[mutableAttriteStr appendAttributedString:attributeStr2];
[mutableAttriteStr appendAttributedString:attributeStr5];
self.label1.attributedText = mutableAttriteStr;

表示使用默認(rèn)的連體字符。2表示使用所有連體符號(hào)。默認(rèn)值為 1（注意，iOS 不支持值
為 2）
// 連體藝術(shù)字，不是每個(gè)都能連起的，f和l f和i就可以，其他各位可以自己去試試
self.label2.attributedText = [[NSAttributedString alloc] initWithString:@"flush and fily" attributes:@{NSLigatureAttributeName : [NSNumber numberWithInt:1],NSFontAttributeName : [UIFont fontWithName:@"futura" size:30]}];
NSMutableAttributedString *mutableAttributeStr2 = [[NSMutableAttributedString alloc] init];

NSMutableAttributedString *mutableAttributeStr2 = [[NSMutableAttributedString alloc] init];
NSAttributedString *string6 = [[NSAttributedString alloc] initWithString:@"ABCDE " attributes:@{NSKernAttributeName : [NSNumber numberWithInt:-3],NSForegroundColorAttributeName : [UIColor redColor]}];
NSAttributedString *string7 = [[NSAttributedString alloc] initWithString:@"FGHIJ " attributes:@{NSKernAttributeName : [NSNumber numberWithInt:0],NSForegroundColorAttributeName : [UIColor yellowColor]}];

NSMutableAttributedString *mutableAttributeStr3 = [[NSMutableAttributedString alloc] init];
NSAttributedString *string9 = [[NSAttributedString alloc] initWithString:@"只要998 " attributes:@{NSStrikethroughStyleAttributeName : @(NSUnderlineStyleSingle),NSStrikethroughColorAttributeName : [UIColor redColor]}];

[mutableAttributeStr3 appendAttributedString:string9];
[mutableAttributeStr3 appendAttributedString:string10];
[mutableAttributeStr3 appendAttributedString:string11];
self.label4.attributedText = mutableAttributeStr3;
7.NSUnderlineStyleAttributeName 和 NSUnderlineColorAttributeName
給文字加下劃線和更換下劃線顏色，屬性和上面的刪除線都是一樣用的
20160807122021815.png
NSMutableAttributedString *mutableAttributeStr4 = [[NSMutableAttributedString alloc] init];
NSAttributedString *string12 = [[NSAttributedString alloc] initWithString:@"只要888 " attributes:@{NSUnderlineStyleAttributeName : @(NSUnderlineStyleSingle),NSUnderlineColorAttributeName : [UIColor redColor]}];

