從nsdata NSInvalidArgumentException'回推圖像'，原因：' - [UIImage length]

我添加圖像在NSMutableArray比我轉換它在NSData和agaun我存儲該圖像在其他NSMutableArray。但是，當我轉換回圖像，讓我錯誤從nsdata NSInvalidArgumentException'回推圖像'，原因：' - [UIImage length]

我的代碼是

NSData *Puzzleimage; 
PuzzleImg = [[NSMutableArray alloc] init]; 
TriangleImg = [[NSMutableArray alloc] init]; 

[PuzzleImg addObject:[UIImage imageNamed:@"Triangle_1.png"]]; 
    [PuzzleImg addObject:[UIImage imageNamed:@"Triangle_2.png"]]; 
    [PuzzleImg addObject:[UIImage imageNamed:@"Triangle_3.png"]]; 
    [PuzzleImg addObject:[UIImage imageNamed:@"Triangle_4.png"]]; 
    [PuzzleImg addObject:[UIImage imageNamed:@"Triangle_5.png"]]; 


    for (int l=0; l<[PuzzleImg count]; l++) { 
     Puzzleimage = UIImagePNGRepresentation([PuzzleImg objectAtIndex:l]); 
     [TriangleImg addObject:Puzzleimage];

Retrive中滾動查看

CGRect scrollViewFrame = CGRectMake(10, 60, 300, 350); 
     PuzzleList = [[UIScrollView alloc] initWithFrame:scrollViewFrame]; 
     [self.view addSubview:PuzzleList]; 

     int y1=10; 
     int y2=10; 
     if ([PuzzleImg count] >0) 
     { 
      for(int i=0;i<[PuzzleImg count];i++) 
      { 
        UIImage *SolImg = [[UIImage alloc] initWithData:[PuzzleImg objectAtIndex:i]]; 
        UIButton *btn =[[UIButton alloc]initWithFrame:CGRectMake(10, y1, 100, 100)]; 
        [btn setBackgroundImage:SolImg forState:UIControlStateNormal]; 
        btn.tag = i; 
        [btn addTarget:self action:@selector(SelectPuzzleButtonClick:) forControlEvents:UIControlEventTouchUpInside]; 

        [PuzzleList addSubview:btn]; 
        y1=y1+110; 
     } 
}

誤差 *錯誤是顯示器上線:: UIImage SolImg = [[UIImage alloc] initWithData：[PuzzleImg objectAtIndex：i]];

是NSData的，請看到我的更新感謝 – 2013-04-10 05:34:56

你發送'TriangleImg'到第二代碼段或只'PuzzleImg '？ – Alexander 2013-04-10 05:36:42

嘗試從此改變......

UIImage *SolImg = [[UIImage alloc] initWithData:[PuzzleImg objectAtIndex:i]];

到...

UIImage *SolImg = [[UIImage alloc] initWithData:[TriangleImg objectAtIndex:i]];

我認爲這是足以讓你

見你加UIImage爲NSData在TriangleImgNSMutableArray對象不PuzzleImgNSMutableArray對象，以便使用波紋線

UIImage *SolImg = [[UIImage alloc] initWithData:[TriangleImg objectAtIndex:i]];

，而不是這種波紋管生產線。 ..

UIImage *SolImg = [[UIImage alloc] initWithData:[PuzzleImg objectAtIndex:i]];
