I download some images using an NSThread. When all the images are downloaded, I have to put them in cell.myimageview. Give me the solution for setting an image in a user-defined method.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"Cell";
TableCell *cell = (TableCell *)[TableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[TableCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
}
NSString *bedsbaths=[NSString stringWithFormat:@"Beds:%@ Baths:%@",[[AppDeleget.statuses valueForKey:@"beds"] objectAtIndex:indexPath.row],[[AppDeleget.statuses valueForKey:@"baths"] objectAtIndex:indexPath.row]];
cell.mlsno.text=[[AppDeleget.statuses valueForKey:@"mlsno"] objectAtIndex:indexPath.row];
cell.price.text=[[AppDeleget.statuses valueForKey:@"price"] objectAtIndex:indexPath.row];
cell.address.text=[[AppDeleget.statuses valueForKey:@"address"] objectAtIndex:indexPath.row];
cell.bedsbaths.text=bedsbaths;
cell.accessoryType=UITableViewCellAccessoryDetailDisclosureButton;
return cell;
}
-(void)LoadImage
{
for(int x=0;x<[ListPhotos count];x++)
{
NSData *imageData =[ListPhotos objectAtIndex:x];
id path = imageData;
NSURL *url = [NSURL URLWithString:path];
NSLog(@"%@",url);
NSData *data = [NSData dataWithContentsOfURL:url];
开发者_运维技巧 UIImage *img = [[UIImage alloc] initWithData:data];
[self performSelectorOnMainThread:@selector(downloadDone:) withObject:img waitUntilDone:NO];
}
}
-(void)downloadDone:(UIImage*)img {
// I have to set the cell here. How?
cell.myimageView.image=img
}
In -(void)LoadImage
Store the img in a NSArray.
In - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
, code as
cell.myimageView.image=[imgArray objectAtIndex:indexPath.row];
Assign the delegate and datasource of tableview as,
-(void)downloadDone:(UIImage*)img {
self.tableView.delegate=self;
self.tableView.datasource=self;
}
