iOS Question

Pass multiple parameter using cell button action

NOTE: i don't need any suggestion regarding sending data using didselect delegate of UITableview

myButton.h

#import <UIKit/UIKit.h>
@interface myButton : UIButton
{
id userData;
}

@property (strong,nonatomic) NSString* data1;

@end


myButton.m

#import "myButton.h"

@implementation myButton

/*
// Only override drawRect: if you perform custom drawing.
// An empty implementation adversely affects performance during animation.
- (void)drawRect:(CGRect)rect {
// Drawing code
}
*/

@end


My custom cell for testCollectionViewCell.h

#import "myButton.h"
@interface testCollectionViewCell : UICollectionViewCell
@property (nonatomic,weak) IBOutlet myButton *serviceFav;


My custom cell for testCollectionViewCell.m

#import "testCollectionViewCell.h"
#import <QuartzCore/QuartzCore.h>

@implementation testCollectionViewCell
@synthesize serviceFav;
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
// Initialization code

//self.serviceFav=[myButton buttonWithType:UIButtonTypeCustom];

}
return self;
}


// Only override drawRect: if you perform custom drawing.
// An empty implementation adversely affects performance during animation.
- (void)drawRect:(CGRect)rect
{



}

@end


And here is my code for the collection view delegate

- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
testCollectionViewCell *cell = [testCollectionViewCell dequeueReusableCellWithReuseIdentifier:@"testCollectionViewCell" forIndexPath:indexPath];
cellData = [self.collectionData objectAtIndex:[indexPath row]];

cell.serviceFav.data1 = @"data1"; **//shows error here and kills**

[cell.serviceFav addTarget:self action:@selector(touchUpHandler:) forControlEvents:UIControlEventTouchUpInside];


return cell;
}


//------ THIS IS NOT CALLED ----I WANT TO CALL IT

-(void)touchUpHandler:(myButton*)sender
{

UIButton *button = (myButton *)sender; //instance of UIButton
NSLog(@"Data 1 = %@",sender.data1);
}

Answer

I just made a sample with the same process as in the Question and it worked.

Took a custom Button Class

MyButton.h

#import <UIKit/UIKit.h>

@interface MyButton : UIButton

@property (strong,nonatomic) NSString* data1;
@property (strong,nonatomic) NSString* data2;

@end

MyButton.m

#import "MyButton.h"

@implementation MyButton

@end

Make an IBOutlet to your CustomCell Class

CustomTableViewCell.h

#import <UIKit/UIKit.h>
#import "MyButton.h"

@interface CustomTableViewCell : UITableViewCell
@property (weak, nonatomic) IBOutlet MyButton *btnLike;

@end

ViewController.m

#import "ViewController.h"
#import "CustomTableViewCell.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
}

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    return 5;
}

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    CustomTableViewCell* cell = (CustomTableViewCell*)[tableView dequeueReusableCellWithIdentifier:@"CustomTableViewCell"];

    cell.btnLike.data1 = @"data1";
    cell.btnLike.data2 = @"data2";

    [cell.btnLike addTarget:self action:@selector(touchUpHandler:) forControlEvents:UIControlEventTouchUpInside];

    return cell;

}

- (void) touchUpHandler:(MyButton *)sender {

    NSLog(@"Data 1 = %@",sender.data1);
    NSLog(@"Data 2 = %@",sender.data2);

}
@end

On clicking on the button in the cell, it goes to the selector method touchUpHandler and prints on console

2016-10-12 23:14:39.034 tabletest[28414:671128] Data 1 = data1
2016-10-12 23:14:39.035 tabletest[28414:671128] Data 2 = data2
