iOS 7에서 UI 컬렉션보기가 표시되지 않음

Question

내 응용 프로그램에서 UICOllectionView를 사용했지만 IOS 6.0에서 작동했지만 IOS7에서 실행하려고하면 콜렉션보기가 표시되지 않습니다. i saw this question 나는 주어진 답변을 시도했지만 그만했습니다. dint work, 그리고 나서 콜렉션 뷰의 moveItemAtIndexPath 메소드를 사용하고 셀을 앞뒤로 바꾼 다음 셀이 표시되지만 셀을 아래로 스크롤하면 사라집니다. 내가 사용하는 코드는 here

코드를 공부합니다. & 변경합니다.

이 코드를 사용해보십시오. Code

- (void)viewDidLoad 
{ 
    [super viewDidLoad]; 
     // Do any additional setup after loading the view, typically from a nib. 
    UICollectionViewFlowLayout *layout=[[UICollectionViewFlowLayout alloc] init]; 
    _collectionView=[[UICollectionView alloc] initWithFrame:CGRectMake(130, 100, 780, 1024) collectionViewLayout:layout]; 
    _collectionView.autoresizesSubviews= YES; 
    [_collectionView setDataSource:self]; 
    [_collectionView setDelegate:self]; 
    _collectionView.backgroundColor = [UIColor clearColor]; 

    [_collectionView registerClass:[UICollectionViewCell class] forCellWithReuseIdentifier:@"cellIdentifier"]; 

    [self.view addSubview:_collectionView]; 

} 

- (void)didReceiveMemoryWarning 
{ 
    [super didReceiveMemoryWarning]; 
    // Dispose of any resources that can be recreated. 
} 
- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section 
{ 
    return 12; 
} 
-(NSInteger)numberOfSectionsInCollectionView:(UICollectionView *)collectionView 
{ 
    return 1; 
} 
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath 
{ 
    UICollectionViewCell *cell=[collectionView dequeueReusableCellWithReuseIdentifier:@"cellIdentifier" forIndexPath:indexPath]; 
    UIView *headertitle = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 375, 20)]; 
    UILabel *titlelabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 100, 20)]; 
    titlelabel.text = [NSString stringWithFormat:@"graphtitle%d",indexPath.row]; 
    titlelabel.textColor = [UIColor blackColor]; 
    titlelabel.font = [UIFont fontWithName:@"Knewave" size:15.0f]; 
    titlelabel.backgroundColor = [UIColor clearColor]; 
    [headertitle addSubview:titlelabel]; 
    headertitle.backgroundColor = [UIColor whiteColor]; 
    UIWebView *web = [[ UIWebView alloc]initWithFrame:CGRectMake(0, 20, 375, 150)]; 
    NSString *htmlFile = [[NSBundle mainBundle] pathForResource:@"test" ofType:@"html"]; 
    NSData *htmlData = [NSData dataWithContentsOfFile:htmlFile]; 
    web.scalesPageToFit = YES; 
    [web loadData:htmlData MIMEType:@"text/html" textEncodingName:@"UTF-8" baseURL:[NSURL URLWithString:@""]]; 
    UIButton *button1 = [UIButton buttonWithType:UIButtonTypeCustom]; 
    button1.backgroundColor = [UIColor clearColor]; 
    button1.frame = CGRectMake(320, 3, 50, 17); 
    [button1 setTitle:@"view" forState:UIControlStateNormal]; 

    [headertitle addSubview:button1]; 
    headertitle.backgroundColor = [UIColor grayColor]; 

    [cell addSubview:headertitle]; 
    [cell addSubview:web]; 

    cell.layer.shadowColor = [[UIColor blackColor]CGColor]; 
    cell.layer.shadowOffset = CGSizeMake(20, 20); 
    cell.layer.borderColor = [[UIColor blackColor] CGColor]; 
    cell.layer.borderWidth =1; 
    //cell.alpha = 1.0f; //Changed here 
    return cell; 
}
