retrieving integer value from the UITextField into a NSInteger variable

问题

UITextField *textField;
NSInteger intRollNumber;

I want to take rollNumber as input from the textField and store the value into intRollNumber .

How i do that? Because I am unable to convert the string into integer.

回答1:

Like this?

NSString *str = [textField text]
int RollNumber = [str intValue];

回答2:

See the text property and integerValue.
