Move to another View on PickerView Selecting Row - ios

Question

I have a picker view that has values already inside, for example one of the things inside is weather, I have a button that works with the picker view so when u pick weather and push the button an alert pops up and says Welcome to X. You selected Weather than u push OK to remove the alert, I was wondering if it was possible to after you push OK it takes you to the view controller that has the weather. I have never seen this done and this is an all in one app, also there are about 6 or 7 other items on the picker so if someone could help that would be great: here is my code. By the way I am new to the site sorry if I didn't do Code Blocks.
- (void)viewDidLoad
{
NSArray *data = [[NSArray alloc] initWithObjects:#"Weather", #"Calendar", #"Facebook", #"Twitter", #"Instagram",#"Tasks" ,nil];
self.array = data;
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
}
#pragma marks Picker Data Source Methods
-(NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component {
return [_array count];
}
-(NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView {
return 1;
}
#pragma mark Picker Delegate Methods
-(NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component {
return [_array objectAtIndex:row];
}
- (IBAction)ButtonPressed:(id)sender {
NSString *select = [_array objectAtIndex:[_picker selectedRowInComponent:0]];
NSString *title = [ [NSString alloc] initWithFormat:#"You selected %#!" , select];
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title message:#"Welcome To One" delegate:nil cancelButtonTitle:#"OK" otherButtonTitles: nil];
[alert show];
}

Answer 1

You have to do like bellow need to give tag to UIAlertView otherwise it will push view on each UIAlertView click
- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent: (NSInteger)component
{
NSString *select = [_array objectAtIndex:component];
NSString *title = [ [NSString alloc] initWithFormat:#"You selected %#!" , select];
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title message:#"Welcome To One" delegate:nil cancelButtonTitle:#"OK" otherButtonTitles: nil];
alert.tag = 1001;
alert.delegate = self;
[alert show];
}
-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if (alertView.tag == 1001)
{
[self.navigationController performSegueWithIdentifier:#"Identifier" sender:nil];
}
}

- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
{
// Show alert here
[[[UIAlertView alloc]
initWithTitle:#"" message:#"Alert Message"
delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil]
show];
}
-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if (buttonIndex == 0)
{
UIStoryboard * storyboard = self.storyboard;
ViewController * detail = [storyboard instantiateViewControllerWithIdentifier: #"YourViewControlller"];
[self.navigationController pushViewController: detail animated: YES];
}
}
