将unichar添加到NSMutableString

Question

如何将unichar字符附加到NSMutableString？

unichar c = 'T'; 
NSMutableString *s = [NSMutableString stringWithString:@"MyString"]; 

// want s to become "MyStringT"

[s appendString:[NSString stringWithCharacters:&c length:1]]; 

看起来太长/复杂...

Answer 1

使用[NSString的appendFormat：]，所以上面：

[s appendFormat:@"%C", c]; 

享受！
