UITable查看numberOfRowsInSection＆cellForRowAtIndexPath錯誤

Question

我的問題是，我有一個UITable，我無法得到numberOfRowsInSection與cellForRowAtIndexPath對應。

我foodCategoryObj具有三個陣列，第一陣列具有6個elems的，第二個有2和第三具有3.

此行 FoodCategory * foodCategoryObj = [appDelegate.foodCategoryArray objectAtIndex：indexPath.row];

..keeps引發此錯誤..索引2超出範圍[0..1]

總的來說，我不知道什麼回報數numberOfRowsInSection

而且arrayCountInt返回數組中的對象的數量我創造了viewWillAppear。

- (NSInteger)tableView:(UITableView *)tblView numberOfRowsInSection:(NSInteger)section { 

NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults]; 
NSString *arrayCountString = [prefs stringForKey:@"arrayCountString"]; 
NSInteger *arrayCountInt = [arrayCountString intValue]; 
//NSLog(@"arrayCountInt.. %i", (arrayCountInt) - 1); 


AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate]; 
NSInteger *arrayCount = [appDelegate.foodCategoryArray count]; 


NSInteger *foodArray = [foodCatArray count]; 


// testing 
NSLog(@"foodCatArray.. %i", foodArray); 


return arrayCountInt; 
} 


- (UITableViewCell *)tableView:(UITableView *)tblView cellForRowAtIndexPath:(NSIndexPath *)indexPath { 
static NSString *CellIdentifier = @"Cell"; 

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; 
if (cell == nil) { 
    cell = [[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier]; 
} 

//NSLog(@"indexPath.row.. %i", (indexPath.row)-1); 
FoodCategory *foodCategoryObj = [appDelegate.foodCategoryArray objectAtIndex:indexPath.row]; 

//Set the cell title 
cell.text = foodCategoryObj.foodName; 


// testing 
//NSLog(@"%@", foodCategoryObj.foodName); 
//NSLog(@"appDelegate.foodCategoryArray.. %@", appDelegate.foodCategoryArray); 

return cell; 
}

你爲什麼不中numberofrowInSection方法返回[appDelegate.foodCategoryArray count]。你應該返回你的foodArray，你返回錯誤的變化
