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
效果圖
GitHub：XXPickerView
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]; }@endXIB方式
1、綁定自定義類
2、拖線并設置模式
@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以上就是本文的全部內容，希望對大家的學習有所幫助，也希望大家多多支持武林網。
