How to get NSDictionary data into a UITableView

ios, iphone, nsdictionary, objective-c, uitableview

Solution

NSString *providerNameString = [self.providersDict objectForKey:@"provider"];
NSString *providerIdString = [self.providersDict objectForKey:@"object"];

You have initialized self.providersDict with keys 1, 2, 3. So you should Try to fetch `providerNameString` using those keys and not `@"provider"` same for `providerIdString`.

Try

NSString *key = [self.providersDict allKeys][indexPath.row];

NSString *providerNameString = self.providersDict[key];
NSString *providerIdString = key;
cell.textLabel.text  = providerNameString;
cell.detailTextLabel.text  = providerIdString;

And don't forget to call `[tableView reloadData];` once your `self.providersDict` is initialized.

As for a suggestion why dont you create a Model Class for `Provider` with id, name and other information. You can add each provider in an array and would make your life a lot easier.

Problem

I have 2 NSArrays that I'm trying to link together in an NSDictionary so that each providerName has a providerId associated with it. I expected the two arrays to be associated with each other using `self.providersDict = [NSDictionary dictionaryWithObjects:providerName forKeys:providerId];` and then the providerName to be displayed as the table cell title and the id as the table cell subtitle. At the moment I can't get the data displayed on the UITable or even log out the dictionary using: ``` for (id key in self.providersDict) { NSLog(@"key: %@, value: %@", key, [self.providersDict objectForKey:key]); } ``` declared in the .h: ``` NSArray *providerName; NSArray *providerId; @property (nonatomic, strong) NSDictionary *providersDict; ``` and in the viewDidLoad: ``` providerName = [NSArray arrayWithObjects:@"provider1", @"provider2", @"provider3", nil]; providerId = [NSArray arrayWithObjects:@"1", @"2", @"3", nil]; self.providersDict = [NSDictionary dictionaryWithObjects:providerName forKeys:providerId]; ``` the UITable methods: ``` -(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return [[self.providersDict allKeys] count]; } -(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *unifiedID = @"aCellID"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:unifiedID]; if (!cell) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:unifiedID]; } for (id key in self.providersDict) { NSLog(@"key: %@, value: %@", key, [self.providersDict objectForKey:key]); } NSString *providerNameString = [self.providersDict objectForKey:@"provider"]; NSString *providerIdString = [self.providersDict objectForKey:@"object"]; cell.textLabel.text = providerNameString; cell.detailTextLabel.text = providerIdString; return cell; } ``` thanks for the help.
