我正在使用
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
customView = [[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, 320.0, 24.0)];//custom view
// create the button object
headerLabel = [[UILabel alloc]initWithFrame:CGRectMake(10, 3, tableView.bounds.size.width, 18)];//header label
headerLabel.backgroundColor = [UIColor colorWithPatternImage: [UIImage imageWithContentsOfFile: [[NSBundle mainBundle] pathForResource: @"section" ofType: @"png"]]];
customView.backgroundColor = [UIColor colorWithPatternImage: [UIImage imageWithContentsOfFile: [[NSBundle mainBundle] pathForResource: @"section" ofType: @"png"]]];
headerLabel.textColor = [UIColor whiteColor];//text color of header label
headerLabel.font = [UIFont fontWithName:@"HelveticaNeue" size:15];//font of header label
headerLabel.font = [UIFont boldSystemFontOfSize:15];
headerLabel.frame = CGRectMake(0.0, 0.0, 320.0, 24.0);//frame of header label
if(searching)//checking searching {
headerLabel.text = @" Search Results";//searching results as a text of header label
}
else {
if(section == 0)//checking which section is chosen {
headerLabel.text = @" Sponsored";//sponsored as header label
}
else {
headerLabel.text = @" Unsponsored";//un sponsored as header label
}
}
if(searching)//checking searching {
headerLabel.text = @" Sök resultat";//sok resultant text as a header label
}
else {
if(section == 0)//checking which section is chosen {
headerLabel.text = @" Sponsrade";//sponsorade as text of header label
}
else {
headerLabel.text = @" Un Sponsrade";//usponsrade as text of header label
}
}
[customView addSubview:headerLabel];//header label as a subview
//NSLog(@"endOfviewForHeaderInSection");
//[headerLabel release];
return customView;//returning custom view
[customView release];
//NSLog(@"endOfviewForHeaderInSection");
}
在表视图的头部分中，在两个部分中划分表，当我在上下滚动表视图时，内存分配增加非常快，但是在头部分上没有使用上面提到的代码，没有内存分配和应用程序工作得很好，但是需要在头部分上使用上面的代码，我不能从头文件中删除代码，我也想减少内存分配。还有没有其他方法可以解决这个问题呢？。
提前谢谢。
