我有一个的UIButton这是一个标志。 这个标志按钮将永远焕发上，但将停止在彤彤是touch.It像一个发光的动画。
有没有什么建议？

我建议你使用的UIView的辉光类别秘密实验室做 。
例如，请点击这里
我喜欢这样的光芒+增长/收缩的动画我的“额外的特殊”按钮：
-(void)makeViewShine:(UIView*) view
{
view.layer.shadowColor = [UIColor yellowColor].CGColor;
view.layer.shadowRadius = 10.0f;
view.layer.shadowOpacity = 1.0f;
view.layer.shadowOffset = CGSizeZero;
[UIView animateWithDuration:0.7f delay:0 options:UIViewAnimationOptionAutoreverse | UIViewAnimationCurveEaseInOut | UIViewAnimationOptionRepeat | UIViewAnimationOptionAllowUserInteraction animations:^{
[UIView setAnimationRepeatCount:15];
view.transform = CGAffineTransformMakeScale(1.2f, 1.2f);
} completion:^(BOOL finished) {
view.layer.shadowRadius = 0.0f;
view.transform = CGAffineTransformMakeScale(1.0f, 1.0f);
}];
}
：发光取自代码创建的UILabel和UIButton的发光效果
首先，你需要导入QuartzCore框架：
#import <QuartzCore/QuartzCore.h>
当你创建一个按钮（或viewDidLoad ，依赖于你的代码结构）添加以下代码：
UIColor *color = button.currentTitleColor;
button.titleLabel.layer.shadowColor = [color CGColor];
button.titleLabel.layer.shadowRadius = 4.0f;
button.titleLabel.layer.shadowOpacity = .9;
button.titleLabel.layer.shadowOffset = CGSizeZero;
button.titleLabel.layer.masksToBounds = NO;
你需要看两个事件： UIControlEventTouchDown和UIControlEventTouchUpInside
在UIControlEventTouchDown处理您将要添加的代码：
UIColor *color = [UIColor clearColor];
button.titleLabel.layer.shadowColor = [color CGColor];
而在UIControlEventUpInside处理您将要添加的代码：
UIColor *color = button.currentTitleColor;
button.titleLabel.layer.shadowColor = [color CGColor];
再次执行的细节取决于你是否创建按钮programmaticaly或通过界面生成器，但我敢肯定，你就可以从这里开始摸不着头脑。
编辑：自定义按钮，只需添加以下代码应工作：
[button setImage:[UIImage imageNamed:@"buttonWithGlow.png"]
forState:UIControlStateNormal];
[button setImage:[UIImage imageNamed:@"buttonWithNoGlow.png"]
forState:UIControlStateHighlighted];

1-创建UIView的扩展与动画
2-使用它在文本框，按钮，次（UIView的任何亚类）
注：U可以更改值和玩得到u需要的效果。
UIView的延伸
import UIKit
extension UIView {
enum GlowEffect: Float {
case small = 0.4, normal = 2, big = 15
}
func doGlowAnimation(withColor color: UIColor, withEffect effect: GlowEffect = .normal) {
layer.masksToBounds = false
layer.shadowColor = color.cgColor
layer.shadowRadius = 0
layer.shadowOpacity = 1
layer.shadowOffset = .zero
let glowAnimation = CABasicAnimation(keyPath: "shadowRadius")
glowAnimation.fromValue = 0
glowAnimation.toValue = effect.rawValue
glowAnimation.beginTime = CACurrentMediaTime()+0.3
glowAnimation.duration = CFTimeInterval(0.3)
glowAnimation.fillMode = kCAFillModeRemoved
glowAnimation.autoreverses = true
glowAnimation.isRemovedOnCompletion = true
layer.add(glowAnimation, forKey: "shadowGlowingAnimation")
}
}
如何使用它：
//TextField with border
textField.doGlowAnimation(withColor: UIColor.red, withEffect: .big)
//Label
label.doGlowAnimation(withColor: label.textColor, withEffect: .small)
//Button
button.doGlowAnimation(withColor: UIColor.red, withEffect: .big)
这里是我的答案....
