【iPhone代码片段之五】读取URL内容 .

读取URL内容，核心代码如下：

self.url = tfURL.text;
    if([self.url length]<=0){
        self.url = @"http://www.baidu.com";
    }
    NSURL *nsURL = [NSURL URLWithString:self.url];

    NSStringEncoding enc = CFStringConvertEncodingToNSStringEncoding(kCFStringEncodingGB_18030_2000);

    NSError *error;
    NSString *content = [NSString stringWithContentsOfURL:nsURL
                                                 encoding:enc
                                                    error:&error];
    [self.tvURLContent setText:content];
