我已經將Google maps sdk for ios添加到我的iphone應用程序中，並且如果點擊信息窗口彈出標題，我有一些自定義標記，我如何在此信息窗口中添加一個按鈕，以便按下後會轉到新頁面？現在我試着用這個帖子來解決這個問題Adding Click Event on InfoWindow/Marker in Google Maps SDK for native iOS/objective C它不給我錯誤，但它不會工作。如何在ios上添加Google地圖標記信息窗口的按鈕？
這是我希望我的結果是：http://www.flickr.com/photos/[email protected]/6728157477/
爲您鏈接顯示的代碼使用MapKit的問題的答案，因此它不會與谷歌地圖SDK iOS版工作。
請參閱如何返回與谷歌地圖SDK自定義視圖爲iOS這個問題：
Custom annotation view in Google Maps SDK
但是請注意，根據這個問題，它看起來像所顯示的內容可能是一個視覺副本視圖不是實際的觀點，這可能會限制你的觀點做互動：
Add buttons to view returned by markerInfoWindow delegate method
簡單地檢測信息窗口的水龍頭，去一個不同儘管如此，頁面應該可以使用didTapWindowOfMarker。
注意，有一個在谷歌的問題跟蹤功能要求增加對這種直接支持：

此代碼不正是你想要的。它的靈感來自Saxon Druce推薦的link中的＃9，但做得不同而且更完整。它檢測添加到我的自定義infoWindow的按鈕上的點擊。我創建了一個帶有2個假按鈕的自定義infoWindow（它們實際上可以被圖像替代，因爲它們不會觸發任何動作），並且我在infoWindow上添加了一個透明的UIView，並帶有2個真實但透明的按鈕。這些按鈕將觸發這些操作。
最後，我使用幾個委託方法或KVC爲了在infoWindow本身移動時移動疊加的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;
}
可以請你介紹一下PointMapItem。無法從您的示例代碼中找出它。 – Aneesh 2016-10-13 05:53:56
1）創建一個你想在infoWindow中顯示的子視圖。 2）設置子視圖的框架等於infoWindow視圖的框架。
subView = [[[NSBundle mainBundle] loadNibNamed:@"viewName" owner:self options:nil] objectAtIndex:0];
[subView setFrame:infoview.frame];
[self.mapview addSubview:subView];
這是我用什麼： - （空）mapView：（GMSMapView *）mapView didTapInfoWindowOfMarker：（id）marker [0126]自我執行SegueWithIdentifier：@「ViewController」sender：[marker snippet]]; } 它不是一個很好的解決方案來替換按鈕，但它的工作原理！謝謝 –

User1810991，我試着用你的** performSegueWithIdentifier：**解決方案，但我得到一個錯誤。標識符（第一個參數）到底需要對應什麼？我通過包含視圖控制器進行匹配，但沒有工作 – 2013-12-20 21:29:27
嗨查理，它是segue的名稱 - 單擊segue（在故事板上的連接線），然後設置它的標識符。 – 2013-12-20 23:49:50
