Question

为什么这段代码在IOS7中不起作用的原因是什么？我试图设置颜色，但颜色不会改变，它会保持黑色：

NSDictionary *attributes = [NSDictionary dictionaryWithObject:[UIColor redColor] forKey:NSForegroundColorAttributeName];
NSAttributedString *subString = [[NSAttributedString alloc] initWithString:@"abc" attributes:attributes];

UITextView *textView = ....

textView.attributedText = subString;

使用这个我相信它有效，因为我已经测试了

    NSDictionary *attributes = [NSDictionary dictionaryWithObjectsAndKeys:[UIColor redColor], NSForegroundColorAttributeName, nil];
    NSAttributedString *subString = [[NSAttributedString alloc] initWithString:@"abc" attributes:attributes];

NSAttributedString在IOS7中不工作UITextVIew
