添加按钮以查看markerInfoWindow委托方法返回的视图 [英] Add buttons to view returned by markerInfoWindow delegate method

问题描述

我当前正在通过将委托设置为self并使用以下代码来使用google maps ios SDK创建并返回自定义视图.

I'm currently creating and returning a custom view with the google maps ios SDK by setting delegate to self and using the following code.

#pragma mark - GMSMapViewDelegate
-(UIView*)mapView:(GMSMapView *)mapView markerInfoWindow:(id<GMSMarker>)marker {
    int popupWidth = 200;
    int contentWidth = 180;
    int contentPad = 10;
    int popupHeight = 140;
    int popupBottomPadding = 16;
    int popupContentHeight = popupHeight - popupBottomPadding;
    int buttonHeight = 30;

    UIView *outerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, popupWidth, popupHeight)];

    UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, popupWidth, popupContentHeight)];
    [view setBackgroundColor:[UIColor whiteColor]];

    UILabel *titleLabel = [[UILabel alloc] initWithFrame:CGRectMake(contentPad, 0, contentWidth, 22)];
    [titleLabel setFont:[UIFont systemFontOfSize:17.0]];
    titleLabel.text = [marker title];

    UILabel *descriptionLabel = [[UILabel alloc] initWithFrame:CGRectMake(contentPad, 24, contentWidth, 20)];
    [descriptionLabel setFont:[UIFont systemFontOfSize:11.0]];
    descriptionLabel.text = [marker snippet];

    [view addSubview:titleLabel];
    [view addSubview:descriptionLabel];

    UIButton *directionButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    directionButton.frame = CGRectMake(contentPad, 45, contentWidth, buttonHeight);
    [directionButton setTitle:@"Directions" forState:UIControlStateNormal];
    [directionButton addTarget:self action:@selector(directionsPressed) forControlEvents:UIControlEventTouchDown];

    UIButton *viewLocationButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    [viewLocationButton addTarget:self action:@selector(viewLocationPressed) forControlEvents:UIControlEventTouchUpInside];
    [viewLocationButton setTitle:@"View Location" forState:UIControlStateNormal];
    viewLocationButton.frame = CGRectMake(contentPad, 80, contentWidth, buttonHeight);

    // handle bottom dealio
    UIImage *bottomImage = [UIImage imageNamed:@"map-pointer-bottom"];
    UIImageView *bottomView = [[UIImageView alloc] initWithFrame:CGRectMake((popupWidth / 2) - (bottomImage.size.width / 2), (popupContentHeight), bottomImage.size.width, bottomImage.size.height)];
    [bottomView setImage:bottomImage];

    [outerView addSubview:view];
    [outerView addSubview:bottomView];
    [outerView addSubview:directionButton];
    [outerView addSubview:viewLocationButton];

    ListItem *li = (ListItem*)[marker userData];
    self.currentItem = li;
    NSLog(@"List Item %@ - %@", li.type, li.typeid);

    return outerView;
}

-(void)directionsPressed {
    NSLog(@"Directions Pressed");
}

-(void)viewLocationPressed {
    NSLog(@"Location View Pressed");
}

- (void)mapView:(GMSMapView *)mapView didTapInfoWindowOfMarker:(id<GMSMarker>)marker {
    NSLog(@"Tap Captured");
}

当我点击自定义视图时，didTapWindowOfMarker被触发，但是按钮的目标方法都没有被触发.

The didTapWindowOfMarker is being fired when i tap the custom view, but neither of the target methods for the buttons are being fired.

关于为什么会这样的任何想法?

Any ideas for why this might be?

推荐答案

可能，正如Google Maps Android API文档中正式提到的那样，以下有关 infowindows 的限制也适用于Google Maps iOS SDK:

Possibly, as mentioned officially in documentation of Google Maps Android API, the below restriction regarding infowindows applies to Google Maps iOS SDK also :

信息窗口不是实时视图，而是将视图作为图像渲染到地图上.结果，您在视图上设置的所有侦听器都将被忽略，并且您无法区分视图各个部分上的单击事件.建议您不要在自定义信息窗口中放置交互式组件，例如按钮，复选框或文本输入.

Info window is not a live View, rather the view is rendered as an image onto the map. As a result, any listeners you set on the view are disregarded and you cannot distinguish between click events on various parts of the view. You are advised not to place interactive components — such as buttons, checkboxes, or text inputs — within your custom info window.

因此，基本上，单击信息窗口的任何部分都只会触发" didTapWindowOfMarker "

So basically clicking on any part of the infowindow will trigger only "didTapWindowOfMarker"
