私は、製品の名前を含むUITableViewを使用するアプリケーションを持っています。これらの製品も最初の文字に基づいてそれぞれのセクションに分割されています。ここでアルファベットのセクションを使用するiPhoneアプリケーションに検索バーを追加しますか？
は私のコードです：私はしているよ何
- (void)viewDidLoad
{
[super viewDidLoad];
//Initialize alphabet array
m_Alphabet = [[NSArray alloc]initWithObjects:@"A",@"B",@"C",@"D",@"E",@"F",@"G",@"H",@"I",@"J",@"K", @"L",@"M",@"N",@"O",@"P",@"Q",@"R",@"S",@"T",@"U",@"V",@"W",@"X",@"Y",@"Z",@"Other", nil];
//Initialize alphabet distionary of arrays
m_AlphabetDictionary = [[NSMutableArray alloc]init];
//Populate distionary with a mutable array for each character
//in the alphabet (plus one "Other" category)
for (int i = 0; i < 27; i++)
[m_AlphabetDictionary insertObject:[[NSMutableArray alloc] init] atIndex: i];
// The number of products in the database
appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
NSMutableArray *tempArray = [[NSMutableArray alloc] init];
//For each product in the appDelgates products
for (Product *product in appDelegate.m_Products){
if ([product.category isEqualToString:productType]){
[tempArray addObject:product];
//firstLetter is equal to the first letter of the products name
NSString * l_FirstLetter = [product.name substringToIndex:1];
//convert firstString to uppercase
l_FirstLetter = [l_FirstLetter uppercaseString];
//The added flag ensures objects whose first letter isn't a letter
//are added to array 26
bool added = NO;
for(int i=0; i<[m_Alphabet count]; i++){
//If the first letter of product name is equal to the letter at index i in theAlphabet
if ([l_FirstLetter isEqualToString:[m_Alphabet objectAtIndex:i]]) {
//Add product to section array for that letter
[[m_AlphabetDictionary objectAtIndex:i] addObject:product];
added = YES;
}
}
//If product hasn't been added to array, add it to "Others" category
if(!added)
[[m_AlphabetDictionary objectAtIndex:26] addObject:product];
}
}
//Set navigation controller title
self.title = productType;
}
//Number of sections is equal to the length of the m_Alphabet array
//Letters A-Z plus "Other"
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return [m_Alphabet count];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [[m_AlphabetDictionary objectAtIndex:section] count];
}
- (NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView
{
return m_Alphabet;
}
- (NSInteger)tableView:(UITableView *)tableView sectionForSectionIndexTitle:(NSString *)title atIndex:(NSInteger)index
{
return [m_Alphabet indexOfObject:title];
}
- (NSString *)tableView:(UITableView *)aTableView titleForHeaderInSection:(NSInteger)section
{
if ([[m_AlphabetDictionary objectAtIndex:section] count]==0)
return nil;
return [m_Alphabet objectAtIndex:section];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSLog(@"Cell for row");
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
if([self.productType isEqualToString:@"All"]){
Product *product = (Product *) [appDelegate.m_Products objectAtIndex:indexPath.row];
cell.textLabel.text = product.name;
// Configure the cell.
return cell;
}
else {
//Instead of using appDelegate.products use the new array that will be filled
//by the numberOfReowsInSection method
Product *product = (Product *)[[m_AlphabetDictionary objectAtIndex:indexPath.section] objectAtIndex:indexPath.row];
cell.textLabel.text = product.name;
// Configure the cell.
return cell;
}
}
だけで、「すべての連絡先」セクションの検索バーのように振る舞う私のテーブルビューの上部に検索バーを追加することですiPhone連絡先アプリケーション。 I.私が検索すると、すべてのセクションが消え、検索バーが再び空白になるまで検索結果だけが表示されます。
誰でも正しい方向に向けることができますか？あなたがする必要があるよう
おかげで、
