Primitives can be converted to objects with @()expression. So the shortestway is to transform intto NSNumberand pick up string representation with stringValuemethod:
原语可以转换为带有@()表达式的对象。所以，最短的途径是转变int来NSNumber，拿起用字符串表示stringValue方法：
NSString *strValue = [@(myInt) stringValue];
or
或者
NSString *strValue = @(myInt).stringValue;

int i = 25;
NSString *myString = [NSString stringWithFormat:@"%d",i];
This is one of many ways.
这是许多方法之一。

If this string is for presentation to the end user, you should use NSNumberFormatter. This will add thousands separators, and will honor the localization settings for the user:
如果此字符串用于呈现给最终用户，则应使用NSNumberFormatter. 这将添加数千个分隔符，并将遵守用户的本地化设置：
NSInteger n = 10000;
NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init];
formatter.numberStyle = NSNumberFormatterDecimalStyle;
NSString *string = [formatter stringFromNumber:@(n)];
In the US, for example, that would create a string 10,000, but in Germany, that would be 10.000.
例如，在美国，这将创建一个 string 10,000，但在德国，这将是10.000.
