具体如下处理
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
NSAttributedString *attrStr= [[NSAttributedString alloc] initWithData:[shipInfo dataUsingEncoding:NSUTF8StringEncoding] options:@{NSDocumentTypeDocumentAttribute:NSHTMLTextDocumentType,NSCharacterEncodingDocumentAttribute:@(NSUTF8StringEncoding)} documentAttributes:nil error:nil];
NSMutableAttributedString * mutableAttrStr = [[NSMutableAttributedString alloc] initWithAttributedString:attrStr];
[mutableAttrStr addAttribute:NSFontAttributeName value:[UIFont systemFontOfSize:11] range:NSMakeRange(0, attrStr.string.length)];
//处理两个文本不居中对齐的方法：（11--11）：大字体 --- 小字体
[attStr addAttribute:NSBaselineOffsetAttributeName value:@(0.36 * (11 - 11)) range:NSMakeRange(0, shipDiscount.length)];
dispatch_async(dispatch_get_main_queue(), ^{
//主线程赋值 并更新布局
freeView.contenLabel.attributedText = mutableAttrStr;
freeView.contenLabel.textAlignment = NSTextAlignmentCenter;
});
});
