iOS通过pickerView自定义简单的时间选择器

/** 初始化pickerView */
-(void)initPickerView

// toolBarView.backgroundColor = [UIColor orangeColor];
[self addSubview:toolBarView];

NSArray *btnTitleArr = [NSArray arrayWithObjects:@"取消",@"确定", nil];

for(int i=0; i < [btnTitleArr count]; i++)
{
UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
btn.frame = CGRectMake(i*toolBarView.frame.size.width/2,0, toolBarView.frame.size.width/2, toolBarView.frame.size.height);

[toolBarView addSubview:lineView];
}
}

//设置默认选择当前时间
[self.hourPickerView selectRow:currentHour inComponent:0 animated:YES];

}

/** 初始化数据源 */
-(void)_setArr
{

使用方法:

//通过block响应调用事件和接受选择的时间值
__weak CustomDatePickView *wDatePickerView = datepickView;
datepickView.hidePickerView = ^(NSInteger senderTag,NSString *selectTime){
switch (senderTag) {
case 100:
{
[wDatePickerView removeFromSuperview];
}
break;
case 101:
{
[wDatePickerView removeFromSuperview];
selectTimeStr = selectTime;
NSString *selectDate = @"";
for(UIButton *btn in self.storedBtnView.subviews)
{
if(btn.selected)
{
switch (btn.tag) {
case 100://今天
{
selectDate = [NSString stringWithFormat:@"%d-%02d-%02d %@ %@",[dateDic[@"year"] intValue],[dateDic[@"month"] intValue],[dateDic[@"day"] intValue],[self _getWeakDay:btn],selectTime];

[self updateBookingBtnUI:selectDate];
}
break;
case 101://明天
{
selectDate = [NSString stringWithFormat:@"%d-%02d-%02d %@ %@",[dateDic[@"nextYear"] intValue],[dateDic[@"tomorrowMonth"] intValue],[dateDic[@"tomorrow"] intValue],[self _getWeakDay:btn],selectTime];
[self updateBookingBtnUI:selectDate];
}
break;
case 102://后天
{
selectDate = [NSString stringWithFormat:@"%d-%02d-%02d %@ %@",[dateDic[@"lastYear"] intValue],[dateDic[@"afterDayMonth"] intValue],[dateDic[@"afterDay"] intValue],[self _getWeakDay:btn],selectTime];
[self updateBookingBtnUI:selectDate];
}
break;
default:
break;
}
}
}
}
break;
default:
break;
}
};
[self.view addSubview:datepickView];
