Black screen changing views in xcode 4,5 - iphone

Question

I have the following code:
MapViewController.h
#import <UIKit/UIKit.h>
#import "PlaceViewController.h"
#interface MapViewController : UIViewController <MKMapViewDelegate> {
IBOutlet PlaceViewController *placeview;
}
- (IBAction)passPlace:(id)sender;
MapViewController.m
#synthesize placeview;
- (IBAction)passPlace:(id)sender{
self.placeview = [[[PlaceViewController alloc] initWithNibName:nil bundle:nil] autorelease];
[self presentViewController:placeview animated:YES completion:nil];
}
PlaceViewController.h
#interface PlaceViewController : UIViewController{
}
- (IBAction)back:(id)sender;
#end
PlaceViewController.m
#implementation PlaceViewController
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
NSLog(#"Change!!!!!");
[super viewDidLoad];
// Do any additional setup after loading the view.
}
And the storyboard:

I have no idea that what I'm doing wrong because when I change view, the PlaceViewController is a black screen with a blue status bar.
Anyone can help me? Thanks

Answer 1

if you are using storyboard... go into the Storyboard Editor and in the Attributes Inspector, set an Identifier, let say "PlaceMap" (in picture “AddPlayer”)
change your code:
- (IBAction)passPlace:(id)sender{
self.placeview = [[[PlaceViewController alloc] initWithNibName:nil bundle:nil] autorelease];
[self presentViewController:placeview animated:YES completion:nil];
}
with
- (IBAction)passPlace:(id)sender{
PlaceViewController *newView = [self.storyboard instantiateViewControllerWithIdentifier:#"PlaceMap"];
[self.navigationController pushViewController:newView animated:YES];
}
You can check alos, a very nice tutorial: http://www.raywenderlich.com/5138/beginning-storyboards-in-ios-5-part-1
UPD
that is for Navigation Controller
[self presentViewController:placeview animated:YES completion:nil];
if you want modal... can you use:
newView.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
//deprecated 6.0
// [self presentModalViewController:newView animated:YES];
//from 5.0
[self presentViewController:newView animated:YES completion:NULL];
