我已经在Objective-C中构建了一个XML解析器,并且消息objectForKey抛出了一个NSException但我不知道为什么。NSDictionary objectForKey抛出异常
aPicture = [[Picture alloc] init];
aPicture.pictureID = [[attributeDict objectForKey:@"id"] integerValue];
这里是例外的,我不明白的信息:
2010-08-09 21:27:32.223 rh[6375:207] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[Picture setPictureID:]: unrecognized selector sent to instance 0x592e0b0'
“长搜索”是“我发布我的问题后2分钟”? ;) – 2010-08-09 19:42:52
