Answer 1

这是一种适用于 iOS6 的更现代的方法:

NSMutableAttributedString * string = [[NSMutableAttributedString alloc] initWithString:@"•\texample bullet fill out the text to check what happens on the second line and make sure it is lining up OK"];

NSMutableParagraphStyle *paragraphStyle;
paragraphStyle = [[NSParagraphStyle defaultParagraphStyle] mutableCopy];
[paragraphStyle setTabStops:@[[[NSTextTab alloc] initWithTextAlignment:NSTextAlignmentLeft location:15 options:nil]]];
[paragraphStyle setDefaultTabInterval:15];
[paragraphStyle setFirstLineHeadIndent:0];
[paragraphStyle setHeadIndent:15];

[string addAttributes:@{NSParagraphStyleAttributeName: paragraphStyle} range:NSMakeRange(0,[string length])];
