是否可以在一个UIlabel中设置不同的字体?
看看NSAttributedString ...使用OHAttributedLabel画NSAttributedString因为的UILabel,UITextView的亘古不变的支持NSAttributedString ...
PS:如果你打算分发iOS6的或更新的应用程序,因为现在的UILabel支持NSAttributedString,您应该直接使用UILabel而不是OHAttributedLabel,因为它现在由操作系统本机支持。
它似乎很酷!,thx! – 2012-04-20 08:41:24
我还没有测试过,但我*认为*这是过时的iOS 6.0。最初的'UILabel'现在有一个'属性文字'属性 - 参见http://developer.apple.com/library/ios/documentation/uikit/reference/UILabel_Class/Reference/UILabel。html#// apple_ref/occ/instp/UILabel/attributedText – 2013-08-16 10:56:50
@MarkAmery我已更新我的其他答案,但忘记更新它。感谢您的通知。 http://stackoverflow.com/questions/4208282/advance-search-implementation-in-iphone/4208329#4208329 – KingofBliss 2013-08-16 12:10:24
我很抱歉,但是这是不可能用的UILabel实现,你有两个选择:
- 您可以创建一个UIWebView并把HTML格式的文本
- 你可以使自己的UILabel实现与functionallity例如,使用Core Text
而不是使用两个UILabels,您可以使用一个带有多种文本字体样式和颜色的标签。这里有一个例子:
UILabel *customLbl = [[UILabel alloc] initWithFrame:CGRectMake(50, 100, 200, 25)];
customLbl.backgroundColor = [UIColor yellowColor];
[self createTwoTextStyleInSingleUILabel:customLbl];// custom method calling
[self.view addSubview:customLbl];
自定义方法是这样的: 之前应用这种方法,在你的项目中添加QuartzCore框架(需要CALayers)和CoreText框架(所需属性串)。
#import <QuartzCore/QuartzCore.h>
#import <CoreText/CoreText.h>
- (void)createTwoTextStyleInSingleUILabel: (UILabel *) myLabel{
NSString *firstText = NSLocalizedString(@"First text:", nil);
NSString *secondText = [NSString stringWithFormat:@"%@ %@",firstText,@"Second text"];
CATextLayer *myLabelTextLayer;
/* Create the text layer on demand */
if (!myLabelTextLayer) {
myLabelTextLayer = [[CATextLayer alloc] init];
myLabelTextLayer.backgroundColor = [UIColor clearColor].CGColor;
myLabelTextLayer.wrapped = NO;
CALayer *layer = myLabel.layer; //assign layer to your UILabel
myLabelTextLayer.frame = CGRectMake((layer.bounds.size.width-180)/2 + 10, (layer.bounds.size.height-30)/2 + 10, 180, 30);
myLabelTextLayer.contentsScale = [[UIScreen mainScreen] scale];
myLabelTextLayer.alignmentMode = kCAAlignmentCenter;
[layer addSublayer:myLabelTextLayer];
}
/* Create the attributes (for the attributed string) */
// customizing first string
CGFloat fontSize = 16;
UIFont *boldFont = [UIFont boldSystemFontOfSize:fontSize];
CTFontRef ctBoldFont = CTFontCreateWithName((__bridge CFStringRef)boldFont.fontName, boldFont.pointSize, NULL);
CGColorRef cgColor = [UIColor redColor].CGColor;
NSDictionary *attributes = [NSDictionary dictionaryWithObjectsAndKeys:
(__bridge id)ctBoldFont, (id)kCTFontAttributeName,
cgColor, (id)kCTForegroundColorAttributeName, nil];
CFRelease(ctBoldFont);
// customizing second string
UIFont *font = [UIFont systemFontOfSize:16];
CTFontRef ctFont = CTFontCreateWithName((__bridge CFStringRef)font.fontName, font.pointSize, NULL);
CGColorRef cgSubColor = [UIColor blackColor].CGColor;
NSDictionary *subAttributes = [NSDictionary dictionaryWithObjectsAndKeys:(__bridge id)ctFont, (id)kCTFontAttributeName,cgSubColor, (id)kCTForegroundColorAttributeName, nil];
CFRelease(ctFont);
/* Create the attributed string (text + attributes) */
NSMutableAttributedString *attrStr = [[NSMutableAttributedString alloc] initWithString:secondText attributes:attributes];
float lengthOfSecondString = 12.0; // length of second string including blank space inbetween text, space in front , space after text.. Be careful, your app may crash here if length is beyond the second text length (lengthOfSecondString = text length + blank spaces)
[attrStr addAttributes:subAttributes range:NSMakeRange(firstText.length, lengthOfSecondString)];
// you can add another subattribute in the similar way as above , if you want change the third textstring style
/* Set the attributes string in the text layer :) */
myLabelTextLayer.string = attrStr;
myLabelTextLayer.opacity = 1.0; //to remove blurr effect
}
我会检查这个代码,真的thx :) – 2012-09-20 10:15:53
有设置不同的/多种字体使用NSMutableAttributedString上标签&其它性能的方法。 FOLL是我的代码:
UIFont *ArialFont = [UIFont fontWithName:@"arial" size:18.0];
NSDictionary *arialdict = [NSDictionary dictionaryWithObject: ArialFont forKey:NSFontAttributeName];
NSMutableAttributedString *AattrString = [[NSMutableAttributedString alloc] initWithString:title attributes: arialdict];
UIFont *VerdanaFont = [UIFont fontWithName:@"verdana" size:12.0];
NSDictionary *veradnadict = [NSDictionary dictionaryWithObject:VerdanaFont forKey:NSFontAttributeName];
NSMutableAttributedString *VattrString = [[NSMutableAttributedString alloc]initWithString: newsDate attributes:veradnadict];
[VattrString addAttribute:NSForegroundColorAttributeName value:[UIColor blackColor] range:(NSMakeRange(0, 15))];
[AattrString appendAttributedString:VattrString];
lblText.attributedText = AattrString;
注意lblText是的UILabel,插座,因为文件的所有者。
人们可以继续追加许多NSMutableAttributedString他想..
还要注意,我已经添加了宋体& Arial字体在我的项目&添加一个相同的plist中。
不工作.. [NSDictionary dictionaryWithObject:ArialFont forKey:NSFontAttributeName] ;在这一行中得到错误 – 2013-09-06 11:51:00
@RajeshPillai你有没有在第一行定义字体? UIFont * ArialFont = [UIFont fontWithName:@“arial”size:18.0]; – Akshay 2013-09-08 08:40:37
修改阿克沙伊的答案,并实现了它与斯威夫特:
// First part with font size 10
let firstPartInfo = [NSFontAttributeName: UIFont.systemFontOfSize(10.0)]
var attributedString = NSMutableAttributedString(string: "First Part", attributes: firstPartInfo)
// Second part with font size 20
let secondPartInfo = [NSFontAttributeName: UIFont.systemFontOfSize(20.0)]
attributedString.appendAttributedString(
NSAttributedString(string: "Second Part", attributes: secondPartInfo))
// Lastly set the attributed text
label.attributedText = attributedString
没有理由使用第三方解决方案或子类。
