iOS上有NSTextList的等价物吗？
在OSX上，我可以

NSTextList *list = [[NSTextList alloc] initWithMarkerFormat:@"square" options:0];
NSMutableParagraphStyle *paragraph = [[NSParagraphStyle defaultParagraphStyle] mutableCopy];
[paragraph setTextLists:[NSArray arrayWithObject:list]];
NSTextTab *t1 = [[NSTextTab alloc] initWithType:0 location:11.0f];
NSTextTab *t2 = [[NSTextTab alloc] initWithType:0 location:36.0f];
[paragraph setTabStops:[NSArray arrayWithObjects:t1, t2, nil]];
NSDictionary *attributes = [NSDictionary dictionaryWithObjectsAndKeys:paragraph, NSParagraphStyleAttributeName, nil];
NSString *string = @"\t▪\tList item 1\n\t▪\tList item 2\n\t▪\tList item 3";
NSMutableAttributedString *attrString = [[NSMutableAttributedString alloc] initWithString:string attributes:attributes];

但iOS没有替代方案，因为所有解决方案都不正确
