可可NSTextField行間距

Question

我掙扎着一個非常簡單的問題，我有幾個NSTextField（我現在不能使用NSTextView），我需要改變顯示文本的行間距。 我可以做些什麼來減少行高或行間距？縮小字號不是一個選項。

任何幫助將非常感謝！

有一個偉大的週末，

Answer 1

可以使用NSAttributedString顯示文本。

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]; 

可以顯示不是用於輸入文字的文字。而且我只知道如何設置行間距。

爲了便於參考，您需要閱讀對段落樣式的描述：Cocoa Paragraph Styles並注意在那裏的所有內容都在行之間，段落之間，段落之前添加了額外的空間。您可以將NSMutableParagraphStyle中的值設置爲零，但不設置降低。

進一步萎縮線，使用setMaximumLineHeight，感謝之間的間距，以「6 + 1」的代碼（我已經添加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];

斯威夫特版本賈森·哈里森的出色Obj-的c回答：

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
