copied!<p>This is a basic example that I know can be simplified, but for testing sake, I would like to do this in such a way. I want to set a variable based on an appending string (the variables "cam0" and "pos1" are already declared in the class). The appending string would essentially be an index, and i would iterate through a loop to assign cameras (cam0, cam1..) to different positions (pos0, pos1..).</p> <p>cam0 is defined as an UIImageView<br> pos1 is defined as a CGRect</p> <p>This works for a NSString Variable named coverIndex:</p> <pre><code>NSString* text = [[NSString alloc] initWithString:@""]; NSLog(@"%@",(NSString *)[self performSelector:NSSelectorFromString([text stringByAppendingString:@"coverIndex"])]); </code></pre> <p>The correct string that I set for coverIndex was logged to the Console.</p> <p>Now back to my UIImageView and CGRect. I want this to work.</p> <pre><code>NSString* camText = [[NSString alloc] initWithString:@"cam"]; NSString* posText = [[NSString alloc] initWithString:@"pos"]; [(UIImageView *)[self performSelector:NSSelectorFromString([camText stringByAppendingString:@"0"])] setFrame:(CGRect)[self performSelector:NSSelectorFromString([posText stringByAppendingString:@"1"])]]; </code></pre> <p>My error is "Conversion to non-scalar type requested"</p> <p>This is the only way I found to do this sort of thing (and get the NSLog to work), but I still believe there is an easier way.</p> <p>Thank you so much for any help :)</p>
