split() is a member function in the QString class that splits a string into substrings and stores the results in a list of strings.
The following are common uses of the split() function:
QString str = "Hello, World!";
QStringList stringList = str.split(", "); // 返回 ["Hello", "World!"]
In this example, we have a string str that reads "Hello, World!". By calling the split() function and passing an argument as the separator, you can split a string into multiple substrings and store the result in a QStringList object.
In the split() function, we pass a parameter as the delimiter, here we use ", " as the delimiter. Call split(", ") to split the string str using commas and spaces as delimiters to generate a QStringList containing two substrings, That is ["Hello", "World!"].
It should be noted that the split() function returns a list of strings containing split substrings. The original string is not modified.
