UIbutton与不同的时间段

我想要实现的是什么按钮

解决方法 我能够实现你正在进行的功能,下面是我的工作方式.

I created the design via storyboard and connected all the 9 button’s actions methods to a single Selector method,insIDe the action method with the help sender parameter we can get the selected buttons reference and use it.

- (IBAction)btnpressed:(UIbutton*)sender {/* Below for loop works as a reset for setting the default colour of button and to not select the same one twice*/for (UIbutton* button in buttons) {    [button setSelected:NO];    [button setBackgroundcolor:[UIcolor whitecolor]];    [button setUserInteractionEnabled:true];// [button setTitlecolor:[UIcolor blackcolor] forState:UIControlStatenormal];    [button setTitlecolor:[UIcolor blackcolor] forState:UIControlStateSelected];}NSInteger tag = sender.tag;        // Here we get the sender tag,which we can use for our needs. Also we can directly use the sender and get the Title or whatsoever needed./*Now below line works as a toggle for the button where multiple buttons can't be selected at the same time.*/sender.selected = ! sender.selected;      if(sender.selected){/* Here we set the color for the button and handle the selected function*/    [sender setSelected:YES];    [sender setUserInteractionEnabled:false];    [sender setBackgroundcolor:[UIcolor magentacolor]];}}

您还可以使用“sender.Layer”属性为按钮添加自定义图层.

整个代码添加在下面,

所有按钮的动作都需要连接到单个选择器方法,
– (IBAction)btnpressed：(UIbutton *)寄件人;

#import "VIEwController.h"@interface VIEwController ()@property (weak,nonatomic) IBOutlet UIVIEw *mainVIEwol;@property (weak,nonatomic) IBOutlet UIbutton *btn1;@property (weak,nonatomic) IBOutlet UIbutton *btn2;@property (weak,nonatomic) IBOutlet UIbutton *btn3;@property (weak,nonatomic) IBOutlet UIbutton *btn4;@property (weak,nonatomic) IBOutlet UIbutton *btn5;@property (weak,nonatomic) IBOutlet UIbutton *btn6;@property (weak,nonatomic) IBOutlet UIbutton *btn7;@property (weak,nonatomic) IBOutlet UIbutton *btn8;@property (weak,nonatomic) IBOutlet UIbutton *btn9;@end@implementation VIEwControllerNSArray* buttons;- (voID)vIEwDIDLoad {    [super vIEwDIDLoad];    buttons = [NSArray arrayWithObjects:_btn1,_btn2,_btn3,_btn4,_btn5,_btn6,_btn7,_btn8,_btn9,nil];    self.mainVIEwol.layer.shadowRadius  = 5;    self.mainVIEwol.layer.shadowcolor   = [UIcolor colorWithRed:211.f/255.f green:211.f/255.f blue:211.f/255.f Alpha:1.f].CGcolor;    self.mainVIEwol.layer.shadowOffset  = CGSizeMake(0.0f,0.0f);    self.mainVIEwol.layer.shadowOpacity = 0.9f;    self.mainVIEwol.layer.masksToBounds = NO;    /* I Have added the 9 button's in an array and used it to reduce the lines of code and for easy understanding as well*/    for (UIbutton* button in buttons) {        button.layer.bordercolor = [UIcolor lightGraycolor].CGcolor;        button.layer.borderWIDth =1.0f;    }}- (IBAction)btnpressed:(UIbutton*)sender {    for (UIbutton* button in buttons) {        [button setSelected:NO];        [button setBackgroundcolor:[UIcolor whitecolor]];        [button setUserInteractionEnabled:true];     // [button setTitlecolor:[UIcolor blackcolor] forState:UIControlStatenormal];        //Based on your needs and colour variant you cant add propertIEs to the button for different control states.        [button setTitlecolor:[UIcolor blackcolor] forState:UIControlStateSelected];    }    NSInteger tag = sender.tag;    sender.selected = ! sender.selected;    if(sender.selected)    {        [sender setSelected:YES];        [sender setUserInteractionEnabled:false];        [sender setBackgroundcolor:[UIcolor purplecolor]];        sender.backgroundcolor = [UIcolor magentacolor];    }}@end

最后的结果

Ignore the delay in button selection,it is caused by the vIDeo to gif conversion.

希望这可以帮助.
