Question

崩溃：

- [UIImageView setParentViewController：]：无法识别的选择器发送到实例0x58701e * 因未捕获的execption'NSInvalidArgumentExecption'而终止应用程序，原因：' - [UIImageView setParentViewController：]：无法识别的选择器发送到实例0x58701e0'

当我尝试推送没有IB的自定义UIViewController时会发生这种情况。

当我使用IB执行此操作时，它可以正常工作，但这并不是我需要的。

为我的代表召集的是什么

-(void)switchToTrailerOne 
{
CGsize screenSize = [UIScreen mainScreen].bounds.size;
CGRect screenBounds = CGRectMake(0, 0, ScreenSize.width, screenSize.height);
TrailersViewController *trailersController = [[TrailersViewController alloc] initWithFrame:screenBounds];

[self.navController pushViewController:trailersController animated:NO]; (Crashes on this line)

[trailersController gotoFirstTrailer];
}

问我任何其他代码，因为我几乎从不远离comp一次超过一小时。

编辑：你感兴趣的任何特定部分的文件有点长吗？我会发布一些我认为可能会出现的情况......

-(void)loadView{

    CGSize screenSize = [UIScreen mainScreen].bounds.size;
    CGRect screenBounds = CGRectMake(0, 0, screenSize.width, screenSize.height);

    //Copy the Node Collection to the Receiver Array
    nodeArray                = nodeCollection.createNodeList;

    //Done With Node Collection Release it
    [nodeCollection release];

    recognizerRight.direction = UISwipeGestureRecognizerDirectionRight;
    [myTrailersView addGestureRecognizer:recognizerRight];
    [recognizerRight release];
}

- (id)initWithFrame:(CGRect)frame {
    self = [super.view initWithFrame:frame];

    return self;

看起来好像是在尝试推送自定义UIView而不是自定义UIViewController。检查TrailersViewController类层次结构。

iOS - NavController＆amp;自定义视图
