I am already aware of the fact that there is an option for us to send sms programmatically i.e. using MFMessageComposeViewController, but is it possible to schedule the message to the specified recipient. I am currently using the following code to send sms:
Class smsClass = (NSClassFromString(kMessageComposer));
if(smsClass != nil && [MFMessageComposeViewController canSendText])
{
MFMessageComposeViewController *smsSendController = [[[MFMessageComposeViewController alloc] init] autorelease];
smsSendController.messageComposeDelegate = self;
smsSendController.body = messageBodyView.text;
smsSendController.recipients = [[[NSArray alloc]initWithObjects:numberField.text,nil]autorelease];
if ([[[UIDevice currentDevice]systemVersion]floatValue] >= 6.0)
{
[self presentViewController:smsSendController animated:YES completion:nil];
}
else
{
[self presentModalViewController:smsSendController animated:YES];
}
}
- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result
{
switch (result)
{
case MessageComposeResultCancelled:
{
UIAlertView *smsCancelledAlert = [[UIAlertView alloc] initWithTitle:kApp message:kCancel
delegate:self cancelButtonTitle:kOk otherButtonTitles: nil];
[smsCancelledAlert show];
[smsCancelledAlert release];
}
break;
case MessageComposeResultFailed:
{
UIAlertView *smsFailedAlert = [[UIAlertView alloc] initWithTitle:kApp message:kError
delegate:self cancelButtonTitle:kOk otherButtonTitles: nil];
[smsFailedAlert show];
[smsFailedAlert release];
}
break;
case MessageComposeResultSent:
{
UIAlertView *smsSentAlert = [[UIAlertView alloc]initWithTitle:kApp message:kSent delegate:self cancelButtonTitle:kOk otherButtonTitles:nil, nil];
[smsSentAlert show];
[smsSentAlert release];
}
break;
default:
break;
}
if ([[[UIDevice currentDevice]systemVersion]floatValue] >= 6.0)
{
[self dismissViewControllerAnimated:YES completion:nil];
}
else
{
[self dismissModalViewControllerAnimated:YES];
}
}
I also would like to know whether this code works perfect in all versions above 4.3 till date 6.0. As of now I don't have the device available to test this. So would need some answers from some one who experienced this code as working/failed.
In addition to this, I would want to schedule the message i.e. user specified date&time and the process should be running in background without any user interaction.
How to achieve this?
With MFMessageComposerViewController it is not possible to send without user interaction.
you may consider creating a custom webservice to sms gateway to do achieve this

I'm currently working in Xcode on an iOS app...
I've set up a UIAlertView (with a question as the message ) to pop up with a text field to retrieve a response.
The desired functionality is that upon entering an incorrect value into the text field, the UIAlert would loop... Until the correct response is entered. At this point, the UIAlert would be dismissed.
Heres what I have so far...
- (void)application:(UIApplication *)application
didReceiveLocalNotification:(UILocalNotification *)notification {
NSString* correctAnswer = #"2";
UIAlertView *alert = [[UIAlertView alloc]
initWithTitle:#"Alarm"
message:#"1 + 1 ="
delegate:self
cancelButtonTitle: nil
otherButtonTitles:#"Continue", nil ];
alert.alertViewStyle = UIAlertViewStylePlainTextInput;
UITextField* answerField = [alert textFieldAtIndex:0];
answerField.keyboardType = UIKeyboardTypeNumberPad;
answerField.placeholder = #"answer";
[alert show];
// I feel like this would work, but I know it doesn't...
NSString *answerFieldString = answerField.text;
if ([answerFieldString isEqualToString: correctAnswer ])
{
[alert dismissWithClickedButtonIndex:-1 animated:YES];
}
}
I've done extensive google searching and can't come up with a solution... Any responses would be much appreciated!
try this...
- (BOOL)alertViewShouldEnableFirstOtherButton:(UIAlertView *)alertView
{
NSString *answerFieldString = answerField.text;
if ([answerFieldString isEqualToString: correctAnswer ])
{
[alertView dismissWithClickedButtonIndex:-1 animated:YES];
}
}
Is there a way to discover whether the current connection is 3G, Edge or WiFi, and receive a notification of this? Or just a way do discover whether the connection is WiFi?
