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

1、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

2、即支持UITextField又支持事件触发机制

3、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

1、绑定自定义类

2、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
