Question

我在这里做了一些AR工作，现在最大的问题之一就是我的一个UIView不响应我对它做的任何帧设置。

代码与此非常相似。我已经做了一些重大改动以纳入我的项目：

nurse.site11.com/JaredCrawford-iWVU-632a9a0/Libraries/ARKit/AugmentedRealityController.m

“displayView”用作自定义UIView，传递给UIImagePickerController的setCameraOverlayView：方法。

现在在AugmentedRealityController.m文件的initWithViewController方法中，我尝试设置displayView = [[UIView alloc] initWithFrame：CGRectMakeFrame（0,0,480,320）];

问题是，即使我将其设置为displayView = [[UIView alloc] initWithFrame：CGRectMakeFrame（0,0,100,100）];视图仍然是全屏320 x 480但仅在第一次出现增强现实视图时。 AR视图出现的后续时间，代码可以正常工作。

我不确定到底发生了什么以及为什么设置displayView的框架根本不会影响视图第一次显示它。

我希望其他人之前遇到过这个问题并且可能已经解决了。

这是我的代码：

- (id)initWithViewController:(UIViewController *)vc
{
    coordinates     = [[NSMutableArray alloc] init];
    coordinateViews = [[NSMutableArray alloc] init];
    latestHeading   = -1.0f;
    debugView       = nil;

    [self setRootViewController: vc];

    [self setDebugMode:NO];
    [self setMaximumScaleDistance: 0.0];
    [self setMinimumScaleFactor: 1.0];
    [self setScaleViewsBasedOnDistance: YES];
    [self setRotateViewsBasedOnPerspective: YES];
    [self setMaximumRotationAngle: M_PI / 6.0];

    //CGRect screenRect = [[UIScreen mainScreen] bounds];

    NSLog(@"inside initWithViewController");    

    UIDeviceOrientation orientation = [[UIDevice currentDevice] orientation];

    if(orientation == UIDeviceOrientationPortrait)
    {
        NSLog(@"Orientation portrait");
    }
    else if(orientation == UIDeviceOrientationLandscapeRight)
    {
        NSLog(@"orientation right");
        [[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeLeft];
        [self setCurrentOrientation:UIDeviceOrientationLandscapeRight];
    }
    else if(orientation == UIDeviceOrientationPortraitUpsideDown)
    {
        NSLog(@"orientation upsidedown");             
    }
    else if(orientation == UIDeviceOrientationLandscapeLeft){
        NSLog(@"orientation left");
        [[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeRight];
        [self setCurrentOrientation:UIDeviceOrientationLandscapeLeft];
    }

    //[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeLeft];


    //NSLog(@"In AR view, device orientation = %@", [[UIDevice currentDevice] orientation]);

    //[self setDisplayView: [[UIView alloc] initWithFrame: screenRect]];
    //[self setCurrentOrientation:UIDeviceOrientationLandscapeRight];

    displayView = [[UIView alloc] initWithFrame:CGRectMake(-80, 80, 480, 320)]; 

    [displayView setBackgroundColor:[UIColor colorWithRed:0.0 green:0.0 blue:1.0 alpha:0.5]];

    NSLog(@"displayView x = %f", displayView.frame.origin.x);
    NSLog(@"displayView y = %f", displayView.frame.origin.y);
    NSLog(@"displayView width = %f", displayView.frame.size.width);
    NSLog(@"displayView height = %f", displayView.frame.size.height);

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

    [[self rootViewController] setView:displayView];
    //[[self rootViewController] setView:[[UIView alloc] initWithFrame:CGRectMake(0, 0, 480, 320)]];

    //[[rootViewController view] setBackgroundColor:[UIColor blueColor]];

    CLLocation *newCenter = [[CLLocation alloc] initWithLatitude:37.41711 longitude:-122.02528];
    [self setCenterLocation: newCenter];
    [newCenter release];

    [self startListening];

    [self deviceOrientationUpdate];

    startLocation = nil;
    i = 0;
    objImageView = [[UIImageView alloc] initWithFrame:CGRectMake(0,0,320,480)];
    //[objImageView setBackgroundColor:[UIColor blueColor]];

    blnHasRotated = NO;

    return self;
}
