我是 iPhone 编程的新手,我正在练习 MKMapView。但它显示的是未占用的数据。我有两个 ViewController。在第一个 ViewController 上,我们有一个按钮,下面是这样编写的编码:- 有两个数组具有如下所示的数据:- DetailArray:- inNetwork = true;
resName = taverna1;
statusColor = "#FF0000";
statusString = "30 MIN";
true = hasPromo;
},
{
false = hasPromo;
inNetwork = true;
resName = bungalow;
statusColor = 00FF00;
statusString = "NO WAIT";
},
{
inNetwork = true;
resName = "casa_nostra";
statusColor = 00FF00;
statusString = "NO WAIT";
true = hasPromo;
},
{
inNetwork = true;
resName = karebu;
statusColor = 00FF00;
statusString = "NO WAIT";
true = hasPromo;
}
**Annotation Array**
(
"<MyAnnotViewController: 0x8457b60>",
"<MyAnnotViewController: 0x845a040>",
"<MyAnnotViewController: 0x84439f0>",
"<MyAnnotViewController: 0x806f090>"
)
MyAnnoationViewcontroller 是 MKAnnotation 的子类。它成功包含标题和坐标。
SecondViewController *_SecondViewController =[[SecondViewController alloc]initWithNibName:@"SecondViewController" bundle:nil];
_SecondViewController.DetailArray = detailArray;
_SecondViewController.annotationArray = annotationArray;
[self.navigationController pushViewController:_SecondViewController animated:YES];
在 secondViewController 上:-
MKMapView * MapView =[[MKMapView alloc]initWithFrame:CGRectMake(0, 0, 320, 415)];
MapView.delegate =self;
MapView.showsUserLocation =NO;
[MapView addAnnotations:annotationArray];
[self.view addSubview:MapView];
在 Delegate 方法上,它在注释上显示出非常不确定的结果。氯化物和标题是所需的输出。但是第一个休息名称的颜色显示第二个餐厅的颜色,第二个显示任何其他颜色。请任何人帮助我摆脱这个问题。帮助将不胜感激。
