Opening a new view controller after alert

enter code hereI am having trouble with going back to the previous view controller when alert is presented.
What I am trying to do is have the user enter in data, then an alert appear saying it was successful, then return to the previous view controller.
I currently have no code doing so and am seeking assistance with what I should put in.
- (IBAction)saveLabel:(id)sender
{
NSArray *data = [[NSUserDefaults standardUserDefaults] objectForKey:#"DATA"];
NSMutableArray *currentDataArray;
if (data == nil)
{
currentDataArray = [[NSMutableArray alloc]init];
}
else
{
currentDataArray = [[NSMutableArray alloc]initWithArray:data];
}
[currentDataArray addObject:self.textField.text];
[[NSUserDefaults standardUserDefaults] setObject:currentDataArray forKey:#"DATA"];
}
- (IBAction)enterButtonPressed:(id)sender
{
NSLog(#"enterButtonPressed");
UIAlertView *enterAlert = [[UIAlertView alloc]initWithTitle:nil message:#"Entry was recorded" delegate:nil cancelButtonTitle:#"Okay" otherButtonTitles:nil, nil];
[enterAlert show];
}
//If u r using dismissing
[self dismissViewControllerAnimated:YES completion:^{
UIAlertView *enterAlert = [[UIAlertView alloc]initWithTitle:nil message:#"Entry was recorded" delegate:nil cancelButtonTitle:#"Okay" otherButtonTitles:nil, nil];
[enterAlert show];
}];
//if u r using navigation ,popViewController
[CATransaction begin];
[CATransaction setCompletionBlock:^{
// handle completion here
UIAlertView *enterAlert = [[UIAlertView alloc]initWithTitle:nil message:#"Entry was recorded" delegate:nil cancelButtonTitle:#"Okay" otherButtonTitles:nil, nil];
[enterAlert show];
}];
[self.navigationController popViewControllerAnimated:YES];
[CATransaction commit];
Set Delegate self of your UIAlertView
UIAlertView *enterAlert = [[UIAlertView alloc]initWithTitle:nil message:#"Entry was recorded" delegate:self cancelButtonTitle:#"Okay" otherButtonTitles:nil, nil];
[enterAlert show];
Use Delegate Method of UIAlertviewController.
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if(buttonIndex==0){
// Do your Stuff Here....
[self.navigationController popViewControllerAnimated:TRUE];
}
}
Add the following UIAlertViewDelegate method to your implementation file:
- (void)alertView:(UIAlertView *)alertView
didDismissWithButtonIndex:(NSInteger)buttonIndex {
// If you are presenting this view controller
[self dismissViewControllerAnimated:YES completion:nil];
// If you are pushing this view controller
[self.navigationController popViewControllerAnimated:YES];
}
Also remember to set your UIAlertView delegate to your view controller, change to the following code:
UIAlertView *enterAlert = [[UIAlertView alloc]initWithTitle:nil message:#"Entry was recorded" delegate:self cancelButtonTitle:#"Okay" otherButtonTitles:nil, nil];
UIAlertView *enterAlert = [[UIAlertView alloc]initWithTitle:nil message:#"Entry was recorded" delegate:nil cancelButtonTitle:#"Okay" otherButtonTitles:nil, nil];
enterAlert.tag=100;
[enterAlert show];
}
-(void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex {
if (alertView.tag == 100) {
if (buttonIndex == 0) {
// Do something when ok pressed
// If you are presenting this view controller
[self dismissViewControllerAnimated:YES completion:nil];
// If you are pushing this view controller
[self.navigationController popViewControllerAnimated:YES];
} else {
// Do something for other alertviewButton}
else{// Do something with responses from other alertViews by giving tags
}

