iPhone开发:UIScrollView分页算法 [iPhone开发]

post by 朦朧中的罪惡 / 2010-2-22 20:09 Monday

在使用 UIScrollView 分页的时候我们如何确定当前是第几页？

首先需要开启分页设置

scrollView.pagingEnabled = YES;

然后我们在委托的类上实现以下方法

- (void) scrollViewDidScroll:(UIScrollView *)sender {
        // 得到每页宽度
        CGFloat pageWidth = sender.frame.size.width;
        // 根据当前的x坐标和页宽度计算出当前页数
        int currentPage = floor((sender.contentOffset.x - pageWidth / 2) / pageWidth) + 1;
}

iPhone开发:通过NSURLRequest获得服务器返回的http header和http status [iPhone开发]

post by 朦朧中的罪惡 / 2010-2-21 12:22 Sunday

同步访问时的取法

NSURL *url = [NSURL URLWithString:@"http://www.test.com"];
NSURLRequest *request = [NSURLRequest requestWithURL: url];
NSHTTPURLResponse *response;
[NSURLConnection sendSynchronousRequest: request returningResponse: &response error: nil];
if ([response respondsToSelector:@selector(allHeaderFields)]) {
    // 取得所有的请求的头
    NSDictionary *dictionary = [response allHeaderFields];
    NSLog([dictionary description]);
    // 取得http状态码
    NSLog(@"%d",[response statusCode]);

}

异步访问时则要实现委托的一个方法

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response {
    // 注意这里将NSURLResponse对象转换成NSHTTPURLResponse对象才能去
    NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse*)response;
    if ([response respondsToSelector:@selector(allHeaderFields)]) {
        NSDictionary *dictionary = [httpResponse allHeaderFields];
        NSLog([dictionary description]);
        NSLog(@"%d",[response statusCode]);

    }
}
