YYText是強(qiáng)大的YYKit的一部分可以單獨(dú)下載

Powerful text framework for iOS to display and edit rich text. (It's a component ofYYKit)

集成的時(shí)候建議使用cocopod管理

1.里面主要兩個(gè)控件：

YYTextView 和 YYLabel

現(xiàn)在主要是YYTextview的簡(jiǎn)單使用

YYText主要是NSMutableAttributedString來(lái)處理富文本 他的內(nèi)部實(shí)現(xiàn)可以自己去深究。

簡(jiǎn)單的圖文并排，使用NSMutableAttributedString創(chuàng)建一個(gè)對(duì)象 然后 appendAttributesString來(lái)拼接文字和圖片(占位)

@end以上代碼加上注釋?xiě)?yīng)該很容易理解就不多講了 ?注意 \n 這個(gè)換行符的使用

看效果圖：

(可編輯的文本+圖片 有的app需要編輯文章功能 用這個(gè)就個(gè)可以大體實(shí)現(xiàn)了，圖片和文本都已經(jīng)獲取到了 到時(shí)后對(duì)應(yīng)傳到服務(wù)器，之前沒(méi)用YYTextview也實(shí)現(xiàn)過(guò)這種功能，效果比較差，用這個(gè)實(shí)現(xiàn)，相當(dāng)完美，必須給YYText作者點(diǎn)個(gè)贊)

創(chuàng)作挑戰(zhàn)賽新人創(chuàng)作獎(jiǎng)勵(lì)來(lái)咯，堅(jiān)持創(chuàng)作打卡瓜分現(xiàn)金大獎(jiǎng)

總結(jié)
