问题是我想在开始时看到所有适合屏幕的图像,但它显示已经缩放.有没有办法处理这个请帮忙...
The problem is I want to see all the image fit to screen at start but it is showing already zoomed. Is there a way to handle this please help ...
我有这样的代码:
[self.view addSubview:scrollView]; UIImageView *tempImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"Tree.jpg"]]; self.imageView = tempImageView; [tempImageView release]; [scrollView setContentMode:UIViewContentModeScaleAspectFit]; [imageView sizeToFit]; scrollView.backgroundColor=[UIColor blackColor]; scrollView.contentSize = imageView.frame.size; scrollView.minimumZoomScale = scrollView.frame.size.width / imageView.frame.size.width; scrollView.maximumZoomScale = 4.0; [scrollView setZoomScale:1.0]; scrollView.clipsToBounds = YES; scrollView.delegate = self; [scrollView addSubview:imageView];
推荐答案
可能你正在寻找这个,
UIImageView *tempImageView = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"Watson.jpg"]] autorelease]; tempImageView.frame = scrollView.bounds; self.imageView = tempImageView; scrollView.backgroundColor = [UIColor blackColor]; scrollView.minimumZoomScale = 1.0 ; scrollView.maximumZoomScale = imageView.image.size.width / scrollView.frame.size.width; scrollView.zoomScale = 1.0; scrollView.delegate = self; [scrollView addSubview:imageView];
