Obj-C，如何將iPhone模擬器轉到橫向？

Question

過去，我已經設法做到這一點，您可以打開某個視圖，然后模擬器向左轉，然后再回到縱向。

我可以使景觀成為風景，但我必須轉過頭才能看到它。

我正在嘗試Moriatry餅圖 。

這是我在viewWillAppear使用的代碼

CGRect myImageRect = CGRectMake(0.0f, 20.0f, 460.0f, 280.0f); 
BNPieChart* chart = [[BNPieChart alloc] initWithFrame:myImageRect];
[chart addSlicePortion:0.1 withName:@"Orange 10%"];
[chart addSlicePortion:0.2 withName:@"Fandango 10%"];
[chart addSlicePortion:0.1 withName:@"Blue 10%"];
[chart addSlicePortion:0.1 withName:@"Cerulean 10%"];
[chart addSlicePortion:0.3 withName:@"Green 10%"];
[chart addSlicePortion:0.1 withName:@"Yellow 10%"];
[chart addSlicePortion:0.1 withName:@"Pink 10%"];
[self.view addSubview:chart];

這些是我嘗試過的。...也許我沒有正確使用它們？

PieChartViewController *nextController = [[[PieChartViewController alloc] 
  initWithNibName:@"PieChartView" bundle:nil] autorelease];
AppDelegate *delegate = (AppDelegate *)[[UIApplication sharedApplication] 
  delegate];

CGAffineTransform newTransform = 
  CGAffineTransformMake(0.0,1.0,-1.0,0.0,0.0,0.0);         
nextController.view.transform = newTransform;
[nextController setModalTransitionStyle:UIModalTransitionStyleCrossDissolve];

[delegate.graphNavController pushViewController:nextController animated:YES];

和這個..

- (BOOL) shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)
  interfaceOrientation {
   return (interfaceOrientation == UIInterfaceOrientationLandscapeLeft ||
   interfaceOrientation == UIInterfaceOrientationLandscapeRight);
}

還有...

- (void)viewDidLoad {
[super viewDidLoad];

[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];   
[[NSNotificationCenter defaultCenter] addObserver:self
    selector:@selector(didRotate:)
    name:@"UIDeviceOrientationDidChangeNotification" 
    object:nil];    
}

- (void) didRotate:(NSNotification *)notification { 
UIDeviceOrientation orientation = [[UIDevice currentDevice] orientation];

  if (orientation == UIDeviceOrientationLandscapeLeft || 
    orientation == UIDeviceOrientationLandscapeRight) {
    return;
  }

}

Answer 1

在Simulator iOS中，轉到菜單硬件，向左旋轉（向右旋轉）！

Answer 2

如果將應用程序/視圖設置為僅在橫向模式下運行，則模擬器將自動切換為橫向模式。 （您可能還必須在plist文件中設置支持的界面方向）。

如果應用程序支持所有方向，則必須使用菜單/鍵盤命令來旋轉它。
