I've had some past experience using MKMapView and MKPointAnnotation , which I used to put some pin on a map. This time I am trying to go one step further and use MKPinAnnotationView , to write a label along with some of the pins. Unfortunately, it doesn't all work as I expect. Here is what I want to do: I have a map (an MKMapView object) and when I touch it, I put a pin at the touch point, then some computation is performed and this gives me a second point on the map. I put a second pin on the map (located at the second point), on this last pin I want to put a label, say "Hello Second!", but

问题 I'm trying to follow a car on a map view. This code should animate the car and the map with the same speed, so that the annotation view always appears in the center: [UIView beginAnimations:nil context:NULL]; [UIView setAnimationCurve:UIViewAnimationCurveLinear]; [UIView setAnimationDuration: 1.0]; [UIView setAnimationBeginsFromCurrentState:YES]; [car setCoordinate:coord]; [mapView setCenterCoordinate:coord]; [UIView commitAnimations]; It worked fine in iOS 5. In iOS 6 the map is not

问题 I have a mapview that displays locations of cash points. Annotations are dropped and the callout can be clicked on to go to a page with more detail about that location. There are two categories of cashpoint, free and paid, free cashpoint pins are green and the other red. When the pins drop they are the correct colours. Everything works fine untill i zoom to user location or other areas of the map then when i go back to the pins they have lost their colour formatting and are all the original

iphone mapview bring first and last annotation to the front

由 流过昼夜 提交于 2019-12-08 16:45:58
问题 I need some code which can be used outside of the mk* functions. I need to run my custom function to bring the FIRST and LAST markers in an array to the front. (so on top of all the other markers on my screen). I have tried [self.view bringSubviewToFront:[[mapView annotations]objectAtIndex: 0]]; I have used [[mapView annotations]objectAtIndex: 0] in my code and that works, but it crashes when I try to bring this to the front. Am I accessing the wrong layer or something? thanks for any help.
