Objective

In the previous blog post, we introduced how to implement Uiswitch, and we introduced how to customize Uiswitch.

Body

1, we first implement a uiswitch on the interface.

A> in the controller. m file, add a Uiswitch property.

1 @interface moboviewcontroller ()

2 @property (nonatomic, Strong) Uiswitch *Mainswtich;

3 @end

B> instantiates a uiswitch in the-(void) Viewdidappear method and adds it to the interface.

 

  1 -(void  ) Viewdidappear: (BOOL) animated   2      {  3     5  Self.mainswtich = [[Uiswitch alloc ]initwithframe:cgrectmake (100 , 100 , Span style= "color: #800080;" >0 , 0  )];//instantiation with x100,y100  Span style= "color: #008080;" > 6   7   [Self.view addSubview:self.mainSw   Tich];  Add to Interface 8}  

2. Custom Switch Color:

We first press CMD to enter the Uiswitch header file. See Three properties:

Uicolor *ontintcolor//color on Open

Uicolor *tintcolor//Off color

Uicolor *thumbtintcolor//Switch button color

Below we come to define, add the following code in-(void) Viewdidappear:

1Self.mainSwtich.thumbTintColor = [Uicolor colorwithred: (151./255.0) Green: (Bayi./255.0) Blue: (229./255.0) Alpha:1];2     3Self.mainSwtich.tintColor = [Uicolor colorwithred: (Wuyi./255.0) Green: (181./255.0) Blue: (229./255.0) Alpha:1];4     5Self.mainSwtich.onTintColor = [Uicolor colorwithred: (Wuyi./255.0) Green: (181./255.0) Blue: (229./255.0) Alpha:1];

Note: We have used the Uicolor class of ColorWithRed:green:blue: Method, the color value of this method is floating point type, so must use "color value./255.0", the color value is best with one behind. , look professional a little ~ ~ ~

In addition the color value conversion of God horse, there is a website support Online conversion: http://www.atool.org/colorpicker.php

3. We will set the default switch state of Uiswitch:

This is simple, add the following code in the-(void) Viewdidappear method:

1 [Self.mainswtich seton:yes animated:yes];

4, monitor the switch state of Uiswitch:

1 [Self.mainswtich addtarget:self Action: @selector (switchischanged:) forControlEvents: Uicontroleventvaluechanged];

Then, under-(void) Viewdidappear, implement the Switchischanged method:

1- (void) switchischanged: (Uiswitch *) Paramsender2 {3     if([Self.mainswtich isOn]) {4NSLog (@"Switch is on");5     }6     Else{7NSLog (@"Switch is off");8     }9}

Cmd+r run a bit, click on the switch, watch the console can see the results of the console printing!
