Cocoa NSTextField行间距

Question

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个选项。

任何帮助都会非常感激！

周末愉快，

！）

Answer 1

作为参考，您想要阅读段落样式的这种描述：Cocoa Paragraph Styles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，感谢代码为“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];

Swift 版本的Jason Harrison优秀的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

Answer 3

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];

显示文本不是用于输入文本。我只知道如何设置行间距。
