Easiest way to concatenate NSString and int
提问by DivideByHero
Is there a general purpose function in Objective-C that I can plug into my project to simplify concatenating NSStrings and ints?
Objective-C 中是否有通用函数可以插入到我的项目中以简化NSStrings 和ints 的连接？
回答by Genericrich
[NSString stringWithFormat:@"THIS IS A STRING WITH AN INT: %d", myInt];
That's typically how I do it.
这就是我通常的做法。

Both answers are correct. If you want to concatenate multiple strings and integers use NSMutableString's appendFormat.
两个答案都是正确的。如果要连接多个字符串和整数，请使用 NSMutableString 的 appendFormat。
NSMutableString* aString = [NSMutableString stringWithFormat:@"String with one int %d", myInt]; // does not need to be released. Needs to be retained if you need to keep use it after the current function.
[aString appendFormat:@"... now has another int: %d", myInt];

string1,x , these are declared as a string object and integer variable respectively. and if you want to combine both the values and to append int values to a string object and to assign the result to a new string then do as follows.
string1,x ，它们分别被声明为字符串对象和整数变量。如果您想组合这两个值并将 int 值附加到字符串对象并将结果分配给新字符串，请执行以下操作。
NSString *string1=@"Hello";
int x=10;
NSString *string2=[string1 stringByAppendingFormat:@"%d ",x];
NSLog(@"string2 is %@",string2);
//NSLog(@"string2 is %@",string2); is used to check the string2 value at console ;

NSString *s =
[
[NSString alloc]
initWithFormat:@"Concatenate an int %d with a string %@",
12, @"My Concatenated String"
];
I know you're probably looking for a shorter answer, but this is what I would use.
我知道您可能正在寻找更简短的答案，但这就是我会使用的。

It seems the real answer is no - there is no easy and short way to concatenate NSStrings with Objective C - nothing similar to using the '+' operator in C# and Java.
似乎真正的答案是否定的 - 没有简单快捷的方法将 NSStrings 与 Objective C 连接起来 - 没有什么类似于在 C# 和 Java 中使用“+”运算符。
