I know there are some open open source controls like DYRating etc.. But iam not able to add it in tableview cell .
我知道有一些开源控件，如 DYRating 等。但我无法将它添加到 tableview 单元格中。

You can check the ASStar rating .
您可以查看 ASStar 评级。
Add the control directly to your view controller or you can add into your cell .
将控件直接添加到您的视图控制器，或者您可以添加到您的单元格中。
And here is github link.

I recommend HCSStarRatingView. It is native-looking and it also supports IB_DESIGNABLEand IBInspectable.
我推荐HCSStarRatingView。它具有原生外观，并且还支持IB_DESIGNABLE和IBInspectable。

Note: This is a "DISPLAY ONLY" one.
注意：这是一个“仅显示”的。
I took a different approach here, I created a label with attributed string using a font with stars, you can check my category here. I used "SS Pika" font,
我在这里采用了不同的方法，我使用带星号的字体创建了一个带有属性字符串的标签，您可以在此处查看我的类别。我使用了“SS Pika”字体，
#import "NSMutableAttributedString+Stars.h"
@implementation NSMutableAttributedString (Stars)
+ (NSAttributedString *)starWithRating:(CGFloat)rating
outOfTotal:(NSInteger)totalNumberOfStars
withFontSize:(CGFloat) fontSize{
UIFont *currentFont = [UIFont fontWithName:@"SS Pika" size:fontSize];
NSDictionary *activeStarFormat = @{
NSFontAttributeName : currentFont,
NSForegroundColorAttributeName : [UIColor redColor]
};
NSDictionary *inactiveStarFormat = @{
NSFontAttributeName : currentFont,
NSForegroundColorAttributeName : [UIColor lightGrayColor]
};
NSMutableAttributedString *starString = [NSMutableAttributedString new];
for (int i=0; i < totalNumberOfStars; ++i) {
//Full star
if (rating >= i+1) {
[starString appendAttributedString:[[NSAttributedString alloc]
initWithString:@"\u22C6 " attributes:activeStarFormat]];
}
//Half star
else if (rating > i) {
[starString appendAttributedString:[[NSAttributedString alloc]
initWithString:@"\uE1A1 " attributes:activeStarFormat]];
}
// Grey star
else {
[starString appendAttributedString:[[NSAttributedString alloc]
initWithString:@"\u22C6 " attributes:inactiveStarFormat]];
}
}
return starString;
}
@end
USAGE:
用法：
self.ratingLabel.attributedText = [NSMutableAttributedString starWithRating:rating outOfTotal:5 withFontSize:9.0f];
Here is the SWIFT Version
这是 SWIFT 版本
extension NSMutableAttributedString{
func starWithRating(rating:Float, outOfTotal totalNumberOfStars:NSInteger, withFontSize size:CGFloat) ->NSAttributedString{
let currentFont = UIFont(name: "<USE UR FONT HERE>", size: size)!
let activeStarFormat = [ NSFontAttributeName:currentFont, NSForegroundColorAttributeName: UIColor.redColor()];
let inactiveStarFormat = [ NSFontAttributeName:currentFont, NSForegroundColorAttributeName: UIColor.lightGrayColor()];
let starString = NSMutableAttributedString()
for(var i = 0; i < totalNumberOfStars; ++i){
if(rating >= Float(i+1)){
// This is for selected star. Change the unicode value according to the font that you use
starString.appendAttributedString(NSAttributedString(string: "\u{22C6} ", attributes: activeStarFormat))
}
else if (rating > Float(i)){
// This is for selected star. Change the unicode value according to the font that you use
starString.appendAttributedString(NSAttributedString(string: "\u{E1A1} ", attributes: activeStarFormat))
}
else{
// This is for de-selected star. Change the unicode value according to the font that you use
starString.appendAttributedString(NSAttributedString(string: "\u{22C6} ", attributes: inactiveStarFormat))
}
}
return starString
}
}
USAGE:
用法：
starLabel.attributedText = NSMutableAttributedString().starWithRating(3.5, outOfTotal: 5, withFontSize: 8.0)
starLabelFull.attributedText = NSMutableAttributedString().starWithRating(5, outOfTotal: 5, withFontSize: 8.0)
starLabelZero.attributedText = NSMutableAttributedString().starWithRating(0, outOfTotal: 5, withFontSize: 8.0)

I just wrote this simple UIView subclass that draws stars rating from 0 to 5 including half stars. You can set the color with tintColor property and set the rating in interface editor. View width should be set to 5 * height.
我刚刚编写了这个简单的 UIView 子类，它绘制了从 0 到 5 的星级，包括半颗星。您可以使用 tintColor 属性设置颜色并在界面编辑器中设置评级。视图宽度应设置为 5 * 高度。

Use https://github.com/hugocampossousa/HCSStarRatingView. it easy to implement this. just write down these lines of code. Create IBOutlet HCSStarRatingView for in .h file an create one string for storing the rating value.
使用https://github.com/hugocampossousa/HCSStarRatingView。很容易实现这一点。只需写下这些代码行。在 .h 文件中为 IBOutlet HCSStarRatingView 创建一个用于存储评级值的字符串。

Yeah there are many libraries which you can use to make such controls like cosmos Cosmos library for rating control
是的，您可以使用许多库来制作此类控件，例如用于评级控制的 Cosmos Cosmos 库
if you want something like that looks like rating graph (like the one in image)then you can see this repo in github Rating graph view in iOS
如果你想要类似评级图的东西（就像图片中的那个），那么你可以在 iOS 的github评级图视图中看到这个 repo

If all you want is whole numbers of stars, you can use a simple String Array and use it to set the text property of a UILabel.
如果你想要的是整数个星星，你可以使用一个简单的字符串数组并用它来设置 UILabel 的文本属性。
##代码##Make sure you set the font of the UILabel to one which displays the black and white stars at the same size. Many but not all do.
确保将 UILabel 的字体设置为以相同大小显示黑白星星的字体。许多但不是全部。