You should use Apple's Reachability class
http://developer.apple.com/library/ios/#samplecode/Reachability/Listings/Classes_Reachability_h.html
after implementation you can use this in the delegate:
- (void) configureTextField: (Reachability*) curReach
{
NetworkStatus netStatus = [curReach currentReachabilityStatus];
BOOL connectionRequired= [curReach connectionRequired];
NSString* statusString= #"non";
switch (netStatus)
{
case NotReachable:
{
statusString = #"Access Not Available";
//Minor interface detail- connectionRequired may return yes, even when the host is unreachable. We cover that up here...
connectionRequired= NO;
break;
}
case ReachableViaWWAN:
{
statusString = #"Reachable WWAN";
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Cellular Data Detected" message:#"You are using Cellular data such as 3G or Edge. Downloading large amount of data may effect your cellular internet package costs. To avoid such extra cost kindly use Wifi."
delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alert show];
[alert release];
break;
}
case ReachableViaWiFi:
{
statusString= #"Reachable WiFi";
break;
}
}
if(connectionRequired)
{
statusString= [NSString stringWithFormat: #"%#, Connection Required", statusString];
}
NSLog(#"Network= %#",statusString);
if ([statusString isEqualToString:#"Access Not Available"]){
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"No Internet Connection" message:#"It seems you are not connected to the internet, the app will try to load from the last cached data - assuming this data exist."
delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alert show];
[alert release];
}
//textField.text= statusString;
}
- (void) updateInterfaceWithReachability: (Reachability*) curReach
{
if(curReach == hostReach)
{
//[self configureTextField: remoteHostStatusField imageView: remoteHostIcon reachability: curReach];
// NetworkStatus netStatus = [curReach currentReachabilityStatus];
// BOOL connectionRequired= [curReach connectionRequired];
[self configureTextField:curReach];
}
}
Yes, Apple has an example project that shows that. Reachability
And here's an example.
Hi to all of stackoverflow,
i'm Italian so, i'm sorry for my bad English... :D
i tried to create a simple tableView for listing a few names and a number... all with core data.
- (void)tableView:(UITableView *)tableView
didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
Track *track = [[self fetchedResultsController] objectAtIndexPath:indexPath];
if(YES == self.editing) {
UIAlertView* alert = [[UIAlertView alloc] initWithTitle:#"Modifica nome" message:#"Prego, inserire di seguito il nuovo nome:" delegate:self cancelButtonTitle:#"Annulla" otherButtonTitles:#"Salva", nil];
newname = [[alert addTextFieldWithValue:track.name label:#"Nome"] text];
[alert textField].autocorrectionType = UITextAutocorrectionTypeNo;
[alert show];
[alert release];
[selectedTrack release];
} else {
UIAlertView* alert = [[UIAlertView alloc] initWithTitle:#"Aggiungi minchiate" message:#"Sei sicuro di voler aggiungere una michiata a" delegate:self cancelButtonTitle:#"Annulla" otherButtonTitles:#"Salva", nil];
newname = [[alert addTextFieldWithValue:track.trackAbstract label:#"Minchiate"] text];
[alert textField].autocorrectionType = UITextAutocorrectionTypeNo;
[alert show];
[alert release];
[selectedTrack release];
}
}
I want to send the value of the textfield to my attributes that i've created first...
Need I put the code in this method?!
- (void)alertView:(UIAlertView *)alertView willDismissWithButtonIndex:(NSInteger)buttonIndex
{
if (buttonIndex != [alertView cancelButtonIndex])
{
//HERE?!
}
}
And how i can set a new value on a core data attribute?
ANY help is appreciated... Thanks in advance!
Yes, you would put the code to grab the value from the text field in the alertView:willDismissWithButtonIndex:
method. Assuming you've created a model class for that entity (which I assume you have, as I see a class called Track in your code), you can set the value of an attribute by using dot syntax:
Track.someAttribute = newValue
Or without dot syntax, it would be [Track setSomeAttribute:newValue].
Also, note that UIAlertView's addTextFieldWithValue:label: is an undocumented method, which isn't a problem if this is an app you're planning to create just for yourself, but using it in an app submitted to the App Store will likely get it rejected.
I'm sick of writing basic UIAlertView's, ie:
UIAlertView *alert = [[UIAlertView alloc] initWith...]] //etc
Instead of doing this, is it possible to put all this in a "helper" function, where I can return the buttonIndex, or whatever an alert usually returns?
For a simple helper function I guess you could feed parameters for the title, message, I'm not sure whether you can pass delegates in a parameter though, or bundle info.
In pseudo-code, it could be like this:
someValueOrObject = Print_Alert(Title="", Message="", Delegate="", Bundle="") // etc
Any help on this would be great.
Thanks
In 4.0+ you can simplify the alert code using blocks, a bit like this:
CCAlertView *alert = [[CCAlertView alloc]
initWithTitle:#"Test Alert"
message:#"See if the thing works."];
[alert addButtonWithTitle:#"Foo" block:^{ NSLog(#"Foo"); }];
[alert addButtonWithTitle:#"Bar" block:^{ NSLog(#"Bar"); }];
[alert addButtonWithTitle:#"Cancel" block:NULL];
[alert show];
See Lambda Alert on GitHub.
