核心代碼
這裡的熱更新Modal框,是封裝成一個功能獨立的組件來使用的,需不需要更新以及是否為強制更新等邏輯均在組件內實現

對UpdateComp
組件中的熱更新核心代碼講解
image
這我們在UpdateComp 組件中,在 componentWillMount
的生命周期函數中,我們調用codepush提供的這兩個函數:併在syncImmediate
函數中,我們調用codepush的checkForUpdate
函數來檢查是否已有新版本,以及新版本的信息等,具體代碼實現如下:
image
註意:
codepush有兩個代理函數我們需要調用:
image
-
codePushStatusDidChange: codepush狀態的變化的鉤子函數
-
codePushDownloadDidProgress: codepush下載更新包的進度鉤子函數
當我們處理完上面的內容,codepush的基本功能我們就處理完畢了,剩下的工作就是處理一些邏輯了,包括該不該彈更新框,以及更新彈框和更新進度的處理
總結:
本篇教程主要是講解codepush中如何處理安裝包的下載進度,以及如何自定義更新彈框和下載進度條,上面的彈框功能和下載進度條功能基本都已處理完畢,可以直接複製兩個組件代碼到自己項目中,稍作修改即可使用。如果還有小伙伴對codepush詳細的接入流程不熟悉的,請點擊查看作者的CodePush熱更新詳細接入教程一文,如果還有其他的問題,也可以簡書留言或者進群提問
