I have included more code below and also an image of the result which shows the result I get, which is the same result I got without the subclassing, with just plain labels. In the first 3 rows the labels seem to cover up the button altogether, and in the 4th row there are no labels, and notice that the button #2 is indented on the 4th row. What's going on.
This code only applies to the first of the four rows, but the other 3 rows are similar.
self.cardList = [NSMutableArray arrayWithCapacity:0];
self.yHonorsOrigin = 100;
self.xHonorsOrigin = 100;
self.xHonorsStep = 40.0;
self.xHonorsCurrent = self.xHonorsOrigin;
for( int x=0;x<[cards length]; x++ ){
[cards substringWithRange:NSMakeRange(x,1)];
UIButton *b= [UIButton buttonWithType:UIButtonTypeRoundedRect];
self.xHonorsCurrent += self.xHonorsStep;
[b setTitle:[cards substringWithRange:NSMakeRange(x,1)] forState:UIControlStateNormal];
[b setTitle:#" " forState:UIControlStateDisabled];
[b setFrame:CGRectMake(self.xHonorsCurrent, self.yHonorsOrigin, 20, 20)];
[b setEnabled:YES];
[b setUserInteractionEnabled:YES];
[self.view addSubview:b];
[b addTarget:self action:#selector(spadeButtonPressed:) forControlEvents:UIControlEventTouchUpInside];
self.xHonorsCurrent = self.xHonorsOrigin + self.xHonorsStep/2;
for( int x=0;x<[cards length]-1; x++ ){
self.xHonorsCurrent += self.xHonorsStep;
UILabel *lab = [self valueForKey:#"theSuit" ];
lab.text = #"\u2660";
//lab.tintColor = [UIColor clearColor];
lab.center = CGPointMake(self.xHonorsCurrent, self.yHonorsOrigin);
[self.view addSubview:lab];
}
}
}

I have attempted to subclass the UILabel class using BDBoundedLabel, but am throwing an exception that "subclassed label class is not key value coding-compliant for the key theSuit." Please help.
BDBoundedLabel.m
#import "BDBoundedLabel.h"
#implementation BDBoundedLabel
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
}
return self;
}
- (void)drawTextInRect:(CGRect)rect{
CGContextRef context=UIGraphicsGetCurrentContext();
CGContextStrokeRect(context, CGRectInset(self.bounds, 1, 1));
[super drawTextInRect:CGRectInset(rect, 5.0, 5.0)];
}
#end
viewController.h
#import <UIKit/UIKit.h>
#import "BDViewController.h"
#import "BDBoundedLabel.h"
#interface BDnameViewController : UIViewController{
IBOutlet BDBoundedLabel* theSuit;
}
viewController.m
- (void)viewDidLoad
{
[super viewDidLoad];
self.cardList = [NSMutableArray arrayWithCapacity:0];
self.yHonorsOrigin = 100;
self.xHonorsOrigin = 100;
self.xHonorsStep = 40.0;
self.xHonorsCurrent = self.xHonorsOrigin;
// Do any additional setup after loading the view.
self.xHonorsCurrent = self.xHonorsOrigin + self.xHonorsStep/2;
for( int x=0;x<[cards length]-1; x++ ){
self.xHonorsCurrent += self.xHonorsStep;
UILabel *lab = [BDBoundedLabel valueForKey:#"theSuit" ];
lab.text = #"\u2660";
lab.center = CGPointMake(self.xHonorsCurrent, self.yHonorsOrigin);
[self.view addSubview:lab];
}
}

Answer 1

setValue:forKey: and valueForKey: will use the accessors methods (setter and getter), so you need to create them. Declare a property:
#property(nonatomic,assign) BDBoundedLabel* theSuit;
Also, like stated by Benjamin you are calling valueForKey: on a class object, maybe you meant to call the method with self as target, this way:
UILabel *lab = [self valueForKey:#"theSuit" ];
// Equivalent of lab= self.theSuit

Answer 2

Your code does not make any sense. You are performing KVO on a class object, which is almost never done. For most cases, KVO is only ever used on instances of a class, which is not what you are doing here.
Please try and clarify what you are trying to do.
