1、富文本
2、渐变色lab

1、富文本这块建议把相关的值用model进行管理进行传输，我有代码https://github.com/295060456/JobsIM见
#import "NSObject+RichText.h"，
我没有pod
这么使用
{// 情况 1
NSMutableArray *tempDataMutArr = NSMutableArray.array;
RichLabelDataStringsModel *title_1_Model = RichLabelDataStringsModel.new;
RichLabelDataStringsModel *title_2_Model = RichLabelDataStringsModel.new;

        {
            title_1_Model.dataString = @"邀请好友,";
            
            RichLabelFontModel *richLabelFontModel = RichLabelFontModel.new;
            richLabelFontModel.font = [UIFont systemFontOfSize:18 weight:UIFontWeightBold];
            richLabelFontModel.range = NSMakeRange(0, title_1_Model.dataString.length);
            
            RichLabelTextCorModel *richLabelTextCorModel = RichLabelTextCorModel.new;
            richLabelTextCorModel.cor = RGBCOLOR(46, 51, 77);
            richLabelTextCorModel.range = NSMakeRange(0, title_1_Model.dataString.length);
            
            title_1_Model.richLabelFontModel = richLabelFontModel;
            title_1_Model.richLabelTextCorModel = richLabelTextCorModel;
        }
        
        {
            title_2_Model.dataString = @"无限赚抖币";
            
            RichLabelFontModel *richLabelFontModel = RichLabelFontModel.new;
            richLabelFontModel.font = [UIFont systemFontOfSize:18 weight:UIFontWeightBold];
            richLabelFontModel.range = NSMakeRange(title_1_Model.dataString.length, title_2_Model.dataString.length);
            
            RichLabelTextCorModel *richLabelTextCorModel = RichLabelTextCorModel.new;
            richLabelTextCorModel.cor = RGBCOLOR(231, 74, 99);
            richLabelTextCorModel.range = NSMakeRange(title_1_Model.dataString.length, title_2_Model.dataString.length);
            
            
            title_2_Model.richLabelFontModel = richLabelFontModel;
            title_2_Model.richLabelTextCorModel = richLabelTextCorModel;
        }
        
        [tempDataMutArr addObject:title_1_Model];
        [tempDataMutArr addObject:title_2_Model];
        
        _titleLab.attributedText = [NSObject makeRichTextWithDataConfigMutArr:tempDataMutArr];
    }

2、渐变色这块看下👇

以下是代码：

UILabel *label = [_tableView.ly_emptyView valueForKey:@"titleLabel"];

UIGraphicsBeginImageContextWithOptions(label.bounds.size, NO, [UIScreen mainScreen].scale);
CGContextRef context = UIGraphicsGetCurrentContext();
//绘制渐变层
CGColorSpaceRef colorSpaceRef = CGColorSpaceCreateDeviceRGB();
CGGradientRef gradientRef = CGGradientCreateWithColors(colorSpaceRef,
                                                       (__bridge CFArrayRef)@[(id)[UIColor redColor].CGColor,(id)[UIColor greenColor].CGColor],
                                                       NULL);
CGPoint startPoint = CGPointZero;
CGPoint endPoint = CGPointMake(CGRectGetMaxX(label.bounds), CGRectGetMaxY(label.bounds));
CGContextDrawLinearGradient(context, gradientRef, startPoint, endPoint,  kCGGradientDrawsBeforeStartLocation | kCGGradientDrawsAfterEndLocation);
//取到渐变图片
UIImage *gradientImage = UIGraphicsGetImageFromCurrentImageContext();
//释放资源
CGColorSpaceRelease(colorSpaceRef);
CGGradientRelease(gradientRef);
UIGraphicsEndImageContext();

label.textColor = [UIColor colorWithPatternImage:gradientImage];

都是干货哈。

#import "UIColor+Gradient.h"

    [CorDataMutArr addObject:(id)[UIColor greenColor].CGColor];
}else{
    for (int t = 0; t < CorDataMutArr.count; t++) {
        [CorDataMutArr replaceObjectAtIndex:t
                                 withObject:(id)CorDataMutArr[t].CGColor];
    }
}

CGPoint EndPoint = endPoint;
if (CGPointEqualToPoint(endPoint, CGPointZero)) {
    EndPoint = CGPointMake(CGRectGetMaxX(targetLabel.bounds),
                           CGRectGetMaxY(targetLabel.bounds));
}

CGContextDrawLinearGradient(context,
                            gradientRef,

//释放资源
CGColorSpaceRelease(colorSpaceRef);
CGGradientRelease(gradientRef);

return [UIColor colorWithPatternImage:gradientImage];

这里我更正下，以下是最新解决方案：
.h
#if __has_include(<LYEmptyView/LYEmptyViewHeader.h>)
#import <LYEmptyView/LYEmptyViewHeader.h>
#else
#import "LYEmptyViewHeader.h"
#endif

NS_ASSUME_NONNULL_BEGIN

@interface EmptyView : LYEmptyView

• (instancetype)diyEmptyViewWithTitle:(NSString *_Nullable)title;

• (instancetype)diyEmptyActionViewWithTarget:(id)target
  action:(SEL)action;

@EnD

NS_ASSUME_NONNULL_END

/*
_tableView.ly_emptyView = [EmptyView diyEmptyViewWithTitle:@"您还未关注账号"];
*/

.m
#import "EmptyView.h"

@implementation EmptyView

• (instancetype)diyEmptyViewWithTitle:(NSString *_Nullable)title{
  if ([NSString isNullString:title]) {
  title = @"快来将我填满吧";
  }
  return [EmptyView emptyViewWithImageStr:@"暂无数据"
  titleStr:title
  detailStr:@""];
  }

• (instancetype)diyEmptyActionViewWithTarget:(id)target
  action:(SEL)action{
  return [EmptyView emptyActionViewWithImageStr:@"noNetwork"
  titleStr:@"无网络连接"
  detailStr:@"请检查你的网络连接是否正确!"
  btnTitleStr:@"重新加载"
  target:target
  action:action];
  }

-(void)drawRect:(CGRect)rect{
[super drawRect:rect];

self.autoShowEmptyView = NO; //如果想要DemoEmptyView的效果都不是自动显隐的，这里统一设置为NO，初始化时就不必再一一去写了
self.titleLabFont = [UIFont systemFontOfSize:18 weight:UIFontWeightRegular];

UILabel *label = [self valueForKey:@"titleLabel"];
UIColor *cor = [UIColor gradientCorDataMutArr:[NSMutableArray arrayWithArray:@[RGBCOLOR(247, 131, 97),RGBCOLOR(245, 75, 100)]]
                                   startPoint:CGPointZero
                                     endPoint:CGPointZero
                                       opaque:NO
                              withTargetLabel:label];
self.titleLabTextColor = cor;

}

• (void)prepare{
  [super prepare];
  }

@EnD

因为：
// 上下文为 nil 或者 targetLabel没有被约束撑开都会失败
+(UIColor *)gradientCorDataMutArr:(NSMutableArray <UIColor >_Nullable)CorDataMutArr
startPoint:(CGPoint)startPoint
endPoint:(CGPoint)endPoint
opaque:(BOOL)opaque
withTargetLabel:(UILabel *_Nonnull)targetLabel；
