for循環問題，Objective-C

Question

對Objective-C來說基本上是新的。這是我的問題。 如何將字符串的單個字符發送到for循環並在for循環中輸出每個字符？

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); 
}
