I have an MKMapView which has about 700 annotations which represent bus-lines. That implies, they are not images, but are drawn as lines.
In iOS 3 this worked fine. When the user changed the zoom level, these lines did no longer match their streets, but in mapView:regionDidChangeAnimated: I sent a redisplay message to each and all was fine again. Now in 4.0.1 the same app crashes a lot on the device (not in the simulator). The only way to make it work is: 1. in mapView:regionWillChangeAnimated: use removeAnnotations: 2. in mapView:regionDidChangeAnimated: use addAnnotations: again. 3. wait until the bus-lines reappear (a few seconds) then do the next change of region. (This is of course absolutely not acceptable for the finished product.) The crash shows lines like: CoreAnimation: failed to allocate 17668064 bytes CoreAnimation: failed to allocate 11728192 bytes CoreAnimation: failed to allocate 10071488 bytes and lots of similar lines following. Often followed by: iBus 1(476,0x3e7037c8) malloc: *** mmap(size=122880) failed (error code=12) *** error: can't allocate region *** set a breakpoint in malloc_error_break to debug Any ideas? What code would I need to show?
