富文本的所有屬性
NSFontAttributeName 字號(hào) UIFont 默認(rèn)12
NSParagraphStyleAttributeName 段落樣式 NSParagraphStyle
NSForegroundColorAttributeName 前景色 UIColor
NSBackgroundColorAttributeName 背景色 UIColor
NSObliquenessAttributeName 字體傾斜 NSNumber
NSExpansionAttributeName 字體加粗 NSNumber 比例 0就是不變 1增加一倍
NSKernAttributeName 字間距 CGFloat
NSUnderlineStyleAttributeName 下劃線 1或0
NSUnderlineColorAttributeName 下劃線顏色 UIColor
NSStrikethroughStyleAttributeName 刪除線 1或0
NSStrikethroughColorAttributeName 刪除線顏色 UIColor
NSStrokeColorAttributeName same as ForegroundColor UIColor
NSStrokeWidthAttributeName 字體描邊 CGFloat
NSLigatureAttributeName 連筆字 沒看出效果 1或0
NSShadowAttributeName 陰影 NSShawdow
NSTextEffectAttributeName 設(shè)置文本特殊效果,目前只有圖版印刷效果可用 NSString
NSAttachmentAttributeName 設(shè)置文本附件,常用插入圖片 NSTextAttachment
NSLinkAttributeName 鏈接 NSURL (preferred) or NSString
NSBaselineOffsetAttributeName 基準(zhǔn)線偏移 NSNumber
NSWritingDirectionAttributeName 文字方向 分別代表不同的文字出現(xiàn)方向等等，我想你一定用不到它 - - @[@(1),@(2)]
NSVerticalGlyphFormAttributeName 水平或者豎直文本 在iOS沒卵用，不支持豎版 1豎直 0水平
段落樣式
段落樣式主要改行距、段距、首行縮進(jìn)、最大最小行高、多倍行距等十幾個(gè)屬性
NSMutableParagraphStyle *muParagraph = [[NSMutableParagraphStyle alloc]init];
muParagraph.lineSpacing = 10; // 行距
muParagraph.paragraphSpacing = 20; // 段距
muParagraph.firstLineHeadIndent = 30; // 首行縮進(jìn)
陰影
NSShadow *shadow = [[NSShadow alloc]init];
shadow.shadowOffset = CGSizeMake(2, 2);
shadow.shadowColor = [UIColor orangeColor];
shadow.shadowBlurRadius = 1;
我的富文本代碼，可以copy過(guò)去直接試
- (void)viewDidLoad {
[super viewDidLoad];
self.view.backgroundColor = [UIColor grayColor];
[self.view addSubview:self.attTV];
