問題描述：
下面的代碼是用來設置tableView頭標題，默認的text是AlignmentLeft。怎麼設置為AlignmentCenter？
[plain]
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
if(section==0){
return NSLocalizedString(@"more_titlehead_one", nil);
}else if (section==1){
return NSLocalizedString(@"more_titlehead_two", nil);
}else{
return NSLocalizedString(@"more_titlehead_three", nil);
}
}
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
if(section==0){
return NSLocalizedString(@"more_titlehead_one", nil);
}else if (section==1){
return NSLocalizedString(@"more_titlehead_two", nil);
}else{
return NSLocalizedString(@"more_titlehead_three", nil);
}
}
解決方案：
試試如下：
[plain]
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
UILabel * sectionHeader = [[[UILabel alloc] initWithFrame:CGRectZero] autorelease];
sectionHeader.backgroundColor = [UIColor clearColor];
sectionHeader.textAlignment = UITextAlignmentCenter;
sectionHeader.font = [UIFont boldSystemFontOfSize:10];
sectionHeader.textColor = [UIColor whiteColor];
if(section == 0)
{
sectionHeader.text = @"TITLE ONE";
}
else if(section == 1)
{
sectionHeader.text = @"TITLE TWO";
}
else
{
sectionHeader.text = @"TITLE OTHER";
}
return sectionHeader;
}
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
UILabel * sectionHeader = [[[UILabel alloc] initWithFrame:CGRectZero] autorelease];
sectionHeader.backgroundColor = [UIColor clearColor];
sectionHeader.textAlignment = UITextAlignmentCenter;
sectionHeader.font = [UIFont boldSystemFontOfSize:10];
sectionHeader.textColor = [UIColor whiteColor];
if(section == 0)
{
sectionHeader.text = @"TITLE ONE";
}
else if(section == 1)
{
sectionHeader.text = @"TITLE TWO";
}
else
{
sectionHeader.text = @"TITLE OTHER";
}
return sectionHeader;
}
設置標題的默認高度：
[plain]
- (CGFloat)tableView:(UITableView *)tableViewheightForHeaderInSection:(NSInteger)section {
if(section == 0)
{
return 20.0;
}
else if(section == 1)
{
return 20.0;
}
else
{
return 20.0;
}
}
