Any.DO アプリのコピーを作成しようとしています。はtableHeaderView"NewTaskCell" ビューで、 と が含まれていUITextFieldます。何らかの理由で、キーボードが表示された後、tableView を一番下までスクロールできません。これが私が試したことです：
- tableView のフレームを変更する
- tableView の境界を変更する
- tableView の contentSize の変更
- キーボードを閉じた後のフッター ビューの更新
キーボードが表示された場合にのみ発生するため、キーボードまたはテキストフィールドのいずれかと関係がある必要があります。
下のアニメーションでは、プラス ボタンをクリックしてキーボードを表示すると、tableView が一番下までスクロールできないことがわかります。その後、プラスボタンをクリックしてキーボードを表示しないと、下までスクロールできます。
プロジェクト全体のソース コードは次のとおりです。
これが私の viewDidLoad メソッドの内容です。
- (void)viewDidLoad
{
[super viewDidLoad];
[[self tableView] setAllowsSelection: YES];
[[self tableView] setShowsVerticalScrollIndicator: NO];
// Make sure there aren't any empty cells showing at the bottom
// Caused initial error [[self tableView] setTableFooterView: [UIView new]];
// Fixes error at first, until the keyboard shows up
UIView *footer = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 1, 45)];
footer.backgroundColor = [UIColor clearColor];
self.tableView.tableFooterView = footer;
// Make the separators look right
[[self tableView] setSeparatorStyle: UITableViewCellSeparatorStyleSingleLine];
[[self tableView] setSeparatorColor: [UIColor colorWithWhite: 0.95 alpha: 1]];
UINib *nibTwo = [UINib nibWithNibName: @"TaskCell" bundle: nil];
[[self tableView] registerNib: nibTwo forCellReuseIdentifier: @"TaskCell"];
// Create the new task cell to go above the tableView
// --------------------------------------------------
NewTaskCell *myNewTaskCell = [[NewTaskCell alloc] init];
// Need to access it later to show the keyboard
[self setTheNewTaskCell: myNewTaskCell];
[[theNewTaskCell view] setFrame: CGRectMake(0, 0, 320, 44)];
[[[theNewTaskCell reminderButton] layer] setOpacity: 0];
[[[theNewTaskCell locationButton] layer] setOpacity: 0];
[[[theNewTaskCell addTaskButton] layer] setOpacity: 0];
// Assign a method for each button
[[theNewTaskCell reminderButton] addTarget:self action:@selector(addReminder) forControlEvents: UIControlEventTouchUpInside];
[[theNewTaskCell locationButton] addTarget:self action:@selector(addLocationReminder) forControlEvents: UIControlEventTouchUpInside];
[[theNewTaskCell addTaskButton] addTarget:self action:@selector(addTaskToList) forControlEvents: UIControlEventTouchUpInside];
// Separator view
UIView *separatorView = [[UIView alloc] initWithFrame: CGRectMake(0, 43, 320, 1)];
[separatorView setBackgroundColor: [UIColor colorWithWhite: 0.5 alpha: 0.2]];
[[theNewTaskCell view] addSubview: separatorView];
[[self tableView] setTableHeaderView: [theNewTaskCell view]];
[[self tableView] setContentInset: UIEdgeInsetsMake(-44, 0, 0, 0)];
// ---------------------------------------------------
// For Reordering
[[self tableView] setEditing: YES];
UILongPressGestureRecognizer *longPress = [[UILongPressGestureRecognizer alloc] initWithTarget: self action: @selector(longPress:)];
[longPress setMinimumPressDuration: 0.3];
[longPress setDelaysTouchesBegan: YES];
