iOS自定義日期和數據源選擇控件

這篇文章主要爲大家詳細介紹了iOS自定義日期和數據源選擇控件，具有一定的參考價值，感興趣的小夥伴們可以參考一下

需求

App開發中經常會有日期選擇（如生日、睡眠定時等）或者省市區選擇等此類功能，通常UI中不會單獨使用UI中的控件，而是在UIPickerView的基礎上增加一個取消和確定按鈕

特點

1、支持常見的選擇型的數據格式
該控件集成了 yyyy-MM-dd、yyyy-MM、hh mm、省市級聯、省市區級聯、自定義數據源（2列）、自定義數據源（3列）等多種格式

2、即支持UITextField又支持事件觸發機制

3、即支持XIB也支持純代碼

集成

首先將XXPickerView文件夾拖入到工程中

純代碼（選擇任意一種模式）

#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

1、綁定自定義類

2、拖線並設置模式

@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
