NSString*injectionJSString =@"var script = document.createElement('meta');"

"script.name = 'viewport';"

"script.content=\"user-scalable=no\";"

"document.getElementsByTagName('head')[0].appendChild(script);initial-scale=1.0,maximum-scale=1.0, minimum-scale=1.0, user-scalable=no";

[webViewstringByEvaluatingJavaScriptFromString:injectionJSString];

由于我設(shè)置的表頭和H5的頁面尺寸有沖突，這里只用了user-scalable=no；

2 禁止webview跳動 可以直接在AppDelegate 里面寫 ?iOS 11的問題

? ? if(@available(iOS11.0, *)) {

?? ? ? self.dataWeb.scrollView.contentInsetAdjustmentBehavior = UIScrollViewContentInsetAdjustmentNever;

? ? ? ??[UIScrollView appearance].contentInset = UIEdgeInsetsMake(0,0, 0, 0);

? ? ? ? ?[UIScrollView appearance].scrollIndicatorInsets = self.dataWeb.scrollView.contentInset;

? ? }else{

? ? ? ? ? ? [self

?? ? ? ? ? ? setAutomaticallyAdjustsScrollViewInsets:NO];

? ? }

3 webview 和js交互 ，監(jiān)聽觸發(fā)

WKWebViewConfiguration *config = [[WKWebViewConfiguration alloc] init];

//userContenController 不能用匿名對象

userContenController = [[WKUserContentController alloc] init];

//WKUserContentController *userConteent = [[WKUserContentController alloc] init];

[userContenController addScriptMessageHandler:self name:@"NativeMethod"];

//userContenController addScriptMessageHandler:self name:@""

config.userContentController = userContenController;

//該方法可以監(jiān)聽觸發(fā)，在這里面搞事情

- (void)userContentController:(WKUserContentController*)userContentController didReceiveScriptMessage:(WKScriptMessage*)message{

NSString*messageName = message.name;

NSLog(@"%@",message);

}

4 iOS如何獲取和修改UserAgent

NSString*customUserAgent =@"ios_csf";

[[NSUserDefaults standardUserDefaults] registerDefaults:@{@"UserAgent":customUserAgent}];
