Converting Unichar to Int Problem
I've got a strange problem trying to convert from unichar to int:
I have a String containing a few numbers, like @"12345". This numbers I want to save individually, meaning I want 5 numbers, 1, 2, 3, ... . Now, while
NSLog(@"Value: %C", [myString characterAtIndex:0]);
returns
Value: 1
This:
NSLog(@"Value: %@", [NSNumber numberWithUnsignedChar:[myString characterAtIndex:0]]);
returns
Value: 49
I would really appreci开发者_开发问答ate some help, Fabian
In the code above, you're getting exactly what you're asking for; the numeric value of the character '1' is 49, and you're creating an NSNumber from that.
If what you want is 1, then you can can take advantage of the fact that the digits 0-9 are laid out in order in the ASCII/UTF-8 tables and subtract an appropriate value from the unichar you receive.
Try out this code snippet to get you started in the right direction:
NSString *s = @"0123456789";
for (int i = 0; i < [s length]; i++) {
NSLog(@"Value: %d", [s characterAtIndex:i]);
}
