imageview如何固定宽度（例如都是320），而高度随真实图片的比例来设定

原来如此简单，哪怕是读取的是网络中的图片也是这样的：

static NSString *CellIdentifier =@"Cell";

CHCustomDetailCell *cell = (CHCustomDetailCell *)[tableViewDemodequeueReusableCellWithIdentifier:CellIdentifier];

if (cell == nil)

{

cell = (CHCustomDetailCell *)[[[CHCustomDetailCellalloc] initWithStyle: UITableViewCellStyleDefaultreuseIdentifier:CellIdentifier] autorelease];

}

cell.cusDetailLabel.text =@"荷叶烧肉@烤肉季限时半价";

cell.cusDetailImagView.image =nil;

GCCDetailObject *object = [[GCCategoryDetailMgrShareInstanceSearchMgr].cdArrayobjectAtIndex:indexPath.row];

NSURL *url = [NSURLURLWithString:object.cImage];

if (cell.cusDetailImagView.image ==nil) {

cell.cusDetailImagView.image = [UIImageimageWithData:[NSData dataWithContentsOfURL:url]];; //这个即是读取的网络图片，本地图片就更不用说了

}

CGFloat hei = cell.cusDetailImagView.image.size.height;

CGFloat wid = cell.cusDetailImagView.image.size.width;

CGFloat zhenshi = (320 * hei / wid);

cell.cusDetailImagView.frame =CGRectMake(0, 0,320, zhenshi);

cell.cusDetailLabel.frame =CGRectMake(0, zhenshi - 60, 320, 60);

[cell setFrame:CGRectMake(0,0, 320, zhenshi)];

return cell;
