Addobject NSMutableArray to a NSDictionary

Question

I am trying to add an NSMutableArray to an NSDictionary but I get this issue when show NSDictionary in log:

)' of class '__NSCFArray'.  Note that dictionaries and arrays in
property lists must also contain only property valúes.

This is the code I use to create the NSMutableDictionary

NSMutableDictionary *training = [[NSMutableDictionary alloc] init];
[training setObject:[NSNumber numberWithInt:eltiempo] forKey:@"tiempototal"];
[training setObject:[NSNumber numberWithFloat:totalkm] forKey:@"distanciatotal"];
[training setObject:[NSNumber numberWithInt:(int)(velocidadmedia/60)] forKey:@"velocidadmedia"];
[training setObject:[NSString stringWithFormat:@"%2d:%02d min/km"] forKey:@"fecha"];
[training setObject:posiciones forKey:@"posiciones"];

Where posiciones is the array I want to add. I save this dictionary in an array in order to save it in User Defaults. But as I have this problem the NSDictionary is no created.

Thanks for you help.

Answer 1

您将其添加到数组就好了^^您要写入一个plist（根据错误），并且posiciones包含不能在plist中使用的非plist类型

Answer 2

Pedro Piñera Buendia,

Try this code,

NSMutableDictionary *woRows = [[NSMutableDictionary alloc] init];
NSMutableArray *workOrders = [[NSMutableArray alloc] init];

[woRows  setValue:[workOrders objectAtIndex:0] forKey:@"somekey"];
[woRows setValue:[workOrders objectAtIndex:1] forKey:@"somekey"];
[woRows setValue:[workOrders objectAtIndex:2] forKey:@"somekey"];
