我在clickedButtonAtIndex委托中调用dismissWithClickedButtonIndex，在解雇alertview后我需要调用蓝牙设备[self callDevice]。
两者都在主线程中，但[self callDevice]首先执行，然后调用dismissWithClickedButtonIndex。所以alertview需要一段时间才能辞职。
请找到以下代码，
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
[alertView dismissWithClickedButtonIndex:1 animated:NO];
[self callDevice];
}
如何首先关闭alertview，然后调用[self callDevice] API？
任何人都可以建议我解决方案吗？

实施以下- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex
方法：
UIAlertView解雇动画完成后将调用此方法。
UIAlertController已弃用。我建议改为使用SELECT DECODE(BOM.ORGANIZATION_ID,203, 'CEC', 328, '3PL', 204, 'SIM') ORGANIZATION_CODE,
BOM.ORGANIZATION_ID,
MSI.SEGMENT1 "PARENT_ITEM",
MSIC.SEGMENT1 "COMPONENT_ITEM",
SUM(NVL(MMT.TRANSACTION_QUANTITY,0)) * NVL(SUM(CIC.ITEM_COST),0) "ANNUAL_MONEY",
SUM(NVL(MMT.TRANSACTION_QUANTITY,0)) "ANNUAL_QTY_USG",
NVL(SUM(CIC.ITEM_COST),0) "AVG_COST",
SUM(NVL(MSI.POSTPROCESSING_LEAD_TIME,0) + NVL(MSI.PREPROCESSING_LEAD_TIME,0)) LEAD_TIME
FROM BOM_BILL_OF_MATERIALS BOM
LEFT JOIN MTL_SYSTEM_ITEMS MSI
ON MSI.ORGANIZATION_ID = BOM.ORGANIZATION_ID
AND MSI.INVENTORY_ITEM_ID = BOM.ASSEMBLY_ITEM_ID

使用UIAlertView委托方法didDismissWithButtonIndex，该方法将在UIAlertView被解雇后调用。
使用didDismissWithButtonIndex，如下所示：
- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex{
if(buttonIndex==1){
//UIAlertView is dismissed by clicking button at index 1, now call your method
[self callDevice];
}
}
注意： UIAlertView已弃用，而是使用UIAlertController。
