我如何知道 NSTextField 正在使用的行片段填充？
最佳答案
您可以将-lineFragmentPadding用于NSTextField的textContainer。像这样:
float lineFragmentPadding = [textContainer lineFragmentPadding];
例如:
NSSize textFieldSize = [textFieldOutlet frame].size;
NSTextStorage *textStorage = [[[NSTextStorage alloc] initWithAttributedString:[textFieldOutlet attributedStringValue]] autorelease];
NSTextContainer *textContainer = [[[NSTextContainer alloc] initWithContainerSize:NSMakeSize(textFieldSize.width, textFieldSize.height)] autorelease];
NSLayoutManager *layoutManager = [[[NSLayoutManager alloc] init] autorelease];
[layoutManager addTextContainer:textContainer];
[textStorage addLayoutManager:layoutManager];
[layoutManager glyphRangeForTextContainer:textContainer];
float lineFragmentPadding = [textContainer lineFragmentPadding];
NSLog(@"Padding: %f", lineFragmentPadding);
