[英]Cocoa NSTextField line spacing
我正在努力解决一个非常简单的问题,我有几个NSTextField(我现在不能使用NSTextView),我需要更改显示文本的行间距。 我该怎么做才能减少行高或行间距? 缩小字体大小不是一种选择。
任何帮助将非常感激!
周末愉快,

作为参考,您想要阅读段落样式的这种描述: Cocoa Paragraph样式并注意,其中的所有内容都在行之间,段落之间,段落之间添加了额外的空间。您可以将NSMutableParagraphStyle中的值设置为零但不低。
要进一步缩小行之间的间距,请使用setMaximumLineHeight,这要归功于代码的“6 1”(我添加了setMaximumLineHeight):
NSString *title = @"title here";
NSFont *bold14 = [NSFont boldSystemFontOfSize:14.0];
NSColor *textColor = [NSColor redColor];
NSMutableParagraphStyle *textParagraph = [[NSMutableParagraphStyle alloc] init];
[textParagraph setLineSpacing:10.0]; // this sets the space BETWEEN lines to 10points
[textParagraph setMaximumLineHeight:12.0]; this sets the MAXIMUM height of the lines to 12points
NSDictionary *attrDic = [NSDictionary dictionaryWithObjectsAndKeys:bold14, NSFontAttributeName, textColor, NSForegroundColorAttributeName, textParagraph, NSParagraphStyleAttributeName, nil];
NSAttributedString *attrString = [[NSAttributedString alloc] initWithString:title attributes:attrDic];
[self.titleField setAllowsEditingTextAttributes:YES];
[self.titleField setAttributedStringValue:attrString];
斯威夫特版杰森哈里森出色的Obj-c答案:
let title:String = "title here"
let bold14:NSFont = NSFont.boldSystemFontOfSize(14.0)
let textColor:NSColor = NSColor.redColor()
let textParagraph:NSMutableParagraphStyle = NSMutableParagraphStyle()
textParagraph.lineSpacing = 10.0 /*this sets the space BETWEEN lines to 10points*/
textParagraph.maximumLineHeight = 12.0/*this sets the MAXIMUM height of the lines to 12points*/
let attribs = [NSFontAttributeName:bold14,NSForegroundColorAttributeName:textColor,NSParagraphStyleAttributeName:textParagraph]
let attrString:NSAttributedString = NSAttributedString.init(string: title, attributes: attribs)
textField.attributedStringValue = attrString
您可以使用NSAttributedString来显示文本。
NSFont *bold14 = [NSFont boldSystemFontOfSize:14.0];
NSColor *textColor = [NSColor redColor];
NSMutableParagraphStyle *textParagraph = [[NSMutableParagraphStyle alloc] init];
[textParagraph setLineSpacing:10.0];
NSDictionary *attrDic = [NSDictionary dictionaryWithObjectsAndKeys:bold14, NSFontAttributeName, textColor, NSForegroundColorAttributeName, textParagraph, NSParagraphStyleAttributeName, nil];
NSAttributedString *attrString = [[NSAttributedString alloc] initWithString:title attributes:attrDic];
[self.titleField setAllowsEditingTextAttributes:YES];
[self.titleField setAttributedStringValue:attrString];
可以显示不用于输入文本的文本。 我只知道如何设置行间距。
