Plist到UITableView

Question

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..
