UITableView con più sezioni

Question

Voglio rendere tableView con più sezioni ma non voglio usare il dizionario ho due array voglio che il primo array debba essere caricato nella prima sezione e il secondo nella seconda sezione.

Ho arrayOne con 3 elementi e arrayTwo con 4 elementi, quindi come aggiungerli e mostrarli in sezioni.

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section 
{ 
    if(section == 0) 
     return resultArray.count; 
    else 
     return resultArray.count; 
} 

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { 
    return 2; 
} 


- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section 
{ 
    NSLog(@"Number of Sections"); 
    if(section == 0) 
     return @"Section 1"; 
    if(section == 1) 
     return @"Section 2"; 
} 

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { 
    NSLog(@"Table Cell Data"); 
    static NSString *CellIdentifier = @"Cell"; 
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; 
    if (cell == nil) { 
     cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier]; 
    } 

    appDelegate = (MultipleDetailViewsWithNavigatorAppDelegate *)[[UIApplication sharedApplication] delegate]; 

    if (indexPath.section==0) {  
     appDelegate = (MultipleDetailViewsWithNavigatorAppDelegate *)[[UIApplication sharedApplication] delegate]; 
     ObjectData *theCellData = [resultArray objectAtIndex:indexPath.row]; 
     NSString *cellValue =theCellData.category; 
     NSLog(@"Cell Values %@",cellValue); 
     cell.textLabel.text = cellValue; 
     return cell; 
    } 
    else { 
     ObjectData *theCellData = [resultArray objectAtIndex:indexPath.row]; 
     NSString *cellValue =theCellData.category; 
     cell.textLabel.text = cellValue; 
     return cell;  
    } 
} 

Answer 1

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { 
     return 2 ; 
} 

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { 
     if (section==0) 
     { 
      return [array1 count]; 
     } 
     else{ 
      return [array2 count]; 
     } 
} 

- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section { 
     if(section == 0) 
      return @"Section 1"; 
     else 
      return @"Section 2"; 
} 


- (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]; 
     } 

if (indexPath.section==0) { 
    ObjectData *theCellData = [array1 objectAtIndex:indexPath.row]; 
    NSString *cellValue =theCellData.category; 
    cell.textLabel.text = cellValue; 
} 
else { 
    ObjectData *theCellData = [array2 objectAtIndex:indexPath.row]; 
    NSString *cellValue =theCellData.category; 
    cell.textLabel.text = cellValue; 
} 
    return cell;   
} 

Answer 2

Modificare questa if (section==0)

-if (indexPath.section==0)

Bisogna implementare questa funzione:

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section 
{ 
    if(section == 0) 
     return arrSection1.count; 
     else 
     return arrSection2.count; 
} 

Answer 3

tuo numberOfRowsInSection dovrebbe essere qualcosa di simile:

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { 
    if (section == 0) { 
     return firstArray.count; 
    } else { 
     return secondArray.count; 
    } 
} 

Answer 4

Siete sulla buona strada quasi giusto ....

Consideriamo i tuoi due array sono arrOne e arrTwo .....

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { 
     if(section == 0) 
     return [arrOne count]; 
     else 
     return [arrTwo count]; 
    } 

    - (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]; 
      } 

      if (indexPath.section==0) { 


     ObjectData *theCellData = [arrOne objectAtIndex:indexPath.row]; 
     NSString *cellValue =theCellData.category; 
     NSLog(@"cellValue = %@",cellValue); //To see the value of string cellValue 
     cell.textLabel.text = cellValue; 

     return cell; 

    } 

    else { 
     ObjectData *theCellData = [arrTwo objectAtIndex:indexPath.row]; 
     NSString *cellValue =theCellData.category; 
     cell.textLabel.text = cellValue; 

     return cell;   
    } 
} 

Answer 5

TableView delegato Metodo già dare la sezione come : (NSInteger) sezione .. quindi possiamo anche usare switchCase

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section 
    { 
     switch (section) 
     { 
      case 0: 
       return self.arrMedia.count; 
       break; 
      case 1: 
       return 1; 
       break; 
     } 
     return 0; 
    }

Qui ci sono le pertinenti Swift 3 linee:

func numberOfSections (in tableView: UITableView) -> Int { 
    ... 
    return numberOfSections 
} 

func tableView(_ tableView: UITableView, willDisplayHeaderView view: UIView, forSection section: Int) { 
    //Not necessary, but will let you format the section headers. Example: 
    guard let header = view as? UITableViewHeaderFooterView else { return } 
    header.textLabel?.font = UIFont.boldSystemFont(ofSize: 24) 
    header.textLabel?.textColor = UIColor.darkGray 
    header.textLabel?.textAlignment = .center 
    header.textLabel?.frame = header.frame 
    view.tintColor = UIColor.white 
} 

func tableView(_ tableView: UITableView, willDisplayFooterView view: UIView, forSection section: Int) { 
    //Also not necessary, but clear footers help space out sections 
    view.tintColor = UIColor.clear 
} 

func tableView(_ tableView: UITableView, heightForFooterInSection section: Int) -> CGFloat { 
    //Spacing between sections: 
    return 25 
} 

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { 
    ... 
    return sectionCount 
} 

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { 
    //All your cell setup 
    ... 
    //I call this to get the absolute row number (disregarding sections) 
    let row = getAbsoluteRow_InCurrentSection(indexPath: indexPath) 
    //Now you can use the row number to grab a value from an array or CoreData object and use the value to populate your cell!! 
} 

func getAbsoluteRow_InCurrentSection(indexPath: IndexPath) -> Int { 
    var aggRows = 0 
    if currentListEntity == "GrocTask" { 
     let curSection = indexPath.section 
     for i in 0..<curSection { 
      aggRows += flex1ArrayCnt[i] 
     } 
     aggRows += indexPath.row 
    } 
    return aggRows 
}
