[英]how to handle the responseString from json output and parse it
I am using the following code and i am getting a response string in JSON. 我正在使用以下代码,并且在JSON中获取响应字符串。 I don't know how to parse it.
我不知道该怎么解析。 What should I do next if I want to call any method on JSON output
如果要在JSON输出上调用任何方法,下一步该怎么办
// source code // 源代码
- (void)viewDidLoad
{
[super viewDidLoad];
dataWebService = [[NSMutableData data] retain];
NSMutableURLRequest *request = [[NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"https://www.googleapis.com/customsearch/v1?key=AIzaSyDzl0Ozijg2C47iYfKgBWWkAbZE_wCJ-2U&cx=017576662512468239146:omuauf_lfve&q=lectures&callback=handleResponse"]]retain];
NSURLConnection *myConnection = [NSURLConnection connectionWithRequest:request delegate:self];
[myConnection start];
}
- (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]);
}
