一、申明相关属性
@property (nonatomic , strong) MSUShadowView *shadowView;
@property (nonatomic , strong) MSUDatePopView *popView;
二、相关view初始化
- (MSUShadowView *)shadowView{
if (!_shadowView) {
self.shadowView = [[MSUShadowView alloc] initWithFrame:CGRectMake(0, 0, WIDTH, HEIGHT)];
self.shadowView.backgroundColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:0.5];
[self.view addSubview:self.shadowView];
}
return _shadowView;
}
- (MSUDatePopView *)popView{
if (!_popView) {
self.popView = [[MSUDatePopView alloc] initWithFrame:CGRectMake(0, HEIGHT-250, WIDTH, 250)];
[self.shadowView addSubview:_popView];
_popView.backgroundColor = HEXCOLOR(0xfbfbfb);
_popView.delegate = self;
_popView.hidden = YES;
}
return _popView;
}
三、MSUShadowView相关代码
1.MSUShadowView.h 中的代码
#import
@interface MSUShadowView : UIView
@end
2.MSUShadowView.m中的代码
#import "MSUShadowView.h"
@implementation MSUShadowView
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
// self.hidden = YES;
for (UIView *view in self.subviews) {
CGPoint point = [[touches anyObject] locationInView:view];
if (![view.layer containsPoint:point]) {
self.hidden = YES;
view.hidden = YES;
// 支付页面 防止点击view移除键盘
[self endEditing:YES];
}
}
}
@end
四、MSUDatePopView 代码
1.MSUDatePopView.h中的代码
#import
@protocol MSUDatePopViewDelegate
- (void)datePopViewCompleteBtnClickWithStartStr:(NSString *)startStr stopStr:(NSString *)stopStr;
@end
@interface MSUDatePopView : UIView
@property (nonatomic , weak) id delegate;
@property (nonatomic , strong) UIButton *startBtn;
@property (nonatomic , strong) UIButton *stopBtn;
@end
2.MSUDatePopView.m中的代码
#import "MSUDatePopView.h"
#import "MSUHUD.h"

五、点击按钮，显示MSUDatePopView
self.shadowView.hidden = NO;
self.popView.hidden = NO;
六、实现MSUDatePopView代理
- (void)datePopViewCompleteBtnClickWithStartStr:(NSString *)startStr stopStr:(NSString *)stopStr{
self.shadowView.hidden = YES;
self.startStr = startStr;
self.stopStr = stopStr;
self.tableView.mj_header = [MSUDIYHeader headerWithRefreshingTarget:self refreshingAction:@selector(loadNewData2)];
[self.tableView.mj_header beginRefreshing];
}
