objective-c - 将 unichar 附加到 NSMutableString

Question

你如何附加一个unichar字符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/复杂...

Answer 1

使用 [NSString appendFormat:]，所以对于上面：

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

享受！
