将UIView添加到已经添加到MainView的子视图中

结构是这样的..

*)MainView

*) MainView

     1) viewLocations(UIVIEW) // this one is adding fine

            a) viewBangalore
            b) viewHyderbad

实际上，我在做一个iPad App，在其中一个UIViewController中，我使用UiTableController作为滑动视图来选择Locations.根据位置选择，需要显示UiView的.

Actually I'm doing a iPad App , in one of the UIViewController I've used a UiTableController as a sliding view to pick the Locations . According to locations pick ,need to display UiView's.

viewLocations-> CGRectMake(0,108,588,533)

viewLocations --> CGRectMake(0,108,588,533)

这里我的代码是:

 if (_detailItem) {
        Location=[_detailItem description];

        if ([Location isEqual:@"Bangalore"]) {
           self.viewLocBangalore= [[UIView alloc] initWithFrame:CGRectMake(10, 10, 500, 400)];
           // self.viewLocBangalore.frame = CGRectMake(10, 10, 500, 400);
            [self.viewLocations addSubview:self.viewLocBangalore];

          [UIView transitionFromView:self.viewLocHyderbad
                                toView:self.viewLocBangalore
                              duration:0.9
                               options:UIViewAnimationOptionTransitionFlipFromBottom

                            completion:^(BOOL finished) {
                                NSLog(@"Locations View Appeared %@", Location);
                            }];

        }

        else if ([Location isEqual:@"Hyderbad"])
        {
            self.viewLocHyderbad.frame = CGRectMake(10, 10, 600, 519);
            [self.viewLocHyderbad removeFromSuperview];
            [self.ViewLocations addSubview:self.viewLocHyderbad];

            [UIView transitionFromView:self.viewLocBangalore
                                toView:self.viewLocHyderbad
                              duration:0.9
                               options:UIViewAnimationOptionTransitionFlipFromBottom

                            completion:^(BOOL finished) {
                                NSLog(@"Locations View Appeared %@", Location); // getting this Log also, but View is missing
                            }];

        }




    }
