简单一点：[mutableAttributedString insertAttributedString：@“•\ t” atIndex：0]；

难点。遵循以下内容。（这是从一个较大的项目中摘录的，但可能会为您提供一个不错的开始。）

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"];

CTTextAlignment alignment = kCTLeftTextAlignment;
CGFloat paragraphSpacing = 0.0;
CGFloat paragraphSpacingBefore = 0.0;
CGFloat firstLineHeadIndent = 15.0;
CGFloat headIndent = 30.0;

CGFloat firstTabStop = 15.0; // width of your indent
CGFloat lineSpacing = 0.45;

CTTextTabRef tabArray[] = { CTTextTabCreate(0, firstTabStop, NULL) };

CFArrayRef tabStops = CFArrayCreate( kCFAllocatorDefault, (const void**) tabArray, 1, &kCFTypeArrayCallBacks );
CFRelease(tabArray[0]);

CTParagraphStyleSetting altSettings[] = 
{
    { kCTParagraphStyleSpecifierLineSpacing, sizeof(CGFloat), &lineSpacing},
    { kCTParagraphStyleSpecifierAlignment, sizeof(CTTextAlignment), &alignment},
    { kCTParagraphStyleSpecifierFirstLineHeadIndent, sizeof(CGFloat), &firstLineHeadIndent},
    { kCTParagraphStyleSpecifierHeadIndent, sizeof(CGFloat), &headIndent},
    { kCTParagraphStyleSpecifierTabStops, sizeof(CFArrayRef), &tabStops},
    { kCTParagraphStyleSpecifierParagraphSpacing, sizeof(CGFloat), &paragraphSpacing},
    { kCTParagraphStyleSpecifierParagraphSpacingBefore, sizeof(CGFloat), &paragraphSpacingBefore}
};

CTParagraphStyleRef style;
style = CTParagraphStyleCreate( altSettings, sizeof(altSettings) / sizeof(CTParagraphStyleSetting) );

if ( style == NULL )
{
    NSLog(@"*** Unable To Create CTParagraphStyle in apply paragraph formatting" );
    return;
}

[string addAttributes:[NSDictionary dictionaryWithObjectsAndKeys:(NSObject*)style,(NSString*) kCTParagraphStyleAttributeName, nil] range:NSMakeRange(0,[string length])];

CFRelease(tabStops);
CFRelease(style);

您需要包括CoreText框架，然后导入CoreText / CoreText.h
