iOS development _uiwebview loading local HTML

This problem is encountered in the project: WebView load the local HTML Uiscrollview,webview, and then you need to calculate the webview height.

The steps are as follows:

1. First create the WebView. Note that the height must be less than the height of the HTML you want to load, preferably set a minimum value, such as 1, and set scalespagetofit = yes to make it adaptive height;

Self.bottomwebview = [[UIWebView alloc]initwithframe:cgrectmake (0, Cgrectgetmaxy (self.middleView3.frame) + Ksectioninterval, Kscreenwidth,)];    Self.bottomWebView.layer.borderColor = Self.topView.layer.borderColor;    Self.bottomWebView.layer.borderWidth = Self.topView.layer.borderWidth;    Self.bottomWebView.scalesPageToFit = YES;

2. The second is displayed in the controller. Set up the agent, load H5

Self.recordScrollView.bottomWebView.delegate = self;    [Self loadH5WithId:self.check.checkId];    [Self.view AddSubview:self.recordScrollView];

3. Load h5

NSString *path = [[NSBundle mainbundle] pathforresource:[nsstring stringwithformat:@ "cj%d.htm", (int) CheckId + 1] OfType : nil];    NSString *htmlstring = [NSString stringwithcontentsoffile:path encoding:nsutf8stringencoding Error:nil];    Nsurl *baseurl = [Nsurl Fileurlwithpath:path];    [Self.recordScrollView.bottomWebView loadhtmlstring:htmlstring Baseurl:baseurl];

4. Calculate Height in Agent method

-(void) Webviewdidfinishload: (UIWebView *) webview{        float webviewheight = [[WebView Stringbyevaluatingjavascriptfromstring: @ "Document.body.scrollHeight"] floatvalue];    Webview.frame = CGRectMake (Cgrectgetminx (Webview.frame), Cgrectgetminy (Webview.frame), CGRectGetWidth ( Webview.frame), webviewheight);    webView.scrollView.scrollEnabled = NO;        float heightsum = Cgrectgetminy (webview.frame) + webviewheight + 15;//15 increment    self.recordScrollView.contentSize = Cgsizemake (Kscreenwidth, heightsum);    }

This allows you to adapt to the height of your own.
