    [data_ release], data_ = nil; 
    [super dealloc]; 
} 

- (id)init 
{ 
    self = [super init]; 
    if (self) { 
     data_ = [[NSMutableArray alloc] init]; 
     NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys:[UIImage imageNamed:@"IMG_0694_th.jpg"], @"thumbnail", [UIImage imageNamed:@"IMG_0694.JPG"],  @"fullsize", nil]; 
     [data_ addObject:dict]; 
    } 
    return self; 
} 

- (NSInteger)numberOfPhotos 
{ 
    NSInteger count = 1000; [data_ count]; 
    return count; 
} 

// Implement either these, for synchronous images… 
- (UIImage *)imageAtIndex:(NSInteger)index 
{ 
    NSDictionary *dict = [data_ objectAtIndex:0]; 
    UIImage *image = [dict objectForKey:@"fullsize"]; 
    return image; 
} 

- (UIImage *)thumbImageAtIndex:(NSInteger)index 
{ 
    NSDictionary *dict = [data_ objectAtIndex:0]; 
    UIImage *image = [dict objectForKey:@"thumbnail"]; 
    return image; 
}

更改以下方法：

- (id)init 
{ 
    self = [super init]; 
    if (self) { 
     data_ = [[NSMutableArray alloc] init]; 
     NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys:[UIImage imageNamed:@"IMG_0694_th.jpg"], @"thumbnail", [UIImage imageNamed:@"IMG_0694.JPG"],  @"fullsize", nil]; 
     //Add all the images you have in the data. Currently you are adding only one image here. 

     [data_ addObject:dict]; 
    } 
    return self; 
} 

- (NSInteger)numberOfPhotos 
{ 
    return [data_ count]; 
} 


- (UIImage *)imageAtIndex:(NSInteger)index 
{ 
    NSDictionary *dict = [data_ objectAtIndex:index]; 
    UIImage *image = [dict objectForKey:@"fullsize"]; 
    return image; 
} 

- (UIImage *)thumbImageAtIndex:(NSInteger)index 
{ 
    NSDictionary *dict = [data_ objectAtIndex:index]; 
    UIImage *image = [dict objectForKey:@"thumbnail"]; 
    return image; 
} 

希望這有助於.. :)
