Easy to use UISwitch

IBOutlet UISwitch --> value changed event
(UISlider也是類似此方式)

//

//  PowerBankViewController.h

@interface PPowerBankViewController : UIViewController {

IBOutlet UISwitch *aSwitch;

}

@property (nonatomic, retain) IBOutlet UISwitch *aSwitch;

-(IBAction)onSwitch:(id)sender;

//

//  PowerBankViewController.m

@synthesize aSwitch;

-(IBAction)onSwitch:(id)sender

{

aSwitch = (UISwitch *)sender;

NSLog(@"in onSwitch");

if ([aSwitch isOn] == YES) {

NSLog(@"[aSwitch isOn] == YES");

}

else{

NSLog(@"[aSwitch isOn] == NO");

}

}

- (void)viewDidLoad {

aSwitch = [[UISwitch alloc] init];

}

- (void)dealloc {

[aSwitch release];

    [super dealloc];

}
