最近因項(xiàng)目需求,需要用到強(qiáng)制更新功能,網(wǎng)上搜了一下,挺多的,但是把網(wǎng)上的代碼拷貝以后,發(fā)現(xiàn)一個(gè)bug,就是進(jìn)app,彈出框顯示,點(diǎn)擊現(xiàn)在升級(jí),跳轉(zhuǎn)到AppStore下載里面,但是我不下載,又切回到app里面,發(fā)現(xiàn)彈出框就不跳了,其實(shí)也簡單,就是appdelegate里面有個(gè)代理方法,就是當(dāng)app從后臺(tái)切到前臺(tái)走的方法,將強(qiáng)制更新方法在這里面在調(diào)用一下就行了~~~話不多說,上代碼?。?!用的話直接粘貼復(fù)制~
