在视图中有一个UIScrollView,要显示的图片位于一个数组内,我想要在UIScrollView中显示图片,谢谢。
NSMutableArray *images = [[NSMutableArray alloc ] init];
for (int i = 0; i < 10; i++)
{
NSString *getImagePath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:@"%d/%d.png",b, i]];
UIImage *img = [UIImage imageWithContentsOfFile:getImagePath];
[images addObject:img];
NSLog(@"%@",getImagePath);
imge.image=img;
}

设置UIScrollView的contentSize,然后添加UIImageView到ScrollView。
[self.myScView addSubView:self.imageView];
添加图片到单独的UIImageView。
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
self.scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 320, 460)];
self.scrollView.contentSize = CGSizeMake(320, 465);
self.scrollView.delegate = self;
[self.view addSubview:self.scrollView];
int Y = 0;
// here give you image name is proper so we can access it by for loop.
for (int i = 1; i <= totalNumberOFImage; i++)
{
UIImageView *imageView = [[UIImageView alloc] initWithFrame: CGRectMake(0, Y, 100, 100)] ;
[imageView setImage: [UIImage imageNamed:[NSString stringWithFormat:@"youImageName%d", i]]];
[self.scrollView addSubview: imageView];
Y = Y + imageView.frame.size.height+5;
if(y > 465)
self.scrollView.contentSize = CGSizeMake(320, y);
}
}
