iOS 8 MKAnnotationView rightCalloutAccessoryView未对齐 [英] iOS 8 MKAnnotationView rightCalloutAccessoryView misaligned

问题描述

我对iOS内容一般都很陌生，在测试我们的App for iOS 8兼容性时发现了一个问题。
在iOS 7中一切正常，但在iOS 8上，rightCalloutAccessoryView在某些情况下未对齐。

I'm still pretty new to the iOS stuff in general and found a problem while testing our App for iOS 8 compatibility. In iOS 7 everything worked fine but on iOS 8 the rightCalloutAccessoryView is misaligned under certain circumstances.

第一个屏幕截图：正确对齐

First Screenshot: Correctly aligned

第二个屏幕截图：错误对齐

Second Screenshot: Wrong alignment

如您所见，问题发生在InfoWindow标题较长时。但是在iOS 7上并非如此，我找不到任何提及这已经发生变化的事情？

As you can see, the problem takes place when the InfoWindow has a long title. But this was not the case on iOS 7 and I couldn't find anything mentioning this has changed?

我试图了解原因并找到解决方法，但是找不到任何东西。
我们自己可以解决这个问题吗？还是我们必须为Apple提出问题？

I tried to understand why and find a way to resolve this, but couldn't find anything yet. Is this solvable on our own or do we have to file an issue for Apple?

任何帮助/想法都会受到高度赞赏，因为我在某种程度上受到过度挑战有这个问题。

Any help/ideas would be highly appreciated as I'm somehow overchallenged with this problem.

添加MKAnnotationViews的代码

Code which adds the MKAnnotationViews

- (MKAnnotationView *)viewForStation:(id<MKAnnotation>)annotation {
      static NSString *stationIdentifier = @"stao";
      MKAnnotationView *annotationView = [self.mapView dequeueReusableAnnotationViewWithIdentifier:stationIdentifier];
      if (annotationView == nil) {
          annotationView = [[MKAnnotationView alloc] initWithAnnotation:annotation           reuseIdentifier:stationIdentifier];
          annotationView.image = [UIImage bundleImageNamed:PIN_IMAGE];
          annotationView.canShowCallout = YES;
          annotationView.rightCalloutAccessoryView = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
      }
      return annotationView;
}

您可能感兴趣，我（刚才）也将此问题添加到apple.developer.com上的iOS 8测试版部分： https://devforums.apple.com / thread / 242282？tstart = 0

As you may be interested, I (just now) also added this question to the iOS 8 Beta section on apple.developer.com: https://devforums.apple.com/thread/242282?tstart=0

如果我在这里或在apple.developer.com上得到答案，我会反映它，以便我们可以找到它在两个网站上

If I get an answer either here or on apple.developer.com I will reflect it so we can find it on both sites

推荐答案

我通过设置autoresizingmask来解决这个问题，以修复水平bug的垂直bug和frame.size.width

I solved this by setting the autoresizingmask to fix the vertical bug and frame.size.width for the horizontal bug

UIButton* infoButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
[infoButton setFrame:CGRectMake(0, 0, CGRectGetWidth(infoButton.frame)+10, CGRectGetHeight(infoButton.frame))];
[infoButton setAutoresizingMask:UIViewAutoresizingFlexibleBottomMargin|UIViewAutoresizingFlexibleTopMargin];
[annotationView setRightCalloutAccessoryView:infoButton];
