删除来自保存在 NSString 中的 html 字符串

NSString* test = @"<b> Terms and Conditions</b><br />
- No  smoking(by law) <br />
 &amp;nbsp; No chewing pan(by law)<br />"
[test stringByReplacingOccurrencesOfString:@"&amp;nbsp;" withString:@"s"];

我尝试删除该 " " 但失败了？有什么想法吗？

谢谢

原文

NSString* test = @"<b> Terms and Conditions</b><br />
- No  smoking(by law) <br />
 &nbsp; No chewing pan(by law)<br />"
[test stringByReplacingOccurrencesOfString:@"&nbsp;" withString:@"s"];

I tried to remove that " " but it fails to do so? Any ideas??

Thanks

test 是一个不可变的字符串，在进行替换时您会忽略结果。试试这个：

test = [test stringByReplacingOccurrencesOfString:@"&nbsp;" withString:@"s"];

test is an immutable string and you are ignoring the result when you do the replacement. Try this:

test = [test stringByReplacingOccurrencesOfString:@"&nbsp;" withString:@"s"];

此方法不会更改您向其发送消息的字符串，而是返回一个新字符串。

NSString *newStr = [test stringByReplacingOccurrencesOfString:@"&nbsp;"
                                                   withString:@"s"];

This method doesn't change the string to which you send the message, but rather returns a new string.

NSString *newStr = [test stringByReplacingOccurrencesOfString:@"&nbsp;"
                                                   withString:@"s"];

我尝试使用以下单元测试来操作该字符串：

- (void) testStringManipulation {
    NSString* test = @"<b> Terms and Conditions</b><br />   - No  smoking(by law) <br /> &nbsp; No chewing pan(by law)<br />";
    NSString* expected = @"<b> Terms and Conditions</b><br />   - No  smoking(by law) <br /> s No chewing pan(by law)<br />";
    NSString *result = [test stringByReplacingOccurrencesOfString:@"&nbsp;" withString:@"s"];
    STAssertTrue([expected isEqualToString:result], @"Should be true");
}

这会在我的 IDE 中通过。
我正在使用 OCUnit。

您是否将[test stringByReplacingOccurrencesOfString... 放入新变量中？
此方法不会改变对象，但返回一个新的字符串实例。

I tried to manipulate the string with the following unit test:

- (void) testStringManipulation {
    NSString* test = @"<b> Terms and Conditions</b><br />   - No  smoking(by law) <br /> &nbsp; No chewing pan(by law)<br />";
    NSString* expected = @"<b> Terms and Conditions</b><br />   - No  smoking(by law) <br /> s No chewing pan(by law)<br />";
    NSString *result = [test stringByReplacingOccurrencesOfString:@"&nbsp;" withString:@"s"];
    STAssertTrue([expected isEqualToString:result], @"Should be true");
}

This passes in my IDE.
I'm using OCUnit.

Did you put the [test stringByReplacingOccurrencesOfString... in a new variable?
This method does not mutate the object, but returns a new string instance.
