问题 looking for mem leaks elsewhere in our system, I created a 20 MB web page with a meta refresh tag. the idea was to move a lot data through our datapath code to confirm mem stability. <html> <meta http-equiv="refresh" content="1"> <body> <div style="border: 1px solid red"> Content loading </div><!-- 20mb worth of comments --> </body> </html> what I found was the uiwebview displaying that meta refresh page leaks memory very, very fast. the app memory hits 300mb in about 2 minutes and gets shot

由 二次信任 提交于 2019-12-17 08:09:55
