UISwitch无法在iOS版Google Maps SDK上使用吗? [英] UISwitch doesn't work on Google Maps SDK for iOS?

问题描述

我正在尝试为我的iOS应用创建一个放置在Google Maps的mapView_上的UISwitch，但似乎不起作用.

I'm trying to create a UISwitch laid on mapView_ of Google Maps for my iOS app, but it seems not to work.

详细来说，我首先按照Google的指示进行操作，创建了mapView_，然后将其设为我的viewcontroller视图:

In details, I first followed instruction from google, created mapView_, then made it my viewcontroller's view:

self.view = mapView_;

然后，我以编程方式创建了一个UISwitch并将其添加为子视图:

Then, I created an UISwitch programmatically and added it as a subview:

mySwitch = [[UISwitch alloc] initWithFrame:CGRectMake(50, 360, 0, 0)];
[mySwitch setBackgroundColor:[UIColor clearColor]];
[mySwitch addTarget:self
             action:@selector(changeSwitch:)
        forControlEvents:UIControlEventTouchDown];
[mapView_ addSubview:mySwitch];

但是当我同时触摸模拟器和设备中的开关时，它并没有从ON-> OFF或OFF-> ON更改其状态.我什至尝试了其他UIControlEvent，例如UIControlEventValueChanged，但没有用.为了确保代码能正常工作，我尝试使用普通测试viewcontroller的普通视图(这意味着，不使用google maps)，效果很好！

But when I touched the switch both in simulator and device, it didn't change its state from ON->OFF or OFF->ON. I even tried different UIControlEvent, such as UIControlEventValueChanged but it didn't work. To make sure that the code should work, I tried on a normal view of a normal test viewcontroller (that means, not using google maps), it worked fine!

有人对此问题有何评论?

Does anyone have any comment about this issue?

感谢堆！

推荐答案

您可以通过将UISwitch和GMSMapView都添加到单个UIView父级来解决此问题，而不是将UISwitch添加为GMSMapView的子级.是的，这意味着您需要同时放置GMSMapView和UISwitch.

You can work around this issue by adding both the UISwitch and the GMSMapView to a single UIView parent, instead of adding the UISwitch as a child of a GMSMapView. Yes, this means you need to position both the GMSMapView and the UISwitch.
