项目介绍：

日期选择器，支持年、年月、年月日、年月日时分、年月日时分秒、时分、时分秒、月日周 时分等

由于使用UIPickerView的话，列表会有个弧度，所以这里用了PGPickerView

Swift使用

Swift教程

CocoaPods安装

pod 'PGDatePicker', '>= 1.3.0'

使用

PGDatePicker *datePicker = [[PGDatePicker alloc]init];
datePicker.delegate = self;
[datePicker show];
datePicker.datePickerMode = PGDatePickerModeYear;
 
#pragma PGDatePickerDelegate
- (void)datePicker:(PGDatePicker *)datePicker didSelectDate:(NSDateComponents *)dateComponents {
    NSLog(@"dateComponents = %@", dateComponents);
}

如果不设置minimumDate和maximumDate默认是无穷小和无穷大

设置Date

建议用NSDate+PGCategory类所定义的方法去设置

+ (NSDate *)setYear:(NSInteger)year;
+ (NSDate *)setYear:(NSInteger)year month:(NSInteger)month;
+ (NSDate *)setYear:(NSInteger)year month:(NSInteger)month day:(NSInteger)day;
+ (NSDate *)setYear:(NSInteger)year month:(NSInteger)month day:(NSInteger)day hour:(NSInteger)hour minute:(NSInteger)minute;
+ (NSDate *)setYear:(NSInteger)year month:(NSInteger)month day:(NSInteger)day hour:(NSInteger)hour minute:(NSInteger)minute second:(NSInteger)second;
+ (NSDate *)setHour:(NSInteger)hour minute:(NSInteger)minute;
+ (NSDate *)setHour:(NSInteger)hour minute:(NSInteger)minute second:(NSInteger)second;
+ (NSDate *)setMonth:(NSInteger)month day:(NSInteger)day hour:(NSInteger)hour minute:(NSInteger)minute;

比如：datePicker.maximumDate = [NSDate setYear:2017];

设置样式

//设置线条的颜色
datePicker.lineBackgroundColor = [UIColor redColor];
//设置选中行的字体颜色
datePicker.titleColorForSelectedRow = [UIColor redColor];
//设置未选中行的字体颜色
datePicker.titleColorForOtherRow = [UIColor blackColor];

//设置取消按钮的字体颜色
datePicker.cancelButtonTextColor = [UIColor blackColor];
//设置取消按钮的字
datePicker.cancelButtonText = @"取消";
//设置取消按钮的字体大小
datePicker.cancelButtonFont = [UIFont boldSystemFontOfSize:17];

//设置确定按钮的字体颜色
datePicker.confirmButtonTextColor = [UIColor redColor];
//设置确定按钮的字
datePicker.confirmButtonText = @"确定";
//设置确定按钮的字体大小
datePicker.confirmButtonFont = [UIFont boldSystemFontOfSize:17];
