##iOS Swift 中用JS改变UIWebView中fontSize后 UIWebView的scrollView.contenSize.height 或 webView.sizeThatFits(CGSizeZero).height都不会改变
this is my code :
func webViewDidFinishLoad(webView: UIWebView) {
//height_origin
self.webView.stringByEvaluatingJavaScriptFromString("document.getElementsByTagName('body')[0].style.webkitTextSizeAdjust= '140%'")
//height_change
//let height = self.webView.scrollView.contentSize.height //height不变
let height = self.webView.sizeThatFits(CGSizeZero).height //height不变
if self.height != height {
self.height = height
self.delegate?.webViewLoadSuccess(height)
}
self.webView.snp_updateConstraints { (make) in
make.height.equalTo(self.height)
}
}