Change iOS tab view from alert

I have a tabbed application with 2 tab views. I want to change the view from the second tab to the first when the user presses "OK" on an alert view.
The following code snippet works when I use it on an -IBAction button pressed, but it doesn't do anything when I use it inside the alert code:
self.tabBarController.selectedViewController = [self.tabBarController.viewControllers objectAtIndex:0];
Why does it not work when used as below, in my SeondViewController.m in my
- (void)viewDidLoad {
[super viewDidLoad];?
UIAlertView *alert =[[UIAlertView alloc]
initWithTitle:#"Camera and Target coincident"
message:msg
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alert show];
self.tabBarController.selectedViewController = [self.tabBarController.viewControllers objectAtIndex:0];
I'm just learning this, so anything you can offer would be helpful.
When I use the following code:
if ([ theProjection Trans_Initialise] == 1) {
NSString * msg = nil;
UIAlertView *alertView =[[UIAlertView alloc] initWithTitle:#"Camera and Target coincident" message:msg delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alertView show];
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
if ([[alertView buttonTitleAtIndex:buttonIndex] isEqualToString:#"OK"]) {
self.tabBarController.selectedIndex = 0;
}
}
I get the error message on -(void) alertView "Invalid argument type void to unary expression" Am I doing something grammatical, or is it (quite possibly) something I just didn't understand?
First of all, you need a delegate call back from the alert view informing you about the button that was clicked.
Your alert view should be created like this :
UIAlertView *alert =[[UIAlertView alloc] initWithTitle:#"Camera and Target coincident" message:msg delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
Then in your m file implement the function :
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
if ([[alertView buttonTitleAtIndex:buttonIndex] isEqualToString:#"OK"]) {
self.tabBarController.selectedIndex = 0;
}
}

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];

Alertview with integer

Hello to everyone i would like to place my thinking about an alertview. I am thinking to create an Uialertview which will prompt the user to input two integers. Then i would like to retrieve these two integers and put the one on a timer and the second in an sql statement. So if anyone can help on how to implement that i would apreciate it. Thank you all.
Here is my code until now
UIAlertView * alertView = [[UIAlertView alloc] initWithTitle:#"info" message:#"Set time For The Game." delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:#"cancel", nil];
alertView.alertViewStyle=UIAlertViewStylePlainTextInput;
NSLog(#"Entered: %#", [[alertView textFieldAtIndex:0] text]);
[alertView show];
You need to use delegate methods of UIAlterView.
First of all make "self a delegate" instead of nil.
UIAlertView * alertView = [[UIAlertView alloc] initWithTitle:#"info" message:#"Set time For The Game." delegate:self cancelButtonTitle:#"OK" otherButtonTitles:#"cancel", nil];
Than add this function to your class:
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
UITextField *field = [alertView textFieldAtIndex:0];
NSLog(#"%#", field.text);
}
To be 100% correct add also in your header class information that you implement this protocol .
// Try this
UIAlertView * alertView = [[UIAlertView alloc] initWithTitle:#"info" message:#"Set time For The Game." delegate:self cancelButtonTitle:#"OK" otherButtonTitles:#"cancel", nil];
alertView.alertViewStyle=UIAlertViewStylePlainTextInput;
[alertView textFieldAtIndex:0].delegate = self;
[alertView show];
-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
NSLog(#"Entered: %#", [[alertView textFieldAtIndex:0]text]);
}

display alertview while deleting data in plist

I want to delete data in UITableView using plist and i want to put alertview when delete button is pressed. I want to mention that i have used edit button to delete the data from tableview. code of edit button is as follows: for your information.
self.navigationItem.leftBarButtonItem=self.editButtonItem;
Plz help me solve this problem.
thanx in advance.
In your function write :
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle: #"" message: #"" delegate: self cancelButtonTitle: #"OK" otherButtonTitles: nil];
alertView.tag = 1;
[alertView show];
[alertView release];
On alert "OK" button pressed
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if(buttonIndex==0)
{
if (alertView.tag == 1)
{
//Do your code
}
}
}
Hope it helps...
on you button action write:-
-(IBAction)btnPressed
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"" message:#"" delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil,nil];
[alert show];
[alert release];
}
- (void)alertView:(UIAlertView *)alert didDismissWithButtonIndex:(NSInteger)buttonIndex
{
}
