由 南笙酒味 提交于 2019-12-08 08:24:33
问题 I've a question about doing a local search in Apple maps which I have already implemented into my app. The app should show the user where are "supermarkets" around him. My mapView also shows the user's current location but I don't really know how I should do this with the results of the market-locations. Maybe Apple provides a solution/advice for this. Thanks in advance. The results (supermarkets) should be displayed as in this picture. UPDATE: The function works perfectly but is it also

Rotating only the MapView's content

由 断了今生、忘了曾经 提交于 2019-12-08 05:42:06
问题 I am trying to rotate a map view in my app according the the user's current route. (I don't like to use the built in compasse because only 3GS uses it and it suffers too much interference from other machines, i.e. your own car.). the CGAffineTransformMakeRotation method will rotate the Whole Map View, so the Google Logo will not be in the lower right of the screen anymore. Also all Annotation Views will rotate and look weird on the App. Does anyone knows how to rotate just the content

MKAnnotationView Subviews

问题 Currently, I am having an issue with my project in implementing a custom MKAnnotationView that has multiple custom UIImageViews. So these custom UIImageViews have a clear button on top of them to not have to add gesture recognizers. As you can see, it would be beneficial to actually tap the MKAnnotationView subviews and have some action happen. I implemented a protocol for the MKAnnotationView where each image subview within the MKAnnotationView makes a callback to the controller that is the
