如何从数组中过滤多个选定的值，并将其从uibutton加载到其他uitableview [英] How to filter the multiple selected values from an array and load it to other uitableview from a uibutton
问题描述
我在UiViewController中有2个UiTableviews。我的确切要求是从tableview1获取所选值并通过点击添加按钮加载到tableview2。
I have 2 UiTableviews in a UiViewController. My exact requirement is to get the selected values from tableview1 and loaded to the tableview2 by tapping the Add Button.
我完成了当前
1.已加载JSON响应tableview1（此时加载来自文件路径的响应）并打印到自定义nib单元格
2.我可以将所选值输入到响应中，如下所示
下一页
3.我想从所选值中将该值打印到* cell2。请详细说明接下来的步骤。
I done Following at the moment 1. loaded JSON Responses to tableview1 (loaded the responses from a filepath at the moment) and printed to a custom nib cell 2. I can get the selected values to a response as follows Next 3. I want to print that values to *cell2 from the selected values. Please explain the next steps in details.
这是UI

我添加了所有必需的代码来查看它。因为我是iOS Dev的新手。请一步一步地写一个代码/说明，以节省一些时间:)。
I Added All the required codes to have a look at it. Since I am relatively new to iOS Dev. Please Write a codes / instructions step by step clearly to save some time :).
**请注意：目前我将相同的tableview1数据加载到tableview2 * cell2但是我想在这里加载所选的值（Multiple Selection）。从tableview1 loadedPSAData数组加载到表视图中通过点击添加按钮。最后抱歉我的英语不好;）**
**Please Note : At the moment I loaded the same tableview1 data to tableview2 *cell2 But I want here to load the selected values(Multiple Selection). from tableview1 loadedPSAData Array to load in table view to by tapping an Add Button. Finally sorry for my poor English ;) **
推荐答案
假设这2个是你的桌面插座。
Suppose these 2 are your table outlet.
__weak IBOutlet UITableView * myTable1;
__weak IBOutlet UITableView * myTable2;
您在viewDidLoad中设置代理和数据源如下所示
You set the Delegate and Data Source like below in your viewDidLoad
myTable1.delegate=self;
myTable1.dataSource=self;
myTable2.delegate=self;
myTable2.dataSource=self;
现在这些是2个数组
array1 ==> Which contain All Data
arraySelectedValues ==> Which contain you selected data
所以你使用下面这个
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
if(self.myTable1 == tableView)
{
return [array1 count];
} else {
return [arraySelectedValues count];
}
}
当我查看您的代码时，您的问题可能出在CellForRow。当存在相同的CellIdentifier时，为什么要创建2个单独的单元格。您只需要更改数据。
As I review your Code, Your problem may be in CellForRow. Why to create 2 separate cells, when there is same CellIdentifier. You just need to change the Data.
你应创建2个单元 当两个Tableview使用 Diff-Diff tableviewcells时。在你的情况下你是使用相同的单元格。
You should create 2 cells only When Both Tableview are using Diff-Diff tableviewcells. In your case you are using same cell.
尝试修改这样的代码
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *cellIdentifier=@"PSATableViewCell";
PSATableViewCell *cell=[tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell==nil) {
cell=[[PSATableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier: cellIdentifier];
}
if(tableView == myTable1)
{
[cell loadWithData:[array1 objectAtIndex:[indexPath row]]];
}
else if(tableView == myTable2)
{
[cell loadWithData:[arraySelectedValues objectAtIndex:[indexPath row]]];
}
return cell;
}
didSelectRowAtIndexPath 应如下所示：
- (void)tableView:(UITableView *)tableView
didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
if(tableView == myTable1)
{
// Your code for highlighting
} else {
// This will be you myTable2 did select click.
}
}
正好当你想刷新时记录，您应该调用ReloadData方法对于各自的表格视图。
希望您了解如何在单个ViewController中的2个Tableview中加载数据。
Hope you understand how you load the data in 2 Tableviews in Single ViewController.
