NSMutableAttributedString垂直对齐

Question

我有一个文本的椭圆路径。对于填充路径，我使用了NSMutableAttributedString：

UIFont *font = [UIFont fontWithName:@"font name" size:15];
NSMutableParagraphStyle *mutParaStyle=[[NSMutableParagraphStyle alloc] init];

[mutParaStyle setAlignment:NSTextAlignmentCenter];
[mutParaStyle setLineBreakMode:NSLineBreakByWordWrapping];

NSDictionary *attrsDictionary = [NSDictionary dictionaryWithObjectsAndKeys:font
                                 ,NSFontAttributeName,mutParaStyle ,NSParagraphStyleAttributeName,nil]; 

NSMutableAttributedString  *strText = [[NSMutableAttributedString alloc] initWithString:text attributes:attrsDictionary];

但这只适用于水平文本对齐。如何应用垂直对齐？

我有这样的结果：

但我需要这个：

但我已经尝试了垂直它是工作很好的我，下面是截图让我知道如果我错了，也是下面的代码附件：--

NSString *allTheText = [tv string];
NSFont *font = [NSFont fontWithName:@"Helvetica" size:24];
NSMutableParagraphStyle *mutParaStyle=[[NSMutableParagraphStyle alloc] init];

[mutParaStyle setAlignment:kCTTextAlignmentRight];
[mutParaStyle setLineBreakMode:NSLineBreakByWordWrapping];

NSDictionary *attrsDictionary = [NSDictionary dictionaryWithObjectsAndKeys:font
                                 ,NSFontAttributeName,mutParaStyle ,NSParagraphStyleAttributeName,nil];

NSMutableAttributedString  *strText = [[NSMutableAttributedString alloc] initWithString:allTheText attributes:attrsDictionary];
[tv .textStorage appendAttributedString:strText];
