将文本添加到NSTextView时如何使用格式代码

Question

I have a NSTextview called 'output' and it is set to non editable. I use

[self.output setString:[self.output.string stringByAppendingString:@"My string"]];

to add text to it. My question is, how to I use format codes in it? Example

[self.output setString:[self.output.string stringByAppendingString:@"%d",myInt]];

This throws error : Too many arguments to method call, expected 1, have 2. Is there any way to do this without an error?

Answer 1

您真正想要的是stringByAppendingFormat而不是stringByAppendingString。

[self.output setString:[self.output.string stringByAppendingFormat:@"%d",myInt]];
