我已经将Google maps sdk for ios添加到我的iphone应用程序中，并且如果点击信息窗口弹出标题，我有一些自定义标记，我如何在此信息窗口中添加一个按钮，以便按下后会转到新页面？现在我试着用这个帖子来解决这个问题Adding Click Event on InfoWindow/Marker in Google Maps SDK for native iOS/objective C它不给我错误，但它不会工作。如何在ios上添加Google地图标记信息窗口的按钮？

为您链接显示的代码使用MapKit的问题的答案，因此它不会与谷歌地图SDK iOS版工作。
请参阅如何返回与谷歌地图SDK自定义视图为iOS这个问题：
Custom annotation view in Google Maps SDK
但是请注意，根据这个问题，它看起来像所显示的内容可能是一个视觉副本视图不是实际的观点，这可能会限制你的观点做互动：
Add buttons to view returned by markerInfoWindow delegate method
简单地检测信息窗口的水龙头，去一个不同尽管如此，页面应该可以使用didTapWindowOfMarker。
注意，有一个在谷歌的问题跟踪功能要求增加对这种直接支持：

此代码不正是你想要的。它的灵感来自Saxon Druce推荐的link中的＃9，但做得不同而且更完整。它检测添加到我的自定义infoWindow的按钮上的点击。我创建了一个带有2个假按钮的自定义infoWindow（它们实际上可以被图像替代，因为它们不会触发任何动作），并且我在infoWindow上添加了一个透明的UIView，并带有2个真实但透明的按钮。这些按钮将触发这些操作。
最后，我使用几个委托方法或KVC为了在infoWindow本身移动时移动叠加的UIView。
- (UIView *)mapView:(GMSMapView *)mapView markerInfoWindow:(GMSMarker *)marker {
[self.actionOverlayCalloutView removeFromSuperview];
UIView *calloutView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, infoWindowWidth, infoWindowHeight)];
float offset = anchorSize * M_SQRT2;
CGAffineTransform rotateBy45Degrees = CGAffineTransformMakeRotation(M_PI_4);
UIView *arrow = [[UIView alloc] initWithFrame:CGRectMake((infoWindowWidth - anchorSize)/2.0, infoWindowHeight - offset, anchorSize, anchorSize)];
arrow.transform = rotateBy45Degrees;
arrow.backgroundColor = [UIColor lightGrayColor];
[calloutView addSubview:arrow];
UIView *contentView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, infoWindowWidth, infoWindowHeight - offset/2)];
[contentView setBackgroundColor:[UIColor whiteColor]];
contentView.layer.cornerRadius = 5;
contentView.layer.masksToBounds = YES;
contentView.layer.borderColor = [UIColor lightGrayColor].CGColor;
contentView.layer.borderWidth = 1.0f;
self.actionOverlayCalloutView =
[NSKeyedUnarchiver unarchiveObjectWithData:[NSKeyedArchiver archivedDataWithRootObject:contentView]]; //hack to copy a view...
self.actionOverlayCalloutView.backgroundColor = [UIColor lightGrayColorWithAlpha:0.5];
self.actionOverlayCalloutView.layer.cornerRadius = 5;
NSMutableArray *falseButtons = [NSMutableArray array];
NSMutableArray *actionButtons = [NSMutableArray array];
PointMapItem *pointAnnotation = marker.userData;
if ([pointAnnotation canPerformSend]) {
UIButton *button = [[UIButton alloc] init];
[button setImage:[UIImage imageNamed:@"imageButton1.png"] forState:UIControlStateNormal];
[falseButtons addObject:button];
UIButton *activableButton = [[UIButton alloc] init];
[activableButton addTarget:self action:@selector(onButton1Clicked) forControlEvents:UIControlEventTouchUpInside];
[actionButtons addObject:activableButton];
}
if ([pointAnnotation canPerformShowDetails]) {
UIButton *button = [[UIButton alloc] init];
[button setImage:[UIImage imageNamed:@"imageButton1.png"] forState:UIControlStateNormal];
[falseButtons addObject:button];
UIButton *activableButton = [[UIButton alloc] init];
