将双引号添加到NSString [英] Adding double quotes to NSString

问题描述

我试图创建一个如下所示的字符串：

SomeString=AnotherString

以下是我必须插入双引号的代码：

  NSString * newOutput = [NSString stringWithFormat：@％@ \= \％@，output，[englishDic objectForKey：str]]; 
  

所有它输出的是：

<$ p $
RateThisAppDontAsk \= \不要再询问


<

 RateThisAppDontAsk \ \不要再询问
  

任何帮助都将非常感谢！

解决方案

$ b在一个小小的MacOS X命令行测试程序中工作。 $ b

  #import&l t; Foundation / Foundation.h> 
 
 int main（int argc，const char * argv []）
 {
 @autoreleasepool {
 NSString * newOutput = NSString stringWithFormat：@％@ \= \％@，@foo，@bar]; 
 NSLog（newOutput）; 
} 
 return 0; 
 
 
 
 $ b $输出是：
 
  $ b  pre>  test [54844：403] foo=bar 
  

如果您要在 foo 之前和 bar 之后加引号，请添加以下内容：



  NSString * newOutput = [NSString stringWithFormat：@\％@ \= \％@ \，@foo，@bar]; 
  

新的输出是：



  test [54873：403]foo=bar
  




I have reading everything and \" does NOT work.

I am trying to create a string that looks like this:

"SomeString" = "AnotherString"

Here is the code that I have to insert the double quotes:

NSString *newOutput = [NSString stringWithFormat:@"%@ \" = \" %@", output, [englishDic objectForKey:str]];

All that it outputs is:

"RateThisAppDontAsk \" = \" Don't ask again"

I thought maybe the "=" was causing problems but removing still gives me an output of this:

"RateThisAppDontAsk \"  \" Don't ask again"

Any help would be very much appreciated!

解决方案

Works for me in a little MacOS X command line test program. Here's all the code:

#import <Foundation/Foundation.h>

int main(int argc, const char * argv[])
{
    @autoreleasepool {
        NSString *newOutput = [NSString stringWithFormat:@"%@ \" = \" %@", @"foo", @"bar"];
        NSLog(newOutput);
    }
    return 0;
}

Output is:

test[54844:403] foo " = " bar

If you want quotes before foo and after bar, add those:

NSString *newOutput = [NSString stringWithFormat:@"\"%@\" = \"%@\"", @"foo", @"bar"];

New output is:

test[54873:403] "foo" = "bar"
