iphone - xcode 4,5中的黑屏更改视图

Question

我有以下代码：

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.
}

还有故事板：

我不知道我做错了什么，因为当我更改视图时， PlaceViewController 是一个带有蓝色状态栏的黑屏。

任何人都可以帮助我吗？谢谢

如果您正在使用情节提要...进入情节提要编辑器并在属性检查器中，设置一个标识符，让我们说“PlaceMap”（在图片“AddPlayer”中）

更改您的代码：

- (IBAction)passPlace:(id)sender{
    self.placeview = [[[PlaceViewController alloc] initWithNibName:nil bundle:nil] autorelease];
    [self presentViewController:placeview animated:YES completion:nil];
}

和

- (IBAction)passPlace:(id)sender{
PlaceViewController *newView = [self.storyboard instantiateViewControllerWithIdentifier:@"PlaceMap"];
[self.navigationController pushViewController:newView animated:YES];
}

您可以查看 alos，一个非常好的教程：http ://www.raywenderlich.com/5138/beginning-storyboards-in-ios-5-part-1

UPD

那是导航控制器

[自我presentViewController：placeview动画：是完成：无]；

如果你想要模态......你可以使用：

newView.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
//deprecated 6.0
//   [self presentModalViewController:newView animated:YES];
//from 5.0
[self presentViewController:newView animated:YES completion:NULL];
