从数组中提取选定的图像以在另一个视图中显示

我试图从图像数组中获取选定的图像。所选的图像应显示在新的视图中。

- (void)viewDidLoad{ [super viewDidLoad]; selectedTag = 0; imagesName = [[NSArray alloc]initWithObjects:@"nature1.jpg",@"nature2.jpg",@"nature3.jpg",@"nature4.jpg",@"nature5.png",@"nature6.jpg",nil]; images = [[NSMutableArray alloc]init]; imageScroll.delegate = self; imageScroll.scrollEnabled = YES; int scrollWidth = 768; imageScroll.contentSize = CGSizeMake(scrollWidth,605); int xOffset = 0; for(index=0; index < [imagesName count]; index++) { UIButton *img = [UIButton buttonWithType:UIButtonTypeCustom]; img.tag = index; selectedTag = img.tag; img.bounds = CGRectMake(10, 10, 50, 50); img.frame = CGRectMake(50+xOffset, 120, 270, 350); NSLog(@"image: %@",[imagesName objectAtIndex:index]); [img setImage:[UIImage imageNamed:[imagesName objectAtIndex:index]] forState:UIControlStateNormal]; [images insertObject:img atIndex:index]; imageScroll.contentSize = CGSizeMake(scrollWidth+xOffset,510); [imageScroll addSubview:[images objectAtIndex:index]]; xOffset += 370; [img addTarget:self action:@selector(newView:) forControlEvents:UIControlEventTouchUpInside]; selectedTag = img.tag; } } -(void)newView:(id)sender{ NSLog(@"%@",sender); int f; f = [sender tag]; CGRect rec = CGRectMake(0, 0, 250, 250); [self setView:[[[UIView alloc] initWithFrame:rec] autorelease]]; [[self view] setBackgroundColor:[UIColor grayColor]]; UIImageView *im = [[UIImageView alloc] initWithImage:[imagesName objectAtIndex:f]]; im.bounds = CGRectMake(10, 10, 50, 50); im.frame = CGRectMake(250, 120, 270, 350); [[self view] addSubview:im]; } 

任何人都可以帮我把选定的图像提取到另一个视图？ 提前致谢..

你正在设置string，而不是图像。 使用这段代码

 UIImage *img = [UIImage imageNamed:[imagesName objectAtIndex:f]]; UIImageView *im = [[UIImageView alloc] initWithImage:img];
