我不会说这是从NSString中删除不需要的字符的最好方法，但我这样做了......而且很棒。

NSString * str = @"your string";
NSMutableString * newString;
int j = [str length];
for (int i=0; i<j; i++) {       
    if (([str characterAtIndex:i] >=65 && [str characterAtIndex:i] <=90) || ([str characterAtIndex:i] >=97 && [str characterAtIndex:i] <=122) ||[str characterAtIndex:i] == 32 ) {
        [newString appendFormat:@"%c",[str characterAtIndex:i]];
    }               
}

//([str characterAtIndex:i] >=65 && [str characterAtIndex:i] <=90) this is ASCII limit for A-Z
//([str characterAtIndex:i] >=97 && [str characterAtIndex:i] <=122) this is ASCII limit for a-z
//and [str characterAtIndex:i] == 32 is for space.

现在，打印新字符串

NSLog(@"%@",newString);

让我知道它是否在为你而战！

谢谢！
