Why is this UIAlertView's Position not changing? - ios

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Blah"
message:nil
delegate:nil
cancelButtonTitle:#"Cancel"
otherButtonTitles:#"Enter", nil];
alert.alertViewStyle = UIAlertViewStyleSecureTextInput;
[alert textFieldAtIndex:0].delegate = self;
alert.delegate = self;
[alert show];
alert.frame = CGRectMake(0,0,200,100);
I've tried adding an AffineTransform as well. But it just doesn't change. Can someone help me out here?

Turns out this is just Apple trying to get everyone to move to UIAlertControllers. UIAlertController moves automatically. So that would be my suggestion to anyone here.

iOS ARC UIAlertView leaking memory

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];
}

UIAlert not showing

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];
}

is possible to remove previous alert view?

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];

Can we programmatically insert text in UIAlertView's textfield, iOS7

Can we programmatically insert text in UIAlertView's textfield, iOS7
Created UIAlertView with textinput in IOS7.
Can anyone help me with "inserting text programatically in textfield"?
Hopefully this will give answer for your question.
UIAlertView *alertView = [[UIAlertView alloc] init];
alertView.delegate = self;
alertView.title = #"Enter Info";
alertView.alertViewStyle = UIAlertViewStylePlainTextInput;
[alertView addButtonWithTitle:#"Cancel"];
[alertView addButtonWithTitle:#"OK"];
[alertView textFieldAtIndex:0].text = #"My Text";
[alertView show];
You can achieve this by using this code
UIAlertView *alert=[[UIAlertView alloc]initWithTitle:#"" message:#"whatever you like" delegate:self cancelButtonTitle:#"Ok" otherButtonTitles:#"Cancel", nil];
alert.alertViewStyle=UIAlertViewStylePlainTextInput;
[alert textFieldAtIndex:0].text=#"Hello";
[alert show];
and result will be like this:
Please try to use like this..
UIAlertView* av = [[UIAlertView alloc] init];
[av setDelegate:self];
[av setTitle:#"Hi"];
[av setMessage:nil];
[av addButtonWithTitle:#"Cancel"];
[av addButtonWithTitle:#"OK"];
av.alertViewStyle = UIAlertViewStylePlainTextInput;
[av textFieldAtIndex:0].text = #"Text";
You can use text property to set text inside textfield.
textFiled.text = #"YOUR TEXT";

Checking to see if textfields are filled out

In my Calorie Tracker App, I have two textfields. One is for the name of the food, and the other is for the amount of calories.To check and see if they are filled I wrote the following code:
if([foodString isEqual: #" "])
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Warning!" message:#"You have not entered the name of the meal!" delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil, nil];
[alert show];
}
else if([self.amountText isEqual: #" "])
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Warning!" message:#"You have not enteted the amount of calories!" delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil, nil];
[alert show];
}
else if([self.amountText isEqual:#" "] && [foodString isEqual:#" "])
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Warning!" message:#"You haven't entered anything!" delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil, nil];
[alert show];
}
So for the one where the amountText textfield isn't filled out, but the nameOfFood is filled out, there is an alert. For the rest however, there is no alert. If anyone could provide the proper syntax for checking to see if my textfields are being filled out properly, it would be much appreciated.
Remember, my first textfield is a string value, and the other is an integer value.
Thanks in advance.
