我使用圖像url在UITableViewCell上設置圖像,但圖像不會得到負載,除非我滾動UITableView.Here是我一直在使用的代碼,我必須知道SDWeb圖像庫從url下載圖像,但我不想使用任何庫。請告訴我在這做什麼錯誤的目的。在iOS中設置UITableview的細胞圖像
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
// Configure the cell...
NSDictionary *dictCard=[cardsDetailsArray objectAtIndex:indexPath.row];
UILabel *nameLabel = (UILabel *)[cell viewWithTag:10];
UILabel *dateLabel = (UILabel *)[cell viewWithTag:11];
UIImageView *cellImage=(UIImageView *)[cell viewWithTag:0];
CGSize firstSize=CGSizeZero;
if([[dictCard objectForKey:@"orientation"]isEqualToString:@"1"]){
[cellImage setFrame:CGRectMake(0, 0, 75, 68)];
firstSize=CGSizeMake(75,68);
}
if([[dictCard objectForKey:@"orientation"]isEqualToString:@"0"]){
[cellImage setFrame:CGRectMake(0, 0, 107, 72)];
firstSize=CGSizeMake(107,72);
}
[cellImage setBackgroundColor:[UIColor clearColor]];
NSString *string=[dictCard objectForKey:@"email_sent"];
NSArray *items = [string componentsSeparatedByString:@","];
dateLabel.text=[dictCard objectForKey:@"date"];
nameLabel.text=[NSString stringWithFormat:@"Sent to %d People",[items count]];
NSURL* url = [NSURL URLWithString:(NSString *) [dictCard objectForKey:@"card_thumbnail"]];
NSURLRequest* request = [NSURLRequest requestWithURL:url];
[NSURLConnection sendAsynchronousRequest:request
queue:[NSOperationQueue mainQueue]
completionHandler:^(NSURLResponse * response,
NSData * data,
NSError * error) {
if (!error){
UIImage* image = [[UIImage alloc] initWithData:data];
//i am scaling the image here
UIImage *imageScale=[self imageWithImage:image scaledToSize:firstSize];
[cellImage setImage:imageScale];
}
}];
return cell;
}
我還添加[__tableViewDraft reloadData];設置細胞圖像後,但由於這是我的細胞不斷改變其細胞圖像。
可否請您在代碼中進行一些編輯以便更好地瞭解我。謝謝 – ankyy
