How can I add an alert that displays instructions before game starts:
See code below:
- (void)viewDidLoad
{
[super viewDidLoad];
if (questions && configDictionary) {
[questionLabel setText:[[questions objectAtIndex:currentQuestonIndex] objectForKey:#"question"]];
NSArray *answers = [[questions objectAtIndex:currentQuestonIndex] objectForKey:#"answers"];
[answerLabel0 setText:[answers objectAtIndex:0]];
[answerLabel1 setText:[answers objectAtIndex:1]];
[answerLabel2 setText:[answers objectAtIndex:2]];
[answerLabel3 setText:[answers objectAtIndex:3]];
[pointsPerAnswerLabel setText:[NSString stringWithFormat:#"+%d points", [[configDictionary objectForKey:kPointsPerCorrectAnswer] intValue]]];
[currentQuestionNumberLabel setText:[NSString stringWithFormat:#"question %d", currentQuestonIndex+1]];
}
}
Use a UIAlertView:
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Instructions"
message:#"Your Instructions..." delegate:self cancelButtonTitle:#"Dismiss"
otherButtonTitles:nil, nil];
[alert show];
If you want to alert the user every time the app launches place it in the
- (void)applicationDidFinishLaunching:(UIApplication *)application {
}
Edit
You said you wanted to start the game after the dismiss button is pressed. So take advantage of the UIAlertView delegate:
- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex {
if (buttonIndex == 0){
//Start your game!
}
}
UIAlertView *message = [[UIAlertView alloc] initWithTitle:#"How to play"
message:#"Answer the questions correctly to get points blablabla..."
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[message show];

I have a class name viewController and it has the following code below and it works fine. However, when I call check from my subclass controller it doesn't work the way I want it to.The UIAlertView shows up, but it isn't able to detect when button index 0 is touched.Any workaround for this.
-(void)check{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"You Lose!"
message:#"Play Again?"
delegate:self
cancelButtonTitle:#"OK"
otherButtonTitles:#"OK", nil];
[alert show];
}
- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex {
if (buttonIndex == 0) { // and they clicked OK.
ViewController*myNewVC = [[ViewController alloc] init];
[self presentModalViewController:myNewVC animated:NO];
}
}
Add UIAlertViewDelegate in your subclass .h file like bellow..
#interface yourSubClassViewController :UIViewController <UIAlertViewDelegate>{
/// your code
}
#end
The Cancel button will be the index "0", Try for index==1.
Use this method:
-(void)check{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"You Lose!"
message:#"Play Again?"
delegate:self
cancelButtonTitle:#"OK"
otherButtonTitles:#"PopUp", nil];
[alert show];
}
- (void) alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
if (buttonIndex == 0) {
NSLog("Cancel Button clicked);
}
else if (buttonIndex == 1) {
ViewController*myNewVC = [[ViewController alloc] init];
[self presentModalViewController:myNewVC animated:NO];
}
Don't use cancel button. Use two buttons otherButtonTitles and use the buttons index == 1 and button index == 2 . That may help.
You need to set the delegate to your subclass.
-(void)check:(id)delegate{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"You Lose!"
message:#"Play Again?"
delegate:delegate
cancelButtonTitle:#"OK"
otherButtonTitles:#"OK", nil];
[alert show];
}
and you call it [self check:self];
In my picker view i have a "Custom" option which should popup a UIAlertView for the user to enter a new value, the value is saved in the plist source of the picker for future reference. xxxEditingDidBegin is being called repeatedly (never ending).
I presume its because my UIAlertView is triggering the picker to close.
How should I have done this?
