Password not A and A show alertView "Username or Password wrong"
and row:1 working same from row:0 but Username and Password must be B and B only and
go to(modal) View:B not View:A
Any suggestions?

[super viewDidLoad];
_Data = [[NSArray alloc] initWithObjects:#"Place1", #"Place2", #"Place3", #"Place4", #"Place5", #"Place6", nil];

{
return 1;
}
-(NSInteger) pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component

return [_Data count];
}
-(NSString *) pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component

Try something like this:
- (void)viewDidLoad
{
[super viewDidLoad];
NSDictionary* dict1 = [NSDictionary dictionaryWithObjectsAndKeys: #"Place1", #"place", #"TSViewController1", #"vcclass", #"User1", #"userName", #"qwerty", #"password", nil];
NSDictionary* dict2 = [NSDictionary dictionaryWithObjectsAndKeys: #"Place1", #"place", #"TSViewController1", #"vcclass", #"User2", #"userName", #"wwwrtt", #"password", nil];
_Data = [[NSArray alloc] initWithObjects: dict1, dict2, nil];
}
-(NSString *) pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component
{
return [[_Data objectAtIndex: row] objectForKey: #"place"];
}
- (IBAction)ShowID:(id)sender
{
NSInteger indexPicker = [_pickerView selectedRowInComponent: 0];
UIAlertView *alert = [[UIAlertView alloc] initWithTitle: #"Login"
message: [NSString stringWithFormat: #"Enter Username and Password for %#", [_Data objectAtIndex: indexPicker]]
delegate: self
cancelButtonTitle: #"Cancel"
otherButtonTitles: #"Login", nil];
[alert setAlertViewStyle: UIAlertViewStyleLoginAndPasswordInput];
[alert show];
}
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
NSString *title = [alertView buttonTitleAtIndex:buttonIndex];
if([title isEqualToString:#"Login"])
{
NSInteger indexPicker = [_pickerView selectedRowInComponent: 0];
NSString* username = [[_Data objectAtIndex: indexPicker] objectForKey: #"userName"];
NSString* password = [[_Data objectAtIndex: indexPicker] objectForKey: #"password"];
NSString* yourUsername = [alertView textFieldAtIndex:0].text;
NSString* yourpassword = [alertView textFieldAtIndex:1].text;
if ([username isEqualToString: yourUsername] && [yourpassword isEqualToString: password])
{
NSString* viewControllerClassName = [[_Data objectAtIndex: indexPicker] objectForKey: #"vcclass"];
Class classOfViewController = NSClassFromString(viewControllerClassName);
UIViewController* viewController = [[classOfViewController alloc] init];
[self presentModalViewController: viewController
animated: YES];
// or [self.navigationController pushViewController:viewController animated:YES];
}
}
}
In .h:
#interface ...
{
NSArray* _DataLogin;
NSArray* _Data;
UIPickerView* _pickerView;
}
Then you should create your custom view controllers. You can also use presentModalViewController instead of the pushViewController.
