如何从 NSDictionary 到 NSArray 获取数据

Answer 1

只贴代码，运行输出

NSURL *url = [NSURL URLWithString:@"l"];
NSURLRequest *request = [[NSURLRequest alloc] initWithURL:url cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:60.0f];
NSError *error = [[NSError alloc] init];
NSURLResponse *response = [[NSURLResponse alloc] init];
NSData *responeData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response
error:&error];
NSDictionary *jsonToDictionary = [NSJSONSerialization JSONObjectWithData:responeData
options:0
error:&error];
NSDictionary *dictionaryData = [jsonToDictionary objectForKey:@"weatherinfo"]; NSLog(@"%@",dictionaryData);
