iOS自定义日期和数据源选择控件
需求
在成都网站建设、做网站过程中,需要针对客户的行业特点、产品特性、目标受众和市场情况进行定位分析,以确定网站的风格、色彩、版式、交互等方面的设计方向。创新互联还需要根据客户的需求进行功能模块的开发和设计,包括内容管理、前台展示、用户权限管理、数据统计和安全保护等功能。
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

GitHub:XXPickerView
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
以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持创新互联。
