我目前正在使用下面的代码为我的分段tableView
呈现视图- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
UIView *headerView = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.bounds.size.width, 30)] autorelease];
headerView.backgroundColor = [UIColor colorWithRed:30/255 green:30/255 blue:30/255 alpha:1.0];
headerView.layer.masksToBounds = NO;
headerView.layer.shadowOffset = CGSizeMake(0, 0);
headerView.layer.shadowRadius = 3;
headerView.layer.shadowOpacity = 0.5;
headerView.layer.shouldRasterize = YES;
UIBezierPath *path = [UIBezierPath bezierPathWithRect:CGRectMake(0, headerView.frame.size.height, headerView.frame.size.width, 3)];
headerView.layer.shadowPath = path.CGPath;
UILabel *label = [[[UILabel alloc] initWithFrame:CGRectMake(12, 7, tableView.bounds.size.width - 10, 20)] autorelease];
label.font = [UIFont boldSystemFontOfSize:16];
label.text = header;
label.textColor = [UIColor whiteColor];
label.shadowColor = [UIColor blackColor];
label.shadowOffset = CGSizeMake(0.0f, 1.0f);
label.backgroundColor = [UIColor colorWithRed:30/255 green:30/255 blue:30/255 alpha:1.0];
[headerView addSubview:label];
return headerView;
}
出于某种原因虽然文字被破坏了一点点而且有点扭曲?我已经将它缩小到我在图层上施加的效果,虽然我不确定为什么要这样做?
答案 0 :(得分:2)
我发现您将shouldRasterize
设置为YES
。设置光栅化比例有帮助吗?只有在使用iPhone 4时才需要这样做。
[[headerView layer] setRasterizationScale:[[UIScreen mainScreen] scale]];
