objective-c - Cocoa NSTextField 行距

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距。我可以做些什么来减少行高或行距？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，

！）

Answer 1

作为参考，您想阅读段落样式的说明：Cocoa Paragraph Styles并注意其中的所有内容都在行之间、段落之间、段落之前等添加了额外的空间。您可以将 NSMutableParagraphStyle 中的值设置为零但不能更低。

要进一步缩小行间距，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];

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

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];

可以显示文本而不是输入文本。而且我只知道如何设置行距。