This is what I wrote, when I got sick of doing the same:
-(void)alert:(NSString *)title withBody:(NSString *)message firstButtonNamed:(NSString *)firstButtonName {
[self alert: title withBody: message firstButtonNamed: firstButtonName withExtraButtons: nil informing: nil];
}
-(void)alert:(NSString *)title withBody:(NSString *)message firstButtonNamed:(NSString *)firstButtonName informing:(id)delegate {
[self alert: title withBody: message firstButtonNamed: firstButtonName withExtraButtons: nil informing: delegate];
}
-(void)alert:(NSString *)title withBody:(NSString *)message firstButtonNamed:(NSString *)firstButtonName withExtraButtons:(NSArray *)otherButtonTitles informing:(id)delegate {
UIAlertView *alert = [[UIAlertView alloc]
initWithTitle: title
message: message
delegate: delegate
cancelButtonTitle: firstButtonName
otherButtonTitles: nil];
if (otherButtonTitles != nil) {
for (int i = 0; i < [otherButtonTitles count]; i++) {
[alert addButtonWithTitle: (NSString *)[otherButtonTitles objectAtIndex: i]];
}
}
[alert show];
[alert release];
}
You can't write a function that will display an alert and then return a value like a buttonIndex though, because that value-returning only occurs when the user presses a button and your delegate does something.
In other words, the process of asking a question with the UIAlertView is an asynchronous one.
I am using multiple UIAlertViews in my code as follows
-(void) myfunc
{
myAlertView1 = [[UIAlertView alloc] initWithTitle:#"Message" message:[list objectAtIndex:1] delegate:self cancelButtonTitle:#"Ok" otherButtonTitles:nil];
[myAlertView1 show];
[myAlertView1 release], myAlertView1 = nil;
{
do something
}
myAlertView = [[UIAlertView alloc] initWithTitle:#"Error" message:[list objectAtIndex:1] delegate:self cancelButtonTitle:#"Ok" otherButtonTitles:nil];
[myAlertView show];
[myAlertView release], myAlertView = nil;
}
When I run the program in simulator
I see myAlertView1 (Message) briefly and it does not waits for Ok button click
then I see myAlertView (Error) which waits for Ok button click and after that I again see myAlertView1 (Message) and it waits till OK button is clicked.
Logically I want to see myAlertView1(Message) and wait till Ok button is clicked and then see myAlertView (Error ) and wait till button is clicked.
Am I missing something here?
UIAlertView is not modal as one might expect. You should wait for your delegate to recieve alertView:didDismissWithButtonIndex: before creating and showing the second UIAlertView
Here is how you can make your dialog modal.
I ran into this while researching a similar question from a MonoTouch/C# user, so I wrote this sample for him. The same sample can be trivially ported to Objective-C.
To do this, what you can do is to run the mainloop manually. I have not managed to stop the mainloop directly, so I instead run the mainloop for 0.5 seconds and wait until the user responds.
The following function shows how you could implement a modal query with the above approach:
int WaitForClick ()
{
int clicked = -1;
var x = new UIAlertView ("Title", "Message", null, "Cancel", "OK", "Perhaps");
x.Show ();
bool done = false;
x.Clicked += (sender, buttonArgs) => {
Console.WriteLine ("User clicked on {0}", buttonArgs.ButtonIndex);
clicked = buttonArgs.ButtonIndex;
};
while (clicked == -1){
NSRunLoop.Current.RunUntil (NSDate.FromTimeIntervalSinceNow (0.5));
Console.WriteLine ("Waiting for another 0.5 seconds");
}
Console.WriteLine ("The user clicked {0}", clicked);
return clicked;
}
Here you can do it as follows:
-(void) myfunc
{
myAlertView1 = [[UIAlertView alloc] initWithTitle:#"Message" message:[listobjectAtIndex:1] delegate:self cancelButtonTitle:#"Ok" otherButtonTitles:nil];
[myAlertView1 show];
[myAlertView1 release], myAlertView1 = nil;
{
do something
}
}
And when you get alertview, you can click OK button which calls another method to open another alertview.
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if(buttonIndex==0)
{
[self open_secondAlert];
}
}
-(void)open_secondAlert
{
myAlertView = [[UIAlertView alloc] initWithTitle:#"Error" message:[list objectAtIndex:1] delegate:self cancelButtonTitle:#"Ok" otherButtonTitles:nil];
[myAlertView show];
[myAlertView release], myAlertView = nil;
}
Please let me know if you still have any questions.
Thanks,
Best Regards,
