我正在尝试在填充真实数据之前创建示例库。
float xAxis = 0;
float mostHeight = self.galleryView.bounds.size.height;
for (int i = 0; i < 5; i++) {
//getImage from url
UIImage* myImage = [UIImage imageWithData:
[NSData dataWithContentsOfURL:
[NSURL URLWithString: @"http://4.bp.blogspot.com/-M9k3fhlUwmE/TdYgxL97xMI/AAAAAAAAAY8/_r45zbAm1p0/s1600/CARTOON_Cat-full.jpg"]]];
myImage = [[MyMath sharedMySingleton] imageWithImage:myImage convertToSize:CGSizeMake(mostHeight - 10, mostHeight - 10)];
//set image
UIImageView *rview= [[UIImageView alloc] initWithImage:myImage];
/*adding the view to your scrollview*/
[self.galleryView addSubview:rview];
xAxis += myImage.size.width + 20;
}
//set scrolling area
self.galleryView.contentSize = CGSizeMake(xAxis, mostHeight);
galleryView 是来自 xib 的 UIScrollView。在这里,我试图将 5 张相同的图片填充到图库,但它只填充了一张和之后的空格(因为 xAxis 编号)。我做错了什么?
PS我是iPhone sdk的新手,所以不要评判我
