我想从我的字符串中打开一个网址我的字符串已经有了我想要显示的网址 UIWebView

myString=http://maps.google.com/maps?zoom=8&sensor=false&lci=transit&layer=traffic&saddr=1.31224,103.865&daddr=1.310664,103.857132

NSString *urlString = [myString absoluteString];
NSString *urlAddress =myString;// 
NSURL *url = [NSURL URLWithString:urlString ];

NSLog(@" url is %@",url); its null 
//URL Requst Object
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];


NSLog(@" url req  is %@",url);
//Load the request in the UIWebView.
[webe loadRequest:requestObj];

我收到了这个错误

平均而言,开发人员每天应编写多少行代码？

我想知道如何回答这个问题.

如何在iPhone的导航栏中添加搜索栏

这是显示搜索栏的代码,但我想把它放在导航栏中

sBar = [[UISearchBar alloc]initWithFrame:CGRectMake(0,10,320,30)];

sBar.delegate = self;

[self.view addSubview:sBar];
//[self.navigationItem.rightBarButtonItem addSubview:sBar];
//self.navigationItem.rightBarButtonItem=sBar;

有什么办法吗？
