for循环问题，Objective-C

Question

对Objective-C来说基本上是新的。这是我的问题。 如何将字符串的单个字符发送到for循环并在for循环中输出每个字符？

Answer 1

NSString *input = @"input string"; 

for (NSInteger i=0; i<[input length]; i++) 
{ 
    unichar c = [input characterAtIndex:i]; 
    NSLog(@"Character at %d: %c == %04x == %d",i,c,(int)c,(int)c); 
}
