See Effect Chart:

(Editable text + picture Some app needs to edit article function with this can be achieved in general, pictures and text have been acquired to the server after the corresponding upload, before no Yytextview also achieved this function, the effect is relatively poor, with this realization, quite perfect, Must give the Yytext author a compliment.