[activableButton addTarget:self action:@selector(onButton2Clicked) forControlEvents:UIControlEventTouchUpInside];
[actionButtons addObject:activableButton];
}
int buttonWidth = contentView.frame.size.width/[falseButtons count];
int currentOffset = 0;
for (int i=0; i<falseButtons.count; i++) {
UIButton *falseButton = [falseButtons objectAtIndex:i];
UIButton *activableButton = [actionButtons objectAtIndex:i];
[falseButton setFrame:CGRectMake(currentOffset, 0, buttonWidth, contentView.frame.size.height)];
currentOffset += buttonWidth;
activableButton.frame = falseButton.frame;
[activableButton setTitle:@"" forState:UIControlStateNormal];
[self.actionOverlayCalloutView addSubview:activableButton];
[contentView addSubview:falseButton];
}
[calloutView addSubview:contentView];
CLLocationCoordinate2D anchor = [self.mapView.selectedMarker position];
CGPoint point = [self.mapView.projection pointForCoordinate:anchor];
point.y -= self.mapView.selectedMarker.icon.size.height + offset/2 + (infoWindowHeight - offset/2)/2;
self.actionOverlayCalloutView.center = point;
[self.mapView addSubview:self.actionOverlayCalloutView];
return calloutView;
}
- (void)mapView:(GMSMapView *)pMapView didChangeCameraPosition:(GMSCameraPosition *)position {
if (pMapView.selectedMarker != nil && self.actionOverlayCalloutView.superview) {
CLLocationCoordinate2D anchor = [self.mapView.selectedMarker position];
CGPoint point = [self.mapView.projection pointForCoordinate:anchor];
float offset = anchorSize * M_SQRT2;
point.y -= self.mapView.selectedMarker.icon.size.height + offset/2 + (infoWindowHeight - offset/2)/2;
self.actionOverlayCalloutView.center = point;
} else {
[self.actionOverlayCalloutView removeFromSuperview];
}
}
- (void)mapView:(GMSMapView *)mapView didTapAtCoordinate:(CLLocationCoordinate2D)coordinate {
[self.actionOverlayCalloutView removeFromSuperview];
}
- (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context {
if ([keyPath isEqualToString:@"mapView.selectedMarker"]) {
if (!self.mapView.selectedMarker) {
[self.actionOverlayCalloutView removeFromSuperview];
}
}
}
- (void)onButton2Clicked {
//your code
self.mapView.selectedMarker = nil;
}
- (void)onButton1Clicked {
// your code;
self.mapView.selectedMarker = nil;
}
可以请你介绍一下PointMapItem。无法从您的示例代码中找出它。 – Aneesh 2016-10-13 05:53:56
1）创建一个你想在infoWindow中显示的子视图。 2）设置子视图的框架等于infoWindow视图的框架。
subView = [[[NSBundle mainBundle] loadNibNamed:@"viewName" owner:self options:nil] objectAtIndex:0];
[subView setFrame:infoview.frame];
[self.mapview addSubview:subView];
这是我用什么： - （空）mapView：（GMSMapView *）mapView didTapInfoWindowOfMarker：（id）marker [0126]自我执行SegueWithIdentifier：@“ViewController”sender：[marker snippet]]; } 它不是一个很好的解决方案来替换按钮，但它的工作原理！谢谢 –

User1810991，我试着用你的** performSegueWithIdentifier：**解决方案，但我得到一个错误。标识符（第一个参数）到底需要对应什么？我通过包含视图控制器进行匹配，但没有工作 – 2013-12-20 21:29:27
嗨查理，它是segue的名称 - 单击segue（在故事板上的连接线），然后设置它的标识符。 – 2013-12-20 23:49:50
