您在屏幕上有注释。注释是纬度和经度值。

    NSArray *data = [root objectForKey:@"data"];
    for (NSArray *row in data) {
    NSNumber * latitude = [[row objectAtIndex:22]objectAtIndex:1];
    NSNumber * longitude = [[row objectAtIndex:22]objectAtIndex:2];
    NSString * crimeDescription = [row objectAtIndex:18];
    NSString * address = [row objectAtIndex:14];

    CLLocationCoordinate2D coordinate;
    coordinate.latitude = latitude.doubleValue;
    coordinate.longitude = longitude.doubleValue;
    MyLocation *annotation = [[MyLocation alloc] initWithName:crimeDescription address:address coordinate:coordinate] ;
    [_mapView addAnnotation:annotation];
}
