一、可翻页的卡片式弹出框的实现
1.首先我们需要自定义绘制一个取消按钮
========
- 新建一个类
QKInfoCardCloseButton继承自UIButton
========
- 添加属性
@property (nonatomic) UIColor *buttonStrokeColor;
=======
- 实现方法
-(instancetype)initWithFrame:(CGRect)frame;-(id)initWithCoder:(NSCoder *)aDecoder-(instancetype)init
-(instancetype)initWithFrame:(CGRect)frame {
self = [super initWithFrame:frame];
if (self) {
[self setUp];
}
return self;
}
-(id)initWithCoder:(NSCoder *)aDecoder {
self = [super initWithCoder:aDecoder];
if (self) {
[self setUp];
}
return self;
}
-(instancetype)init {
return [self initWithFrame:CGRectZero];
}
=======
- 设置背景色
backgroundColor设置self.showsTouchWhenHighlighted = YES;
- (void)setUp {
self.backgroundColor = [UIColor whiteColor];
self.showsTouchWhenHighlighted = YES;
}
=======
- 重写
- (void)drawRect:(CGRect)rect来绘制按钮
2.新建一个类QKInfoCardContainerView继承自UIView用来实现显示区域
- 添加以下属性
=====
@property (assign, nonatomic) CGFloat cornerRadius;//显示区域的圆角
@property (strong, nonatomic) UIColor *containerBackgroundColor;//显示区域的背景色
@property (strong, nonatomic) UIColor *closeButtonTintColor;//关闭按钮的线条颜色
@property (strong, nonatomic) UIColor *closeButtonBackgroundColor;//关闭按钮的背景色
@property (strong, nonatomic) NSArray *containtViews;//用来展示的子控制器
- 添加私有属性
@implementation QKInfoCardContainerView {
QKInfoCardCloseButton *_closeButton;//关闭按钮
UIView *_containerView;//展示视图
UIScrollView *_scrollView;
}
- 同样去实现三个构造方法
===
-(instancetype)initWithFrame:(CGRect)frame {
self = [super initWithFrame:frame];
if (self) {
[self setUp];
}
return self;
}
-(id)initWithCoder:(NSCoder *)aDecoder {
self = [super initWithCoder:aDecoder];
if (self) {
[self setUp];
}
return self;
}
-(instancetype)init {
return [self initWithFrame:CGRectZero];
}
