Handling multiple UISwitch controls in a table view without using tag property

Well i want to ask how can i configure 7 UISwitches on one UIview? I place the switches with interface builder and then i want to manage them through code. What is the best way of managing this. Here is my .h so far

#import <UIKit/UIKit.h>

@interface searchEditViewController : UIViewController{

    UISwitch *switchOne;
    UISwitch *switchTwo;
    UISwitch *switchFor;
    UISwitch *switchFive;
    UISwitch *switchSix;
    UISwitch *switchSeven;


}

@property(nonatomic,retain)UISwitch *switchOne;
@property(nonatomic,retain)UISwitch *switchTwo;
@property(nonatomic,retain)UISwitch *switchThree;
@property(nonatomic,retain)UISwitch *switchFour;
@property(nonatomic,retain)UISwitch *switchFive;
@property(nonatomic,retain)UISwitch *switchSix;
@property(nonatomic,retain)UISwitch *switchSeven;
-(IBAction)toggleButtonPressed:(id)sender;
@end

I want to make one action method toggleButtonPressed that will take care the seven of them

Answer 1

Create one action for all UISwitch objects (I guess this is toggleButtonPressed). In this method now you can know which UISwitch was triggered:

-(IBAction)toggleButtonPressed:(id)sender{
    UISwitch *switchObj = (UISwitch*)sender;
    if (switchObj == self.switchOne){
        // do stuff
    }

    if (switchObj == self.switchTwo){
        // do stuff
    }

//    switch(switchObj.tag){
//        case 1:
//            // do stuff
//            break;
//        case 2:
//            // do stuff
//            break;
//    }
}

Edit. You can set tag property to some value (from 1 to 7) and change if-statement to switch-case.

Answer 2

@beryllium, your way does work but you might want to try something a little more elegant.

Instead, tag each switch and then instead of if-then use switch-case as you appear to have commented out.

Here's an example, note that kUIActivityIndicatorViewStyleWhiteLarge is actually a constant I created and assigned a value #define kUIActivityIndicatorViewStyleWhiteLarge 1

- (IBAction)setSpinnerType:(UISwitch *)sender
{
    // switch based on tag value
    // turn other two switches off
    switch (sender.tag) {
        case kUIActivityIndicatorViewStyleWhiteLarge:
            self.spinner.activityIndicatorViewStyle = UIActivityIndicatorViewStyleWhiteLarge;
            [sender setOn:YES animated:YES];
            [self.whiteSwitch setOn:NO animated:YES];
            [self.graySwitch setOn:NO animated:YES];
            break;
        case kUIActivityIndicatorViewStyleWhite:
            self.spinner.activityIndicatorViewStyle = UIActivityIndicatorViewStyleWhite;
            [self.whiteLargeSwitch setOn:NO animated:YES];
            [sender setOn:YES animated:YES];
            [self.graySwitch setOn:NO animated:YES];
            break;
        case kUIActivityIndicatorViewStyleGray:
            self.spinner.activityIndicatorViewStyle = UIActivityIndicatorViewStyleGray;
            [self.whiteLargeSwitch setOn:NO animated:YES];
            [self.whiteSwitch setOn:NO animated:YES];
            [sender setOn:YES animated:YES];
            break;
        default:
            break;
    }
}

If you want to do it your way, that's OK but again less optimal. However if you do, the code:

UISwitch *switchObj = (UISwitch*)sender;
    if (switchObj == self.switchOne){

is redundant. instead you can wrote the following:

-(IBAction)toggleButtonPressed:(UISwitch *)sender{
    // UISwitch *switchObj = (UISwitch*)sender;
    if (sender == self.switchOne){
        // do stuff
    }

I hope that helps.

I created an app to test UIActivityIndicatorView styles on different coloured backgrounds and it uses sliders and switches. Here the url if anyone wants to see the app with IB components:
