自定义信息窗口上的按钮未在ios中接收操作

Question

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 <UIKit/UIKit.h>

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

并在infoWindow.xib中添加了

• UILabel名为addressLabel
• UIButton名为button

ViewController.h

#import "CustomInfoWindow.h"

@interface viewController : UIViewController<GMSMapViewDelegate>
{
  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方法无法触发。

我还没有使用谷歌地图SDK，但在看了几个链接后，你似乎想要完成的事情似乎并不容易。

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。}

引用：

  

注意：绘制的信息窗口不是实时视图。观点是   在它的时候呈现为图像（使用View.draw(Canvas)）   回。这意味着对视图的任何后续更改都不会   通过地图上的信息窗口反映出来。更新信息窗口   稍后（例如，在图片加载后），请致电showInfoWindow()。   此外，信息窗口不会考虑任何交互性   典型的普通视图，如触摸或手势事件。不管你   可以在整个信息窗口上收听通用点击事件   在下面的部分中描述。

您可以改为实施GMSMapViewDelegate's -didTapInfoWindowOfMarker:委托方法来检查信息窗是否被点击 （缺点是整个infowindow变成一个按钮）

看看你的这段代码 -

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

在这里我猜你的按钮名称应该以大写字母＆＃34; B＆＃34;如： -

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

因为你有@property（非原子）IBOutlet UIButton * Button;

Answer 3

• 首先在.h头文件中写下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，而且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。如果按钮被放置在视图的旁边，那么它会被修剪掉。

更改此

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

到

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

在ButtonPressed课程中声明CustomInfoWindow。

Answer 5

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 <UIKit/UIKit.h>
#import <GoogleMaps/GoogleMaps.h>

#import "CustomInfoWindow.h"

@interface Map_ViewController : UIViewController <GMSMapViewDelegate>{
    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;

1. 使用按钮创建一个子视图。

2. 将infoWindow视图的框架分配给子视图框架。

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

Swift 3.0解决方案

首先设置mapView（GMSMapViewDelegate）的委托

 //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（customInfoWindow）的出口放在具有mapView的同一控制器中。
