委托按钮单击在表格单元格中不起作用

Question

I am using Delegate method to access my table view's cell's information for button click methods.my table view cells are customised. i have design the cells in a separate xib file and also declare a tableViewCell type class for the cell.and given that class to the cell which i have designed. I am loading different cell designs according to a date and some other conditions in the same table view. But the problem is when i click a button inside my cell, it is not working. I have put a break point to the place where the code is, but it is not going to the breakpoint.

Here is the steps i followed. It was worked fine when i designed my table cell inside the prototype cell using storyboards . I did the same thing using xib, but i don't know what is the wrong.

this is my customised cell's .h class which i declare the delegate #import

@class CellForComingDates;

@protocol ComingDateRowDelegate <NSObject>

-(void)DeleteButtonAction_new:(CellForComingDates*)cell;


@end


@interface CellForComingDates : UITableViewCell

@property (strong, nonatomic) IBOutlet UIImageView *cellImage;
@property (strong, nonatomic) IBOutlet UILabel *personName;
@property (strong, nonatomic) IBOutlet UILabel *appoinmentTime;
@property (strong, nonatomic) IBOutlet UILabel *appoinmentDate;
@property (strong,nonatomic) NSString* appoinmentstartTime;
@property (strong,nonatomic) NSString* appoinmentendTime;
@property (strong,nonatomic) NSString* appoinmentID;
@property (strong,nonatomic) NSString* USER;

@property (weak) id<ComingDateRowDelegate> comingDateDel;


@end

Here is the .m class which my IBAction method is included. and i have connect the IBaction to the button correctly

- (IBAction)DeleteButton:(id)sender {
[self.comingDateDel DeleteButtonAction_new:self];
}

Then, inside the tableView class, i have implemented the click method

-(void)DeleteButtonAction_new:(CellForComingDates*)cell{
     AppoinmentID = cell.appoinmentID;
   UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Delete Appoinment"
                                                message:@"click ok to delete"
                                               delegate:self
                                      cancelButtonTitle:@"OK"
                                      otherButtonTitles:@"Cancel",nil];
alert.tag = kAlertViewTwo;
[alert show];
}

but when i click the button it is not responding... can someone tell me what happened here ?

thank you

Answer 1

I think you forgot [cell setComingDateDel:self];

Add this calling in cellForRowAtIndexPath .

UPDATE:

Try to add [cell setComingDateDel:self]; right before you do return .

Answer 2

Inside cellForRowAtIndexPath delegate use this code:

[cell.deleteButton setTag:indexPath.row];
[cell.deleteButton addTarget:self 
                       action:@selector(deletebuttonClicked:)
            forControlEvents:UIControlEventTouchDown];

then

-(void)deletebuttonClicked:(UIButton*)button {

    long int selectedIndex=(long int)[button tag];
 }

Answer 3

add button in CellForComingDates class and connect IBAction to the button, then

- (IBAction)DeleteButton:(id)sender {
    [self.comingDateDel DeleteButtonAction_new:self];
}

then after write your delete method in your .m which have tableview.

Answer 4

Small change in the code you have written for cellForRowAtIndexPath

>>[cell setComingDateDel:self];  // Move this line to the if block

 if (! cell) 
 {
   NSArray *parts = [[NSBundle mainBundle] loadNibNamed:@"comingDayCell" owner:nil options:nil];
   cell = [parts objectAtIndex:0];
   [cell setComingDateDel:self]; // Now this is proper
  }

Answer 5

Check below function by debugging:

- (IBAction)DeleteButton:(id)sender {
if ([self.comingDateDel respondsToSelector:@selector(DeleteButtonAction_new:)]) {
    [self.comingDateDel DeleteButtonAction_new:self];
}
}
