表視圖無法正常工作。

我正在嘗試創建一個實用的table view（沒有xib和storyboards），但食物數組並沒有在表格視圖中顯示出來。我將在視圖控制器中發佈我的所有代碼。表視圖無法正常工作。

Viewcontroller.h

@interface searchViewController :  ViewController<UITextFieldDelegate,UISearchBarDelegate,UITableViewDataSource>{ 
    NSMutableArray * getterms; 
} 

@property (strong, nonatomic) NSMutableArray* allTableData; 
@property (strong, nonatomic) NSMutableArray* filteredTableData; 
@property (nonatomic, assign) bool isFiltered; 
@property (nonatomic, retain) UITableView *tableView;

Viewcontroller.m

-(void)viewDidLoad{ 
    UITableView *tableView = [[UITableView alloc] initWithFrame:CGRectMake(10.0, 10.0, 1000.0, 200.0) style:UITableViewStylePlain]; 
[self.view addSubview:tableView]; 
    self.tableView.dataSource = self; 

    allTableData = [[NSMutableArray alloc] initWithObjects: 
       [[Food alloc] initWithName:@"Steak" andDescription:@"Rare"], 
       [[Food alloc] initWithName:@"Steak" andDescription:@"Medium"], 
       [[Food alloc] initWithName:@"Salad" andDescription:@"Caesar"], 
       [[Food alloc] initWithName:@"Salad" andDescription:@"Bean"], 
       [[Food alloc] initWithName:@"Fruit" andDescription:@"Apple"], 
       [[Food alloc] initWithName:@"Potato" andDescription:@"Baked"], 
       [[Food alloc] initWithName:@"Potato" andDescription:@"Mashed"], 
       [[Food alloc] initWithName:@"Bread" andDescription:@"White"], 
       [[Food alloc] initWithName:@"Bread" andDescription:@"Brown"], 
       [[Food alloc] initWithName:@"Hot Dog" andDescription:@"Beef"], 
       [[Food alloc] initWithName:@"Hot Dog" andDescription:@"Chicken"], 
       [[Food alloc] initWithName:@"Hot Dog" andDescription:@"Veggie"], 
       [[Food alloc] initWithName:@"Pizza" andDescription:@"Pepperonni"], 
       nil ]; 
      } 

    - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { 

static NSString *MYCellIdentifier = @"MyCellIdentifier"; 

UITableViewCell *cell = [self.tableView dequeueReusableCellWithIdentifier:MYCellIdentifier]; 
if (cell == nil) 
    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:MYCellIdentifier]; 

Food* food; 
if(isFiltered) 
    food = [filteredTableData objectAtIndex:indexPath.row]; 
else 
    food = [allTableData objectAtIndex:indexPath.row]; 

cell.textLabel.text = food.name; 
cell.detailTextLabel.text = food.description; 

return cell; 

    } 
    - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView 
    { 
return 1; 
    } 


    - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { 
int rowCount; 
if(self.isFiltered) 
    rowCount = filteredTableData.count; 
else 
    rowCount = allTableData.count; 

return rowCount; 
} 

    - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { 
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]; 

if (self) { 

} 
return self; 
}
