我有一个页面需要使用UITableView加载数据，有一个添加数据的选项，当点击添加时，我们显示两个文本框，3个UIPickerViews来加载项目，任务和子任务。下面是我要在UITableView中加载数据的代码，我无法找到出错的地方。请大家帮忙，我试着解决这个问题两天了。
- (void)viewDidLoad
{
[super viewDidLoad];
self.tableView.rowHeight = UITableViewAutomaticDimension;
self.tableView.estimatedRowHeight = 200.0;
[self loadprojects];
}
-(NSInteger) tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [projectNames count];
}
-(UITableViewCell*) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *identitifier = @"Cell";
TableViewCell * cell = [tableView
dequeueReusableCellWithIdentifier:identitifier
forIndexPath:indexPath];
if ([[[timesheetid objectAtIndex:indexPath.row] stringValue] isEqualToString:@"0"])
{
cell.lblProjects.text = [NSString stringWithFormat:@"%@",@"No Projects Filled"];
cell.lblTasks.text = [NSString stringWithFormat:@"%@",@"No Tasks Filled"];
cell.lblSubTasks.text = [NSString stringWithFormat:@"%@",@"No SubTasks Filled"];
cell.lblHours.text = [NSString stringWithFormat:@"%@",@"0 Hours Filled"];
cell.accessoryType = UITableViewCellAccessoryNone;
cell.selectionStyle = UITableViewCellSelectionStyleNone;
}
else if ([[leaves objectAtIndex:indexPath.row] isEqualToString:@"0"])
{
cell.lblProjects.text = [projectNames objectAtIndex:indexPath.row];
cell.lblTasks.text = [taskNames objectAtIndex:indexPath.row];
cell.lblSubTasks.text = [subtaskNames objectAtIndex:indexPath.row];
cell.lblHours.text = [[totalhours objectAtIndex:indexPath.row] stringValue];
NSLog(@"cell :%@",cell.lblHours.text);
NSLog(@"lblProjects :%@",cell.lblProjects.text);
}
else
{
cell.lblProjects.text = [leaves objectAtIndex:indexPath.row];
cell.lblTasks.text = [NSString stringWithFormat:@"%@",@"No Projects/Tasks on this Date"];
cell.lblSubTasks.text = [NSString stringWithFormat:@"%@",@"No Sub Tasks on this Date"];
cell.lblHours.text = [[totalhours objectAtIndex:indexPath.row] stringValue];
}
cell.editingAccessoryType = UITableViewCellAccessoryDetailDisclosureButton;
NSNumber *myProjectArrayString = [timesheetid objectAtIndex:indexPath.row];
cell.hdbrowcount = [NSString stringWithFormat:@"%@",myProjectArrayString];
return cell;
}
