我有一个UITableView,它从三个NSMutableArrays中加载数据:
当加载一些项目时,它可以正常工作,但是当加载项目(推特粉丝)时它会崩溃说:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSMutableArray insertObject:atIndex:]: attempt to insert nil object at 2'
*** Call stack at first throw:
然后我去了添加对象的地方并删除了代码,现在奇怪的部分是错误仍然存在! 我不知道现在在哪里找到:(提前谢谢! 我在数组中添加数据的代码(在MGTwitterEngine方法上):
- (void)userInfoReceived:(NSArray *)userInfo forRequest:(NSString *)connectionIdentifier {
followers = [[NSMutableArray alloc] init];
followersname = [[NSMutableArray alloc] init];
followerspic = [[NSMutableArray alloc] init];
for(NSDictionary *d in userInfo) {
NSLog(@"See dictionary: %@", d);
NSString *user = [d objectForKey:@"screen_name"];
NSString *realname = [d objectForKey:@"name"];
NSString *pic = [d objectForKey:@"profile_image_url"];
[followers addObject:user];
[followersname addObject:user];
[followerspic addObject:user];
NSLog(@"%@", followers);
NSLog(@"%@", followersname);
NSLog(@"%@", followerspic);
}
[DSBezelActivityView removeViewAnimated:YES];
[self.tableView reloadData];
}
但删除它仍然会出错:(
当阵列是这样的时候:

答案 0 :(得分:4)
您尚未发布相关代码,但例外情况只是说在您对insertObject:atIndex:
的调用中,您已将nil
作为对象传递,这是不允许的。如果您想添加表示无值的值,则必须改为插入[NSNull null]
。
