iOS開發小技巧 - UILabel添加中劃線

iOS開發小技巧

遇到的問題: 給Label添加中劃線,而後並無效果

NSString *str = [NSString stringWithFormat:@"合計金額 ¥%.2f",model.amount];
NSDictionary *attrDic = @{
                        NSStrikethroughStyleAttributeName: @(1),
                        NSFontAttributeName : Font(FONT_SIZE_12)
                        };
NSMutableAttributedString *attrStr = [[NSMutableAttributedString alloc] initWithString:str attributes:attrDic];
self.priceLabel.attributedText = attrStr;

• 自我趕腳代碼是完美的,可是就是不出效果,捉急!

解決方案 : 增長一個富文本屬性 NSBaselineOffsetAttributeName : @(NSUnderlineStyleSingle)

NSString *str = [NSString stringWithFormat:@"合計金額 ¥%.2f",model.amount];
NSDictionary *attrDic = @{
                        NSStrikethroughStyleAttributeName: @(1),
                        NSFontAttributeName : Font(FONT_SIZE_12),
                        NSBaselineOffsetAttributeName : @(NSUnderlineStyleSingle)
                        };
NSMutableAttributedString *attrStr = [[NSMutableAttributedString alloc] initWithString:str attributes:attrDic];
self.priceLabel.attributedText = attrStr;
