Currently I'm using this code but it doesn't work in iOS 7. It works fine in iOS 6:
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:title message:nil delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:Nil, nil];
[alertView show];
- (void)willPresentAlertView:(UIAlertView *)alertView {
[alertView setFrame:CGRectMake(alertView.frame.origin.x, alertView.frame.origin.y, alertView.frame.size.width, 200)];
}
How can we resize in iOS 7?

I have simple method showing AlertView with textfield. Instruments showing memory leak in this. Please explain.
- (void)method {
NSString *value = [[NSUserDefaults standardUserDefaults] valueForKey:#"key"];
if (value == nil) {
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"Title" message:#"message" delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
alertView.tag = 101;
alertView.alertViewStyle = UIAlertViewStylePlainTextInput;
UITextField *txtGroup = [alertView textFieldAtIndex:0];
[txtGroup becomeFirstResponder];
[alertView show];
alertView = nil;
}
}
Please find the screenshot of Instruments:
You need to create alertView as :
static UIAlertView *alertView = nil;
if (!alertView){
alertView = [[UIAlertView alloc] initWithTitle:#"Title" message:#"message" delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
}
Hi I have used the following function to call an alert view with a specific message. The NSLogs are being printed only once but alert view is called more than once.
I am using UITabBarController for any additional info.
- (void)showUIAlertWithMessage:(NSString *)message {
NSLog(#"showUIAlertWithMessage called");
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Something went wrong!😕😕"
message:message
delegate:self
cancelButtonTitle:#"Ok"
otherButtonTitles:nil];
[alert show];
}
Fresh and green newbie here. I just started programming and already got stuck with UIAlert. I've searched on this site but there are so many postings and as I said I am kinda new to all this so I don't know what to really look for. This is what I have.
-(void)showError {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Error"
message:#"Please try again later. Have a nice day."
delegate:nil
cancelButtonTitle:#"Dismiss"
otherButtonTitles:nil];
}
Need to do
[alert show];
to present
Code should be :
-(void)showError {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Error"
message:#"Please try again later. Have a nice day."
delegate:nil
cancelButtonTitle:#"Dismiss"
otherButtonTitles:nil];
[alert show];
[alert release];
}
[alert show];
I always forget this too. Happy Coding.
-(void)showError
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Error"
message:#"Please try again later. Have a nice day."
delegate:nil
cancelButtonTitle:#"Dismiss"
otherButtonTitles:nil];
[alert show];
}
i have create two UIAlertView views in one method. Code like below
-(void) alert{
UIAlertView *alert_1 = [[UIAlertView alloc] initWithTitle:#"Message" message:#“Alert 1” delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alert_1 show];
UIAlertView *alert_2 = [[UIAlertView alloc] initWithTitle:#"Message" message:#“Alert 2” delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alert_2 show];
}
after call this method. iPhone app will appear popup for 2 times.
first appear is alert_1, disappear alert_1 and appear alert_2
after user press ok button in alert_2 thn appear alert_1
should be remove alert_1 when appear alert_2
is possible to remove previous alert view?
Send message - (void)dismissWithClickedButtonIndex:(NSInteger)buttonIndex animated:(BOOL)animated to alert1.
UIAlertView *alert_1 = [[UIAlertView alloc] initWithTitle:#"Message" message:#“Alert 1” delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alert_1 show];
[alert_1 dismissWithClickedButtonIndex:0 animated:YES];
UIAlertView *alert_2 = [[UIAlertView alloc] initWithTitle:#"Message" message:#“Alert 2” delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alert_2 show];
I am not clear about what your requirement is. But from what I understood you want alert_2 to popup first and when clicked on the "OK" button you want to dismiss that alert view and popup alert_1
- (void) alertview
{
alert_1 = [[UIAlertView alloc] initWithTitle:#"Alert 1" message:#"Message" delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil, nil];
[alert_1 setTag:1];
alert_1.delegate = self;
alert_2 = [[UIAlertView alloc] initWithTitle:#"Alert 2" message:#"Message" delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alert_2 setTag:2];
alert_2.delegate = self;
[alert_2 show];
}
- (void) alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex
{
if (alertView.tag ==2)
{
[alert_1 show];
}
}
Please note to declare your alert views in your .h file
Get UIAlertView by its tag or #Property and use this [myAlertView dismissWithClickedButtonIndex:-1 animated:YES];
I have this code:
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title message:msg delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alert show];
[alert release];
The problem is this code crash before it shows the alert, I have tested it on lower iOS and it work but on iOS 6 it crash.
I found the answer. I coded:
[alert performSelectorOnMainThread:#selector(show) withObject:nil waitUntilDone:YES];
instead of
[alert show];
it crash because the process might not be performed in the main thread.
