ios – 从plist中检索数据

// Read plist from bundle and get Root Dictionary out of it
NSDictionary *dictRoot = [NSDictionary dictionaryWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"data" ofType:@"plist"]];

// Your dictionary contains an array of dictionary
// Now pull an Array out of it.
NSArray *arrayList = [NSArray arrayWithArray:[dictRoot objectForKey:@"catlist"]];

// Now a loop through Array to fetch single Item from catList which is Dictionary
[arrayList enumerateObjectsUsingBlock:^(id obj,NSUInteger index,BOOL *stop) {
    // Fetch Single Item
    // Here obj will return a dictionary
    NSLog(@"Category name : %@",[obj valueForKey:@"category_name"]);
    NSLog(@"Category id   : %@",[obj valueForKey:@"cid"]);
}];
