如何在 xcode,iphone 中将字符串值添加到 UIImage 中。显示的代码表示要插入数组中的图像

Question

如何将字符串值添加到 xcode、iphone 中的 UIImage 中。显示的代码表示要插入到数组中的图像。如果我运行此代码，则图像列表将显示在屏幕上，如果我点击任何一张图像图像列表中必须全屏显示。我是 iPhone 新手，我希望有人能帮我解决这个问题。将第二个图像附加到块时，检索空值

    NSMutableArray *images = [[NSMutableArray alloc] init];

    [images addObject:@"item1.jpg"];
    [images addObject:@"item2.jpg"];
    [images addObject:@"item3.jpg"];
    [images addObject:@"item4.jpg"];
    [images addObject:@"item5.jpg"];
    [images addObject:@"item6.jpg"];
    [images addObject:@"item7.jpg"];
    [images addObject:@"item8.jpg"];
    [images addObject:@"item9.jpg"];

    for (int y = 0; y < rows; y++) {
        for (int x = 0; x < columns; x++) {
            CGPoint blockOrigin = CGPointMake(x * blockSize.width, y * blockSize.height);
            CGRect blockFrame;
            blockFrame.size = blockSize;
            blockFrame.origin = blockOrigin;
            NSString *imagename=[[NSString alloc]init];
            imagename=[images objectAtIndex:k];

            NSLog(@"image is :::%@",imagename);

            //  UIImage *blockimg=[[UIImage alloc]init ];

            UIImage * blockImage = [UIImage imageNamed:[images objectAtIndex:k]];

            NSLog(@"block image is %@",blockimg);
            TouchImageView * tiv = [[TouchImageView alloc] initWithFrame:blockFrame];
            [[tiv internal] setImage:blockimg];
            [self.view addSubview:[tiv autorelease]];
            k=k+1;
        }
    }

此处图像未添加到块图像中。请给我解决方案。

使用这个，请使用 NSArray

  NSArray *images = [NSArray arrayWithObjects:[UIImage imageNamed:@"item1.jpg"], 
                                 [UIImage imageNamed:@"item1.jpg"],
                             [UIImage imageNamed:@"item1.jpg"],
                             [UIImage imageNamed:@"item1.jpg"], 
                             [UIImage imageNamed:@"item1.jpg"],
                             [UIImage imageNamed:@"item1.jpg"], 
                             [UIImage imageNamed:@"item1.jpg"],nil];

并删除此代码

NSString *imagename=[[NSString alloc]init];
            imagename=[images objectAtIndex:k];
NSLog(@"image is :::%@",imagename);

，然后再次检查断点
