在UILabel中展示表情符号？ [英] Showing emoji in a UILabel?

问题描述

不确定我在这里缺少什么，搜索没有帮助我。我想在UILabel中显示表情符号字符，而这不是这样：

Not sure what I'm missing here, and searching hasn't helped me. I want to display emoji characters in a UILabel, and this isn't doing it:

UILabel *label = [[UILabel alloc] init];
label.font = [UIFont fontWithName:@"AppleColorEmoji" size:16.0];
label.text = [NSString stringWithFormat:@"%C", 0x1F431];
// ... etc.

与其他非字母unicode字符一起使用，例如国际象棋棋子，但不是我试过的任何表情符号。

Works fine with other non-letter unicode characters, e.g. chess pieces, but not with any emoji characters that I have tried.

推荐答案

你可能没有使用正确的表情编码字符。例如，在你的例子中，我认为你正在寻找这样的东西：

You are probably not using the correct encoding for your emoji characters. For instance in your example I think you are looking for something like this:

label.text = [NSString stringWithFormat:@"%C", 0xe04f];

看看 this 表格可以获得你需要的编码。

Have a look at this table to get the encodings you need.
