alright so i have a small problem here, i have this here.
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if (buttonIndex == 0)
{
//YES clicked ...do your action
[self.parentViewController dismissModalViewControllerAnimated:YES];
}
else if (buttonIndex == 1)
{
//NO clicked
return;
}
}
This Allows me to capture events triggered from UIAlertView Buttons but i have assigned it a value and on the same page i need another value to be assigned to that class so:
if(buttonIndex == 2){//Proceed}
i mainly want it so that when the button is pushed on my second alert it will go back to the processes it was doing and not proceed with the event of (buttonIndex == 0).
So Does anyone know Where i could start?
Just store a reference in you .h file of the 2 UIAlertView's, and then do a check. For instance, in your .h file:
UIAlertView * alertView1;
UIAlertView * alertView2;
In your .m file, set up your UIAlertView's in you viewDidLoad method, and change the alertView:clickedButtonAtIndex: method to:
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex; {
if (alertView == alertView1) {
// Do what you want the alertView1 to do here.
if (buttonIndex == 0) {
//YES clicked ...do your action
[self.parentViewController dismissModalViewControllerAnimated:YES];
}
else if (buttonIndex == 1) {
}// etc.
}
else if (alertView == alertView2) {
// Do what you want the alertView2 to do here.
}
}
Hope that Helps!
Something else you can do is use the alertView tag in case you have multiple alertviews in your app. For instance, you could do something like this:
UIAlertView *alert1 = [[UIAlertView alloc] initWithTitle:#"Title" message:#"AThe message." delegate:self cancelButtonTitle:#"button 1" otherButtonTitles: #"button 2", nil];
alert1.tag = 0;
[alert1 show];
[alert1 release];
Then in your delegate method, simply put the following if clause:
if (alertView == alertView1)
before your code above.
If you don't figure this out, you could place a counter in the program that counts the number of times the alertview had been triggered, and then act upon that value.

I am trying to work out how I can use a UIAlertView to do more than one command.
Basically, in my ViewController, there is already an alertView, however I am now adding some storekit files, which, require there own alertView (to tell it whether to purchase the in-app or cancel etc.
Here is original alertView code;
- (void) alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
[alertView dismissWithClickedButtonIndex:0 animated:NO];
if (buttonIndex == 1) {
[g_GameUtils removeAlbumFolder:deleteIndex];
[g_GameUtils readAllData];
[g_GameUtils getAlbumFolderList];
[m_pTable reloadData];
}
}
And here is what I need also - they are both called alertView so I cannot use both like this, is there a way to combine them? Or is it better to call one of them alertView2 ? If so, how does it know which one to call for the particular alert?
Thanks in advance!

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if (buttonIndex == 0){
//cancel button clicked. Do something here or nothing here
}
else{
//other button indexes clicked
[[MKStoreManager sharedManager] buyFeature:#"com.davis.apptoken.buy"];
}
}
Also you can use alertView.tag = 1; and alertView2.tag = 2; and add appropriate conditions to delegate:
if (alertView.tag == 1)
{
// First alert
}
I'm sort of stuck on a UIAlertViewStylePlainTextInput. (My code is too long to post here, but this is the part where the problem exists.) It all sort of works, but the program doesn't wait until the user enters the information before continuing. The "editName" button doesn't change the display in the code below, but the updateDisplay button works fine (if you've pressed the "editName" button before you pressed "updateDisplay"). How can I get everything to sort of halt until the user enters the info (or cancels). Or is there some other lead that will take me where I need to go. (I've been toying with putting the rest of the code in the -(void) alertView, but that just doesn't seem to be the correct way of doing it).
Thanks in advance.
#import "HSTestViewController.h"
#implementation HSTestViewController
#synthesize display;
NSString *newName;
- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex
{
if (buttonIndex == 1)
{
newName = [[alertView textFieldAtIndex:0] text];
}
}
- (void) getNewName;
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"You made the High Score List"
message:#"Please enter your name"
delegate:self
cancelButtonTitle:#"Cancel"
otherButtonTitles:#"Ok", nil];
alert.alertViewStyle = UIAlertViewStylePlainTextInput;
[alert show];
}

{
[self getNewName];
newName = display.text;

