Question

我发现这有点反直觉。如果我想做相当于scanf并将该输入分配给变量或数组，我该怎么做，然后在objective-c中打印它。

您可以使用NSMutableArray并循环使用NSString测试中的每个字符我已经测试了它..

NSMutableArray *arr = [[NSMutableArray alloc] init];
NSString *str = [NSString stringWithFormat:@"masdasdada"];
int length = [str length];

for (int i = 0 ; i < length; i++) {
    NSLog(@"%hu",[str characterAtIndex:i]);

    unichar utf8char = [str characterAtIndex:i]; 
    char chars[2];
    int len = 1;

    if (utf8char > 127) {
        chars[0] = (utf8char >> 8) & (1 << 8) - 1;
        chars[1] = utf8char & (1 << 8) - 1; 
        len = 2;
    } else {
        chars[0] = utf8char;
    }

    NSString *string = [[NSString alloc] initWithBytes:chars
                                                length:len 
                                              encoding:NSUTF8StringEncoding];

    NSLog(@"%@",string);
    [arr addObject:[NSString stringWithFormat:@"%@",string]];
}

for (NSMutableString *s in arr) {
    NSLog(@"%@",s);
}
