Problem with zooming in

[tolgabakkaloglu]

thanks for the code first of all. I'm having an issue with zooming in when selecting a cluster. In select annotation delegate method, I managed to select cluster and zoom in to a specific level. But, at a certain level it doesn't allow me to zoom in more. For example, there is a cluster which grouped 4 annotations. When I select that cluster, map zooms in and break the cluster into 2 separate annotations and 1 cluster. Then I select the cluster, it doesn't zoom in. I played with zooming rate and found that it lets me zoom in to a certain level. I don't know what's wrong actually.
