I'm having trouble converting a string into an integer. I googled it but all I can find is how to convert an int into a string. Does anyone know how to do it the other way around? Thanks.

In Python an strings can be converted into a integer using the built-in int() function. The int() function takes in any python data type and converts it into a integer.
Strings can be converted to numbers by using the int() and float() methods. If your string does not have decimal places, you'll most likely want to convert it to an integer by using the int() method.
One effective way to convert a string object into a numeral int is to use the stoi() function. This method is commonly used for newer versions of C++, with is being introduced with C++11. It takes as input a string value and returns as output the integer version of it.
The method generally used to convert String to Integer in Java is parseInt() of String class.
See the NSString Class Reference.
NSString *string = @"5"; int value = [string intValue]; How about
[@"7" intValue]; Additionally if you want an NSNumber you could do
NSNumberFormatter *numberFormatter = [[NSNumberFormatter alloc] init]; [numberFormatter numberFromString:@"7"]; If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
