Error when passing data between views
- by Kristoffer Bilek
I'm using a plist (array of dictionaries) to populate a tableview. Now, when a cell i pressed, I want to pass the reprecented dictionary to the detail view with a segue. It's working properly to fill the tableview, but how do I send the same value to the detail view? This is my try:
#import "WinesViewController.h"
#import "WineObject.h"
#import "WineCell.h"
#import "WinesDetailViewController.h"
@interface WinesViewController ()
@end
@implementation WinesViewController
- (id)initWithStyle:(UITableViewStyle)style
{
self = [super initWithStyle:style];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
}
- (void)viewDidUnload
{
[super viewDidUnload];
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
#pragma mark - Table view data source
- (void)viewWillAppear:(BOOL)animated {
wine = [[WineObject alloc] initWithLibraryName:@"Wine"];
self.title = @"Vinene";
[self.tableView deselectRowAtIndexPath:[self.tableView indexPathForSelectedRow] animated:YES];
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
// Return the number of sections.
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of rows in the section.
return [wine libraryCount];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"wineCell";
WineCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
// Configure the cell...
cell.nameLabel.text = [[wine libraryItemAtIndex:indexPath.row] valueForKey:@"Name"];
cell.districtLabel.text = [[wine libraryItemAtIndex:indexPath.row] valueForKey:@"District"];
cell.countryLabel.text = [[wine libraryItemAtIndex:indexPath.row] valueForKey:@"Country"];
cell.bottleImageView.image = [UIImage imageNamed:[[wine libraryItemAtIndex:indexPath.row] valueForKey:@"Image"]];
cell.flagImageView.image = [UIImage imageNamed:[[wine libraryItemAtIndex:indexPath.row] valueForKey:@"Flag"]];
cell.fyldeImageView.image = [UIImage imageNamed:[[wine libraryItemAtIndex:indexPath.row] valueForKey:@"Fylde"]];
cell.friskhetImageView.image = [UIImage imageNamed:[[wine libraryItemAtIndex:indexPath.row] valueForKey:@"Friskhet"]];
cell.garvesyreImageView.image = [UIImage imageNamed:[[wine libraryItemAtIndex:indexPath.row] valueForKey:@"Garvesyre"]];
return cell;
}
#pragma mark - Table view delegate
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([[segue identifier] isEqualToString:@"DetailSegue"]) {
NSIndexPath *selectedRowIndex = [self.tableView indexPathForSelectedRow];
WinesDetailViewController *winesdetailViewController = [segue destinationViewController];
//Here comes the error line:
winesdetailViewController.winedetailName = [wine objectAtIndex:indexPath.row] valueForKey:@"Name"];
}
}
I get one error for:
winesdetailViewController.winedetailName = [wine objectAtIndex:indexPath.row] valueForKey:@"Name"];
Use of undeclaired identifier: indexPath. did you mean NSIndexPath? I think I've missed something important here..
