[英]Why my UITableView not smooth when scroll first time?
我的表格視圖單元格具有四個標簽。 第一次滾動時,表視圖不平滑。 在所有單元格顯示一次之后,滾動是如此順利,沒有問題。 所以我認為問題在於第一次加載一個單元的速度。
我有重用單元,但問題沒有解決。 請幫我! 非常感謝!
這是我的代碼:
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *MyIdentifier = @"MyIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier];
if (cell == nil) {
NSArray *views = [[NSBundle mainBundle] loadNibNamed:@"ForumListTableViewCell" owner:self options:nil];
cell = [views objectAtIndex:0];
}
NSDictionary *cate = [_forums objectAtIndex:indexPath.section];
NSArray *forumsInCate = [cate objectForKey:@"forums"];
NSDictionary *forumInfo = [forumsInCate objectAtIndex:indexPath.row];
// title1
UILabel *forumTitleLabel = (UILabel *)[cell viewWithTag:1];
forumTitleLabel.text = [forumInfo objectForKey:@"name"];
// master
UILabel *masterLabel = (UILabel *)[cell viewWithTag:2];
NSString *master = [forumInfo objectForKey:@"moderators"];
masterLabel.text = master;
// title2
UILabel *threadTitleLabel = (UILabel *)[cell viewWithTag:3];
NSString *lastPostTitle;
NSDictionary *lastPostInfo = [forumInfo objectForKey:@"lastpost"];
lastPostTitle = [lastPostInfo objectForKey:@"subject"];
threadTitleLabel.text = lastPostTitle;
// author
UILabel *authorLabel = (UILabel *)[cell viewWithTag:4];
authorLabel.text = [NSString stringWithFormat:@"%@ / %@",
[forumInfo objectForKey:@"threads"],
[forumInfo objectForKey:@"posts"]
];
return cell;
}
NSArray *views = [[NSBundle mainBundle] loadNibNamed:@"ForumListTableViewCell" owner:self options:nil];
在.h上
NSArray *views;
在.m上
-(void)viewDidLoad
{
[super viewDidLoad];
views = [[NSBundle mainBundle] loadNibNamed:@"ForumListTableViewCell" owner:self options:nil];
}
- (void)dealloc
{
//--- other object ----
[views release];
[super dealloc];
}
