nameC1 text];
nom2 = [nameC2 text];
nom3 = [nameC3 text];
nom4 = [nameC4 text];
nom5 = [nameC5 text];
v1 = [NSString stringWithFormat:@"%d", compteur1];
v2 = [NSString stringWithFormat:@"%d", compteur2];
v3 = [NSString stringWithFormat:@"%d", compteur3];
v4 = [NSString stringWithFormat:@"%d", compteur4];
v5 = [NSString stringWithFormat:@"%d", compteur5];
//Write in Data.plist
NSString *error;
NSString *rootPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *plistPath = [rootPath stringByAppendingPathComponent:@"Data.plist"];
NSDictionary *plistDict = [NSDictionary dictionaryWithObjects:
[NSArray arrayWithObjects: nom1, nom2, nom3, nom4, nom5, v1, v2, v3, v4, v5, nil] forKeys:[NSArray arrayWithObjects: @"nomCompteur1", @"nomCompteur2", @"nomCompteur3", @"nomCompteur4", @"nomCompteur5", @"valeurCompteur1", @"valeurCompteur2", @"valeurCompteur3", @"valeurCompteur4", @"valeurCompteur5",nil]];
NSData *plistData = [NSPropertyListSerialization dataFromPropertyList:plistDict
format:NSPropertyListXMLFormat_v1_0
errorDescription:&error];
if(plistData) {
[plistData writeToFile:plistPath atomically:YES];
}
else {
NSLog(@"error");
//[error release];
}
}
}
In after the nib is loaded, register a notification for value changes in each of your text fields:
And when the text changes, save the data:
You might want to get a bit more fancy, and use
dispatch_after()
to wait ~0.5 seconds before doing the save. That way the user won't notice if the save is a bit slow. But I suspect the save will be very fast in this case.
