感谢你..
代码如下

NSURLConnection *myConnection = [NSURLConnection connectionWithRequest:request delegate:self];
[myConnection start];
[super viewDidLoad];
}
- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
[dataWebService setLength:0];
}
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
[dataWebService appendData:data];
}
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
Nsstring *responseString = [[Nsstring alloc] initWithData:dataWebService encoding:NSUTF8StringEncoding];
NSLog(@\"Response: %@\",responseString);
[responseString release];
[dataWebService release];
}
- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
NSLog(@\"Error during connection: %@\",[error description]);
}
解决方法
您不应该“ 1”请求类型为NSMutableURLRequest的实例。
字符串URL中的前导空格。
使用以下代码。
NSMutableURLRequest *request = [[NSMutableURLRequest requestWithURL:[NSURL URLWithString:@\"http://www.googleapis.com/customsearch\"]];
