1, segmented Select control when using multiple buttons you can choose to use the segmented selection control

2. Switch button

3, sliding bar

Today, it's all about Uicontrol. The sub-categories include the previously learned buttons

1. Segment Selection Control

Segment selection control you need to give him an array of headings when you start the initialization.

Uisegmentedcontrol *segment = [[Uisegmentedcontrol alloc]initwithitems:@[@ "Entertainment", @ "military", @ "technology"];

Segment.frame = CGRectMake (100, 100, 200, 40);

Sets whether to remember the previous button

Segment.momentary = YES;

[Segment Addtarget:self Action: @selector (segmentaction:) forcontrolevents:uicontroleventvaluechanged];

[Self.view addsubview:segment];

Switch button

The switch button generally needs to record the user set status 1, can use the interface provided by the background to set the switch button switches (can be synchronized between different devices state (information)) 2, save the settings locally

Uiswitch *switchbutton = [[Uiswitch alloc]initwithframe:cgrectmake (100, 200, 50, 40)];

[Switchbutton addtarget:self Action: @selector (switchaction:) forcontrolevents:uicontroleventvaluechanged];

Nsuserdefaults *userdefaults = [Nsuserdefaults standarduserdefaults];

Set the default state of switch

Switchbutton.on = [Userdefaults boolforkey:@ "IsOn"];

Sets the color of the track when the switch button is open

Switchbutton.ontintcolor = [Uicolor Redcolor];

Set the track color when the switch button is off

Switchbutton.tintcolor = [Uicolor Greencolor];

Sets the color of the switch button small circle

Switchbutton.thumbtintcolor = [Uicolor Yellowcolor];

[Self.view Addsubview:switchbutton];

Sliding Bar

UISlider *slider = [[UISlider alloc]initwithframe:cgrectmake (100, 300, 200, 10)];

[Slider addtarget:self action: @selector (slideraction:) forcontrolevents:uicontroleventvaluechanged];

Set the minimum value of the slider bar

Slider.minimumvalue = 1;

Set the maximum value of the slider bar

Slider.maximumvalue = 10;

Set the default position of the slider bar

Slider.value = 1;

Sets the track color for the minimum value of the slider bar

Slider.minimumtracktintcolor = [Uicolor Redcolor];

Track color of slider Max

Slider.maximumtracktintcolor = [Uicolor Purplecolor];

The color of the small circle

Slider.thumbtintcolor = [Uicolor Yellowcolor];

[Self.view Addsubview:slider];

}

Trigger when the finger touches the screen

-(void) Touchesbegan: (Nsset *) touches withevent: (Uievent *) event

{

if ([[Nsuserdefaults standarduserdefaults] boolforkey:@ "IsOn"]!=no) {

Get Touch events

Uitouch *touch = [touches anyobject];

Get the point of touch

Cgpoint touchPoint = [Touch LocationInView:self.view];

When the animation does not execute, call the inside method

if (animationview.isanimating! = YES) {

Animationview.alpha = 1.0;

Animationview.center = TouchPoint;

[Animationview startanimating];

}

}

}

The finger moves on the screen to trigger

-(void) touchesmoved: (Nsset *) touches withevent: (Uievent *) event

{

if ([[Nsuserdefaults standarduserdefaults] boolforkey:@ "IsOn"]! = NO) {

Get Touch events

Uitouch *touch = [touches anyobject];

Get the point of touch

Cgpoint touchPoint = [Touch LocationInView:self.view];

Animationview.center = TouchPoint;

}

}

Trigger when finger leaves the screen (touch end)

-(void) touchesended: (Nsset *) touches withevent: (Uievent *) event

{

if ([[Nsuserdefaults standarduserdefaults] boolforkey:@ "IsOn"]! = NO) {

[UIView Animatewithduration:2 animations:^{

Animationview.alpha = 0.0;

} completion:^ (BOOL finished) {

[Animationview stopanimating];

}];

}

}

-(void) Slideraction: (UISlider *) sender

{

NSLog (@ "%0.2f", Sender.value);

Animationview.animationduration = Sender.value;

}

-(void) Switchaction: (Uiswitch *) sender

{

NSLog (@ "%d", Sender.ison);

Nsuserdefaults *userdefaults = [Nsuserdefaults standarduserdefaults];

[Userdefaults setBool:sender.isOn forkey:@ "IsOn"];

[Userdefaults Synchronize];

}

-(void) Segmentaction: (Uisegmentedcontrol *) sender

{

NSLog (@ "%ld", Sender.selectedsegmentindex);

Switch (sender.selectedsegmentindex) {

Case 0:

Bgview.backgroundcolor = [Uicolor Browncolor];

Break

Case 1:

Bgview.backgroundcolor = [Uicolor Whitecolor];

Break

Case 2:

Bgview.backgroundcolor = [Uicolor Lightgraycolor];

Break

Default

Break

}

}

-(void) didreceivememorywarning {

[Super didreceivememorywarning];

Dispose of any resources the can be recreated.
