UIWebView内存占用过高、崩溃、内存溢出

项目当中模拟器上运行UIWebView读取本地杂志,没问题，真机测试经常内存溢出崩溃。

查了资料因为Html里的js 导致的内存泄漏，每次打开一个连接就会把“WebKitCacheModelPreferenceKey”设置成1。

UIWebView 增加

– (void)webViewDidFinishLoad:(UIWebView *)webView { [[NSUserDefaults standardUserDefaults] setInteger:0 forKey:@"WebKitCacheModelPreferenceKey"];}

解决问题

原因:

Your are going to have a big memory usage and leak a lot of data!But there is a hack to solve this problem: revert what is done when you open a link.In fact, the key property which leads to this leak is the WebKitCacheModelPreferenceKey application setting. And when you open a link in a UIWebView, this property is automatically set to the value "1". So, the solution is to set it back to 0 everytime you open a link. You may easily do this by adding a UIWebViewDelegate to your UIWebView :

– (void)webViewDidFinishLoad:(UIWebView *)webView { [[NSUserDefaults standardUserDefaults] setInteger:0 forKey:@"WebKitCacheModelPreferenceKey"];}

So are you going to have much less crash due to "Low Memory" 🙂

崩溃次数减少很多。
