Passing parameters from UITableViewCell to UITableView (Dynamic Content) - ios

Question

How might I pass my objects via parameters from my custom UITableViewCell class to my UITableView. Because I'm using Dynamic Prototype Cells, I can't assign my objects to the textviews within the cells. For this reason I need to pass my objects from class to class.
MainTableViewController.m
- (void)viewDidLoad
{
[super viewDidLoad];
NSURL *myURL = [[NSURL alloc]initWithString:#"http://domain.com/json2.php"];
NSData *myData = [[NSData alloc]initWithContentsOfURL:myURL];
NSError *error;
NSArray *jsonArray = [NSJSONSerialization JSONObjectWithData:myData options:NSJSONReadingMutableContainers error:&error];
if(!error)
{
for (NSDictionary * needs in jsonArray)
{
textNeedTitle.text = [needs objectForKey: #"needTitle"];
textNeedPoster.text = [needs objectForKey: #"needPoster"];
textNeedDescrip.text = [needs objectForKey: #"needDescrip"];
}
}
else
{
textNeedTitle.text = [NSString stringWithFormat:#"Error--%#",[error description]];
}
return cell;
// Uncomment the following line to preserve selection between presentations.
// self.clearsSelectionOnViewWillAppear = NO;
// Uncomment the following line to display an Edit button in the navigation bar for this view controller.
// self.navigationItem.rightBarButtonItem = self.editButtonItem;
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#pragma mark - Table view data source
- (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 3;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"Cell" forIndexPath:indexPath];
}
TestTableViewCell.h
#import <UIKit/UIKit.h>
#interface TestTableViewCell : UITableViewCell
#property (weak, nonatomic) IBOutlet UITextView *textNeedTitle;
#property (weak, nonatomic) IBOutlet UITextView *textNeedPoster;
#property (weak, nonatomic) IBOutlet UITextView *textNeedDescrip;
Each of the properties above are assigned via a Referencing Outlet to it's appropriate UITextView.

I'm not entirely sure what you're trying to do, but I noticed that in your UITableViewController you're getting a UITableViewCell instead of your custom class TestTableViewCell.
It should be like:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
TestTableViewCell *cell = (TestTableViewCell *) [tableView dequeueReusableCellWithIdentifier:#"Cell" forIndexPath:indexPath];
}
Make sure that:
* In the storyboard, the reuse identifier of the cells is "Cell" (or a more appropriate name...)
* The class for the prototype cells is TestTableViewCell
Then you should be able to access the properties of the cell, like cell.textNeedTitle.text = #"Something"
