我现在使用
Xcode4.5和iOS6,iOS6已经改变了UILable的textAlignment,
label.textAlignment = NSTextAlignmentJustified;
该代码将在使用ios6 SDK的iPhone 6.0 Simulator上崩溃.但不会在iPhone 5.0模拟器与iOS6 SDK崩溃.
iOS6支持NSTextAlignmentJustified,但为什么会崩溃？
解决方法
编辑1：
使用NSAttributedString我们可以证明文本.
NSMutableParagraphStyle *paragraphStyles = [[NSMutableParagraphStyle alloc] init];
paragraphStyles.alignment = NSTextAlignmentJustified;
paragraphStyles.firstLineHeadIndent = 0.05; // Very IMP
NSString *stringTojustify = @"We are what our thoughts have made us; so take care about what you think. Words are secondary. Thoughts live; they travel far.";
NSDictionary *attributes = @{NSParagraphStyleAttributeName: paragraphStyles};
NSAttributedString *attributedString = [[NSAttributedString alloc] initWithString:stringTojustify attributes:attributes];
self.lblQuote.attributedText = attributedString;
self.lblQuote.numberOfLines = 0;
[self.lblQuote sizeToFit];
UITextAlignmentJustify的弃用,在iOS 6下不再可用.
在这个SO link也提供了所有可能的解决方案
看看this page和iOS6 prerelease Documentation.