Add UIAlertViewDelegate to the class. And implement the below delegate method.
OK button index value will be 1 in your case.
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if (buttonIndex)
{
// call the method or the stuff which you need to perform on click of "OK" button.
}
}
Hope this helps.
I'm writing a puzzle game. When the user presses the check button, I see if the solution they entered is correct. Depending on the result, I present one of two action sheets for them. For now I just have some NSLog statements to make sure things are getting called, but only one of the sheets seems to work properly.
Nothing gets called when I click a button in showErrorsActionSheet. The action sheet disappears off the screen, but the logs never print.
I suspect it has something to do with having two actionsheets declared to the same delegate (self)
- (void) checkSolution {
//code determines the value of the BOOL allCorrect
if (allCorrect) { //IF ALL OF THE LETTERS WERE CORRECT
//display UIAlertView;
NSLog(#"allCorrect");
UIActionSheet *levelCompleteActionSheet = [[UIActionSheet alloc] initWithTitle:#"Congratulations! You Have Finished the Level!" delegate:self cancelButtonTitle:#"Review my work" destructiveButtonTitle:#"Choose next puzzle" otherButtonTitles:nil, nil];
[levelCompleteActionSheet showInView:self.view];
[levelCompleteActionSheet release];
}
else {
//[self showIncorrectLettersInRed];
UIActionSheet *showErrorsActionSheet = [[UIActionSheet alloc] initWithTitle:#"Sorry, thats not right. Show errors in red?" delegate:self cancelButtonTitle:#"No Thanks, I'll keep trying" destructiveButtonTitle:#"Yes please, I'm stuck!" otherButtonTitles:nil, nil];
[showErrorsActionSheet showInView:self.view];
[showErrorsActionSheet release];
}
}
the methods that are supposed to be called are:
- (void) levelCompleteActionSheet:(UIActionSheet *)actionSheet didDismissWithButtonIndex:(NSInteger)buttonIndex {
if (buttonIndex != [actionSheet cancelButtonIndex]) {
NSLog(#"return to levelSelect");
//pushViewController:levelSelect
}
else {
NSLog(#"continue to examine solution");
}
}
- (void) showErrorsActionSheet:(UIActionSheet *)actionSheet didDismissWithButtonIndex:(NSInteger)buttonIndex {
if (buttonIndex != [actionSheet cancelButtonIndex]) {
NSLog(#"show errors in red");
}
else {
NSLog(#"continue to try");
}
}
and Ive declared the UIActionSheet protocol in the interface file as follows:
#interface GamePlay : UIViewController <UIActionSheetDelegate> {
Set a tag for each actionSheet, then use a switch statement in the UIActionSheet delegate.
Assign a tag
- (void)checkSolution
{
if (allCorrect)
{
UIActionSheet *levelCompleteActionSheet = [[UIActionSheet alloc] initWithTitle:#"Congratulations! You Have Finished the Level!" delegate:self cancelButtonTitle:#"Review my work" destructiveButtonTitle:#"Choose next puzzle" otherButtonTitles:nil, nil];
[levelCompleteActionSheet setTag: 0];
[levelCompleteActionSheet showInView:self.view];
[levelCompleteActionSheet release];
}
else
{
UIActionSheet *showErrorsActionSheet = [[UIActionSheet alloc] initWithTitle:#"Sorry, thats not right. Show errors in red?" delegate:self cancelButtonTitle:#"No Thanks, I'll keep trying" destructiveButtonTitle:#"Yes please, I'm stuck!" otherButtonTitles:nil, nil];
[showErrorsActionSheet setTag: 1];
[showErrorsActionSheet showInView:self.view];
[showErrorsActionSheet release];
}
}
UIActionSheet Delegate
- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
switch ( actionSheet.tag )
{
case 0: /* levelCompleteActionSheet */
{
switch ( buttonIndex )
{
case 0: /* 1st button*/
break;
case 1: /* 2nd button */
break;
}
}
break;
case 1: /* showErrorsActionSheet */
break;
}
}
The same would apply anywhere else in this class as well, including levelCompleteActionSheet: and showErrorsActionSheet:. The only difference is, you would need to create an iVar for each actionSheet instead of creating them in checkSolution.
The methods that will be called by a UIActionSheet on its delegate are the methods listed in the UIActionSheetDelegate protocol.
http://developer.apple.com/library/ios/#documentation/uikit/reference/UIModalViewDelegate_Protocol/UIActionSheetDelegate/UIActionSheetDelegate.html
To be called, your method must be one of those methods. I don't see levelCompleteActionSheet or showErrorsActionSheet listed in that protocol! :) Your method must be named actionSheet:clickedButtonAtIndex:, and not some name you make up out of whole cloth.
Using Tag solve this problem
levelCompleteActionSheet.tag = 100;
showErrorsActionSheet.tag = 101;
- (void) levelCompleteActionSheet:(UIActionSheet *)actionSheet didDismissWithButtonIndex:(NSInteger)buttonIndex {
if(actionSheet.tag == 100){
// levelCompleteActionSheet implement your required function
}
else if(actionSheet.tag == 101){
// showErrorsActionSheet implement your required function
}
}
-(void) buttonClick:(id) sender
{
action=[[UIAlertView alloc] initWithTitle:nil message:#"Confirm for action" delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:nil];
[action addButtonWithTitle:#"Yes"];
[action show];
[action release];
}
- (void)alertView:(UIAlertView *)action didDismissWithButtonIndex:(NSInteger)buttonIndex {
if (buttonIndex == 1) {
[self func1];
}
else if (buttonIndex ==0) //cancel
{
}
}
instead of executing func1 when clicked Yes on alertview, the app pop up a registration form from my registration page in the app.
set a break point on "if (buttonIndex == 1) " and follow the code using step into button. the problem should be somewhere else in your program.
i need to show a confirm alert after the user press buttonIndex 1 but... if i use popViewcontroller in clickedButtonAtIndex it crash without errors.
The problem is that
[self.navigationController popViewControllerAnimated:YES];
is called before second Alert click...
how to fix?
This is my code:
- (void) alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
if (buttonIndex == 1) {
UIAlertView *alert =
[[UIAlertView alloc] initWithTitle:#"OK!"
message:#"Completed"
delegate:self
cancelButtonTitle:#"OK" otherButtonTitles:nil, nil];
[alert show];
[alert release];
[self.navigationController popViewControllerAnimated:YES];
}
}
Set the tag properties of the two UIAlertViews to 1 and 2, respectively. Then, in the delegate method, use if statements to check the tag of the UIAlertView argument.
Example:
- (void) alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if (alertView.tag == 1)
{
//check the button index
//create and display the other alert view (set the tag property here to 2)
}
else if (alertView.tag == 2)
{
//pop the view controller
}
}
