我有一个包含图像URL的数组,我想用这些URL创建一个图像视图(现在使用循环)。
但我没有想到,如何用阵列中的URL进行图像视图希望有人会澄清一下
int x = 0;
for(int i = 0; i <imagearry.count; i ++){
NSDictionary *dict = [imagearry objectAtIndex:i];
NSLog(@"%@",[dict objectForKey:@"img_url"]);
NSString *filePath [NSHomeDirectory()stringByAppendingPathComponent:@"/Library/Caches"];
stringarry = [[imagearry objectAtIndex:i] objectForKey:@"img_url"];
int x = 0;
imageView.image = [UIImage imageNamed:[stringarry objectAtIndex:0]];
for(int i=0; i < [stringarry count]; i++)
{
UIImageView *img = [[UIImageView alloc] init];
img.bounds = CGRectMake(10, 10, 50, 50);
img.frame = CGRectMake(5+x, 0, 160, 110);
NSLog(@"image: %@",[stringarry objectAtIndex:i]);
img.image = [UIImage imageNamed:[stringarry objectAtIndex:i]];
[stringarry insertObject:img atIndex:i];
[scrollView addSubview:[stringarry objectAtIndex:i]];
x += 170;
uiimageView没有从URL显示图像的属性。 您可能必须以NSDATA格式下载它,然后转换为
UIImage
.INSTEAD查看AsyncimageView并存储实例 数组中的AsyncimageView。
检查此链接:asyncimageView
您必须使用imageWithData
而不是imageNamed
:
NSURL * url = [NSURL fileURLWithPath:[filePath stringByAppendingPathComponent:[stringarry objectAtIndex:i]]];
[UIImage imageWithData:[NSData dataWithContentsOfURL:url]];
