I am using rate view for rating and I am checking if value of rate is less then 3 then it show have to enter text in the text view and I want to get value in view controller My code is like this

CustomTableviewcell.h

@interface NextTableview : UITableViewCell<RateViewDelegate,UITextViewDelegate>
{
    NSString *StatusValue;
    UILabel *lbl;
}

@property(nonatomic,strong) IBOutlet UILabel *staticlbl;
@property(nonatomic,strong) IBOutlet UITextView *commenttxtview;
@property(nonatomic,strong) IBOutlet UILabel *Kpiidlbl;

@property (weak, nonatomic) IBOutlet RateView *rateView;
@property (weak, nonatomic) IBOutlet UILabel *statusLabel;

@end

CustomTableviewcell.m

@synthesize rateView,staticlbl,statusLabel,commenttxtview,Kpiidlbl;
- (void)awakeFromNib {
    // Initialization code
}

    - (void)setSelected:(BOOL)selected animated:(BOOL)animated {
        [super setSelected:selected animated:animated];

        // Configure the view for the selected state

        commenttxtview.layer.borderWidth = 0.70f;
        commenttxtview.layer.borderColor = [[UIColor blackColor] CGColor];
        commenttxtview.delegate=self;


        UIToolbar* doneToolbar = [[UIToolbar alloc]initWithFrame:CGRectMake(0, 0, 320, 50)];
        doneToolbar.barStyle = UIBarStyleBlackTranslucent;
        doneToolbar.items = [NSArray arrayWithObjects:
                             [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil],
                             [[UIBarButtonItem alloc]initWithTitle:@"Done" style:UIBarButtonItemStyleDone target:self action:@selector(doneButtonClickedDismissKeyboard)],
                             nil];
        [doneToolbar sizeToFit];
        commenttxtview.inputAccessoryView = doneToolbar;

        lbl = [[UILabel alloc] initWithFrame:CGRectMake(10.0, 0.0,90.0, 34.0)];


        [lbl setText:@"Enter Text"];
        [lbl setFont:[UIFont systemFontOfSize:12]];
        [lbl setBackgroundColor:[UIColor clearColor]];
        [lbl setTextColor:[UIColor lightGrayColor]];
        commenttxtview.delegate = self;

        [commenttxtview addSubview:lbl];

        statusLabel.hidden=YES;

        commenttxtview.hidden=YES;

        // Do any additional setup after loading the view from its nib.
        self.rateView.notSelectedImage = [UIImage imageNamed:@"not_selected_star@2x.png"];
        self.rateView.halfSelectedImage = [UIImage imageNamed:@"half_selected_star@2x.png"];
        self.rateView.fullSelectedImage = [UIImage imageNamed:@"selected_star@2x.png"];
        self.rateView.rating = 0;
        self.rateView.editable = YES;
        self.rateView.maxRating = 5;
        self.rateView.delegate = self;

        Kpiidlbl.hidden=YES;
    }
    -(void)doneButtonClickedDismissKeyboard
    {
        [commenttxtview resignFirstResponder];
       // commenttxtview.hidden=YES;
    }

    - (void)textViewDidEndEditing:(UITextView *)theTextView
    {
        if (![commenttxtview hasText]) {
            lbl.hidden = NO;

        }
    }

    - (void) textViewDidChange:(UITextView *)textView
    {
        if(![commenttxtview hasText]) {
            lbl.hidden = NO;
        }
        else{
            lbl.hidden = YES;
        }
    }


    - (void)rateView:(RateView *)rateView ratingDidChange:(int)rating {
        self.statusLabel.text = [NSString stringWithFormat:@"%d", rating];
        NSLog(@"Rating value =%@",self.statusLabel.text);
        StatusValue=statusLabel.text;
        NSLog(@"Status Value String =%@",StatusValue);

        // Hear I am getting value of rating..in StatusValue..
        int status=[StatusValue intValue];
        if(status<=3)
        {
            commenttxtview.hidden=NO;
        }
        else{
            commenttxtview.hidden=YES;
        }

    }

How can I get label and textview value in viewcontroller and I want to set rate view value to rate view after reload table.

Answer 1

So write this in your CustomTableViewCell.h

@property(nonatomic,assign)NSInteger selectedRating;

everytime when the rating is updated in the Cell, you have to change the value of this variable.

In the viewController it depends on when you want to get the value of this cell. For example in this method:

    -(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
       CustomTableViewCell *yourCell = (CustomerTableViewCell*)[tableView cellForRowAtIndexPath:indexPath];
    NSLog(@"%lu",yourCell.selectedRating);
}

Let me know if this was helpful! Another way without a variable is to read the NSString in the statusLabel and change the string to a NSInteger variable...

If you are using your delegate...

Then implement the delegate RateViewDelegatein the viewController. The delegate is called in the class to which it is assigned...

Try this

You have to add the @property (nonatomic, weak) NSObject<RateViewDelegate>* delegate; to the header file of your CustomTableViewCell.h in the method

-(UITableViewCell) cellForRowAtIndexPath....

you have to assign the delegate like this

cell.delegate = self;

Now modify your cell delegate method to this

- (void)rateView:(RateView *)rateView ratingDidChange:(int)rating {
self.statusLabel.text = [NSString stringWithFormat:@"%d", rating];
NSLog(@"Rating value =%@",self.statusLabel.text);
StatusValue=statusLabel.text;
NSLog(@"Status Value String =%@",StatusValue);

// Hear I am getting value of rating..in StatusValue..
int status=[StatusValue intValue];
if(status<=3)
{
    commenttxtview.hidden=NO;
}
else{
    commenttxtview.hidden=YES;
}
if([self.delegate respondsToSelector:@selector(rateView:ratingDidChange:)]){
        [self.delegate rateView:rateView ratingDidChange:rating];
   }
}