- (IBAction)serviceTypeFieldEditingDidEnd:(UITextField *)sender
{
UIPickerView *picker = [sender.inputView.subviews objectAtIndex:0];
NSString *selText = [serviceTypeArray objectAtIndex: [picker selectedRowInComponent:0]];
sender.text = selText;
if (NSOrderedSame==[selText compare:#"Custom"])
{
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"Custom Role"
message:#"Enter Role Title"
delegate:self
cancelButtonTitle:#"Cancel"
otherButtonTitles:#"Ok", nil];
alertView.alertViewStyle = UIAlertViewStylePlainTextInput;
[alertView show];
}
}
Implement method like
- (IBAction)doSelectDate:(UIDatePicker *)sender
{
UIAlertView *alert=[[UIAlertView alloc]initWithTitle:#"Hi" message:#"AlertView is shwoing" delegate:nil cancelButtonTitle:#"Dismiss" otherButtonTitles:nil, nil];
[alert show];
[alert release];
}
and connect above method with ValueChanged Event of UIPickerView;
I fixed it like this
- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row
inComponent:(NSInteger)component
{
NSString *rowString = [serviceTypeArray objectAtIndex:row];
if ([rowString compare:#"Custom"] == NSOrderedSame)
{
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"Custom Role"
message:#"Enter Role Title"
delegate:self
cancelButtonTitle:#"Cancel"
otherButtonTitles:#"Ok", nil];
alertView.alertViewStyle = UIAlertViewStylePlainTextInput;
[alertView show];
}
else
{
_serviceType.text = rowString;
}
}
I am new to iOS.
I am working on alertviews. Here is my code. Here there are 2 alertviews: successfulallert and unsuccessfulallert for login page. I am using alertview delegate also here, it will work for both alertviews but I want to work only for successful alertview and navigation should be done only for successful alertview. If anybody knows this please help me.
NSString *responseOfResult = [[NSString alloc]initWithString:[result response]];
NSRange match;
// NSLog(#"string= %#", str);
match = [responseOfResult rangeOfString: #"successful"];
if(match.location == NSNotFound)
{
UIAlertView *unsuccessfulAllert = [[UIAlertView alloc]
initWithTitle:#"Alert"
message:responseOfResult
delegate:self
cancelButtonTitle:nil otherButtonTitles:#"OK", nil];
[unsuccessfulAllert show];
}
else {
UIAlertView *successfulAllert = [[UIAlertView alloc]
initWithTitle:#"Message" message:#"Login successful." delegate:self cancelButtonTitle:nil otherButtonTitles:#"OK", nil];
[successfulAllert show];
}
-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
if(buttonIndex == 0){
[[self navigationController]pushViewController:registerUserScreen animated:YES];
}
}
Why don't you put "OK" as cancelButtonTitle? Everything will be handled automatically.
UIAlertView *successfulAllert = [[UIAlertView alloc]
initWithTitle:#"Message" message:#"Login successful." delegate:self cancelButtonTitle:#"Ok" otherButtonTitles:nil, nil];
[successfulAllert show];
-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
if(buttonIndex == 0){
//POP here with this:
[self.navigationController pushViewController:addItemView animated:NO];
}
}
NSString *responseOfResult = [[NSString alloc]initWithString:[result response]];
NSRange match;
// NSLog(#"string= %#", str);
match = [responseOfResult rangeOfString: #"successful"];
if(match.location == NSNotFound)
{
UIAlertView *unsuccessfulAllert = [[UIAlertView alloc]
initWithTitle:#"Alert"
message:responseOfResult
delegate:self
cancelButtonTitle:nil otherButtonTitles:#"OK", nil];
[unsuccessfulAllert setTag:1];
[unsuccessfulAllert show];
}
else {
UIAlertView *successfulAllert = [[UIAlertView alloc]
initWithTitle:#"Message" message:#"Login successful." delegate:self cancelButtonTitle:nil otherButtonTitles:#"OK", nil];
[successfulAllert setTag:2];
[successfulAllert show];
}
-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
if(alertView.tag == 2)
{
[[self navigationController]pushViewController:registerUserScreen animated:YES];
}
else
{
//[[self navigationController]pushViewController:registerUserScreen animated:NO];
// OR
return;
}
}
You have many ways to correct your code, the first and very common is to use the tag property (integer) of the UIView. Since UIAlertview inherits from UIView, it has the tag property, so each time you want create an alert (or a view), set the tag and the check your condition like:
...
alert.tag=1;
[alert show];
then to know wich alert is calling the callback:
-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
if(alertView.tag==theTagOfYourAlert){
//do your stuff
}
}
another way, in your case, could be:
if([alertView.title isEqualToString:#"Alert"]){
//do your stuff
}
}
Add tag to the two alert views and check for tag in alert view delegate.
