NSTextAlignmentJustified在iOS7中不起作用 [英] NSTextAlignmentJustified not working in iOS7

问题描述

我有一个使用 NSTextAlignmentJustified 的应用程序，用于 NSAttributedString 。在 iOS 6 中，一切都运行良好。但是在 iOS 7 （模拟器或设备没有任何区别）中运行的相同应用程序根本没有显示任何Justify。此外，从 iOS 6 到 7 ，线条间距似乎也发生了巨大变化。

I have an app which uses NSTextAlignmentJustified for an NSAttributedString. In iOS 6 everything is working great. But the same App running in iOS 7 (simulator or device makes no difference) is showing no Justify at all. Also the linespacing seems to have changed dramatically from iOS 6 to 7.

其他人遇到此问题？有没有办法在iOS 7中制作合理的Textblock（在iOS 6中也可以使用？）

Anyone else encountered this problem? Is there any way to make a justified Textblock in iOS 7 (which works in iOS 6 too?)

问候，
Markus

推荐答案

好的，我找到了一种在iOS 7中制作标签Justifiy的方法：
i只需将NSBaselineOffsetAttributeName设置为0。

Ok, i kind of found a way to make the label Justifiy in iOS 7: i simply set NSBaselineOffsetAttributeName to 0.

不知道为什么会有效，但它确实有效。

No idea why it works, but it works.

NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];
    paragraphStyle.lineBreakMode = NSLineBreakByWordWrapping;
    paragraphStyle.alignment = NSTextAlignmentJustified;

NSAttributedString *string = [[NSAttributedString alloc] initWithString:rawString 
          attributes:[NSDictionary dictionaryWithObjectsAndKeys:
          paragraphStyle, NSParagraphStyleAttributeName , 
          [NSNumber numberWithFloat:0],NSBaselineOffsetAttributeName, 
          nil]];
