带按钮的自定义表格视图单元格

Question

I am using storyboard. I have a table view with 1 Prototype cell, and have four rows in table view. Each cell has a label,image view and a button. Now I want to show different data on next View Controller say(DetailsVc), each time when button is pressed. Row1- Button click will open DetailsVC with some data. Row2- Button click will open DetailsVC with different data. and same process for remaining rows. Any suggestions.

@implementation DetailsVC

- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
EmpEngmntTableViewCell *emp;

 if((emp.viewGalleryBtn.tag = 1))
{
    NSLog(@"tag num for 1st row is %ld",(long)emp.viewGalleryBtn.tag);
    self.title = @"Team Building Session";
}
}

Answer 1

The best is to use a delegate pattern. I added an answer here , you can use it for example.

Here is an example enclosed:

Custom Cell .h Class:

@protocol DetailVCProtocol <NSObject>
-(void)loadDetailScreenWithIndex:(NSInteger)rowIndex;
@end

@property (nonatomic, retain) id<DetailVCProtocol> delegate;
@property (nonatomic, retain) IBOutlet UIButton *btn;

Then Synthesize it in .m file

Add this in m file :

-(IBAction)loadDetails:(id)sender
{
    // ..... blah blah
    [self.delegate loadDetailScreenWithIndex:btn.tag];
}

The viewcontroller that loads this cell:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
   // create cell here

   cell.btn.tag = indexPath.row;
   cell.delegate = self;
}

-(void)loadDetailScreenWithIndex:(NSInteger)rowIndex
{
  // Cretae DetailVC with parameter `rowIndex` to populate data
  [self presentViewController:detailVC animated:YES completion:nil];
}

Answer 2

In function - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

use this code

cell.btn.tag = indexPath.row;
[cell.btn addTarget:self action:@selector(btnTpd:) forControlEvents:UIControlEventTouchUpInside];

- (IBAction)btnTpd:(id)sender
{
UIButton *btn = (UIButton *)sender;
\\You can get which button is pressed by btn.tag
    \\Here call to next ViewController and pass data
}

In cellForRowAtIndexPath

 cell.optionsBtn.tag=indexPath.row;
 [cell.optionsBtn addTarget:self action:@selector(showMyOptionBtn:) forControlEvents:UIControlEventTouchUpInside];

-(void)showMyOptionBtn:(UIButton *)sender
{
  EventDetailViewController *EventDetail=[[EventDetailViewController alloc]init];
  EventDetail.buttonTag=sender.tag;
  [self.navigationController pushViewController:EventDetail animated:NO];

 }

In EventDetailViewController class

   if (self.buttonTag==1) {
     // your condation
   }
   else
   {
    //your condation
   }
