objective-c - 以编程方式将 UIWebView 添加到 UIImageView

Question

我希望能够向 UIImage 添加缩放功能，并且相信最好的方法是嵌入到 UIWebview 中。有人能帮我实现这个目标吗？

- (void)viewDidLoad
{
[super viewDidLoad];

// image
self.imageView = [[UIImageView alloc] initWithFrame:CGRectMake(10, 70, IMGSIZE.width, IMGSIZE.height)];
[self.imageView setClipsToBounds:YES];
self.imageView.layer.borderColor = kITBarTint.CGColor;
self.imageView.layer.borderWidth = 1.0;
self.imageView.layer.cornerRadius = 15.0;
self.imageView.layer.shadowColor = [UIColor blackColor].CGColor;
self.imageView.layer.shadowOffset = CGSizeMake(5, 5);
self.imageView.layer.shadowRadius = 10;

[self.controller.view addSubview:self.imageView];

// activity indicator
CGRect frame = CGRectMake(roundf(IMGSIZE.width / 2) + self.imageView.frame.origin.x, roundf(IMGSIZE.height /2) + self.imageView.frame.origin.y, 0, 0);
_activityIndicator = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];
[_activityIndicator setFrame:frame];
[_activityIndicator startAnimating];
[self.controller.view addSubview:_activityIndicator];


}

尝试将此添加到您的 viewDidLoad 方法中，

scrollView.minimumZoomScale = 0.4;
scrollView.maximumZoomScale = 4.0;
scrollView.delegate = self;
[scrollView setZoomScale:scroll.minimumZoomScale];

希望这对您有所帮助!

并尝试使用 UIScrollView
