黑屏更改視圖4,5

Question

我有以下代碼：

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. 
} 

而且情節提要：

我不知道什麼我做錯了，因爲當我改變觀點，PlaceViewController是一個帶有藍色狀態欄的黑屏。

任何人都可以幫到我嗎？由於

Answer 1

，如果你使用的是故事板...進入故事板編輯器，並在屬性檢查器中，設置一個標識符，讓說「PlaceMap」（圖中「AddPlayer」）

變化您的代碼：

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

與

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

您可以阿洛斯檢查，一個非常好的教程：http://www.raywenderlich.com/5138/beginning-storyboards-in-ios-5-part-1

UPD

這是導航控制器

[self presentViewController:placeview animated:YES completion:nil];

如果你想模式

...您可以使用：

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