Block回调

情况1：界面pop后，调用上一界面的方法

#import "xxxxxx.h"  //当前页面
/*
 * 修改备注名
 */
- (void)ChangeRemark:(UIButton*)sender {
    UIStoryboard *fundSt = [UIStoryboard storyboardWithName:@"Main" bundle:GNNTBUNDLE];
    FrameWork_RemarkTableViewController *VC = [fundSt instantiateViewControllerWithIdentifier:@"FrameWork_Remark"];
    CommonContactList *list=[_dataArray objectAtIndex:sender.tag];
    VC.tag=sender.tag;
    VC.receiveAssetUserID=list.oftenUseAssetUserID;
    __weak typeof(self) weakSelf = self;
    VC.Refrish=^{
        [weakSelf.tableView headerBeginRefreshing];
    }; //哪个地方push过去的，就在哪个地方写block
    [self.navigationController pushViewController:VC animated:YES];

}

typedef void (^BlockRefrish)();
@property (nonatomic, copy) BlockRefrish Refrish;
 #improt "FrameWork_RemarkTableViewController.h"
  if (resp.result.retCode>= 0) {
                [FrameWork_CommonTool showDialogWithMessage:@"修改成功"];
                [self.navigationController popViewControllerAnimated:YES];
                self.Refrish();
            }else{
                [FrameWork_CommonTool showDialogWithMessage:resp.result.message];
            }

情况2：请求回数据，调用下拉刷新（同一界面）

-(void)viewdidload{
 self.BlockHeader=^{
         [weakSelf.tableView headerBeginRefreshing];
    };
}

-(void)sendMsg{
  if (resp.result.retCode>= 0) {
                    [FrameWork_CommonTool showDialogWithMessage:@"添加成功"];
                    self.BlockHeader();
                }else{
                    [FrameWork_CommonTool showDialogWithMessage:resp.result.message];
                }
}
