Cocoa NSTextField行間距

Question

我正在努力解決一個非常簡單的問題，我有幾個NSTextField（我現在不能使用NSTextView），我需要更改顯示文本的行間距。 我該怎么做才能減少行高或行間距？ 縮小字體大小不是一種選擇。

任何幫助將非常感激！

周末愉快，

！）

Answer 1

作為參考，您想要閱讀段落樣式的這種描述： Cocoa Paragraph樣式並注意，其中的所有內容都在行之間，段落之間，段落之間添加了額外的空間。您可以將NSMutableParagraphStyle中的值設置為零但不低。

要進一步縮小行之間的間距，請使用setMaximumLineHeight，這要歸功於代碼的“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];

斯威夫特版傑森哈里森出色的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來顯示文本。

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];

可以顯示不用於輸入文本的文本。 我只知道如何設置行間距。
