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

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

效果图

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
