可可 NSTextField 行距

发布于 2024-12-19 03:09:11 字数 152 浏览 4 评论 0原文

我正在努力解决一个非常简单的问题，我有几个 NSTextField （我现在无法使用 NSTextView），并且我需要更改显示文本的行距。我可以做什么来减少行高或行间距？缩小字体大小不是一个选项。

任何帮助将非常感激！

周末愉快，

！）

作为参考，您需要阅读段落样式的描述： Cocoa 段落样式并注意其中的所有内容之间都添加了额外的空格行、段落之间、段落之前等。您可以将 NSMutableParagraphStyle 中的值设置为零但不能更低。

要进一步缩小行之间的间距，请使用 setMaximumLineHeight，感谢代码中的“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];

For reference you want to read this description of paragraph styles: Cocoa Paragraph Styles and note that everything in there is additional space added between lines, between paragraphs, before paragraphs, etc. You can set the values in your NSMutableParagraphStyle to zero but no lower.

To further shrink the spacing between lines, use setMaximumLineHeight, thanks to "6 1" for the code (I've add the 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];

Jason Harrison 出色的 Obj-c 答案的 Swift 版本：

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

Swift version of Jason Harrison's excellent Obj-c answer:

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];

显示文本而不是输入文本是可以的。而且我只知道如何设置行距。

you can use NSAttributedString to show the text.

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];

It's ok to display text not for inputing text. And I only know how to set line spacing.
