小编jsa*_*msa的帖子

我想将逗号分隔值拆分成对:

>>> s = '0,1,2,3,4,5,6,7,8,9'
>>> pairs = # something pythonic
>>> pairs
[(0, 1), (2, 3), (4, 5), (6, 7), (8, 9)]

会是什么Python的#什么样子呢？

你如何检测和处理一组奇数的字符串？

我真的很难弄清楚为什么我的Web服务调用充斥着垃圾数据.

我有一个UITableViewController调用Web服务,也充当NSURLConnectionDelegate.

这是感兴趣的委托方法,请注意NSLog语句.

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
    NSLog(@"data %@", [[NSString alloc] initWithUTF8String: [data bytes]]);
    NSLog(@"before %@", [NSString stringWithUTF8String: self.rawData.bytes]);
    [self.rawData appendData:data];
    NSLog(@"after %@", [NSString stringWithUTF8String: self.rawData.bytes]);
}

以下是经过多次尝试后生成的日志:
