Answer 1

您可以尝试将文本中的撇号加倍（即''而不是' ）。

Answer 2

This may be of some help as well when you want to replace a single quote with two double quotes.

Method:

 - (NSString *)stringByReplacingOccurrencesOfString:(NSString *)target withString:(NSString *)replacement

Example:

[someString stringByReplacingOccurrencesOfString:@"'" withString:@"''"]

Answer 3

你应该将撇号加倍“加倍”

Answer 4

A string constant is formed by enclosing the string in single quotes ('). A single quote within the string can be encoded by putting two single quotes in a row - as in Pascal. C-style escapes using the backslash character are not supported because they are not standard SQL.
