我試圖做到以下幾點:如何顯示「加載」釦子AlertView在執行REST請求
- 顯示出「正在加載」消息
一個釦子UIAlertView中執行像一個REST請求
currentPlans = [RestUtils restSynchnonousCall:url usingMethod:@"GET" withBody:nil];
駁回UIAlertView中
return currentPlans
我看了dispatch_async
模式,我也看了這個線程UIAlertView starts to show, screen dims, but it doesn't pop up until it's too late!不理解這麼多... :(
預先感謝您!
