Question

我可以通过SSH将应用程序部署到越狱设备。我用ldid签名，但是当我尝试运行它时，我得到：

dyld: Symbol not found: _OBJC_CLASS_$_PLCameraController
Referenced from: /private/var/stash/Applications.pwn/iPhoneCam.app/iPhoneCam
Expected in: flat namespace

Trace/BPT trap

错误。我运行的代码是;

- (void)applicationDidFinishLaunching:(UIApplication *)application {    
// Override point for customization after app launch    
[window addSubview:viewController.view];
[window makeKeyAndVisible];

[[UIApplication sharedApplication] setStatusBarHidden:YES animated:NO];

// Get the view for preview and start preview 
PLCameraController *cam = [PLCameraController sharedInstance]; 
UIView *view = [cam previewView]; 
[cam startPreview]; 

// Add the preview view to window 
[window addSubview:view]; 

// Override point for customization after app launch 
[window makeKeyAndVisible]; 
}

如果您只需要“全屏”相机视图，则可以将UIImagePickerController子类化为

- (void)viewDidLoad {
   [super viewDidLoad];
[self setSourceType:UIImagePickerControllerSourceTypeCamera];
[self setShowsCameraControls:FALSE];
[self.view setFrame:CGRectMake(0, 0, 320, 480)];
}

从SDK3.1开始，您可以使用cameraOverlayView属性设置自定义相机UI控件。

setFrame并没有使实际的相机视图全屏显示 - 我不相信这可能是真的 - 所以我想你也可以把它留下来。

我明白了;不知何故，我需要将对象称为：

objc_getClass("PLCameraController")

使用PLCameraView时，设备上找不到iPhone符号错误
