Question

好的我有1个表视图，1个详细视图和1个地图视图，目标是使地图具有取决于所选单元格的特定坐标。我试图使用相同的方法我在详细视图中更改文本，但它似乎没有工作。好的，这里是代码...

tableview .m

    latitude = [[NSArray alloc] initWithObjects:[NSNumber numberWithDouble:52.52314],[NSNumber numberWithDouble:52.52314],[NSNumber numberWithDouble:52.52314],[NSNumber numberWithDouble:52.52314],nil];
longitude = [[NSArray alloc] initWithObjects:[NSNumber numberWithDouble:-1.884799],[NSNumber numberWithDouble:-18.884799],[NSNumber numberWithDouble:-1.884799],[NSNumber numberWithDouble:-1.884799], nil];

[self.mapController changeLat:[latitude objectAtIndex:indexPath.row]];
[self.mapController changeLong:[longitude objectAtIndex:indexPath.row]];

mapView .m

 - (IBAction) changeLat:(NSNumber *)str {   
lati = str;
}

- (IBAction) changeLong:(NSNumber *)str {   
longi = str;
}
  MKCoordinateRegion region = {{0.0, 0.0}, {0.0, 0.0}};

   region.center.latitude = [lati doubleValue];
      region.center.longitude = [longi doubleValue];

    [mapView setRegion:region animated:YES];

我真的坚持了下来：S

将地图坐标作为变量的问题
