Question

I try to scan a string and divide it to separate strings.
My code is:

#import <Foundation/Foundation.h>
NSArray *wordsArray;
int amount;
char input[80];
int main (int argc, const char * argv[])
{

    @autoreleasepool {
       NSString *stra=[[NSString alloc] initWithString:@""];        

    //  stra=@"this is my sentence";
       NSLog(@"Please Enter a sentence!");
       scanf("%s",&input);
       stra=[NSString stringWithCString:input encoding:NSASCIIStringEncoding];
    //   NSLog(@"words: %@",str);

         wordsArray = [stra componentsSeparatedByString:@" "];
         amount= [wordsArray count];
         NSLog(@"Number of Shows : %d", amount);

        for (int i=0; i<amount; i++) 
        {
            NSString *subString = [wordsArray objectAtIndex:i];
            NSLog(@"\n %@",[subString uppercaseString]);
        }


    }
    return 0;
}

On input: “Test1 test2 test3”

I get: Test1

The code doesn’t consider spaces. How do i scan the hall string?

Answer 1

A reason this isn’t working is that scanf doesn’t have a size of string to look for, so it is stopping at the first whitespace. Another method you can use is fgets() for the input.
