我正在iOS 7.0上開發我的第一個使用Xcode 5.1的iPad應用程序,並且我使用的是UICollectionView
。UICollectionView單元在秒數或錄像屏幕後消失
Here is an sketch of my storyboard
我CollectionViewController被納入我最初的控制器的看法時,我點擊導航欄中的第一個選項卡中。
細胞在幾秒鐘後消失或當我在屏幕上點擊某處時消失。
如果我把CollectionViewController作爲初始視圖控制器,單元格就可以!
我不明白! 請幫助。
#import "ActiviteViewController.h"
#import "AppDelegate.h"
#import "Embarcation.h"
#import "CollectionActiviteCellController.h"
@interface ActiviteViewController()

self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self; }

[super viewWillAppear:animated];
[[self view] setFrame: CGRectMake(0, 0, 1024, 618)]; }

return YES; }

[super viewDidLoad];

self.embarcationsArray = [appDelegate getAllPayments];
[self.collectionView reloadData]; }

[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated. }

return 1; }

// Return the number of rows in the section.
return [self.embarcationsArray count]; }

CollectionActiviteCellController *myCell = [collectionView dequeueReusableCellWithReuseIdentifier:@"MonEmbarcation"
forIndexPath:indexPath];
Embarcation * embarcation = [self.embarcationsArray objectAtIndex:indexPath.row];
myCell.labelEmbarcation.text = [NSString stringWithFormat:@"%@, %@ ",embarcation.nom,embarcation.etat];
NSLog([NSString stringWithFormat:@"%@, %@ ",embarcation.nom,embarcation.etat]);
return myCell; }

您是否正確設置了您的數據源?當您用來填充collectionCells的數組爲空時,您可能正在執行reloadData。還有你的註冊CustomCell?無論哪種方式。發佈所有與CollectionView相關的代碼 –
我發佈了所有revenant代碼,我試圖刪除reloadData但沒有任何變化 –
無需刪除reloadData:O!你只需要檢查你的'embarcationsArray'中的狀態和數據。你可以替換'[appDelegate getAllPayments];'用硬編碼數組作爲實驗?此外,我沒有看到你註冊你的單元格(或提到這一點),所以你可以添加這行到你的viewDidLoad方法? [self.collectionView registerClass:[CollectionActiviteCellController class] forCellWithReuseIdentifier:@「CollectionActiviteCellController」] ;.順便說一句我假設你正確設置你的'CollectionActiviteCellController'來擴展'UICollectionViewCell'! –
