我有实现 reverseGeocoder 的方法

- (void)reversing { 
 geoCoder=[[MKReverseGeocoder alloc] initWithCoordinate:locManager.location.coordinate];
 geoCoder.delegate=self;
 [geoCoder start]; 
}

我记得用另一种方法倒车：

[self performSelector:@selector(reversing) withObject:nil afterDelay:10];

我收到

Program received signal:  “EXC_BAD_ACCESS”.

有人能帮我吗？:D

看起来您正在释放地理编码器或其委托，这会导致 BAD_ACCESS。很有可能您已经在错误处理程序中释放了它，或者在释放调用对象时可能通过 dealloc 释放它。

我对类似问题的回答：

我最近遇到并解决了这个问题。就我而言，当 Apple Map 找不到任何查询结果时，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”。

发现这一点很费劲，MapKit 需要一个更好的错误处理系统。

mhmmm 现在 performSelector 可以工作 mhmm 10-12 次，然后退出
