ios - 如何解决 "undeclared selector ' forwardGeocoderDidFail :withErrorMessage"warning?

Question

如何解决这个警告？

警告是“未声明的选择器‘forwardGeocoderDidFail:withErrorMessage:’”。为什么会收到此警告，我该如何解决？

这是我的代码:

if (!handeledByBlocks && self.delegate) {
    if (!parseError && parser.statusCode == G_GEO_SUCCESS)
    {
        [self.delegate forwardGeocodingDidSucceed:self withResults:parser.results];
    }
    else if ([self.delegate respondsToSelector:@selector(forwardGeocoderDidFail:withErrorMessage:)])
    {
        [self.delegate forwardGeocodingDidFail:self withErrorCode:parser.statusCode andErrorMessage:[parseError localizedDescription]];
    }        
}

Answer 1

替换

[self.delegate respondsToSelector:@selector(forwardGeocoderDidFail:withErrorMessage:)]

与

[self.delegate respondsToSelector:@selector(forwardGeocodingDidFail:withErrorCode:andErrorMessage:)]
