是否有可能有一个 NSString
的第一个单词具有一种字体大小/颜色,而下一个单词具有另一种字体大小和颜色?
我在想也许是 NSAttributedString
- 但不确定那是不是要走的路?
我尝试将两个 NSString
放入 NSAttributedString
- 但这没有用。
寻找具有以下内容的 UILabel:
工作示例
到目前为止,我想出了这个:
/* Set the Font Sizes */
UIFont *objectNameFont = [UIFont systemFontOfSize:14.f];
UIFont *itemsFont = [UIFont systemFontOfSize:12.f];
/* Create the attribute dictionaries */
NSDictionary *objectNameDict = [NSDictionary dictionaryWithObject:objectNameFont forKey:NSFontAttributeName];
NSDictionary *objectItemDict = [NSDictionary dictionaryWithObject:itemsFont forKey:NSFontAttributeName];
/* Create the string */
NSString *labelFullName = [NSString stringWithFormat:@"%@ (%@)", object.name, object.items];
/* Seperate the two strings */
NSArray *components = [labelFullName componentsSeparatedByString:@" ("];
NSRange objectNameRange = [labelFullName rangeOfString:[components objectAtIndex:0]];
NSRange objectItemRange = [labelFullName rangeOfString:[components objectAtIndex:1]];
/* Create the Attributed string */
NSMutableAttributedString *attrString = [[NSMutableAttributedString alloc] initWithString:labelFullName];
/* Start the editiong */
[attrString beginEditing];
[attrString addAttribute: NSForegroundColorAttributeName
value:[UIColor colorWithRed:0.667 green:0.667 blue:0.667 alpha:1] /*#aaaaaa*/
range:objectItemRange];
[attrString addAttribute: NSForegroundColorAttributeName
value:[UIColor colorWithRed:0.271 green:0.271 blue:0.271 alpha:1] /*#454545*/
range:objectNameRange];
[attrString addAttributes:objectNameDict range:objectNameRange];
[attrString addAttributes:objectItemDict range:objectItemRange];
[attrString endEditing];
cell.title.attributedText = attrString;
return cell;
这似乎可以满足我的需要。但是,两个字符串“(”的分隔符是黑色的,我需要它与此处设置的
object.items
颜色相同:[attrString addAttribute: NSForegroundColorAttributeName value:[UIColor colorWithRed:0.667 green:0.667 blue:0.667 alpha:1] /*#aaaaaa*/ range:objectItemRange];
找到解决方案
我找到了一个适合我的解决方案:
我拉出字符串并将它们放入
NSArray
并使用 objectAtIndex 获取它们的 NSRange
值来设置文本有任何想法吗?
谢谢大家。
最佳答案
是的,您可以拥有。
您还获得了该 NSAttributedString
的正确 Class 。
在以下代码中,使用了两种字体大小 12 和 15:
UIFont *font=[UIFont fontWithName:@"Arial" size:12.f];
NSDictionary *attrsDict=[NSDictionary dictionaryWithObject:font
forKey:NSFontAttributeName];
NSAttributedString *attribString=[[NSAttributedString alloc] initWithString:[words[0] substringFromIndex:1] attributes:attrsDict];
UIFont *fontFirst=[UIFont fontWithName:@"Arial" size:15.f];
NSDictionary *attrsDictFirst=[NSDictionary dictionaryWithObject:font forKey:NSFontAttributeName];
NSAttributedString *firstString=[[NSAttributedString alloc] initWithString:[attribString subStringToIndex:1] attributes:attrsDictFirst];
[attribString replaceCharactersInRange:NSMakeRange(0, 1) withString:firstString];