[mutableAttributeStr4 appendAttributedString:string13];
[mutableAttributeStr4 appendAttributedString:string14];
self.label5.attributedText = mutableAttributeStr4;
8.NSStrokeWidthAttributeName 和 NSStrokeColorAttributeName
設(shè)置文字描邊顏色，需要和NSStrokeWidthAttributeName設(shè)置描邊寬度，這樣就能使文字空心.
NSStrokeWidthAttributeName 這個(gè)屬性所對(duì)應(yīng)的值是一個(gè) NSNumber 對(duì)象(小數(shù))。該值改變筆畫(huà)寬度（相對(duì)于字體 size 的百分比），負(fù)值填充效果，正值中空效果，默認(rèn)為 0，即不改變。正數(shù)只改變描邊寬度。負(fù)數(shù)同時(shí)改變文字的描邊和填充寬度。例如，對(duì)于常見(jiàn)的空心字，這個(gè)值通常為 3.0。
同時(shí)設(shè)置了空心的兩個(gè)屬性，并且 NSStrokeWidthAttributeName 屬性設(shè)置為整數(shù)，文字前景色就無(wú)效果了
NSMutableAttributedString *mutableAttributeStr5 = [[NSMutableAttributedString alloc] init];
// 如果這個(gè)stroke的width正數(shù)的時(shí)候，字體就中空了，那么前景色就設(shè)置無(wú)效了
NSAttributedString *string15 = [[NSAttributedString alloc] initWithString:@"HELLO " attributes:@{NSStrokeWidthAttributeName : @(5),NSStrokeColorAttributeName : [UIColor yellowColor],NSFontAttributeName : [UIFont boldSystemFontOfSize:30],NSForegroundColorAttributeName : [UIColor redColor]}];
NSAttributedString *string16 = [[NSAttributedString alloc] initWithString:@"YUKD " attributes:@{NSStrokeWidthAttributeName : @(0),NSStrokeColorAttributeName : [UIColor redColor],NSFontAttributeName : [UIFont boldSystemFontOfSize:30]}];
NSAttributedString *string17 = [[NSAttributedString alloc] initWithString:@"GOOGLE" attributes:@{NSStrokeWidthAttributeName : @(-5),NSStrokeColorAttributeName : [UIColor greenColor],NSFontAttributeName : [UIFont boldSystemFontOfSize:30],NSForegroundColorAttributeName : [UIColor lightGrayColor]}];
[mutableAttributeStr5 appendAttributedString:string15];
[mutableAttributeStr5 appendAttributedString:string16];
[mutableAttributeStr5 appendAttributedString:string17];
self.label6.attributedText = mutableAttributeStr5;
9.NSShadowAttributeName
設(shè)置文字陰影，取值為NSShadow對(duì)象
20160807123121931.png
// 設(shè)置陰影
NSShadow *shadow = [[NSShadow alloc] init];
shadow.shadowBlurRadius = 5.0f; // 模糊度
shadow.shadowColor = [UIColor blueColor];
shadow.shadowOffset = CGSizeMake(1, 5);
NSAttributedString *string20 = [[NSAttributedString alloc] initWithString:@"HELLO_HALY_璟" attributes:@{NSFontAttributeName : [UIFont boldSystemFontOfSize:30],NSForegroundColorAttributeName : [UIColor redColor],NSShadowAttributeName : shadow}];
self.label7.attributedText = string20;
10.NSTextEffectAttributeNam
NSTextEffectAttributeName //設(shè)置文本特殊效果，取值為NSString類型，目前只有一個(gè)可用效果 NSTextEffectLetterpressStyle（凸版印刷效果）
20160807123246574.png
// 文本印刷，我也不知道是什么鬼
// 設(shè)置陰影
NSAttributedString *string21 = [[NSAttributedString alloc] initWithString:@"HELLO_HALY_璟" attributes:@{NSFontAttributeName : [UIFont boldSystemFontOfSize:30],NSForegroundColorAttributeName : [UIColor redColor],NSShadowAttributeName : shadow,NSTextEffectAttributeName : NSTextEffectLetterpressStyle}];
self.label8.attributedText = string21;
11.NSBaselineOffsetAttributeName
文字基線偏移,想要達(dá)到以下圖片的效果，就要設(shè)置需要的文字偏移，正數(shù)上移，負(fù)數(shù)下移
20160807123730298.png
// 設(shè)置文本的基線 負(fù)數(shù)向下 正數(shù)向上 0不變
UIFont *bigFont = [UIFont boldSystemFontOfSize:36];
UIFont *smallFont = [UIFont boldSystemFontOfSize:bigFont.pointSize / 2];
CGFloat capHeight = bigFont.pointSize - smallFont.pointSize;
NSMutableAttributedString *attributeString6 = [[NSMutableAttributedString alloc] init];
NSAttributedString *string22 = [[NSAttributedString alloc] initWithString:@"￥" attributes:@{NSFontAttributeName : smallFont,NSForegroundColorAttributeName : [UIColor blackColor],NSBaselineOffsetAttributeName : @(0)}];

NSAttributedString *string26 = [[NSAttributedString alloc] initWithString:@"0" attributes:@{NSFontAttributeName : bigFont,NSForegroundColorAttributeName : [UIColor redColor],NSBaselineOffsetAttributeName : @(0)}];
NSAttributedString *string27 = [[NSAttributedString alloc] initWithString:@".09" attributes:@{NSFontAttributeName : smallFont,NSForegroundColorAttributeName : [UIColor blackColor],NSBaselineOffsetAttributeName : @(capHeight - 5)}];
[attributeString6 appendAttributedString:string22];
[attributeString6 appendAttributedString:string23];
[attributeString6 appendAttributedString:string24];
[attributeString6 appendAttributedString:string28];
[attributeString6 appendAttributedString:string25];
[attributeString6 appendAttributedString:string26];
[attributeString6 appendAttributedString:string27];
self.label9.attributedText = attributeString6;
NSMutableAttributedString *attributeString7 = [[NSMutableAttributedString alloc] init];
NSAttributedString *string29 = [[NSAttributedString alloc] initWithString:@"Hello " attributes:@{NSFontAttributeName : [UIFont boldSystemFontOfSize:40],NSForegroundColorAttributeName : [UIColor blackColor],NSBaselineOffsetAttributeName : @(0)}];

14.NSVerticalGlyphFormAttributeName
NSVerticalGlyphFormAttributeName 設(shè)置文字排版方向，取值為NSNumber對(duì)象（整數(shù)），0表示橫排文本，1表示豎排文本 在iOS中只支持0
20160807124536918.png
// 說(shuō)明：NSVerticalGlyphFormAttributeName 設(shè)置文字排版方向，取值為NSNumber對(duì)象（整數(shù)），0表示橫排文本，1表示豎排文本 在iOS中只支持0

