我想在我的文本视图中格式化测试,一些文本是粗体的,一些东西是斜体的。uitextview可以吗?现在,我正在使用带有HTML字符串的webview。例如:
<html><head><style type=\"text/css\">h3 {color:white;} p {color:pink;} p {text-align: center} p {font-family:helvetica;font-size:20px;}</style></head><body>\
<h3></h3>\
<p><b>some text </b></p>\
<p>Short some text</p>\
<p>Child Infusion 7.5 to 15 mg/kg/hr<br>ie 7.5 to 15 times weight per hour</p>\
<p>Adult Infusion 3 to 12 mg/kg/hr<br>ie 3 to 12 mg times weight per hour</p>\
</body></html>发布于 2013-02-07 18:01:54
你可以使用NSAttributedString,设置文本字体,前景和背景颜色,StrikeThrough和阴影等。
属性字符串在字符及其属性之间建立关联。与NSString对象类似,也有两种变体: NSAttributedString和NSMutableAttributedString。尽管以前的iOS版本支持属性字符串,但直到iOS 6才定义了按钮、标签、文本字段和文本视图等控件的属性来管理属性。属性应用于一定范围的字符,因此,例如,可以仅为字符串的一部分设置删除线属性。同样重要的是要注意,属性字符串对象的默认字体是Helvetica 12点。如果您为范围而不是完整字符串设置字体属性,请记住这一点。可以使用属性字符串设置以下属性: NSString *const NSFontAttributeName;NSString *const NSParagraphStyleAttributeName;NSString *const NSForegroundColorAttributeName;NSString *const NSBackgroundColorAttributeName;NSString *const NSLigatureAttributeName;NSString *const NSKernAttributeName;NSString *const NSStrikethroughStyleAttributeName;NSString *const NSUnderlineStyleAttributeName;NSString *const NSStrokeColorAttributeName;NSString *const;*const;*const;
下面是一些例子
//-----------------------------
// Create attributed string
//-----------------------------
NSString *str = @"example for underline \nexample for font \nexample for bold \nexample for italics";
NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:str];
// Add attribute NSUnderlineStyleAttributeName
//[attributedString addAttribute:NSUnderlineStyleAttributeName value:[NSNumber numberWithInt:NSUnderlineStyleSingle] range:NSMakeRange(12, 9)];
[attributedString addAttribute:NSUnderlineStyleAttributeName value:[NSNumber numberWithInt:NSUnderlineStyleSingle] range:NSMakeRange(12, 9)];
// Set background color for entire range
[attributedString addAttribute:NSBackgroundColorAttributeName
value:[UIColor yellowColor]
range:NSMakeRange(0, [attributedString length])];
// Create NSMutableParagraphStyle object
NSMutableParagraphStyle *paragraph = [[NSMutableParagraphStyle alloc] init];
paragraph.alignment = NSTextAlignmentCenter;
// Add attribute NSParagraphStyleAttributeName
[attributedString addAttribute:NSParagraphStyleAttributeName value:paragraph range:NSMakeRange(0, [attributedString length])];
// Set font, notice the range is for the whole string
UIFont *font = [UIFont fontWithName:@"Helvetica" size:18];
[attributedString addAttribute:NSFontAttributeName value:font range:NSMakeRange(35, 4)];
// Set font, notice the range is for the whole string
UIFont *fontBold = [UIFont fontWithName:@"Helvetica-Bold" size:18];
[attributedString addAttribute:NSFontAttributeName value:fontBold range:NSMakeRange(53, 4)];
// Set font, notice the range is for the whole string
UIFont *fontItalics = [UIFont fontWithName:@"Helvetica-Oblique" size:18];
[attributedString addAttribute:NSFontAttributeName value:fontItalics range:NSMakeRange(71, 7)];
// Set label text to attributed string
[self.mytextView setAttributedText:attributedString];`
