iOS 自定义日期和数据源选择控件

需求

App开发中经常会有日期选择（如生日、睡眠定时等）或者省市区选择等此类功能，通常UI中不会单独使用UI中的控件，而是在UIPickerView的基础上增加一个取消和确定按钮

特点

支持常见的选择型的数据格式

该控件集成了 yyyy-MM-dd、yyyy-MM、hh mm、省市级联、省市区级联、自定义数据源（2列）、自定义数据源（3列）等多种格式，

即支持UITextField又支持事件触发机制

即支持XIB也支持纯代码

集成

首先将XXPickerView文件夹拖入到工程中

纯代码（选择任意一种模式）

#import "ViewController.h"
#import "XXTextField.h"

#define random(r, g, b, a) [UIColor colorWithRed:(r)/255.0 green:(g)/255.0 blue:(b)/255.0 alpha:(a)/255.0]
#define RandomColor random(arc4random_uniform(256), arc4random_uniform(256), arc4random_uniform(256), arc4random_uniform(256))

@implementation ViewController

- (void)viewDidLoad {
[super viewDidLoad];

CGFloat x = 170;
CGFloat width = 178;
CGFloat height = 30;
CGFloat margin = 50;

// 模式一
XXTextField *textField = [[XXTextField alloc] init];
textField.frame = CGRectMake(x, 28, width, height);
textField.mode = XXPickerViewModeDate;
textField.backgroundColor = RandomColor;
[self.view addSubview:textField];

// 模式二
XXTextField *textField2 = [[XXTextField alloc] init];
textField2.frame = CGRectMake(x, textField.frame.origin.y + margin, width, height);
textField2.mode = XXPickerViewModeYearAndMonth;
textField2.backgroundColor = RandomColor;
[self.view addSubview:textField2];

// 模式三
XXTextField *textField3 = [[XXTextField alloc] init];
textField3.frame = CGRectMake(x, textField2.frame.origin.y + margin, width, height);
textField3.mode = XXPickerViewModeHourAndMinute;
textField3.backgroundColor = RandomColor;
[self.view addSubview:textField3];

// 模式四
XXTextField *textField4 = [[XXTextField alloc] init];
textField4.frame = CGRectMake(x, textField3.frame.origin.y + margin, width, height);
textField4.mode = XXPickerViewModeProvinceCity;
textField4.backgroundColor = RandomColor;
[self.view addSubview:textField4];

// 模式五
XXTextField *textField5 = [[XXTextField alloc] init];
textField5.frame = CGRectMake(x, textField4.frame.origin.y + margin, width, height);
textField5.mode = XXPickerViewModeProvinceCityAreas;
textField5.backgroundColor = RandomColor;
[self.view addSubview:textField5];

// 模式六
XXTextField *textField6 = [[XXTextField alloc] init];
textField6.frame = CGRectMake(x, textField5.frame.origin.y + margin, width, height);
textField6.mode = XXPickerViewModeDataSourceFor2Column;
textField6.dataSource = [dataSourceFor2Column mutableCopy];
textField6.backgroundColor = RandomColor;
[self.view addSubview:textField6];

// 模式七
XXTextField *textField7 = [[XXTextField alloc] init];
textField7.frame = CGRectMake(x, textField6.frame.origin.y + margin, width, height);;
textField7.mode = XXPickerViewModeDataSourceFor3Column;
textField7.dataSource = [dataSourceFor3Column mutableCopy];
textField7.backgroundColor = RandomColor;
[self.view addSubview:textField7];
}
@end

XIB方式

绑定自定义类


拖线并设置模式

@interface ViewController ()
@property (weak, nonatomic) IBOutlet XXTextField *textField;
@end

@implementation ViewController

- (void)viewDidLoad {
[super viewDidLoad];
_textField.mode = XXPickerViewModeDate;
}

@end

事件方式

#import "ViewController.h"
#import "XXInputView.h"

@interface ViewController ()
@property (weak, nonatomic) XXInputView *inputView;
@end

@implementation ViewController

- (void)viewDidLoad {
[super viewDidLoad];
}

- (IBAction)showClicked:(id)sender {
[self.inputView show];
}

- (XXInputView *)inputView {
if (_inputView == nil) {
XXInputView *inputView = [[XXInputView alloc] initWithFrame:CGRectMake(0, [UIScreen mainScreen].bounds.size.height, [UIScreen mainScreen].bounds.size.width, 200) mode:XXPickerViewModeDate dataSource:nil];
inputView.hideSeparator = YES;
inputView.completeBlock = ^(NSString *dateString){
NSLog(@"selected data : %@", dateString);
};

[self.view addSubview:inputView];

self.inputView = inputView;
}

return _inputView;
}

@end
