一.position:fixed/absolute出现随屏幕滚动情况
在position:fixed/absolute内加入
-webkit-transform: translateZ(0);
假如有遮罩情况则在内容区域，加入 ：
margin-bottom:20px;//margin-top:20px;
抖动情况，加入 ：
overflow-y: auto;
二.下载iOS离线sdk后签名问题
报错：
HBuilder has conflicting provisioning settings.
HBuilder is automatically signed for development, but a conflicting code signing identity Apple Distribution has been manually specified. Set the code signing identity value to "Apple Development" in the build settings editor, or switch to manual signing in the Signing & Capabilities editor.
解决方法：
Build Settings 搜索 provisioning 删除 PROVISIONING_PROFILE
Build Settings 搜索

图中改为“Apple Development”
三.上传App Store问题
could not find the service with interface (com.apple.transporter.osgi.TransporterService)

解决方法：
删除 /Users/XXX/Library/Caches/com.apple.amp.itmstransporter/ 文件夹
命令行输入

下载完了后重启Xcode，搞定！
