使用viewDidLoad时无限循环？

Question

我正在从viewDidLoad初始化一个自定义对象并从该对象调用addSubview，因此每次更新时，都会再次调用viewDidLoad。我只是不知道如何修复它，我可能实现了addSubview错误。

SLDViewController.m

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.

    SLDSlide *slide1 = [[SLDSlide alloc] initWithImage:@"building-demolition4.gif" numFrames:60 frameWidth:417 totalWidth:25020 height:238];
    [slide1 display];
}

然后我从“显示”中调用它：

- (void) display {
CGImageRef imageRef = CGImageCreateWithImageInRect(self.image.CGImage, CGRectMake(0, 0, self.frameWidth, self.height));

UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake((screenWidth - _frameWidth)/2, (screenHeight - _height)/2, _frameWidth, _height)];
imageView.userInteractionEnabled = YES;
imageView.image = [UIImage imageWithCGImage:imageRef];
CGImageRelease(imageRef);

[self.view addSubview:imageView];

NSLog(@"*** Displayed ***");
}

该对象的类型为SLDViewController。

通过将所有代码从viewDidLoad从SLDViewController移动到SLDAppDelegate DidFinishLaunching来修复此问题。
