检查 self.weatherData 时，即使“数据”中有数据，我什么也得不到。这是我的功能：
- (void)handleNetworkResponse:(NSData *)myData
{
//NSMutableDictionary *data = [NSMutableDictionary dictionary];
NSMutableDictionary *data = [[NSMutableDictionary alloc] init];
// now we'll parse our data using NSJSONSerialization
id myJSON = [NSJSONSerialization JSONObjectWithData:myData options:NSJSONReadingMutableContainers error:nil];
// typecast an array and list its contents
NSDictionary *jsonArray = (NSDictionary *)myJSON;
// take a look at all elements in the array
for (id element in jsonArray) {
id key = [element description];
id innerArr = [jsonArray objectForKey:key];
NSDictionary *inner = (NSDictionary *)innerArr;
if ([inner conformsToProtocol:@protocol(NSFastEnumeration)]) {
for(id ele in inner) {
id innerKey = [ele description];
[data setObject:[[inner valueForKey:innerKey] description] forKey:[ele description]];
}
}
else {
[data setObject:[inner description] forKey:[element description]];
}
}
NSLog([data description]);
self.weatherData = data;
}
但是，当检查 self.weatherData 时，即使“数据”中有数据，我什么也得不到。
