私の最後の質問から、plistから画像を取得するようにコードを変更しました..私の以前の質問はこのリンクにあります(配列から選択した画像を取得して別のビューに表示する)

私のコードは次のとおりです。

- (void)viewDidLoad
{

 [super viewDidLoad];

    NSDictionary *dictionary = [NSDictionary dictionaryWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"ImageList" ofType:@"plist"] ];
self.arrayImages = [dictionary objectForKey:@"Images"];

selectedTag = 0;
images = [[NSMutableArray alloc]init];
lists = [[NSMutableArray alloc]init];
imageScroll.delegate = self;
imageScroll.scrollEnabled = YES;
int scrollWidth = 768;
imageScroll.contentSize = CGSizeMake(scrollWidth,605);
int xOffset = 0;
int total = self.arrayImages.count;

for(index=0; index < total; index++)
{
    dict = [self.arrayImages objectAtIndex:index];

    UIButton *img = [UIButton buttonWithType:UIButtonTypeCustom];
    UILabel *lab = [[UILabel alloc] init];
    img.tag = index;
    selectedTag = img.tag;
    img.bounds = CGRectMake(10, 10, 50, 50);
    img.frame = CGRectMake(50+xOffset, 120, 270, 350);
    lab.bounds = CGRectMake(20, 20, 150, 150);
    lab.frame = CGRectMake(160+xOffset, 500, 90, 50);
    lab.font = [UIFont systemFontOfSize:24];
    [img setImage:[UIImage imageNamed:[dict objectForKey:@"imagesName"]] forState:UIControlStateNormal];
    lab.text = [NSString stringWithFormat:[dict objectForKey:@"listName"]];
    [images insertObject:img atIndex:index];
    [lists insertObject:lab atIndex:index];
    imageScroll.contentSize = CGSizeMake(scrollWidth+xOffset,510);
    [imageScroll addSubview:[images objectAtIndex:index]];
    [imageScroll addSubview:[lists objectAtIndex:index]];
    xOffset += 370;

    [img addTarget:self action:@selector(newView:) forControlEvents:UIControlEventTouchUpInside];
    selectedTag = img.tag;
}    
}

-(void)newView:(id)sender{

NSLog(@"%@",sender);
int newIndex;
newIndex = [sender tag];
NSLog(@"Selected Tag :%d",newIndex);
CGRect rec = CGRectMake(0, 0, 250, 250);
[self setView:[[[UIView alloc] initWithFrame:rec] autorelease]];
[[self view] setBackgroundColor:[UIColor whiteColor]];
UIImage *img = [UIImage imageNamed:[[dict objectForKey:@"imagesName"]objectAtIndex:newIndex]];

UIImageView *im = [[UIImageView alloc] initWithImage:img];
UILabel *lab1 = [[UILabel alloc] init];
lab1.text = [NSString stringWithFormat:[[dict objectForKey:@"listName"] objectAtIndex:newIndex]];


lab1.bounds = CGRectMake(20, 20, 150, 150);
lab1.frame = CGRectMake(360, 600, 90, 50);
lab1.font = [UIFont systemFontOfSize:24];
im.bounds = CGRectMake(10, 10, 50, 50);
im.frame = CGRectMake(200, 120, 370, 450);
[[self view] addSubview:im];
[[self view] addSubview:lab1];
}

私のPlist出力：

   Images =     (
            {
        Contents = "Sea While Tsunami";
        imagesName = "sea1.jpg";
        listName = Sea1;
    },
            {
        Contents = "Sea While Tsunami";
        imagesName = "sea2.jpg";
        listName = Sea2;
    },
            {
        Contents = "Sea While Tsunami";
        imagesName = "sea3.jpg";
        listName = Sea3;
    },
            {
        Contents = "Sea While Tsunami";
        imagesName = "sea4.jpg";
        listName = Sea4;
    },
            {
        contents = "Sea While Tsunami";
        imagesName = "sea5.png";
        listName = Sea5;
    },


 ),

次のようにエラーが発生します：

<UIButton: 0x714f3a0; frame = (420 120; 270 350); opaque = NO; tag = 1; layer = <CALayer: 0x4f460>>

2013-02-12 12:58:46.975 image[2546:11303] -[__NSCFString objectAtIndex:]: unrecognized selector sent to instance 0x714bd60
2013-02-12 12:58:46.976 image[2546:11303] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFString objectAtIndex:]: unrecognized selector sent to instance 0x714bd'

libc++abi.dylib: terminate called throwing an exception

plistは正常に動作します..最初のビューではうまく表示されます..しかし、選択した画像を別のビューにフェッチすると、このエラーが発生します..フェッチした画像を初期化するのを間違えていますnewView:..誰かがこの問題を解決するのを手伝ってくれますか?? 前もって感謝します..

で宣言するYurSecondViewController.h

UIImage *img;
@property(nonatomic,retain)UIImage *img;

makepropertyとsynthesize imgを確認してください。

FirstViewControllerあなたがそれを持っている場所で: image-

YurSecondViewController *View=[[[YurSecondViewController alloc]init];
View.img=[UIImage imageNamed:@"Default.png"];
[self.navigationController pushViewController:View animated:YES];

画像を表示する必要がある YurSecondViewController.m で:-

UIImageView *imgView=[[UIImageView alloc]initWithFrame:CGRectMake(50, 50, 100, 100)];
[imgView setImage:self.img];
[self.view addSubview:imgView];
