+
+# API
+
+## switchLogLevel
+
+#### switchLogLevel(level, callback)
+
+* **@level**, log level: off|error|warning|info|debug
+* **@callback**, Callback after successfully switched level.
+
+# Usage

 * On Android, Weex only supports `overflow:hidden`.
-* On iOS, before version 0.24, Weex behaves the same as browser, so overflow is visible by default. From 0.25, overflow on iOS is hidden by default. And `overflow` is ignored on iOS. You should use 'ios-overflow' to set overflow value on iOS. Please refer to this [Demo](http://editor.weex.io/vue/13268ebfd31d8a3ef28bb6d88fa461d3)
