I have a table view inside a View Controller. I can populate all my information inside the table view. However I am a bit lost for setting up the detail views. I believe each table cell needs a segue to a each detail view but not completely sure.
Here is my code. What am I missing to accomplish the segue from the table view to the detail views? Code:
.h
@interface DetailViewController : UIViewController <UITableViewDelegate,UITableViewDataSource>
{
IBOutlet UITableView *myTable;
NSMutableArray *contentArray;
}
@property (strong, nonatomic) IBOutlet UITableView *myTable;
.m
- (void)viewDidLoad
{
contentArray = [[NSMutableArray alloc]init];
[contentArray addObject:@"Espresso"];
[contentArray addObject:@"Latte"];
[contentArray addObject:@"Capicino"];
[super viewDidLoad];
// Do any additional setup after loading the view.
}
//Table Information
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [contentArray count];
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath*)indexPath
{
[tableView deselectRowAtIndexPath:indexPath animated:YES];
if([[contentArray objectAtIndex:indexPath.row]isEqualToString:@"EspressoViewController"])
{
EspressoViewController *espresso = [[EspressoViewController alloc]initWithNibName:@"EspressoViewController" bundle:nil];
[self.navigationController pushViewController:espresso animated:YES];
}
else if ([[contentArray objectAtIndex:indexPath.row] isEqualToString:@"Latte"])
{
LatteViewController *latte = [[LatteViewController alloc] initWithNibName:@"Latte" bundle:nil];
[self.navigationController pushViewController:latte animated:YES];
}
}
- (void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath
{
[self tableView:tableView didSelectRowAtIndexPath:indexPath];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath*)indexPath
{
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:@"CellIdentifier"];
}
NSString *cellValue = [contentArray objectAtIndex:indexPath.row];
cell.textLabel.text = cellValue;
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
cell.textLabel.font = [UIFont systemFontOfSize:16];
cell.detailTextLabel.text = @"Hot and ready";
UIImage *image = [UIImage imageNamed:@"coffeeButton.png"];
cell.imageView.image = image;
cell.textLabel.text = [contentArray objectAtIndex:indexPath.row];
return cell;
}
I think you made this a little too complicated. Don't worry, I do the same thing often.
First, by sending tableView:didSelectRowAtIndexPath:
from within tableView:accessoryButtonTappedForRowAtIndexPath:
there is no difference between the two methods. Tapping the cell, or it's accessory button performs the same action. If you don't need the accessory button to perform a different action than tapping the cell itself, remove it.
Second, if you're using a storyboard, you do not need to alloc/initWithNib for your view controllers. Instead, use a segue. If you do this through the storyboard, you also don't need to programmatically push viewControllers onto your navigationController
Build your storyboard first:
Then put the following code in your UITableViewController:
- (void)tableView:(UITableView *)tableView
didSelectRowAtIndexPath:(NSIndexPath*)indexPath {
//Build a segue string based on the selected cell
NSString *segueString = [NSString stringWithFormat:@"%@Segue",
[contentArray objectAtIndex:indexPath.row]];
//Since contentArray is an array of strings, we can use it to build a unique
//identifier for each segue.
//Perform a segue.
[self performSegueWithIdentifier:segueString
sender:[contentArray objectAtIndex:indexPath.row]];
}
How you implement the rest is up to you. You may want to implement prepareForSegue:sender:
in your UITableViewController and then use that method send information over to segue.destinationViewController
.
Note that I passed the string from your contentArray as the sender for the segue. You can pass whatever you like. The string that identifies the cell seems like the most logical information to pass, but the choice is up to you.
The code posted above should perform the navigation for you.
