在objectivec中组合字符串

Question

如何在objective-c中构思2个字符串,就像在VB.net中一样,你可以做"foo"和"bar"

Answer 1

NSString *newString = [@"foo" stringByAppendingString:@"bar"];

如果您要更改字符串,请考虑使用其可变变量 - NSMutableString它允许在不创建新实例的情况下追加字符串:

NSMutableString *mutString = [NSMutableString stringWithString:@"foo"];
[mutString appendString:@"bar"];
