推荐答案
类似的方法应该起作用:
Something like this should work:
- (void)expandDictionary:(NSDictionary *)dict into:(NSMutableArray *)output
{
for(id key in [dict allKeys])
{
id value = [dict valueForKey:key];
if([value isKindOfClass:[NSDictionary class]])
{
[self expandDictionary:value into:output];
}
else
{
[output addObject:[value stringValue]];
}
}
}
- (NSArray *)expandDictionary:(NSDictionary *)dictionary
{
NSMutableArray *output = [NSMutableArray array];
[self expandDictionary:dictionary into:output];
return output;
}
