GMGridView
をリフレッシュする必要があるたびに、すべてのセルが再作成されるため、時間がかかります。iOS GMGridView GMGridViewCellセルを再利用する方法は?
再利用識別子をGMGridViewCell
に割り当てる方法はありますか、何とか再利用可能であることを確認してください。
ここでは、すべての表示可能なビューを毎回再作成するコードを示します。
- (GMGridViewCell *)GMGridView:(GMGridView *)gridView cellForItemAtIndex:(NSInteger)index
{
NSLog(@"Creating view indx %d", index);
CGSize size = [self sizeForItemsInGMGridView:gridView];
GMGridViewCell *cell = [gridView dequeueReusableCell];
if (!cell)
{
cell = [[GMGridViewCell alloc] init];
cell.deleteButtonIcon = [UIImage imageNamed:@"close_x.png"];
cell.deleteButtonOffset = CGPointMake(30, -20);
UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 57, 57)];
cell.userData = [[IconFile allObjects] objectAtIndex:index];
UIImageView* imageView = [[UIImageView alloc] initWithFrame:view.frame];
NSIndexPath* indexPath = [NSIndexPath indexPathForRow:index inSection:0];
IconFile* iconFile_ = [self.fetchedResultsController objectAtIndexPath:indexPath];
// imageView.image = [UIImage imageNamed:@"retina_114x114_1.png"];
imageView.image = [UIImage imageWithData:iconFile_.image114];
[view addSubview:imageView];
imageView.center = view.center;
imageView.layer.masksToBounds = YES;
imageView.layer.cornerRadius = 9;
view.backgroundColor = [UIColor clearColor];
// view.layer.masksToBounds = YES;
// view.layer.cornerRadius = 9;
view.layer.shadowColor = [UIColor grayColor].CGColor;
view.layer.shadowOffset = CGSizeMake(5, 5);
view.layer.shadowPath = [UIBezierPath bezierPathWithRect:view.bounds].CGPath;
view.layer.shadowRadius = 9;
ShadowLabel *label = [[ShadowLabel alloc] initWithFrame:CGRectMake(0,0,72,21)];
label.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
// label.text = (NSString *)[_data objectAtIndex:index];
label.text = iconFile.springBoardName;
label.layer.shadowPath = [UIBezierPath bezierPathWithRect:label.bounds].CGPath;
label.layer.shadowRadius = 9;
label.textAlignment = UITextAlignmentCenter;
label.backgroundColor = [UIColor clearColor];
label.textColor = [UIColor whiteColor];
label.font = [UIFont boldSystemFontOfSize:11];
[view addSubview:label];
label.center = CGPointMake(size.width/2, 60);
cell.contentView = view;
}else{
// [[cell.contentView subviews] makeObjectsPerformSelector:@selector(removeFromSuperview)];
//
// UILabel *label = [[UILabel alloc] initWithFrame:cell.contentView.bounds];
// label.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
// label.text = (NSString *)[_data objectAtIndex:index];
// label.textAlignment = UITextAlignmentCenter;
// label.backgroundColor = [UIColor clearColor];
// label.textColor = [UIColor blackColor];
// label.font = [UIFont boldSystemFontOfSize:20];
// [cell.contentView addSubview:label];
}
return cell;
}
