NSMutableParagraphStyle的部分属性:
typedef NS_ENUM(NSInteger, NSLineBreakMode) {/* What to do with long lines */ NSLineBreakByWordWrapping = 0, /* Wrap at word boundaries, default */ NSLineBreakByCharWrapping,/* Wrap at character boundaries */ NSLineBreakByClipping,/* Simply clip */剪掉后面显示不了的部分 NSLineBreakByTruncatingHead,/* Truncate at head of line: "...wxyz" */头部分的内容以……方式省略 NSLineBreakByTruncatingTail,/* Truncate at tail of line: "abcd..." */结尾部分的内容以……方式省略 NSLineBreakByTruncatingMiddle/* Truncate middle of line: "ab...yz" */中间部分的内容以……方式省略 } NS_ENUM_AVAILABLE_IOS(6_0); typedef NS_ENUM(NSInteger, NSWritingDirection) { NSWritingDirectionNatural = -1, // Determines direction using the Unicode Bidi Algorithm rules P2 and P3 NSWritingDirectionLeftToRight = 0, // Left to right writing direction 左到右的书写方向 NSWritingDirectionRightToLeft = 1 // Right to left writing direction 右到左的书写方向 } NS_ENUM_AVAILABLE_IOS(6_0); // NSParagraphStyleAttributeName 段落的风格(设置首行,行间距,对齐方式什么的)看自己需要什么属性,写什么 NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init]; paragraphStyle.lineSpacing = 10;// 字体的行间距 paragraphStyle.firstLineHeadIndent = 20.0f;//首行缩进 paragraphStyle.alignment = NSTextAlignmentJustified;//(两端对齐的)文本对齐方式:(左,中,右,两端对齐,自然) paragraphStyle.lineBreakMode = NSLineBreakByTruncatingTail;//结尾部分的内容以……方式省略 ( "...wxyz" ,"abcd..." ,"ab...yz") paragraphStyle.headIndent = 20;//整体缩进(首行除外) paragraphStyle.tailIndent = 20;// paragraphStyle.minimumLineHeight = 10;//最低行高 paragraphStyle.maximumLineHeight = 20;//最大行高 paragraphStyle.paragraphSpacing = 15;//段与段之间的间距 paragraphStyle.paragraphSpacingBefore = 22.0f;//段首行空白空间/* Distance between the bottom of the previous paragraph (or the end of its paragraphSpacing, if any) and the top of this paragraph. */ paragraphStyle.baseWritingDirection = NSWritingDirectionLeftToRight;//从左到右的书写方向(一共??三种) paragraphStyle.lineHeightMultiple = 15;/* Natural line height is multiplied by this factor (if positive) before being constrained by minimum and maximum line height. */ paragraphStyle.hyphenationFactor = 1;//连字属性 在iOS,唯一支持的值分别为0和1 /* NSFontAttributeName 字体大小 NSParagraphStyleAttributeName 段落的风格(设置首行,行间距,对齐方式什么的) NSKernAttributeName 字间距 */ NSDictionary *attributes = @{ NSFontAttributeName:[UIFont systemFontOfSize:15], NSParagraphStyleAttributeName:paragraphStyle, NSKernAttributeName:@(10), }; textView.attributedText = [[NSAttributedString alloc] initWithString:textView.text attributes:attributes];
1.NSKernAttributeName: @10 调整字句 kerning 字句调整
2.NSFontAttributeName : [UIFont systemFontOfSize:_fontSize] 设置字体
3.NSForegroundColorAttributeName :[UIColor redColor] 设置文字颜色
4.NSParagraphStyleAttributeName : paragraph 设置段落样式
5.NSMutableParagraphStyle *paragraph = [[NSMutableParagraphStyle alloc] init];
paragraph.alignment = NSTextAlignmentCenter;
6.NSBackgroundColorAttributeName: [UIColor blackColor] 设置背景颜色
7.NSStrokeColorAttributeName设置文字描边颜色,需要和NSStrokeWidthAttributeName设置描边宽度,这样就能使文字空心.
NSStrokeWidthAttributeName这个属性所对应的值是一个 NSNumber 对象(小数)。该值改变描边宽度(相对于字体size 的百分比)。默认为 0,即不改变。正数只改变描边宽度。负数同时改变文字的描边和填充宽度。例如,对于常见的空心字,这个值通常为3.0。
同时设置了空心的两个属性,并且NSStrokeWidthAttributeName属性设置为整数,文字前景色就无效果了
效果:
效果:
8. NSStrikethroughStyleAttributeName 添加删除线,strikethrough删除线
效果:
9. NSUnderlineStyleAttributeName 添加下划线
效果:
10. NSShadowAttributeName 设置阴影,单独设置不好使,必须和其他属性搭配才好使。
和这三个任一个都好使,NSVerticalGlyphFormAttributeName,NSObliquenessAttributeName,NSExpansionAttributeName
11.NSVerticalGlyphFormAttributeName
该属性所对应的值是一个 NSNumber 对象(整数)。0 表示横排文本。1 表示竖排文本。在 iOS 中,总是使用横排文本,0 以外的值都未定义。
效果:
12. NSObliquenessAttributeName设置字体倾斜。Skew 斜
效果:
13. NSExpansionAttributeName 设置文本扁平化
效果:
