将unichar附加到NSMutableString

Question

你如何追加一个unichar角色NSMutableString？

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

// want s to become "MyStringT"

https://discussions.apple.com/thread/1679290建议:

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

看起来太长/太复杂......

Answer 1

使用[NSString appendFormat:],所以对于上面:

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