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];
