Objective c MapView注释未显示图像和详细信息披露按钮-iOS Mapkit Xcode 6目标C
我在地图视图中添加了两个注释,分别是带有图像的leftcalloutaccessoryview和带有详细信息披露按钮的RightCalloutAccessoryView。问题是它工作得很好,但只适用于一个注释,而不是两个注释。它显示一个带有图像和详细信息披露按钮的注释,可点击该按钮,而第二个注释仅显示标题、无图像和详细信息披露按钮,且无法点击。这是我的密码Objective c MapView注释未显示图像和详细信息披露按钮-iOS Mapkit Xcode 6目标C,objective-c,ios8,annotations,mkmapview,mapkit,Objective C,Ios8,Annotations,Mkmapview,Mapkit,我在地图视图中添加了两个注释,分别是带有图像的leftcalloutaccessoryview和带有详细信息披露按钮的RightCalloutAccessoryView。问题是它工作得很好,但只适用于一个注释,而不是两个注释。它显示一个带有图像和详细信息披露按钮的注释,可点击该按钮,而第二个注释仅显示标题、无图像和详细信息披露按钮,且无法点击。这是我的密码 -(void)viewDidLoad{ [super viewDidLoad]; myLocationManager=[[CLLoc

我做错了什么?它应该显示带有图像和细节披露按钮的多个注释。为什么它们只显示一个注释?有时第一个可以正常工作,有时第二个可以正常工作,但两者不能一起正常工作。您应该在viewForAnnotation方法中设置leftCalloutAccessoryView和rightCalloutAccessoryView属性,而不是didAddAnnotationViews。然后可以显示这两个注释
例如:
- (MKAnnotationView *)mapView:(MKMapView*)mapView
viewForAnnotation:(id <MKAnnotation>)annotation
{
if (annotation == mapView.userLocation) {
return nil;
}
MKPinAnnotationView *annotationView;
NSString *identifier = @"Pin";
annotationView = (MKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:identifier];
if (nil == annotationView) {
annotationView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:identifier];
}
UIImageView *iconView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"frame_blue.png"]];
annotationView.leftCalloutAccessoryView = iconView;
annotationView.rightCalloutAccessoryView = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
return annotaionView;
}
它奏效了,解决了我的问题。非常感谢你。
