Objective-C use of undeclared identifier 'numberOfSectionsInTableView' - objective-c

Question

Not sure where I went wrong. My understanding is that importing UIKit will enable use of the numberOfSectionsInTableView method... Any help is appreciated.
//HEADER
#import <UIKit/UIKit.h>
#interface MainScrollingTableVC : UITableViewController <UITableViewDelegate, UITableViewDataSource> {
int selectedIndex;
NSMutableArray *titleArray;
NSArray *subtitleArray;
NSArray *textArray;
}
#end
//IMPLEMENTATION
#import "MainScrollingTableVC.h"
#import "MainExpandingCellTableViewCell.h"
#interface MainScrollingTableVC ()
#property (strong, nonatomic) IBOutlet UITableView *tableView;
#end
#implementation MainScrollingTableVC
- (void)viewDidLoad {
[super viewDidLoad];
self.tableView.delegate = self;
self.tableView.dataSource = self;
//index = -1 means no cell is expanded or should expand
selectedIndex = -1;
titleArray = [[NSMutableArray alloc] init];
NSString *string;
//create consecutive array of 8 numbers. 1...2...etc...
for(int ii = 1; ii <= 8; ii++) {
string = [[NSString alloc] initWithFormat:#"Row %i", ii];
[titleArray addObject:string];
}
subtitleArray = [[NSArray alloc] initWithObjects:#"First row", #"Second row", #"Third row", #"Fourth row", #"Fifth row", #"Sixth row", #"Seventh row", #"Eigth row", nil];
textArray = [[NSArray alloc] initWithObjects:#"Apple", #"Orange", #"Grape", #"Banana", #"Kiwi", #"Blueberry", #"Apricot", #"Lemon", nil];
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return titleArray.count;
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *cellIdentifier = #"MainExpandingCell";
MainExpandingCell *cell = (MainExpandingCell *)[tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if(cell == nil) {
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"MainExpandingCell" owner:self options:nil];
cell = [nib objectAtIndex:0];
}
if(selectedIndex == indexPath.row) {
//Do expanded cell stuff
} else {
//Do closed cell stuff
}
cell.titleLabel.text = [titleArray objectAtIndex:indexPath.row];
cell.timeLabel.text = [subtitleArray objectAtIndex: indexPath.row]; //CHECK VARS
cell.textLabel.text = [textArray objectAtIndex:indexPath.row];
int etaLabel = (indexPath.row + 1) * 25;
cell.etaLabel.text = [NSString stringWithFormat:#"%i", eta]
cell.clipsToBounds = YES;
return cell;
}
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}

You are declaring your methods inside the viewDidLoad method. Objective-C doesn't support method nesting. Fix your whole code with its formatting and add the missing } accordingly.
