Question

i have been looking around and haven\'t quite found anything on doing this and am not sure if its even possible, but this is what i am trying to achieve. please note, i am g

Answer 1

sorry guys & gals, i wound up figuring this out. the "setValue:forKeyPath:" turned out to be what i needed. so for an example...

example.h

@property (strong, nonatomic) UILabel *label1;
@property (strong, nonatomic) UILabel *label2;
@property (strong, nonatomic) UILabel *label3;

example.m

@synthesize label1, label2, label3;

- (void)someMethod:(int)labelVarInt {

[self setValue:[NSString stringWithFormat:@"This is Label %i", labelVarInt] forKeyPath:[NSString stringWithFormat:@"label%i.text", labelVarInt]];

}

hope this helps anyone else who is needing to do anything similar.

If the case is simply indexed strings, you should probably use an array, otherwise you are looking for introspection (take a look at this question).

Answer 3

I think you need to store the labels in an NSArray, then you could access the labels by index.

Another approach is getting the labels using KVC.
