先判断presentedViewController为空时，再presentModalViewController
if (rootviewController.presentedViewController ==
nil)
{
[rootviewController
presentModalViewController:imagePicker
animated:YES];
}
if (rootviewController.presentedViewController ==
nil)
{
[rootviewController
presentModalViewController:imagePicker
animated:YES];
}
