問(wèn)題：自定義的進(jìn)度條CustomProgressView在TaskSubmitViewController上滑動(dòng)時(shí)發(fā)生卡頓，原因是在TaskSubmitViewController中水平滑動(dòng)進(jìn)度條的時(shí)候，可能會(huì)上下滾動(dòng)該控制器上的tableView猴蹂，所以使進(jìn)度條產(chǎn)生卡頓丑念。
解決辦法：在自定義的進(jìn)度條CustomProgressView中定義一個(gè)全局變量parentView,在TaskSubmitViewController中把全局變量myTableView賦給parentView器虾，然后在CustomProgressView中對(duì)parentView進(jìn)行控制,當(dāng)進(jìn)度條滑動(dòng)時(shí)画畅，禁止myTableView滾動(dòng)蝙泼；當(dāng)當(dāng)進(jìn)度條滑動(dòng)時(shí)谣辞，允許myTableView滾動(dòng)迫摔。
