2 UIViewController中的UITableView相互影响 [英] 2 UITableView in a UIViewController affecting each other
问题描述
我已经花了大约3个小时了，我终于把毛巾扔给所有人了。我的视图中有2个 UITableView ，其中一个是论坛，可以发表评论，什么不可以，第二个 UITableView 用来提人。我遇到的问题是，即使我只想更新其中一个表视图，两个 tableview计数都受到影响。
I've been going at this for about 3 hours now, and I'm finally throwing in the towel to y'all. I have 2 UITableViewin my view, one of which is a forum board to leave comments and what not, and the second UITableView is used to mention people. the issue I am having is that both tableview counts are being affected even if i only want to update just 1 of the tableviews.
我在 viewdidload
self.mentionTableView.delegate = self;
self.mentionTableView.dataSource = self;
self.mentionTableView.tag = 1;
self.forumTable.delegate = self;
self.forumTable.dataSource = self;
self.forumTable.tag = 2;
如果我实际上没有加载 feedArray 这是 forumTable 从中获取数据的地方，提及部分可以完美地工作。我发现如果 matchedNames.count < feedArray.count 一切正常，但如果 matchedNames.count > feedArray.count 它崩溃了，这是我得到的错误
and if i actually do not load feedArray which is where forumTable gets its data from, the mention portion works perfectly. I've figured out that if matchedNames.count<feedArray.count everything works fine, but if matchedNames.count>feedArray.count it crashes and this is the error i get
-[__NSCFArray objectAtIndex:]: index (1) beyond bounds (1)
这意味着我在 feedArray 中只有1个项目，而 matchedNames 有多个项目。
which means that i only have 1 item in feedArray and matchedNames has more than one.
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
我已经使用这些代码来尝试
i have used these codes to try to make it work and still nothing, ive even done combinations of them.
1）
if ([tableView isEqual: mentionTableView]){
NSLog(@"%@",matchedNames);
NSLog(@"%i",matchedNames.count);
return [matchedNames count];
} else if([tableView isEqual:forumTable]){
return [feedArray count];
}
2）
if (tableView == mentionTableView){
NSLog(@"%@",matchedNames);
NSLog(@"%i",matchedNames.count);
return [matchedNames count];
} else if(tableView == commentTable){
return [feedArray count];
}
3）
if (tableView.tag == 1){
NSLog(@"%@",matchedNames);
NSLog(@"%i",matchedNames.count);
return [matchedNames count];
} else if(tableView.tag == 2){
return [feedArray count];
}
我知道我不必做 else if ，但我只是想具体说明，以免发生此问题。
and I know I didnt have to do the else if but I was just trying to be specific to maybe avoid this issue.
这是我的 cellForRowAtIndexPath
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
if (tableView.tag == 1){
CGAffineTransform transform = CGAffineTransformMakeRotation(3.14);
static NSString *CellIdentifier = @"CellIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
cell.transform = transform;
cell.textLabel.text = [self.matchedNames objectAtIndex:indexPath.row];
return cell;
} else {
static NSString *CellIdentifier = @"commentCell";
commentsCustomCell *cell =(commentsCustomCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[commentsCustomCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
cell.selectionStyle = UITableViewCellSelectionStyleNone;
NSDictionary *feedPost = [feedArray objectAtIndex:indexPath.row];
NSString *checkIFempty = [feedPost objectForKey:@"isForum_empty"];
if (![checkIFempty isEqualToString:@"1"]) {
cell.noCommentsLabel.text = nil;
} else {
cell.noCommentsLabel.text = @"No Comments";
cell.forumComment = nil;
}
NSString *username =[feedPost objectForKey:@"Username"];
NSString *final_time =[feedPost objectForKey:@"final_time"];
NSString *userIDforPic =[feedPost objectForKey:@"UserID"];
finalComment = [feedPost objectForKey:@"comment"];
cell.forumComment.text = finalComment;
return cell;
}
}
如果我的问题令人困惑，我会抱歉，我还没睡36小时。感谢您看我的问题！
if my question is confusing i do apologize, I haven't slept 36 hours. thanks for looking at my question!
推荐答案
您真的真的应该考虑重构您的代码，并将这两个tableViews放在不同的viewControllers中。
You really really really should consider to refactor your code and separate this two tableViews in different viewControllers.
例如，您可以在主viewController中使用containerViews并将tableview放入容器视图控制器中。
You can, for example, use containerViews inside your main viewController and put the tableview in the container view controllers.
TableView委托使用了大量代码，并且将不同的tableViews设置到同一控制器将总是这样，从而弄乱了代码，并给程序带来了更多麻烦。
TableView delegates use a lot of code, and set different tableViews to the same controller will always end up like this, messing the code and giving more trouble than it should be.