// NSExpansionAttributeName
// 說(shuō)明：NSExpansionAttributeName 設(shè)置字體的橫向拉伸，取值為NSNumber （float），正值拉伸 ，負(fù)值壓縮
NSMutableAttributedString *mutableAttriteStr = [[NSMutableAttributedString alloc] init];
NSAttributedString *attributeStr1 = [[NSAttributedString alloc] initWithString:@"HeHe_XiXi_mm" attributes:@{NSFontAttributeName :[UIFont boldSystemFontOfSize:30],NSForegroundColorAttributeName : [UIColor redColor],NSShadowAttributeName : shadow,NSObliquenessAttributeName : @(1),NSExpansionAttributeName : @(1),NSVerticalGlyphFormAttributeName : @(1)}];
[mutableAttriteStr appendAttributedString:attributeStr1];
self.label1.attributedText = mutableAttriteStr;
15.NSWritingDirectionAttributeName
文字書(shū)寫(xiě)方向取值為以下組合為例 他是一個(gè)數(shù)組包含NSNumber 一般書(shū)寫(xiě)就是L ---R
那么我們多個(gè)需求也就是從R --- L
The values of the NSNumber objects should be 0, 1, 2, or 3, for LRE, RLE, LRO, or RLO respectively, and combinations of leftToRight and rightToLeft withNSTextWritingDirectionEmbedding or NSTextWritingDirectionOverride
20160807124955094.png
// 文字書(shū)寫(xiě)方向
// The values of the NSNumber objects should be 0, 1, 2, or 3, for LRE, RLE, LRO, or RLO respectively, and combinations of leftToRight and rightToLeft with NSTextWritingDirectionEmbedding or NSTextWritingDirectionOverride, as shown in Table 1.

[attributuStr2 appendAttributedString:string1];
self.label.attributedText = attributuStr2;
16.NSLinkAttributeName
這貨有點(diǎn)奇葩，所以很多人用第三方例如YYLabel來(lái)做，這東西不能在UILabel和UITextField使用，只能用UITextView來(lái)進(jìn)行，實(shí)現(xiàn)他的代理，在代理方法里面進(jìn)行URL跳轉(zhuǎn)
該方法返回YES就能打開(kāi)URL，NO不做任何事情
- (BOOL)textView:(UITextView *)textView shouldInteractWithURL:(NSURL *)URL inRange:(NSRange)characterRange
注：
1.一定要實(shí)現(xiàn)UITextView的代理才能進(jìn)行URL跳轉(zhuǎn)
2.textView的editable屬性修改為NO，在編輯時(shí)不可點(diǎn)擊
20160807130600290.png
// 把 NSLinkAttributeName 屬性單獨(dú)列出來(lái)，是因?yàn)樵?UILabel 和 UITextField 中是無(wú)法使用該屬性的。更準(zhǔn)確點(diǎn)說(shuō)是在UILabel 和 UITextField 中無(wú)法實(shí)現(xiàn)點(diǎn)擊鏈接啟動(dòng)瀏覽器打開(kāi)一個(gè)URL地址，因?yàn)樵诖诉^(guò)程中用到了一個(gè)代理函數(shù)。只能用在 UITextView 中
self.textView.delegate = self;
self.textView.scrollEnabled = NO;
self.textView.editable = NO;
self.textView.textContainer.lineFragmentPadding = 0;
self.textView.textContainerInset = UIEdgeInsetsMake(0, 0, 0, 0);
NSString *str = @" 跳轉(zhuǎn)到宓珂璟的博客";
NSMutableAttributedString *attrStr = [[NSMutableAttributedString alloc]initWithString:str];
[attrStr addAttribute:NSLinkAttributeName value:[NSURL URLWithString:@"http://blog.csdn.net/deft_mkjing"] range:[str rangeOfString:@"宓珂璟的博客"]];
[attrStr addAttribute:NSFontAttributeName value:[UIFont boldSystemFontOfSize:30] range:NSMakeRange(0, str.length)];
self.textView.attributedText = attrStr;
17.NSTextAttachment
設(shè)置文本附件，取值為NSTextAttachment對(duì)象 常用于圖文混排
20160807131107937.png
NSString *words = @"天才";
NSMutableAttributedString *strAtt = [[NSMutableAttributedString alloc] initWithString:words attributes:@{NSFontAttributeName : [UIFont boldSystemFontOfSize:25]}];
NSTextAttachment *attatch = [[NSTextAttachment alloc] initWithData:nil ofType:nil];
attatch.bounds = CGRectMake(0, 0, 40, 30);
attatch.image = [UIImage imageNamed:@"$DCZ2WLN9RWI6JF(Q`P_(NH.jpg"];
NSTextAttachment *attatch1 = [[NSTextAttachment alloc] initWithData:nil ofType:nil];
attatch1.bounds = CGRectMake(0, 0, 50, 30);
attatch1.image = [UIImage imageNamed:@"%5T@J(4WKWSOX2~~PY0{4M0.jpg"];
NSAttributedString *string8 = [NSAttributedString attributedStringWithAttachment:attatch];
NSAttributedString *string9 = [NSAttributedString attributedStringWithAttachment:attatch1];
[strAtt insertAttributedString:string8 atIndex:1];
[strAtt insertAttributedString:string9 atIndex:0];
self.label3.attributedText = strAtt;
基本的就介紹到這里了，上面那些已經(jīng)足夠用了，而且可以任意組合出想要的圖文混排，
如果遇到特殊的需求或者不能滿足的，那么就需要各位去試試往上的第三方富文本了
給個(gè)好用的大家可以試試點(diǎn)擊打開(kāi)鏈接
