ios - subString emution ios

Question

当我尝试提取字符串 :"hello [hihi] wold [hehe]"到数组 {"hello ","[hihi]","wold","[hehe]",[hehe]"}

-(void)getString:(NSString *)emution
{
    int n=[emution length];
    int x=0,y=0,i=0;
    char temp;
    while (true) {
        temp=[emution characterAtIndex:i];
        if(temp == '[')
        {
            x=i;
        }else
        {
            if(temp==']')
            {
                y=i+1;
                NSLog(@"x: %d , y:%d",x,y);
                NSString *sub=[emution substringWithRange:NSMakeRange(x, y)];
                NSLog(@"here:%@",sub);
                x=y;
                sub=nil;
            }
            if(i>=n-1)
            {break;}
        }
        i++;
    }
}

结果这不是真的，我不知道，但是当我尝试用 java 编写代码时，这是真的

我想你想要的是:

NSArray *array = [emution componentsSeparatedByString:@" "];

此外，我注意到结束循环 if(i>=n-1) 的检查应该在您递增 i 之后，而不是在 else 语句中.
