检测 NSString 中的撇号？
我正在使用 Gamekit 通过蓝牙在两个设备之间发送数据。我想获取发送它的设备的名称，但如果名称是“Bob's iPhone”，我想切断“'s iPhone”。我首先检查是否以“iPhone”或“iPod Touch”结尾。
if ([name hasSuffix:@" iPhone"])
{
name = [name substringToIndex:[name length]-7];
}
else if ([name hasSuffix:@" iPod Touch"])
{
name = [name substringToIndex:[name length]-11];
}
但是当我对“'s”做同样的事情时，它永远不会返回 true。此外，撇号看起来与默认撇号略有不同。
if ([name hasSuffix:@"'s"])
{
name = [name substringToIndex:[name length]-2];
}
有什么技巧可以检测撇号吗？我有办法做到这一点吗？
编辑： 左边的撇号是 name 包含的内容，但没有用 hasSuffix:@"'s" 注册。右边的撇号是我添加的撇号。
I'm using Gamekit to send data via bluetooth between two devices. I want to get the name of the device that sent it, but if the name is "Bob's iPhone" I want to cut off the "'s iPhone". I first check for ending in "iPhone" or "iPod Touch".
if ([name hasSuffix:@" iPhone"])
{
name = [name substringToIndex:[name length]-7];
}
else if ([name hasSuffix:@" iPod Touch"])
{
name = [name substringToIndex:[name length]-11];
}
But when I do the same for "'s" it never returns true. Also the apostrophe looks slightly different then the default apostrophe.
if ([name hasSuffix:@"'s"])
{
name = [name substringToIndex:[name length]-2];
}
Is there some trick to detecting apostrophes? Is there a way I can do this?
EDIT:
The apostrophe on the left is what name contains, but is not registering with hasSuffix:@"'s". The apostrophe on the right is the apostrophe I added.

可能是编码字符串的情况。您应该确保这种情况下的字符串
是
's或's或's或其他字符。您可能有其他一些性格给您带来问题。
这些是我的猜测。希望这可以帮助您找出问题所在。
It might be the case of encoded string. You should make sure the string about this cases
is it
'sor is it´sor is it‘sor some other character.You may have some other character that is causing you problems.
These are my guess. Hoping this helps you to find out your problem.
您想要
rangeOfString:NSString中的方法。You want the
rangeOfString:method inNSString.
