我想把一根绳子放在一根绳子里.基本上是伪代码:
"first part of string" + "(varying string)" + "third part of string"
我如何在objective-c中做到这一点？有没有办法在obj-c中轻松连接？谢谢

是的，是的
NSString *str = [NSString stringWithFormat: @"first part %@ second part", varyingString];
对于串联，可以使用stringByAppendingString
NSString *str = @"hello ";
str = [str stringByAppendingString:@"world"]; //str is now "hello world"
对于多个字符串
NSString *varyingString1 = @"hello";
NSString *varyingString2 = @"world";
NSString *str = [NSString stringWithFormat: @"%@ %@", varyingString1, varyingString2];
//str is now "hello world"
