Answer 1

裝載的plist後，你只需訪問不同的密鑰：

NSDictionary *plist = [NSDictionary dictionaryWithContentsOfFile:filename]; 

NSDictionary *mainCategories = [plist objectForKey:@"MainCategories"]; 
NSArray *categoryNames = [mainCategories objectForKey:@"CategoryNames"]; 
NSArray *images = [mainCategories objectForKey:@"Images"]; 

Answer 2

NSString *plistFilePath = [[NSBundle mainBundle] pathOfResource:@".." ofType:@"plist"]; 
NSDictionary *mainCategories = [NSDictionary dictionaryWithContentsOfFile:plistFilePath]; 

NSArray *categoryNames = [mainCategories objectForKey:@"CategoryNames"]; 
NSArray *categoryImages = [mainCategories objectForKey:@"Images"];
