you can add any object to NSMutableArray using the addObject method like this:
您可以使用 addObject 方法将任何对象添加到 NSMutableArray，如下所示：
NSDictionary *aDic= [NSDictionary dictionaryWithObjectsAndKeys:
@"Carlos", @"name",
@"Jimenez", @"lastName", nil];
//On initialization
NSMutableArray *aArr = [NSMutableArray arrayWithObjects:aDic,nil];
//After initialization
NSMutableArray *aArr2 = [NSMutableArray array]; [aArr2 addObject:aDic];
Hope it helps you!
希望对你有帮助！
