Question:
I have an NSString like so:
@"200hello"
or
@"0 something"
What I would like to be able to do is take the first occuring number in the NSString and convert it into an int.
So that @"200hello" would become int = 200.
and @"0 something" would become int = 0.
Answer1:
int value;
BOOL success =[[NSScanner scannerWithString:@"1000safkaj"] scanInteger:&value];
If the number is not always at the beginning:
NSCharacterSet* nonDigits =[[NSCharacterSet decimalDigitCharacterSet] invertedSet];
int value =[[@"adfsdg1000safkaj" stringByTrimmingCharactersInSet:nonDigits] intValue];
Answer2:
If the int value is always at the beginning of the string, you can simply use intValue.
NSString*string=@"123hello";
int myInt =[string intValue];
