来自Plist的数据在UITableView中的顺序不正确 [英] Data from Plist is Incorrectly Ordered in UITableView
问题描述
我有存储在plist中的数据,但是当我将其拉到UITableView时,由于某种原因,它会重新排序.这是我的表格视图数据源方法:
I have data that is stored in a plist but when I pull it to my UITableView it gets reordered for some reason. Here are my table view data source methods:
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return [self.lunch_Dinner count];
}
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section
{
return [[self.lunch_Dinner allKeys] objectAtIndex:section];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
NSString *typeOfEntree = [self tableView:tableView titleForHeaderInSection:section];
return [[self.lunch_Dinner valueForKey:typeOfEntree] count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"EntreeCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
// Configure the cell...
NSString *typeOfEntree = [self tableView:tableView titleForHeaderInSection:indexPath.section];
NSString *entree = [[self.lunch_Dinner valueForKey:typeOfEntree] objectAtIndex:indexPath.row];
cell.textLabel.text = entree;
return cell;
}
这是plist的顺序:
Here is the order of the plist:
- 开胃菜
- 汤
- 意大利面
- 比萨饼
- 特色菜
这是编译后的UITableView中的结果顺序:
And this is the resulting order in the UITableView after being compiled:
- 比萨饼
- 汤
- 开胃菜
- 意大利面
- 特色菜
任何帮助都会很棒! 预先感谢.
Any help would be great! Thanks in advance.
推荐答案
如果要将表存储在plist中,最好考虑以下结构:
If you want to store table in plist it is better to consider the following structure:
NSArray *sections = [NSArray arrayWithObjects:
[NSDictionary dictionaryWithObject:
[NSArray arrayWithObjects:row_1, row_2, ... , nil]
forKey:@"section name 1"],
[NSDictionary dictionaryWithObject:
[NSArray arrayWithObjects:row_1, row_2, ... , nil]
forKey:@"section name 2"],
...
[NSDictionary dictionaryWithObject:
[NSArray arrayWithObjects:row_1, row_2, ... , nil]
forKey:@"section name N"],
nil];
此代码表示形式易于复制为plist.如下例创建
This code representation is easy to reproduce as plist. Create it as in example below
此结构可以轻松用作UITableView数据源
This structure can be easily used as UITableView datasource
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return [self.datasource count];
}
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section
{
NSDictionary *dict = [self.datasource objectAtIndex:section];
return [dict.allKeys lastObject];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
NSDictionary *dict = [self.datasource objectAtIndex:section];
return [dict.allValues.lastObject count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSDictionary *dict = [self.datasource objectAtIndex:indexPath.section];
id cellPresenter = [dict.allValues.lastObject objectAtIndex:indexPath.row];
...
}
