Passing data from dynamic tableview back to static tableview - ios

Question

Please help i have been struggling passing back the data. I have 2 tableViews. 1st tableview=static table=RootVC. 2nd tableview=dynamic table=FirstVC. in RootVC i have a cell with two labels, "repeatLabel" and "repeatDetail" with a disclosure indicator. When i click on the cell it display the next table which is FirstVC, FistVC is populated with weekdays. after selection of my choice, i want the selected days to be passed back into RootVC in "repeatDetail" and when i go back still be able to see previously selected data.
My RootVC looks like this:
#import "RepeatViewController.h"
#interface SettingsViewController : UITableViewController
#property (strong, nonatomic) IBOutlet UILabel *repeatDetail;
#property (strong, nonatomic) IBOutlet UILabel *repeatLabel;
#property (strong,nonatomic) NSString *getRepeatDetail;
#property (nonatomic, strong) NSMutableArray *selectedDaysArray;
#end
in my RootVC.m
#import "SettingsViewController.h"
#interface SettingsViewController ()
#end
#implementation SettingsViewController
#synthesize repeatLabel,repeatDetail;
#synthesize getRepeatLabel;
#synthesize selectedDaysArray;
- (void)viewDidLoad
{
[super viewDidLoad];
repeatLabel.text = #"Repeat";
repeatDetail.text = getRepeatLabel;
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
RepeatViewController *destinationController = segue.destinationViewController;
if( [destinationController isKindOfClass:[RepeatViewController class]] )
{
//You can reuse your selectedDays arrays
destinationController.selectedDays = self.selectedDaysArray;
[(RepeatViewController *)destinationController setCompletionBlock:^(NSArray *retDaysArray) // <- make this change
{
// Save your changes
self.selectedDaysArray = [NSMutableArray arrayWithArray: retDaysArray]; // <- make this change
NSLog(#"retDaysArray: %#", self.selectedDaysArray); //<- Add this debug line
}];
}
}
#end
My 1stVC.h
#import "SettingsViewController.h"
typedef void(^WeekdayCompletionBlock)(NSArray *retDaysArray);
#interface RepeatViewController : UITableViewController <UITableViewDataSource,UITableViewDelegate>
#property (nonatomic,strong) NSMutableArray *selectedDays;
#property (nonatomic, copy) NSArray *completionBlock;
#property (copy) WeekdayCompletionBlock returnBlock;
//#property (strong, nonatomic) IBOutlet UIBarButtonItem *saveButton;
-(IBAction)save:(id)sender;
#end
my 1stVC.m
#import "RepeatViewController.h"
#interface RepeatViewController ()
#end

#synthesize selectedDays= _selectedDays;

Answer 1

When you work with static cells you have to bind the control you are using directly, there's no need.
So what I can suggest you is the following:
Bind your controls with some specific identifier, like labelFieldRow{rowid} example: labelFieldRow1.
So on prepare for segue, just check what's the selected row and pass the data you want to the destination controller.
Probably not the best, but it should work.

Answer 2

You have to pass data (selected by user before) from your RootVC to FirstVC. To do that in your RootVC add property to keep the selected data;
#property (nonatomic, strong) NSMutableArray *selectedDaysArray;
In prepareForSegue method you have to pass that array to let the table view know what needs to be selected:
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
UIViewController *destinationController = segue.destinationViewController;
if( [destinationController isKindOfClass:[RepeatViewController class]] )
{
//You can reuse your selectedDays arrays
((RepeatViewController*)destinationController).selectedDays = self.selectedDaysArray;
[(RepeatViewController *)destinationController setReturnBlock:^(NSArray *retDaysArray) // <- make this change
{
// Save your changes
self.selectedDaysArray = [NSMutableArray arrayWithArray: retDaysArray]; // <- make this change
NSLog(#"DATA: %#", self.selectedDaysArray) //<- Add this debug line
}];
}
}
Remove this line from viewDidLoad you don't want to allocate it every time now you just pass it from rootVC
_selectedDays = [[NSMutableArray alloc] init];
And in cellForRowInIndexPath replace this line:
cell.textLabel.text = [completionBlock objectAtIndex:indexPath.row];
with this code:
NSString *day = completionBlock[indexPath.row];
cell.textLabel.text = day;
if ([self.selectedDays containsObject:day])
cell.accessoryType = UITableViewCellAccessoryCheckmark;
else
cell.accessoryType = UITableViewCellAccessoryNone;
And change didSelectRowAtIndexPath: to
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
if (!self.selectedDays)
self.selectedDays = [[NSMutableArray alloc] init];
if (cell.accessoryType == UITableViewCellAccessoryCheckmark)
{
cell.accessoryType = UITableViewCellAccessoryNone;
//remove data from array
[self.selectedDays removeObject:[completionBlock objectAtIndex:indexPath.row]];
}
else
{
cell.accessoryType = UITableViewCellAccessoryCheckmark;
//add data to array
[self.selectedDays addObject:[completionBlock objectAtIndex:indexPath.row]];
}
[tableView deselectRowAtIndexPath:indexPath animated:YES];
}
Hope this help.
