1.WKWebView 圖片自適應(yīng)
NSString *js=@"var script = document.createElement('script');"
"script.type = 'text/javascript';"
"script.text = \"function ResizeImages() { "
"var myimg,oldwidth;"
"var maxwidth = %f;"
"for(i=0;i"
"myimg = document.images[i];"
"if(myimg.width > maxwidth){"
"oldwidth = myimg.width;"
"myimg.width = %f;"
"}"
"}"
"}\";"
"document.getElementsByTagName('head')[0].appendChild(script);";
js = [NSString stringWithFormat:js,[UIScreen mainScreen].bounds.size.width,[UIScreen mainScreen].bounds.size.width-15];
js = [NSString stringWithFormat:@"%@%@",js,@""];
WKUserScript *script = [[WKUserScript alloc] initWithSource:js injectionTime:WKUserScriptInjectionTimeAtDocumentEnd forMainFrameOnly:NO];
2 .禁止頁面縮放
1.網(wǎng)上查了下資料很多都是通過js user-scalable=no 來實(shí)現(xiàn)的 這樣也可以不過圖片大小在個(gè)別網(wǎng)頁就不自適應(yīng)了，也不知道 怎么與上面的圖片自適應(yīng)代碼組合成一段js 于是就放棄了冻河。愁茁、
NSString *injectionJSString = @"var script = document.createElement('meta');"
"script.name = 'viewport';"
"script.content=\"width=device-width, user-scalable=no\";"
"document.getElementsByTagName('head')[0].appendChild(script);";
- 再次嘗試使用 .wkWebView.scrollView代理方法來關(guān)閉縮放雏门，結(jié)果成關(guān)閉縮放了谴咸，但是圖片又不自適應(yīng)了净刮，靈機(jī)一動(dòng)直接把交互性給關(guān)了了谓晌，然后就好了具温。蚕涤。。就只設(shè)置了 1的圖片自適應(yīng)铣猩。另外吧wkWebView的交互給關(guān)閉了揖铜。
self.wkWebView.userInteractionEnabled = NO;
全部代碼
