Question

I am adding download button in cell’s accessory view ..my code is

button = [UIButton buttonWithType:UIButtonTypeCustom];
UIImage *image = [UIImage imageNamed:@"download.png"];
[button setImage:image forState:UIControlStateNormal];
 //[button setTitle:@"Download" forState:UIControlStateNormal];
[button setFrame: CGRectMake( 110.0f, 3.0f, 80.0f, 30.0f)];
[button addTarget:self action:@selector(someAction) forControlEvents:UIControlEventTouchUpInside];
button.tag = indexPath.row;
cell.accessoryView = button;

And I want to pass file name from cell ‘s index path but this is not working It only takes first row…

- (void)someAction {

    [self.activityIndicator startAnimating];
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *file = [NSString stringWithFormat:@"/%@",[metaArray objectAtIndex:button.tag]]; 
    NSLog(@"%@", button.tag);   
    NSString *path = [NSString stringWithFormat:@"%@/Downloaded Data/%@",[paths objectAtIndex:0],file];

//  NSString *loadFileName = [NSString stringWithFormat:@"/%@/%@",Name,file];
    [self.restClient loadFile:file intoPath:path];
    NSLog(@"Downloaded:%@",file);
}

This crashing because of button.tag = indexpath.row
and if I don’t pass button.tag = indexpath.row it is passing only first row
please help

tag is an integer property. You are trying to print it as object in NSLog. You have to print it like this, NSLog(@"%d", button.tag);

Actually you have to assign individual download buttons to each cell.

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
UIImage *image = [UIImage imageNamed:@"download.png"];
[button setImage:image forState:UIControlStateNormal];
//[button setTitle:@"Download" forState:UIControlStateNormal];
[button setFrame: CGRectMake( 110.0f, 3.0f, 80.0f, 30.0f)];
[button addTarget:self action:@selector(someAction:) forControlEvents:UIControlEventTouchUpInside];
button.tag = indexPath.row;
cell.accessoryView = button;

And define your someAction method like this,

- (void)someAction:(id)sender {

    UIButton *button = (UIButton *)sender;
    NSLog(@"%d", button.tag); 
    [self.activityIndicator startAnimating];
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *file = [NSString stringWithFormat:@"/%@",[metaArray objectAtIndex:button.tag]];   
    NSString *path = [NSString stringWithFormat:@"%@/Downloaded Data/%@",[paths objectAtIndex:0], file];
   //NSString *loadFileName = [NSString stringWithFormat:@"/%@/%@",Name,file];
    [self.restClient loadFile:file intoPath:path];
    NSLog(@"Downloaded:%@", file);
}
