したがって、私はテーブルビューに3つのセルがあり、すべてラベル名とユーザーのデータを収集するためのUITextFieldを持っています。以下のように彼らが設定されていますxCode：UITableViewCellのすべての1つのテキストフィールドだけが必要なように動作します
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
nameTextField = [[UITextField alloc] initWithFrame:CGRectMake(110, 10, 185, 30)];
emailTextField = [[UITextField alloc] initWithFrame:CGRectMake(110, 10, 185, 30)];
messageTextField = [[UITextField alloc] initWithFrame:CGRectMake(110, 10, 185, 30)];
nameTextField.delegate = self;
emailTextField.delegate = self;
messageTextField.delegate = self;
cells *cells = nil;
cells = [cellsarray objectAtIndex:indexPath.row];
cell.textLabel.text = cells.name;
[cell.textLabel sizeToFit];
if (indexPath.row == 0) {
nameTextField.adjustsFontSizeToFitWidth = YES;
nameTextField.textColor = [UIColor blackColor];
nameTextField.placeholder = @"Your name";
nameTextField.keyboardType = UIKeyboardTypeDefault;
nameTextField.returnKeyType = UIReturnKeyGo;
nameTextField.backgroundColor = [UIColor whiteColor];
nameTextField.autocorrectionType = UITextAutocorrectionTypeNo; // no auto correction support
nameTextField.autocapitalizationType = UITextAutocapitalizationTypeNone; // no auto capitalization support
nameTextField.textAlignment = UITextAlignmentLeft;
nameTextField.tag = 0;
//playerTextField.delegate = self;
nameTextField.clearButtonMode = UITextFieldViewModeNever; // no clear 'x' button to the right
[nameTextField setEnabled: YES];
[nameTextField addTarget:self action:@selector(textFieldDidChange1:) forControlEvents:UIControlEventEditingChanged];
[cell.contentView addSubview:nameTextField];
}
if (indexPath.row == 1) {
emailTextField.adjustsFontSizeToFitWidth = YES;
emailTextField.textColor = [UIColor blackColor];
emailTextField.placeholder = @"Your email";
emailTextField.keyboardType = UIKeyboardTypeEmailAddress;
emailTextField.returnKeyType = UIReturnKeyGo;
emailTextField.backgroundColor = [UIColor whiteColor];
emailTextField.autocorrectionType = UITextAutocorrectionTypeNo; // no auto correction support
emailTextField.autocapitalizationType = UITextAutocapitalizationTypeNone; // no auto capitalization support
emailTextField.textAlignment = UITextAlignmentLeft;
emailTextField.tag = 1;
//playerTextField.delegate = self;
emailTextField.clearButtonMode = UITextFieldViewModeNever; // no clear 'x' button to the right
[emailTextField setEnabled: YES];
[emailTextField addTarget:self action:@selector(textFieldDidChange2:) forControlEvents:UIControlEventEditingChanged];
[cell.contentView addSubview:emailTextField];
}
if (indexPath.row == 2) {
messageTextField.adjustsFontSizeToFitWidth = YES;
messageTextField.textColor = [UIColor blackColor];
messageTextField.placeholder = @"Your message";
messageTextField.keyboardType = UIKeyboardTypeDefault;
messageTextField.returnKeyType = UIReturnKeyGo;
messageTextField.backgroundColor = [UIColor whiteColor];
messageTextField.autocorrectionType = UITextAutocorrectionTypeNo; // no auto correction support
messageTextField.autocapitalizationType = UITextAutocapitalizationTypeNone; // no auto capitalization support
messageTextField.textAlignment = UITextAlignmentLeft;
messageTextField.tag = 2;
//playerTextField.delegate = self;
messageTextField.clearButtonMode = UITextFieldViewModeNever; // no clear 'x' button to the right
[messageTextField setEnabled: YES];
[messageTextField addTarget:self action:@selector(textFieldDidChange3:) forControlEvents:UIControlEventEditingChanged];
[cell.contentView addSubview:messageTextField];
}
しかし、3番目のセル、またはmessageTextFieldは、命令を次の一つだけのようです。次のコードでは、ユーザーがmessageTextFieldを返すときにNSLog "Hello"となるように設定しました。
- (BOOL)textFieldShouldReturn:(UITextField *)textField {
NSLog(@"returned");
if (messageTextField == textField) {
NSLog(@"Hello");
}
}
これは正常に動作しますが、私は私に戻ったとき、私は
if (messageTextField == textField)
nameTextFieldが私の最初のセルであり、それはまだ唯一のNSLog "こんにちは" は意志
if (nameTextField == textField)
なぜプロトタイプセルを使用しないのですか？ –
あなたのcellForRowが大きすぎると複雑です。また、あなたのセルにUITextFieldを繰り返し追加しています。あなたの細胞が効果的に再利用されているかどうかわかりません –
