    copied!<p>I made an program from a tutorial in ios 4 which was a checkbox. I had a friend who is starting to program in xcode for iphone. So, I gave him my codes so he can start. Turns out, he was trying to do the code himself in ios5 following the code I made for IOS4. He kept telling me that his didn't work and that he got a bunch of errors some as follows. So I would open my code and ran it on my updated xcode and it ran fine, no problem what so ever. The funny thing was when I got to his house and I looked at the code and played around with it. He was right. Trying to do the code from a new project in the new xcode with the new ios, the project would throw all sorts of errors. I posted some in the bottom. </p> <p>So, my question is this... why is this? does this have to do with the the way ios5 uses ARC and different properties?</p> <ul> <li>NSObject may not respond to initWithFrame</li> <li>Instance method - setImageForState not found(return type defaults to "id")</li> <li>instance method - addTarget:action:forControlEvents not found(return type default to id)</li> <li>MicheckBox may not respond to initWithFrame and some more</li> </ul> <p>my code is as follows have to png one called checkbox_ticked.png and a checkbox_not_ticked.png</p> <p>micheckbox.h</p> <pre><code>#import &lt;UIKit/UIKit.h&gt; @interface MICheckBox : UIButton { BOOL isChecked; } @property (nonatomic,assign) BOOL isChecked; -(IBAction) checkBoxClicked; @end </code></pre> <p>micheckbox.m</p> <pre><code>#import "MICheckBox.h" @implementation MICheckBox @synthesize isChecked; - (id)initWithFrame:(CGRect)frame { if (self = [super initWithFrame:frame]) { [self setImage:[UIImage imageNamed:@"checkbox_not_ticked.png"] forState:UIControlStateNormal]; [self addTarget:self action:@selector(checkBoxClicked)forControlEvents:UIControlEventTouchUpInside]; } return self; } -(IBAction) checkBoxClicked { if(self.isChecked ==NO) { self.isChecked =YES; [self setImage:[UIImage imageNamed:@"checkbox_ticked.png"] forState:UIControlStateNormal]; } else { self.isChecked =NO; [self setImage:[UIImage imageNamed:@"checkbox_not_ticked.png"]forState:UIControlStateNormal]; } } - (void)dealloc { [super dealloc]; } @end </code></pre> <p>MICheckBoxAppDelegate.h</p> <pre><code>#import &lt;UIKit/UIKit.h&gt; @interface MICheckBoxAppDelegate : NSObject &lt;UIApplicationDelegate&gt; { UIWindow *window; } @property (nonatomic, retain) IBOutlet UIWindow *window; @end </code></pre> <p>MICheckBoxAppDelegate.m</p> <pre><code>#import "MICheckBoxAppDelegate.h" #import "MICheckBox.h" @implementation MICheckBoxAppDelegate @synthesize window; - (void)applicationDidFinishLaunching:(UIApplication *)application { // Override point for customization after application launch MICheckBox *checkBox =[[MICheckBox alloc]initWithFrame:CGRectMake(5, 80, 150, 30)]; [checkBox setTitleColor:[UIColor blackColor] forState:UIControlStateNormal]; [checkBox setTitle:@"Checkbox" forState:UIControlStateNormal]; [window addSubview:checkBox]; [window makeKeyAndVisible]; } - (void)dealloc { [window release]; [super dealloc]; } @end </code></pre>