Sample code:
NSString *responseOfResult = [[NSString alloc]initWithString:[result response]];
NSRange match;
// NSLog(#"string= %#", str);
match = [responseOfResult rangeOfString: #"successful"];
if(match.location == NSNotFound)
{
UIAlertView *unsuccessfulAllert = [[UIAlertView alloc]
initWithTitle:#"Alert"
message:responseOfResult
delegate:self
cancelButtonTitle:nil otherButtonTitles:#"OK", nil];
[unsuccessfulAllert setTag:1];
[unsuccessfulAllert show];
}
else {
UIAlertView *successfulAllert = [[UIAlertView alloc]
initWithTitle:#"Message" message:#"Login successful." delegate:self cancelButtonTitle:nil otherButtonTitles:#"OK", nil];
[successfulAllert setTag:2];
[successfulAllert show];
}
-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
if(alertView.tag==2 && buttonIndex == 0){
[[self navigationController]pushViewController:registerUserScreen animated:YES];
}
Yes the delegate would work for both the alertviews but you can assign a tag to each alertview Object and check for the tag in the delegate and then perform event if the tag for that particular AlertView onject matches.If u need code , i will provide.
For things like Login status updates, you might want to have the "Login Successful" message disappear automatically. Try this instead:

This works nicely and comes in handy for situations like this. Plus you don't have to deal with all the clutter involved with UIAlertViews.
Hi here i developing small application. In a subclass screen i have two buttons. When i press the first button, it will shows four actionsheet. When i press second button it wil shows five actionsheet. I was successfully shows it. But i cant set second button actions of five actionsheet. In my code the when i press second button of first actionsheet, it wil actioned first button of first actionsheet. Here i want set actions for individual actionsheets. Pls help me. Here is my code is
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
if ( indexPath.row == 0)
{
UIActionSheet *popupQuery = [[UIActionSheet alloc] initWithTitle:nil delegate:self cancelButtonTitle:#"Cancel" destructiveButtonTitle:#"Edit" otherButtonTitles:#"Remove", #"Sell",#"Scrap", nil];
popupQuery.actionSheetStyle = UIActionSheetStyleBlackTranslucent;
[popupQuery showInView:self.view];
[popupQuery release];
}
if ( indexPath.row == 1 )
{
UIActionSheet *popupQuery = [[UIActionSheet alloc] initWithTitle:nil delegate:self cancelButtonTitle:#"Cancel" destructiveButtonTitle:#"Unsell" otherButtonTitles:#"Edit Item", #"Edit Sale",#"Sold",#"Scrap", nil];
popupQuery.tag=5;
popupQuery.actionSheetStyle = UIActionSheetStyleBlackOpaque;
[popupQuery showInView:self.view];
[popupQuery release];
}
}
-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
if (buttonIndex == 0)
{
Updateasset *object=[[Updateasset alloc]initWithNibName:#"Updateasset" bundle:nil];
[self presentModalViewController:object animated:NO];
[object release];
}
else if (buttonIndex == 1)
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Remove" message:#"Do you want to Remove"
delegate:self cancelButtonTitle:#"No" otherButtonTitles:#"Yes", nil];
[alert show];
[alert release];
}
else if (buttonIndex == 2)
{
Egarageselling *object=[[Egarageselling alloc]initWithNibName:#"Egarageselling" bundle:nil];
[self presentModalViewController:object animated:YES];
[object release];
}
else if (buttonIndex == 3)
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Scrap" message:#"Do you want to Scrap"
delegate:self cancelButtonTitle:#"No" otherButtonTitles:#"Yes", nil];
[alert show];
[alert release];
}
else if (buttonIndex == 4)
{
}
else if (buttonIndex == 5)
{
}
else if (buttonIndex == 6)
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Scrap" message:#"Do you want to Scrap"
delegate:self cancelButtonTitle:#"No" otherButtonTitles:#"Yes", nil];
[alert show];
[alert release];
}
else if (buttonIndex == 7)
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Scrap" message:#"Do you want to Scrap"
delegate:self cancelButtonTitle:#"No" otherButtonTitles:#"Yes", nil];
[alert show];
[alert release];
}
else if (buttonIndex == 8)
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Scrap" message:#"Do you want to Scrap"
delegate:self cancelButtonTitle:#"No" otherButtonTitles:#"Yes", nil];
[alert show];
[alert release];
}
else if (buttonIndex == 9)
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Scrap" message:#"Do you want to Scrap"
delegate:self cancelButtonTitle:#"No" otherButtonTitles:#"Yes", nil];
[alert show];
[alert release];
}
}
How to solve this problem.
