我试图用来NSTextList在多行显示数字列表,NSTextField但它没有按预期工作.

使用的示例代码是:

- (IBAction)displayResult:(id)sender
{
    NSTextList *list = [[NSTextList alloc] initWithMarkerFormat:self.markerFormat options:1]; // {Decimal} passed as marker format
    NSMutableParagraphStyle *paragraph = [[NSParagraphStyle defaultParagraphStyle] mutableCopy];
    [paragraph setTextLists:[NSArray arrayWithObject:list]];
    [list release];
    NSDictionary *attributes = [NSDictionary dictionaryWithObjectsAndKeys:paragraph, NSParagraphStyleAttributeName, nil];
    NSAttributedString *attrString = [[NSAttributedString alloc] initWithString:self.inputString attributes:attributes] ; // input string is- George \n Thomas \n Ashok
    [self setOutputString:attrString]; 
    [attrString release];
    [paragraph release];
}

输入是 -

George 

Thomas 

Ashok

输出应该是 -

1 George

2 Thomas

3 Ashok

但它显示的输出是 -

George …
