寫了一個循環來UIImageView批量在創建圖片。我做了如下操作:
UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(38, 9, 90, 280)];
int numberOfImages = 9;
CGFloat currentY = 0.5f;
for (int i=1; i <= numberOfImages; i++) {
NSString *imageName = [NSString stringWithFormat:@"img0%d.jpg",i];
UIImage *image = [UIImage imageNamed:imageName];
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
imageView.frame = CGRectMake(2, 15, 87, imageView.frame.size.height - 20);
CGRect rect = imageView.frame;
rect.origin.y = currentY;
imageView.frame = rect;
currentY += imageView.frame.size.height;
[scrollView addSubview:imageView];
}
scrollView.contentSize = CGSizeMake(87,currentY);
[self.view addSubview:scrollView];
需要在每個圖片之間添加空白區域,應該怎麼實現?
添加到currentY中:
currentY += imageView.frame.size.height + 12.0f;