Set different tags for two actionsheets like
popupQuery.tag=5;
popupQuery.tag=6;
-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
if(actionSheet.tag==5)
{
if (buttonIndex == 0)
{
}
so on
}
if(actionSheet.tag==6)
{
if (buttonIndex == 0)
{
}
so on
}
}
I might just add, that in a situation like this I would say that best practice is to make your actionsheet to public or private instance variables. It would look like this in your header file (for public):
#property (nonatomic, retain) UIActionSheet *as1;
#property (nonatomic, retain) UIActionSheet *as2;
In your implementation file you synthesize them, like this:
#synthesize as1, as2;
Then remember to set them from where you now allocate your popupQuery's today:
...
self.as1 = popupQuery;
...
...
self.as2 = popupQuery;
...
And in your delegate method you can now do it like this (which I also find more readable if I should ever present the code for another developer):
-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
if(self.as1 == actionSheet) {
if (buttonIndex == 0) { ... }
...
}
if(self.as2 == actionSheet) {
if (buttonIndex == 0) { ... }
...
}
}
I hope you find it useful in this and many other cases. I myself, do it like that, all the time. No harm in having a public or private reference for that matter to you objects. You never know when they might come in handy.
my app needs alert msg and if yes button pressed then one more alert msg and then i have to called a method.This is my code:
-(IBAction)resetPressed:(id)sender
{
NSString *title= [NSString stringWithFormat:#"Warning"];
NSString *message = [NSString stringWithFormat:#"Are you sure you want to Reset"];
NSString *ok = [NSString stringWithFormat:#"No"];
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title
message:message
delegate:self
cancelButtonTitle:ok otherButtonTitles:#"Yes",nil];
[alert show];
[alert release];
}
- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex
{
if (alertView.tag ==1)
{
NSString *title= [NSString stringWithFormat:#"Warning"];
NSString *message = [NSString stringWithFormat:#"Are you sure you want to Reset"];
NSString *ok = [NSString stringWithFormat:#"No"];
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title
message:message
delegate:self
cancelButtonTitle:ok otherButtonTitles:#"Yes",nil];
alert.tag =2;
[alert show];
[alert release];
}
else if(alertView.tag ==2)
{
[self resetArray];
}
}
Thanks.
I'm not sure what your goal is but a few things look wrong to me anyways:
First of all you should create your strings this way:
NSString *title= #"Warning";
There's no need to use stringWithFormat in your case.
Then, it doesn't seem you properly set the first UIAlert's tag to 1, and the default value for tags is 0 so I guess the if statements in didDismissWithButtonIndex are never true.
Also, you should check which button was pressed using buttonIndex, otherwise you are going to show both alert and call [self resetArray] whichever button is pressed by the user.
Hope that helps.
In your code, you create the first alert, but never actually set the tag on it. You should do:
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title
message:message
delegate:self
cancelButtonTitle:ok otherButtonTitles:#"Yes",nil];
alert.tag = 1; //Or 2, or something.
[alert show];
[alert release];
Then the code in your delegate method will run.
Please define two separate UIAlertView in .h file
#interface XYZViewController:UIViewController
{
UIAlertView *firstAlertView;
UIAlertView *secondAlertView;
}
Now in your .m file modify as below:
-(IBAction)resetPressed:(id)sender
{
NSString *title= [NSString stringWithFormat:#"Warning"];
NSString *message = [NSString stringWithFormat:#"Are you sure you want to Reset"];
NSString *ok = [NSString stringWithFormat:#"No"];
if(firstAlertView == nil)
{
firstAlertView = [[UIAlertView alloc] initWithTitle:title message:message delegate:self cancelButtonTitle:ok otherButtonTitles:#"Yes",nil];
}
[firstAlertView show];
}
- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex
{
if (alertView == firstAlertView)
{
NSString *title= [NSString stringWithFormat:#"Warning"];
NSString *message = [NSString stringWithFormat:#"Are you sure you want to Reset"];
NSString *ok = [NSString stringWithFormat:#"No"];
if(secondAlertView == nil)
{
secondAlertView = [[UIAlertView alloc] initWithTitle:title message:message delegate:self cancelButtonTitle:ok otherButtonTitles:#"Yes",nil];
}
[secondAlertView show];
}
else if(alertView == secondAlertView)
{
[self resetArray];
}
}
and in dealloc method please release the allocated UIAlertviews.
Hope i am clear to you.
Thanks,
Jim.
