iOS 富文本编辑工厂, 省去繁琐的编辑代码

项目介绍：

对比:

之前:

    NSShadow *shadow = [NSShadow new];
    shadow.shadowColor = [UIColor orangeColor];
    shadow.shadowOffset = CGSizeMake(0.2, 0.2);
    NSAttributedString *testAttr = [[NSAttributedString alloc] initWithString:@"test" attributes:@{NSFontAttributeName:[UIFont systemFontOfSize:12], NSForegroundColorAttributeName:[UIColor redColor], NSShadowAttributeName:shadow}];

现在:

// 可修改整体, 也可修改指定范围.
testAttr = [SJAttributesFactory alterStr:@"test" block:^(SJAttributesFactory *worker) {
        // 修改整体
        worker.font([UIFont systemFontOfSize:12])
        .expansion(0.5)
        .fontColor([UIColor redColor])
        .shadow(shadow)
        .backgroundColor([UIColor greenColor])
        .lineSpacing(5)
        .alignment(NSTextAlignmentLeft)
        .underline([UIColor redColor]); // 等等
        
        // 修改指定范围
        worker.nextFont([UIFont systemFontOfSize:20])
        .nextFontColor([UIColor yellowColor])
        .nextOffset(0.3)
        .nextLetterpress()
        .range(NSMakeRange(1, 2));  // 指定范围
    }];
