[英]Crash when loading an UITableView
我有一個 UITableView 從三個 NSMutableArrays 加載數據:
當加載少量項目時它工作正常,但是當加載項目(推特關注者)時它崩潰說我:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSMutableArray insertObject:atIndex:]: attempt to insert nil object at 2'
*** Call stack at first throw:
然后我去了它添加對象並刪除代碼的地方,現在奇怪的部分是錯誤仍然存在:我現在不知道在哪里找到:(提前謝謝!我將數據添加到數組的代碼(在 MGTwitterEngine方法):
- (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];
}
但是刪除它仍然會出錯:(
而當 arrays 是這樣的:

您尚未發布有問題的代碼,但異常只是說在您調用insertObject:atIndex:
時,您已將nil
作為 object 傳遞,這是不允許的。 如果要添加表示no value的值,則必須插入[NSNull null]
。
