自定义信息窗口上的按钮未在ios中接收操作

我在iOS应用程序中使用谷歌地图，并实现了一个自定义信息窗口，用于显示标记的标题。
现在，我在该自定义信息窗口上添加了一个按钮，但我的问题是没有调用按钮操作方法。

CustomInfoWindow.h

#import  @interface CustomInfoWindow : UIView @property (nonatomic,weak) IBOutlet UILabel *addressLabel; @property(nonatomic) IBOutlet UIButton *button; @end 

在infoWindow.xib ，我添加了

• UILabel称为addressLabel
• UIButton称为button

ViewController.h

 #import "CustomInfoWindow.h" @interface viewController : UIViewController { GMSMapView *mapView; } @end 

ViewController.m

 - (UIView *)mapView:(GMSMapView *)mapView markerInfoWindow:(GMSMarker *)marker { NSLog(@"Mrker Tapped"); CustomInfoWindow *infoWindow = [[[NSBundle mainBundle]loadNibNamed:@"infoWindow" owner:self options:nil] objectAtIndex:0]; infoWindow.addressLabel.text = marker.title; [infoWindow.button addTarget:self action:@selector(ButtonPressed) forControlEvents:UIControlEventTouchUpInside]; return infoWindow; } -(void)ButtonPressed { NSLog(@"Button Pressed"); } 

基本上…… ButtonPressed方法不会触发。

我没有使用谷歌地图SDK但是在看了几个链接之后，看起来你想要完成的事情可能并不容易。

参考： https ： //developers.google.com/maps/documentation/android/infowindows
_{PS：这可能是Android文档，但它似乎也适用于iOS。}

去引用：

注意：绘制的信息窗口不是实时视图。 视图在返回时呈现为图像（使用View.draw(Canvas) ）。 这意味着对视图的任何后续更改都不会被地图上的信息窗口反映出来。 要稍后更新信息窗口（例如，在加载图像后），请调用showInfoWindow() 。 此外，信息窗口将不会考虑正常视图（例如触摸或手势事件）的任何典型交互性。 但是，您可以在整个信息窗口中收听通用点击事件，如下节所述。

您可以改为实现GMSMapViewDelegate的-didTapInfoWindowOfMarker:委托方法来检查信息-didTapInfoWindowOfMarker:是否被点击。
（ 缺点是整个infowindow成为一个按钮 ）

看看你的这个代码 –

 [infoWindow.button addTarget:self action:@selector(ButtonPressed) forControlEvents:UIControlEventTouchUpInside]; 

在这里我想你的按钮名称应该以大写“B”开头： –

 [infoWindow.Button addTarget:self action:@selector(ButtonPressed) forControlEvents:UIControlEventTouchUpInside]; 

因为你有@property（非primefaces）IBOutlet UIButton * Button;

• 首先在.h头文件中写入CustomInfoWindow *infoWindow它的属性。

• 然后在.m类文件中合成，然后尝试添加目标

Answer 4

我认为infoWindow太小了，它上面的按钮放在它外面。

尝试检查infoWindow的框架。 您还可以将任何背景颜色应用于infoWindow。 或者做infoWindow.clipToBounds=YES 。 如果按钮放在视图的旁边，则会明确地剪裁。

改变这个

 [infoWindow.button addTarget:self action:@selector(ButtonPressed) forControlEvents:UIControlEventTouchUpInside]; 

至

 [infoWindow.button addTarget:infoWindow action:@selector(ButtonPressed) forControlEvents:UIControlEventTouchUpInside]; 

并在CustomInfoWindow类中声明ButtonPressed 。

Swift 3.0解决方案

首先设置mapView的委托（GMSMapViewDelegate）

  //empty the default infowindow func mapView(_ mapView: GMSMapView, markerInfoWindow marker: GMSMarker) -> UIView? { return UIView() } // reset custom infowindow whenever marker is tapped func mapView(_ mapView: GMSMapView, didTap marker: GMSMarker) -> Bool { customInfoView.removeFromSuperview() // customInfoView.button.addTarget(self, action: #selector(buttonTapped(_:)), for: .touchUpInside) self.view.addSubview(customInfoView) // Remember to return false // so marker event is still handled by delegate return false } // let the custom infowindow follows the camera func mapView(_ mapView: GMSMapView, didChange position: GMSCameraPosition) { if (locationMarker != nil){ let location = locationMarker.position customInfoView.center = mapView.projection.point(for: location) } } // take care of the close event func mapView(_ mapView: GMSMapView, didTapAt coordinate: CLLocationCoordinate2D) { customInfoView.removeFromSuperview() } 

并将此视图的出口（customInfoWindow）放在具有mapView的同一控制器中。

您无法在infoWindow中添加按钮。

为此，您必须创建自己的自定义信息窗口，并在其中添加按钮。

map_ViewController.h

 #import  #import  #import "CustomInfoWindow.h" @interface Map_ViewController : UIViewController { BOOL canHideInfoWindow; } @property (strong, nonatomic) IBOutlet GMSMapView *map; @property (strong, nonatomic) CustomInfoWindow *displayedInfoWindow; @property BOOL markerTapped; @property BOOL cameraMoving; @property BOOL idleAfterMovement; @property (strong, nonatomic) GMSMarker *currentlyTappedMarker; @property (assign, nonatomic) CLLocationCoordinate2D position; @end 

Map_ViewController.m

 #import "Map_ViewController.h" @interface Map_ViewController () @end @implementation Map_ViewController #pragma mark - viewDidLoad - (void)viewDidLoad { [super viewDidLoad]; //get user position, i wont put all the code, only the code necessary for this topic self.position =CLLocationCoordinate2DMake(POSITION);

[self.view addSubview:self.displayedInfoWindow]; } } -(void)YOURBUTTONFUNCTION:(UIButton *)sender{ NSLog(@"YOURBUTTONFUNCTION TAPPED"); } @end

1. 使用按钮创建一个子视图。

2. 将infoWindow视图的帧分配给子视图帧。

    [subView setFrame:infoview.frame]; subView = [[[NSBundle mainBundle] loadNibNamed: owner:self options:nil] objectAtIndex:0]; [self.mapview addSubview:subView];
