在mkMapView ios中单击按钮发送对象
在我的Mapview中,我有一个sum注释,注释中有一个按钮,该按钮将我发送到另一个视图,以获取有关此注释的更多详细信息 我的代码是在mkMapView ios中单击按钮发送对象,ios,uibutton,mkmapview,mapkit,sender,Ios,Uibutton,Mkmapview,Mapkit,Sender,在我的Mapview中,我有一个sum注释,注释中有一个按钮,该按钮将我发送到另一个视图,以获取有关此注释的更多详细信息 我的代码是 myAnnotation *myAnn = (myAnnotation *)annotation; UIButton *discloseButton = [UIButton buttonWithType: UIButtonTypeDetailDisclosure]; [discloseButton addTarget: self action: @

如何通过单击填充我的表detailviewcontroller.DetailModal的按钮发送对象注释?使用mapview的委托方法:
-(void)地图视图:(MKMapView*)地图视图注释视图:(MKAnnotationView*)视图调用访问控制点击:(UIControl*)控制
而不是您自己分配给按钮的操作 功能示例代码:
#import "ViewController.h"
#import <MapKit/MapKit.h>
@interface ViewController () <MKMapViewDelegate>
@end
@interface Test : NSObject<MKAnnotation>
@property MKMapView *mapView;
@end
@implementation Test
-(NSString *)title {
return @"test";
}
- (CLLocationCoordinate2D)coordinate {
return self.mapView.centerCoordinate;
}
@end
@implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
MKMapView *mapView = [[MKMapView alloc] initWithFrame:self.view.bounds];
mapView.delegate = self;
[self.view addSubview:mapView];
Test *test = [[Test alloc] init];
test.mapView = mapView;
[mapView addAnnotation:test]; //just as a test
}
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation {
MKAnnotationView *annotationView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"test"];
UIButton *discloseButton = [UIButton buttonWithType: UIButtonTypeDetailDisclosure];
discloseButton.tag = 1;
annotationView.canShowCallout = YES;
annotationView.rightCalloutAccessoryView = discloseButton;
return annotationView;
}
- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control {
NSLog(@"annotationView %@", view);
NSLog(@"tag of click %d", control.tag);
NSLog(@"annotation %@", view.annotation);
}
@end
#导入“ViewController.h”
#进口
@界面视图控制器()
@结束
@接口测试:NSObject
@属性MKMapView*mapView;
@结束
@实施测试
-(NSString*)标题{
返回@“测试”;
}
-(CLLocationCoordinate2D)坐标{
返回self.mapView.centerCoordinate;
}
@结束
@实现视图控制器
-(无效)viewDidLoad
{

MKMapView*mapView=[[MKMapView alloc]initWithFrame:self.view.bounds];
mapView.delegate=self;
[self.view addSubview:mapView];
Test*Test=[[Test alloc]init];
test.mapView=mapView;
[mapView addAnnotation:test];//就像测试一样
}
-(MKAnnotationView*)地图视图:(MKMapView*)地图视图注释:(id)注释{
MKAnnotationView*annotationView=[[MKPinAnnotationView alloc]initWithAnnotation:annotation重用标识符:@“test”];
UIButton*DispositionButton=[UIButton Button类型:UIButtonTypedTailDisposition];
dispositeButton.tag=1;

您可以将所有数据发送到格式化字符串,并在prepareforsgue
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([[segue identifier] isEqualToString:@"aa"])
{
UIButton *button = (UIButton *)sender;
NSArray* infos = [button.accessibilityHint componentsSeparatedByString: @"::"];
if ([infos count] > 1)
{
tit = [infos objectAtIndex:0];
description = [infos objectAtIndex:1];
Latitude = [infos objectAtIndex:2];
longitude = [infos objectAtIndex:3];
image = [infos objectAtIndex:4];
type = [infos objectAtIndex:5];
ville = [infos objectAtIndex:6];
point = [infos objectAtIndex:7];
nombreDeVisite = [infos objectAtIndex:8];
nbVTotal = [infos objectAtIndex:9];
idMission = [infos objectAtIndex:10];
}
DetailViewController *detailviewcontroller = [segue destinationViewController];
detailviewcontroller.DetailModal = @[tit,description,Latitude,longitude,image,type,ville,point,nombreDeVisite,nbVTotal,idMission];
}
}
代码是这样的
myAnnotation *myAnn = (myAnnotation *)annotation;
UIButton *discloseButton = [UIButton buttonWithType: UIButtonTypeDetailDisclosure];
[discloseButton addTarget: self action: @selector(showInfo:) forControlEvents: UIControlEventTouchUpInside];
NSString *detail = [NSString stringWithFormat:@"%@::%@::%@::%@::%@::%@::%@::%@::%@::%@::%@"
,myAnn.title,myAnn.description,myAnn.Latitude,myAnn.longitude,myAnn.image,myAnn.type,myAnn.ville,myAnn.point,myAnn.nombreDeVisite,myAnn.nbVTotal,myAnn.idMission];
discloseButton.accessibilityHint = detail;
annotationView.rightCalloutAccessoryView = discloseButton;
在您的函数中prepareForSegue
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([[segue identifier] isEqualToString:@"aa"])
{
UIButton *button = (UIButton *)sender;
NSArray* infos = [button.accessibilityHint componentsSeparatedByString: @"::"];
if ([infos count] > 1)
{
tit = [infos objectAtIndex:0];
description = [infos objectAtIndex:1];
Latitude = [infos objectAtIndex:2];
longitude = [infos objectAtIndex:3];
image = [infos objectAtIndex:4];
type = [infos objectAtIndex:5];
ville = [infos objectAtIndex:6];
point = [infos objectAtIndex:7];
nombreDeVisite = [infos objectAtIndex:8];
nbVTotal = [infos objectAtIndex:9];
idMission = [infos objectAtIndex:10];
}
DetailViewController *detailviewcontroller = [segue destinationViewController];
detailviewcontroller.DetailModal = @[tit,description,Latitude,longitude,image,type,ville,point,nombreDeVisite,nbVTotal,idMission];
}
}
这是一个极其粗糙和脆弱的解决方案。分隔的详细信息字符串是完全不必要的,而且非常不面向对象。它完全违背了OP定义的自定义注释类对象
myAnnotation
