このメソッドがスキップされないようにするために、RoomItemに必要な重要なものはありますか？これは私の詳細ビューコントローラの最初のものであり、デバッグモードでは継続的にスキップされます。ばかばかしいほど単純なものが欠けていると確信していますが、私はそれを何時間も見つめ続けており、それが何であるかを理解することができません。
@interface DetailViewController ()
- (void)configureView;
@end
@implementation DetailViewController
- (void)setDetailItem:(RoomItem *)newDetailItem
{
if (_detailItem != newDetailItem) {
_detailItem = newDetailItem;
// Update the view.
[self configureView];
}
}
- (void)configureView
{
// Update the user interface for the detail item.
if (self.detailItem) {
[_roomTxt setText:[_detailItem room]];
[_buildingTxt setText:[_detailItem building]];
[_dateTxt setText:[self dateCreatedString]];
[_buildingImageView setImage:[_detailItem buildingImage]];
_oi = [_detailItem objectIndex];
}
}
新規および既存のdetailViewControllersを割り当てて初期化するMasterViewController（ルートテーブルビュー）メソッド
- (void)insertNewObject:(id)sender
{
//add button invokes this
DetailViewController *ivc = [[DetailViewController alloc] init];
[self.navigationController pushViewController:ivc animated:YES];
NSLog(@"detailViewController allocated and initialized: %@", ivc);
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
if (!self.detailViewController) {
self.detailViewController = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:nil];
NSLog(@"detailViewController initialized: %@", self.detailViewController);
}
//navigates to detailViewController and passes it the item's data
self.detailViewController.detailItem = [[[RoomList sharedStore] getAllItems] objectAtIndex:[indexPath row]];
[self.navigationController pushViewController:self.detailViewController animated:YES];
}
RoomList：sharedStoreから、詳細ビューコントローラに必要なすべてのものを渡す必要があるtableView：didSelectRowAtIndexPathメソッドを次に示します。
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
if (!self.detailViewController) {
self.detailViewController = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:nil];
}
//navigates to detailViewController and passes it the item's data
self.detailViewController.detailItem = [[[RoomList sharedStore] getAllItems] objectAtIndex:[indexPath row]];
[self.navigationController pushViewController:self.detailViewController animated:YES];
}
...およびRoomItem.mファイル：
- (void)awakeFromFetch
{
[super awakeFromFetch];
UIImage *pic = [UIImage imageWithData:[self buildingThumbnailData]];
[self setPrimitiveValue:pic forKey:@"buildingThumbnail"];
}
- (id)initWithRoom:(NSString *)room Building:(NSString *)building
{
self = [super init];
if (self) {
[self setRoom:room];
[self setBuilding:building];
}
return self;
}
