一.position:fixed/absolute出現隨屏幕滾動情況
在position:fixed/absolute內加入

-webkit-transform: translateZ(0);

假如有遮罩情況則在內容區域，加入 ：

margin-bottom:20px;//margin-top:20px;

抖動情況，加入 ：

overflow-y: auto;

二.下載iOS離線sdk后簽名問題
報錯：

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.

解決方法：
Build Settings 搜索 provisioning 刪除 PROVISIONING_PROFILE
Build Settings 搜索

圖中改為“Apple Development”

三.上傳App Store問題

could not find the service with interface (com.apple.transporter.osgi.TransporterService)

Resolver: Install error - com.fasterxml.jackson.module.jackson-module-jaxb-annotations Exception's name: java.io.IOException, Exception's message: Error accessing file:/Users/XXX/Library/Caches/com.apple.amp.itmstransporter/obr/2.1.0/com.fasterxml.jackson.module.jackson-module-jaxb-annotations-2.9.8.jar

解決方法：
刪除 /Users/XXX/Library/Caches/com.apple.amp.itmstransporter/ 文件夾
命令行輸入

/Applications/Xcode.app/Contents/SharedFrameworks/ContentDeliveryServices.framework/Versions/A/itms/bin/iTMSTransporter

下載完了后重啟Xcode，搞定！
