static NSString *CellIdentifier = @"TweetListUserName";
CustomTableViewCell *cell = (CustomTableViewCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[CustomTableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier]autorelease] ;
}
一个单元格,使用下面的代码来设置一个节头的小区标识:
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
UIView* customView = [[[UIView alloc] initWithFrame:CGRectMake(0.0, -4.0, 320.0, 67.0)]autorelease];
[customView setOpaque:YES];
UIImageView *image = [[UIImageView alloc] initWithFrame:CGRectMake(-2.0, -4.0, 328.0, 67.0)];
[image setImage:[UIImage imageNamed:@"header-msg.png"]];
[image setOpaque:YES];
[customView addSubview:image];
UILabel *label1 =[[UILabel alloc] initWithFrame:CGRectMake(10, 5, 100, 12)];
label1.text [email protected]"TWEETS MATCHING:";
label1.textAlignment=UITextAlignmentLeft;
[label1 setTextColor:[UIColor grayColor]];
[label1 setFont:[UIFont fontWithName:@"Helvetica" size:9]];;
[label1 setBackgroundColor:[UIColor clearColor]];
[customView addSubview:label1];
[label1 release];
UILabel *label2 =[[UILabel alloc] initWithFrame:CGRectMake(10, 6, 315, 50)];
label2.text =usernametag;
label2.textAlignment=UITextAlignmentLeft;
[label2 setTextColor:[UIColor blackColor]];
[label2 setFont:[UIFont fontWithName:@"Helvetica-Bold" size:20]];
[label2 setBackgroundColor:[UIColor clearColor]];
[customView addSubview:label2];
[label2 release];
return customView;
}
然而,当我快速滚动表头几乎在所有情况下闪烁。我怎样才能防止这种闪烁?
实际上没有在代码中提到,但我释放自定义视图 – crystal 2009-12-24 06:13:25
这不是该单元格闪烁标题的原因。我知道这是一个古老的问题......但现在发生在我身上。 – Jann 2011-08-10 15:43:27
你是否在重复调用的任何地方调用[tableView reloadData]? – RickiG 2011-08-11 09:46:24
