我的方法是实现reverseGeocoder
- (void)reversing {
geoCoder=[[MKReverseGeocoder alloc] initWithCoordinate:locManager.location.coordinate];
geoCoder.delegate=self;
[geoCoder start];
}
我记得用另一种方法逆转：
[self performSelector:@selector(reversing) withObject:nil afterDelay:10];
我收到了

Program received signal: “EXC_BAD_ACCESS”.
有人能帮助我吗？ ：d

看起来您正在释放地理编码器或其委托，这会导致BAD_ACCESS。你已经在你的错误处理程序中释放它，或者当你的调用对象被释放时，可能通过dealloc很好。

My answer to a similar question:
我最近遇到并解决了这个问题。在我的情况下，当Apple Map找不到查询的任何结果时，它有时会抛出这个“MKErrorDomain = 4”错误。所以我最终只是将其视为“未找到结果”。
找到这个是很费劲的，MapKit需要一个更好的错误处理系统。

mhmmm现在performSelector已经工作了10到12次mhmm，然后用这个退出
