UIDatePicker和UIPickerView的使用
UIDatePicker *datePicker = [ [ UIDatePicker alloc] initWithFrame:CGRectMake(0,0,320,216)];
datePicker.datePickerMode = UIDatePickerModeDateAndTime;
datePicker.locale = [NSLocale localeWithLocaleIdentifier:@"zh_CN"];
[datePicker addTarget:self action:@selector(dateChange:) forControlEvents:UIControlEventValueChanged];
[self.view addSubview:datePicker];
- (void)dateChange:(UIDatePicker *)datePicker
{
NSDate *theDate = datePicker.date;
NSLog(@"%@",[theDate descriptionWithLocale:[NSLocale currentLocale]]);
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
dateFormatter.dateFormat = @"YYYY-MM-dd HH-mm-ss";
NSLog(@"%@",[dateFormatter stringFromDate:theDate]);
}
运行效果：
UIPickerView的使用：
#define currentView_Center CGPointMake([UIScreen mainScreen].bounds.size.width * 1.0 / 2, [UIScreen mainScreen].bounds.size.height * 1.0 / 2)
UIPickerView *pickView = [[UIPickerView alloc] initWithFrame:CGRectMake(0, 0, [UIScreen mainScreen].bounds.size.width, 100)];
pickView.delegate = self;
pickView.dataSource = self;
[pickView setShowsSelectionIndicator:YES];
pickView.center = currentView_Center;
[self.view addSubview:pickView];
self.area = @[@"刘国梁",@"孔令辉"];
self.area = [self.area sortedArrayUsingSelector:@selector(compare:)];
self.dataSourceArr = @[@"王皓",@"马琳",@"王励勤",@"张继科",@"马龙",@"许昕",@"樊振东",@"周雨",@"尚坤",@"波尔"];
self.dataSourceArrM = @[@"丁宁",@"刘诗雯",@"李晓霞",@"陈梦",@"武杨",@"郭跃"];
self.picKViewDic = @{self.area[0]:self.dataSourceArr, self.area[1]:self.dataSourceArrM};
self.selectedArea = self.area[0];
