倒计时加圆角设置

一、倒计时按钮

1、UIButton+countDown.h设置

/**
 *  倒计时按钮
 *
 *  @param timeLine 倒计时总时间
 *  @param title    还没倒计时的title
 *  @param subTitle 倒计时中的子名字，如时、分
 *  @param color    倒计时中的颜色
 */
- (void)startWithTime:(NSInteger)timeLine title:(NSString *)title countDownTitle:(NSString *)subTitle countColor:(UIColor *)color;

 2、UIButton+countDown.m设置

- (void)startWithTime:(NSInteger)timeLine title:(NSString *)title countDownTitle:(NSString *)subTitle countColor:(UIColor *)color {
    
    //倒计时时间
    __block NSInteger timeOut = timeLine;
    dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0);
    dispatch_source_t _timer = dispatch_source_create(DISPATCH_SOURCE_TYPE_TIMER, 0, 0, queue);
    //每秒执行一次
    dispatch_source_set_timer(_timer, dispatch_walltime(NULL, 0), 1.0 * NSEC_PER_SEC, 0);
    dispatch_source_set_event_handler(_timer, ^{
        
        //倒计时结束，关闭
        if (timeOut <= 0) {
            dispatch_source_cancel(_timer);
            dispatch_async(dispatch_get_main_queue(), ^{
                //self.backgroundColor = mColor;
                [self setTitle:title forState:UIControlStateNormal];
                self.userInteractionEnabled = YES;
            });
        } else {
            int allTime = (int)timeLine + 1;
            int seconds = timeOut % allTime;
            NSString *timeStr = [NSString stringWithFormat:@"%0.2d", seconds];
            dispatch_async(dispatch_get_main_queue(), ^{
                self.backgroundColor = color;
                [self setTitle:[NSString stringWithFormat:@"%@%@",timeStr,subTitle] forState:UIControlStateNormal];
                self.userInteractionEnabled = NO;
            });
            timeOut--;
        }
    });
    dispatch_resume(_timer);
}

 3、SB中设置的倒计时按钮

#import "UIButton+countDown.h"
@interface ViewController ()
@property (strong, nonatomic) IBOutlet UIButton *btn_count;

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    
    [self.btn_count addTarget:self action:@selector(hhh) forControlEvents:UIControlEventTouchDown];
}

- (void)hhh
{
    [self.btn_count  startWithTime:10 title:@"重新获取证码" countDownTitle:@"s" countColor:[UIColor lightGrayColor]];
}
@end

 二、设置圆角

1、UIView+CornerRadius.h的设置

#import <UIKit/UIKit.h>

@interface UIView (CornerRadius)
@property (nonatomic, assign) IBInspectable CGFloat cornerRadius;
@end

 2、UIView+CornerRadius.m的设置

#import "UIView+CornerRadius.h"

@implementation UIView (CornerRadius)

- (void)setCornerRadius:(CGFloat)cornerRadius
{
    self.layer.cornerRadius = cornerRadius;
    self.layer.masksToBounds = cornerRadius > 0;
}

- (CGFloat)cornerRadius
{
    return self.layer.cornerRadius;
}
@end

 3、SB中设置

 

好倒计时圆角按钮完成！
