Objective C在2个字符串concat之间插入变量

Question

我试图做以下(伪)

NSString *variable = 'Name'; 
NSString *newString = @"Hello, " + variable + @" blah blah";

它看起来并不像上面那么简单!有帮助吗？

谢谢

Answer 1

NSString *str = @"Hello, ";
str = [str stringByAppendingString:variable];
str = [str stringByAppendingString:@" blah blah"];

如果你喜欢它作为一行声明

 NSString *str = [[@"Hello, " stringByAppendingString:variable] stringByAppendingString:@" blah blah"];

迅速

var str = "Hello, " + varaible + "blah blah"

要么

var str = "Hello, \(variable) blah blah"
