With regard to multi-label view

Interface as shown



When I click on the second tab single time, jumped out to a direct interface directly transferred to the main interface of the simulator, and how is it?



. H code that tab: The following

 
# Import  


@ Interface SingleComponentPickerViewController: UIViewController 
 
{
IBOutlet UIPickerView * singlepicker; 
NSArray * pickerdate; 


} 
@ Property (nonatomic, retain) UIPickerView * singlepicker; 
@ Property (nonatomic, retain) NSArray * pickerdate; 

- (IBAction) buttonpressed; 

@ End 

Tab. M code

 
# Import "SingleComponentPickerViewController.h" 


@ Implementation SingleComponentPickerViewController 
@ Synthesize singlepicker; 
@ Synthesize pickerdate; 

/ / The designated initializer. Override if you create the controller programmatically and want to perform customization that is not appropriate for viewDidLoad. 
/ *

/ / Custom initialization.

return self; 
}

NSString * select = [pickerdate objectAtIndex: row]; 
NSString * title = [[NSString alloc] initWithFormat: @ "you select% @", select]; 
UIAlertView * alert = [[UIAlertView alloc] initWithTitle: title 
message: @ "thanks you for choosing" 
delegate: nil 
cancelButtonTitle: @ "you are welcome" 
otherButtonTitles: nil]; 
[Alert show]; 
[Alert release]; 
[Title release]; 
} 

/ / Implement viewDidLoad to do additional setup after loading the view, typically from a nib.

[Array release]; 
[Super viewDidLoad]; 
}

- (BOOL) shouldAutorotateToInterfaceOrientation: (UIInterfaceOrientation) interfaceOrientation {
/ / Return YES for supported orientations. 
return (interfaceOrientation == UIInterfaceOrientationPortrait); 
} 
* / 

- (Void) didReceiveMemoryWarning {
/ / Releases the view if it doesn't have a superview. 
[Super didReceiveMemoryWarning]; 

/ / Release any cached data, images, etc. That aren't in use.

[Super viewDidUnload]; 
/ / Release any retained subviews of the main view. 
/ / E.g. self.myOutlet = nil; 
} 


- (Void) dealloc {
[Singlepicker release]; 
[Pickerdate release]; 
[Super dealloc]; 
}
