I would insert an UIAlert in an IBAction when I press a button, how can I do? This UIAlert must show message "Done" and a button to close it.
- (IBAction)onShowAlertView
{
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"done"
message:#""
delegate:nil
cancelButtonTitle:#"close"
otherButtonTitles:nil];
[alertView show];
[alertView release];
}

I experiment at the moment with some alertViews. Now try to set an AlertView with two textField`s. When I click "done" it should show a Log.
At the moment, the code looks like that:
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Titel" message:#"Message" delegate:self cancelButtonTitle:#"Done" otherButtonTitles:#"Cancel", nil];
The TextField should have placeholder. How do I set it up?
Try this: it should work:
UIAlertView *av = [[UIAlertView alloc] initWithTitle:#"Your_Title" message:#"Your_message" delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:#"OK", nil];
[av setAlertViewStyle:UIAlertViewStyleLoginAndPasswordInput];
// Alert style customization
[[av textFieldAtIndex:1] setSecureTextEntry:NO];
[[av textFieldAtIndex:0] setPlaceholder:#"First_Placeholder"];
[[av textFieldAtIndex:1] setPlaceholder:#"Second_Placeholder"];
[av show];
You can access the values of the text fields on the alertView:clickedButtonAtIndex: of UIAlertViewDelegate.
-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
NSLog(#"1 %#", [alertView textFieldAtIndex:0].text);
NSLog(#"2 %#", [alertView textFieldAtIndex:1].text);
}
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 am trying to create an AlertView which does not have a cancel button.
This is the code I have tried:
alertView.cancelButtonIndex = -1;
It does not seem to work with iOS 7.
Any ideas?
Thanks,
1) With using this code pressing "Do something button" can do some action but will not lead to alertView hiding
UIAlertView *alert = [[[UIAlertView alloc] initWithTitle:#"Title" message:#"The message." delegate:self cancelButtonTitle:nil otherButtonTitles: #"Do something", nil] show];
#pragma mark - UIAlertViewDelegate
- (BOOL)alertViewShouldEnableFirstOtherButton:(UIAlertView *)alertView {
return NO;
}
2) With using this code there will be no buttons on the alertView(I think this is what you actually need)
UIAlertView *alert = [[[UIAlertView alloc] initWithTitle:#"Title" message:#"The message." delegate:self cancelButtonTitle:nil otherButtonTitles:nil] show];
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 was just curious about how can i attach some different task to the otherButtonTitle of UIAlertView.
The cancel button automatically take you out of the application but if i want to attach a different task with the otherButtonTitle ,what should i do?
Thanks,
UIAlertView delegate "didDismissWithButtonIndex" get called every time u click any button.
Try this:
UIAlertView* alert = [[UIAlertView alloc] initWithTitle:#"Message"
message:messageString
delegate:self
cancelButtonTitle:#"Back"
otherButtonTitles:#"Reply",#"Delete",nil];
[alert show];
[alert release];
- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex
{
if (buttonIndex == 1)
{
NSLog(#"Reply");
UIAlertView *myalert = [[UIAlertView alloc] initWithTitle:#"Button Clicked" message:#"U clicked Reply " delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
[myalert show];
[myalert release];
}
if (buttonIndex == 2)
{
NSLog(#"Delete");
UIAlertView *myalert = [[UIAlertView alloc] initWithTitle:#"Button Clicked" message:#"U clicked Delete " delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
[myalert show];
[myalert release];
}
}
