iOS development tips-using and customizing switch controls (Uiswitch)

1. Initialize the load to the view interface

(Swift)

Import UIKitclass Viewcontroller:uiviewcontroller {    // 1. Create a property of type Uiswitch    var mainswitch:uiswitch!        override//0)) View.addsubview (Mainswitch)}}       

(OBJECTIVE-C)

#import"ViewController.h"@interface Viewcontroller () // 1. Create a property of type Uiswitch@property (Nonatomic, strong) Uiswitch *mainswitch; @end  @implementation  viewcontroller-(void// 2. Create switch Self.mainswitch = [[Uiswitch alloc] Initwithframe:cgrectmake (100, 100, 0, 0)]; [Self.view AddSubview:self.mainSwitch];}  @end             

2. Setting the switch status

(Swift)

Mainswitch.seton (true)

(OBJECTIVE-C)

[Self.mainswitch Seton:yes];

3. Determine the switching status

(Swift)

If mainswitch.on{/* * */else/*/    }      

(OBJECTIVE-C)

If ([Self.mainswitch isOn]) {    NSLog (@ "The switch is on.") else {NSLog (@ "Theswitch is off.") );}

4. Add Event Listener

(Swift)

Mainswitch.addtarget (Self, Action:"switchischanged:", forControlEvents:. valuechanged) func switchischanged (sender:uiswitch) {println ("sender is = \ (sender)") if s ender.on{println ("Theswitch is turned on")} else {println ("Theswitch is Turne D off")}}                

(OBJECTIVE-C)

[Self.mainswitch addtarget:self Action: @selector (switchischanged:) forcontrolevents:uicontroleventvaluechanged]; - (void) Switchischanged: (Uiswitch *) Paramsender {NSLog (@ "Sender is =%@", Paramsender); if ([Paramsender isOn]) {NSLog (@ "Theswitch is turned on." ); } Else {NSLog (@ "Theswitch is turned off.") ); }}

5. Customizing the Switch UI

/* */mainswitch.tintcolor = uicolor.redcolor ()/**/Mainswitch.ontintcolor =  Uicolor.browncolor ()/**/Mainswitch.thumbtintcolor = Uicolor.greencolor ()
