I have troubles when I perform a UIAlertView, (the alert view works fine) but... i cannot perform the segue to another window... the type of transition is modal... any help?
if([txtPeticion hasText] )
{
alertaVeladora = [[UIAlertView alloc]
initWithTitle:#"Santuario Virtual"
message:#"Gracias por compartir tu veladora!"
delegate:self
cancelButtonTitle:nil
otherButtonTitles:nil];
[alertaVeladora show];
[self postMessage:txtPeticion.text shareTw:shareTwitter shareFb:shareFacebook withEmail:email];
txtPeticion.text = #"";
[self performSelector:#selector(dismissAlert:) withObject:alertaVeladora afterDelay:1.0f];
}
If I understand correctly, you want to perform the segue when the user presses the dismiss button on the AlertView? To perform an action when the button has been pressed, use the following code:
if([txtPeticion hasText] )
{
alertaVeladora = [[UIAlertView alloc]
initWithTitle:#"Santuario Virtual"
message:#"Gracias por compartir tu veladora!"
delegate:self
cancelButtonTitle:nil
otherButtonTitles:nil];
[alertaVeladora show];
}
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if(alertView.tag == 1)
{
// Perform Segue
[self performSegueWithIdentifier: #"MySegue" sender: self];
}
}

Yes, I've already Googled this question and I've used the exact code, but that's still not working.
Here is my current Objective-C code:
- (IBAction)btnTemp:(id)sender
{
if (_deepSwitch.on == TRUE)
{
[self TempCleaner];
_progress.progress += 1;
}
UIAlertView *cleaned = [[UIAlertView alloc] initWithTitle:#"Done!" message:#"Your device is now clean. Restarting SpringBoard." delegate:nil cancelButtonTitle:#"Ok" otherButtonTitles:nil, nil];
[cleaned show];
}
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
if (buttonIndex == [alertView cancelButtonIndex]) {
NSLog(#"clicked");
}
}
Why isn't this working? I've tried buttonIndex 0, and cancel button!
Set the alert view's delegate to self
UIAlertView *cleaned = [[UIAlertView alloc] initWithTitle:#"Done!" message:#"Your device is now clean. Restarting SpringBoard." delegate:self cancelButtonTitle:#"Ok" otherButtonTitles:nil, nil];
Also, make sure that the class from which you are presenting the alert view declares the UIAlertViewDelegate protocol
//YourClass.h
#interface YourClass : SuperClass <UIAlertViewDelegate>
How can i assign an action for close button in my window in objective-c?
For example, user clicks on close button and then program asks: "Do you really want to close the window?"
If you want to add message before closing view in Application you need to implement UIAlertView in it, don't forget to add < UIAlertViewDelegate> in .h file
code in action button pressed;
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Message"
message:#"Do you really want to close the window?"
delegate:self
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alert show];
If you want to do something when the button is clicked, implement this delegate method:
- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex {
// the user clicked OK
if (buttonIndex == 0) {
// Write Close Code here.....
}
}
Define an uialertview
UIAlertView *message;
message= [[UIAlertView alloc] initWithTitle:#"LOGOUT!" message:#"Are you sure to Logout of This app?" delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
case :
{
[message show];
vc = [mainStoryboard instantiateViewControllerWithIdentifier:#"loginVC"];
[[SlideNavigationController sharedInstance] popAllAndSwitchToViewController:vc withCompletion:nil];
break;}
}
default:
break;
}
I want two alert views to show up only when the user opens my application for the first time -- the second to appear after the first is dismissed. I have it set up to only show the UIAlertViews when it has not been shown before and I do not need help with this. I need help figuring out how to display two alert views in a row when this is the case.
-(void) alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex does not work for me.
Here is the code I have -- remember this is in didFinishLaunchingWithOptions:
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
BOOL didFirstLaunch = [defaults boolForKey:#"DidFirstLaunch"];
if (!didFirstLaunch) {
[defaults setBool:YES forKey:#"DidFirstLaunch"];
UIAlertView *successAlert = //not important
[successAlert show];
[successAlert release];
//Somehow show second alert after the first is dismissed
}
I'm gonna post a very simple solution using GCD & blocks (GCD part is just in case the alert view is created on another thread then the main thread, callback should be safe to perform on the main thread). Remember, I just coded this in like 5 mins, so you definitely should work on improving the code. One thing that's a bit ugly is the delegate parameter that is overridden in my subclass. The interface of the subclass could be changed a bit to make it more obvious of what happens ...
Anyway, here goes ...
First create a subclass of UIAlertView, make it look somewhat like the following ...
#interface FSAlertView () <UIAlertViewDelegate>
#property (nonatomic, copy) void (^dismissHandler)(NSInteger buttonIndex);
#end
#implementation FSAlertView
#synthesize dismissHandler = _dismissHandler;
- (void)showWithDismissHandler:(void (^)(NSInteger buttonIndex))dismissHandler
{
self.dismissHandler = dismissHandler;
self.delegate = self;
[self show];
}
// Alert view delegate
- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex
{
dispatch_async(dispatch_get_main_queue(), ^ {
if (_dismissHandler)
{
_dismissHandler(buttonIndex);
}
});
}
Now in the app we can create alert views like the following ...
FSAlertView *alert1 = [[FSAlertView alloc] initWithTitle:#"Alert 1"
message:#"Some message"
delegate:nil
cancelButtonTitle:#"Cancel"
otherButtonTitles:#"Show 2nd Alert", nil];
[alert1 showWithDismissHandler:^ (NSInteger buttonIndex) {
NSLog(#"button pressed: %d", buttonIndex);
if (buttonIndex == 1)
{
UIAlertView *alert2 = [[UIAlertView alloc] initWithTitle:#"Alert 2"
message:#"Hi!"
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alert2 show];
}
}];
If i understand your question correctly , then this may help:
UIAlertView *firstAlert = [[UIAlertView alloc] initWithTitle:#"Alert 1" message:nil delegate:self cancelButtonTitle:nil otherButtonTitles:nil, nil];
[firstAlert show];
[self performSelector:#selector(test:) withObject:firstAlert afterDelay:2];
[firstAlert release];
UIAlertView *secondAlert = [[UIAlertView alloc] initWithTitle:#"Alert 2" message:nil delegate:self cancelButtonTitle:nil otherButtonTitles:nil, nil];
[secondAlert show];
[self performSelector:#selector(test:) withObject:secondAlert afterDelay:2];
[secondAlert release];
-(void)test:(UIAlertView*)alert{
[alert dismissWithClickedButtonIndex:-1 animated:YES];
}
This will show two alert views one after the other.
NOTE: I am not sure if you are dismissing the alerts with cancel button so i am dismissing them automatically after few seconds.
Try this:
UIAlertView *firstAlert = [[UIAlertView alloc] initWithTitle:#"Title" message:#"Message" delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:#"Ok", nil];
[firstAlert setTag:444];
[firstAlert show];
firstAlert = nil;
AlertView Delegate Method:
- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex
{
switch (alertView.tag) {
case 444:
{
//Cancel ButtonIndex = 0
if (buttonIndex == 1) {
UIAlertView *secondAlert = [[UIAlertView alloc] initWithTitle:#"Title 2" message:#"Message2" delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:#"Dismiss", nil];
[secondAlert setTag:555];
[secondAlert show];
secondAlert = nil;
}
}
break;
case 555:
{
if (buttonIndex == 1) {
NSLog(#"Code Here");
}
}
break;
}
}
Hi guys i have this i IBAction linked to a button:
- (IBAction)showCurl:(id)sender {
alert1 = [[UIAlertView alloc]initWithTitle:#"Loading" message:nil delegate:self cancelButtonTitle:nil otherButtonTitles:nil];
[alert1 show];
}
and a clickedButtonIndex to auto run but somehow it doesn't load SecondViewController:
#pragma mark UIAlertView
- (void)alertView:(UIAlertView *)alert1 clickedButtonAtIndex:(NSInteger)buttonIndex {
if(buttonIndex == 0){
SecondViewController *sampleView = [[SecondController alloc] init];
[sampleView setModalTransitionStyle:UIModalTransitionStylePartialCurl];
[self presentModalViewController:sampleView animated:YES];
}
else{
// Cancel prompt
}
}
Am i missing something here?
If you don’t give the alert view some button titles, there won’t be any buttons to tap on and that delegate method won’t get called.
- (IBAction)showCurl:(id)sender {
alert1 = [[UIAlertView alloc] initWithTitle:#"Loading" message:nil delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alert1 show];
}
Your code doesn't show a button
alert1 = [[UIAlertView alloc]initWithTitle:#"Loading" message:nil delegate:self cancelButtonTitle:**nil** otherButtonTitles:**nil**];
You pass nil as cancelButtonTitle AND nil as otherbuttonTitles, you should at least have one button title set.
i am using ASIHttpRequest in my iOS project. In the requestFail i am doing like this :
#pragma mark Erreur requête de connexion
- (void)requestFailed:(ASIHTTPRequest *)request
if([[request error] code] == ASIConnectionFailureErrorType )
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Erreur de connexion"
message:#"Connexion avec le serveur impossible : vérifiez vos paramètres réseaux."
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alert show];
}
else if ([[request error] code] == ASIRequestTimedOutErrorType)
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Erreur de connexion"
message:#"La requête a expiré !"
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alert show];
}
else
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Erreur de connexion"
message:#"Une erreur inconnue est survenue."
delegate:nil
cancelButtonTitle:#"Annuler"
otherButtonTitles:nil];
[alert show];
}
}
Now, i would like to replace all my UIAlertView with an imageView ( show to the user a special UIImageView to tell him that there is an error ( connexion failure....), and remove this imageView when there is not server error.
Resume : I would like to show an imageView when the request fail and remove this image view and relance the request ( How I can do this with ASIHtppRequest) ?
I think you can use a UIActionSheet to replace the UIAlertView because the ActionSheet can be handled like a UIView, so you can present the ActionSheet that contains your UIImageView. You can also use one of the buttons to dismiss the ActionSheet to reload your ASIHTTPRequest.
The following code shows you the UIActionSheet's delegate methods that allow you to add your UIImageView and trigger your request when the cancel button is clicked.
#pragma -
#pragma ActionSheet Delegate
- (void)willPresentActionSheet:(UIActionSheet *)actionSheet {
UIImageView * yourImageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 55, 320, 100)];
//Configure yourImageView...
//Add picker to action sheet
[actionSheet addSubview:yourImageView];
// Release your yourImageView
[yourImageView release];
}
- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
if (buttonIndex != [actionSheet cancelButtonIndex])
{
// Call back your ASIHTTPRequest
}
}
Don't forget to implement the UIActionSheetDelegate in your .h file.
Good luck.
