我有这个NSArray,每个项目返回一个POIndex和PONumber,我将数组的每个项目放在另一个数组中,另一个数组返回如下:
POIndex
PONumber
POIndex
PONumber
这是我的代码:
- (void)GetRequest
{
NSArray *tableData = [dataSource.areaData GetPurchaseOrderItems:[NSString stringWithFormat:@"%@%@",areaPickerSelectionString,unitPickerSelectionString]];
if(!self.objects){
self.objects = [[NSMutableArray alloc]init];
}
for(int i = 0; i < [tableData count]; i++){
[self.objects addObjectsFromArray:[tableData objectAtIndex:i]];
}
[self.tableView reloadData];
}
以下是tableData返回的屏幕截图:
我要做的是将PONumber作为键,POIndex作为显示值,我该怎么做?
我尝试了以下内容:
NSMutableDictionary *subDict=[[NSMutableDictionary alloc]init];
for (NSDictionary *dict in tableData) {
[subDict setValue:[dict objectForKey:@"POIndex"] forKey:[dict objectForKey:@"PONumber"]];
[self.objects addObject:subDict];
}
但显示如下:
{
{
{
{
以下是显示它的内容:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"Cell" forIndexPath:indexPath];
NSString *object = self.objects[indexPath.row];
cell.textLabel.text = [object description];
return cell;
}
答案 0 :(得分:1)
您的tableData数组在每个索引处包含NSDictionary。因此,您可以在cellForRowIndexPath方法中使用相同的数组,如下所示,
@property(nonatomic, retain) NSArray * tableData;
- (void)GetRequest
{
self.tableData = [dataSource.areaData GetPurchaseOrderItems:[NSString stringWithFormat:@"%@%@",areaPickerSelectionString,unitPickerSelectionString]];
[self.yourTableView reloadData];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"Cell" forIndexPath:indexPath];
NSString *strPOIndex = [self.tableData[indexPath.row] valueForKey:@"POIndex"];
cell.textLabel.text = strPOIndex;
return cell;
}
