I am trying to populate a UITableView with information from a plist file. I don't know where I am going wrong. Please check the images for my requirement and the code above to find where I am wrong
I need to populate above image in UITableView in such way that array a, b, c should come in the section field. Its coming right in below. But I am unable to populate data
please check where I am wrong.
.
.
#synthesize mySections //array
#synthesize myData //dictionary
- (void)viewDidLoad
{
[super viewDidLoad];
//LOADING THE PLIST FILE
//Create a string representing the file path
NSString *plistPath = [bundle pathForResource:#"yourFilename" ofType:#"plist"];
//Load the file in a dictionnary
NSDictionary *dict = [[NSDictionary alloc] initWithContentsOfFile:plistPath];
self.myData = dict;
//SORTING THE DICTIONARY
NSArray *dicoArray = [[self.myData allKeys] sortedArrayUsingComparator:^(id firstObject, id secondObject) {
return [((NSString *)firstObject) compare:((NSString *)secondObject) options: NSCaseInsensitiveSearch];
}];
self.mySections = dicoArray;
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
//Return the number of sections.
return [self.mySections count];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of rows in the section.
NSString *key = [self.mySections objectAtIndex:section];
NSArray *dataInSection = [self.myData objectForKey:key];
return [dataInSection count];
}
-(NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
NSString *key = [self.mySections objectAtIndex:section];
return [NSString stringWithFormat:#"%#", key];
}
-(NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView {
return self.mySections;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:CellIdentifier] autorelease];
}
// Configure the cell...
NSUInteger section = [indexPath section];
NSUInteger row = [indexPath row];
NSString *key = [self.mySections objectAtIndex:section];
NSDictionary *Dic=self.myData;
NSArray *dataForSection = [self.myData objectForKey:Dic.allKeys];
cell.textLabel.text = [dataForSection objectAtIndex:row];
return cell;
}
some code of plist is:-
<plist version="1.0">
<dict>
<key>a</key>
<array>
<dict>
<key>Beta_Carot_(µg)</key>
<string>0.06</string>
<key>Cholestrl_(mg)</key>
<string>215</string>
<key>fdgdfg</key>
<string>dfgdfg</string>
</dict>
</array>
<key>b</key>
<array>
<dict>
<key>Alpha_Carot_(µg)</key>
<string>0</string>
<key>gdfg</key>
<string>fdgdfg</string>
</dict>
</array>
<key>c</key>
<array>
<dict>
<key>Alpha_Carot_(µg)</key>
<string>0</string>
<key>Ash_(g)</key>
<string>0</string>
<key>Beta_Caro</key>
<string>193</string>
<key>Choline_Tot_ (mg)</key>
<string>22.3</string>
<key>dgd</key>
<string>dgdf</string>
</dict>
</array>
</dict>
</plist>

Answer 1

You need to get to count the number of elements in the right data structure when determining the number of rows in each section. So in - tableView: numberOfRowsInSection: you need to have
NSArray *dataInSection = [[self.myData objectForKey:key] objectAtIndex:0];
return [dataInSection count];
There is also a problem in - tableView: cellForRowAtIndexPath:. You create the correct key to get the data for your section in *key but then you instead use Dic.allKeys as a key to retrieve data from self.myData. So you are sending in a whole array as the key when you set *dataForSection.
So change these lines:
NSString *key = [self.mySections objectAtIndex:section];
NSDictionary *Dic=self.myData;
NSArray *dataForSection = [self.myData objectForKey:Dic.allKeys];
cell.textLabel.text = [dataForSection objectAtIndex:row];
To:
NSString *key = [self.mySections objectAtIndex:section];
NSDictionary *dataForSection = [[self.myData objectForKey:key] objectAtIndex:0];
cell.textLabel.text = [[dataForSection allKeys] objectAtIndex:row];

I think you're not drilling far enough down your data hierarchy. In numberOfRowsInSection: you're getting the value for the key in the root level dictionary: Looks like this is always an NSArray with only a single item: A dictionary. You probably want something like
...
NSDictionary *dataInSection = [[self.myData objectForKey:key] objectAtIndex:0];
return [dataInSection count];
...

According to me you are doing some mistake in table fetch data from plist
plz try this
- (void)viewDidLoad
{
[super viewDidLoad];
//LOADING THE PLIST FILE
//Create a string representing the file path
NSString *plistPath = [bundle pathForResource:#"yourFilename" ofType:#"plist"];
NSMutableArray *listArray=[NSMutableArray arrayWithContentsOfFile:[[NSBundle mainBundle] pathForResource:#"yourFilename" ofType:#"plist"]];
self.sections = [[NSMutableDictionary alloc] init];
}
Then set your data according to your need from plist data come as an array, then dict may be help this information you..
