720 Collapse
#import " HelloPanoramaViewController.h" #导入 “HelloPanoramaViewController.h”@implementation HelloPanoramaViewController @执行HelloPanoramaViewController@synthesize plView; @综合plView; // Implement viewDidLoad to do additional setup after loading the view, typically from a nib. / /执行viewDidLoad做额外的设置视图加载后,笔尖通常是从。 - ( void )viewDidLoad - (  )viewDidLoad { { [super viewDidLoad]; [超级viewDidLoad]; // Example with Spherical type / /球型的示例plView.isDeviceOrientationEnabled = YES; plView.isDeviceOrientationEnabled =是;plView.isAccelerometerEnabled = YES; plView.isAccelerometerEnabled =是;plView.isScrollingEnabled = YES; plView.isScrollingEnabled =是;plView.isInertiaEnabled = YES; plView.isInertiaEnabled =是; plView.type = PLViewTypeSpherical; plView.type = PLViewTypeSpherical; [plView addTextureAndRelease:[PLTexture textureWithPath:[[NSBundle mainBundle] pathForResource: @" pano" ofType: @" jpg" ]]]; [plView addTextureAndRelease:[PLTexture textureWithPath:[[NSBundle mainBundle] pathForResource:@“全景”ofType:@“jpg”的 ]]]; } } - ( void )dealloc - ( 无效 )的dealloc { { [plView release]; [plView新闻稿]; [super dealloc]; [超级的dealloc]; }} @end @结束

6. 6。 plView variable pointing to the view in the resource file "MainWindow.xib" plView变量指向资源文件中的“MainWindow.xib文件”的观点

7. 7。 Add a resource image as "pano.jpg" this image must be Spherical for this example.新增为“pano.jpg”这个图片必须为这个例子球形资源的形象。
