我解析此JSON文件(正常,它的工作原理與UITextFields):添加註解爲座標的MKMapView
{"longitude":["37.786793","39.388528"],"latitude":["-122.395416","-78.887734"]}
IND創建MapViews,以這種方式在相應註解:
NSArray *allKeys2 = [DictionaryMap allKeys];
for (int h = 0; h < [allKeys2 count]; h++) {
CGRect mapFrame = CGRectMake(400, e, 200, 110);
MKMapView *mapView2 = [[MKMapView alloc] initWithFrame:mapFrame];
[image1 addSubview:mapView2];
NSString *key2 = [allKeys2 objectAtIndex:i];
NSObject *obj2 = [DictionaryMap objectForKey:key2];
NSString *address = [NSString stringWithFormat:@"%@", obj2];
float stringFloat = [address floatValue];
float stringFloat2 = [key2 floatValue];
CLLocationCoordinate2D anyLocation;
anyLocation.longitude = stringFloat;
anyLocation.latitude = stringFloat2;
MKPointAnnotation *annotationPoint2 = [[MKPointAnnotation alloc] init]; annotationPoint2.coordinate = anyLocation;
annotationPoint2.title = @"Event";
annotationPoint2.subtitle = @"Microsoft's headquarters2";
[mapView2 addAnnotation:annotationPoint2];
[mapView2.userLocation setTitle:@"I am here"];
[mapView2.userLocation addObserver:self
forKeyPath:@"location"
options:(NSKeyValueObservingOptionNew|NSKeyValueObservingOptionOld)
context:NULL];
[mapView2 setShowsUserLocation:NO];
[MapViewArray addObject:mapView2];
if (MapViewArray == nil)MapViewArray = [[NSMutableArray alloc]init];
[MapViewArray addObject: mapView2];
}}
}while(g < f);
...我想要第一個地圖視圖顯示第一個座標引腳,第二個顯示第二對座標。但現在,它在所有地圖視圖上繪製了相同的引腳,分別對應於最後一個座標,而不是第一個和第二個。此方法適用於UITextField文本,所以我找不到問題。
請幫忙!!
編輯:
NSString *filenameMap = [NSString stringWithFormat:@"%@%@Map", destDir, NavBar.topItem.title];
NSString *MapPath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:@"%@Map", NavBar.topItem.title]];
[self.restClient loadFile:filenameMap intoPath:MapPath];
NSString *fileContentMap = [[NSString alloc] initWithContentsOfFile:MapPath];
SBJsonParser *parserMap = [[SBJsonParser alloc] init];
NSDictionary *dataMap = (NSDictionary *) [parserMap objectWithString:fileContentMap error:nil];
NSArray *MaparrayLongitude = [dataMap objectForKey:@"longitude"];
NSArray *MaparrayLatitude = [dataMap objectForKey:@"latitude"];
NSDictionary* DictionaryMap = [NSDictionary dictionaryWithObjects:MaparrayLatitude forKeys:MaparrayLongitude];
不,我實際上想創建許多地圖視圖,每個都有一個註釋。第一個地圖視圖具有第一個針腳座標,第二個地圖視圖具有第二個針腳座標... – Alessandro
看看我的編輯,我添加了用於解析文件的代碼,也許它有幫助,因爲您提供的代碼給了我錯誤(不兼容的ID) – Alessandro
我有一個NSMutableArray問題...解決了 – Alessandro
