详解iOS时间选择框
本文实例为大家介绍了iOS时间选择框的示例代码，供大家参考，具体内容如下
代码：
一、头文件
#import<UIKit/UIKit.h> @classITTPickView; @protocolITTPickViewDelegate<NSObject> @optional -(void)toobarDonBtnHaveClick:(ITTPickView*)pickView resultString:(NSString*)resultString; @end @interfaceITTPickView:UIView @property(nonatomic,weak)id<ITTPickViewDelegate>delegate;//委托 /** *通过时间创建一个DatePicker * *@paramdate默认选中时间 *@paramisHaveNavControler是否在NavControler之内 * *@return带有toolbar的datePicker */ -(instancetype)initDatePickWithDate:(NSDate*)defaulDate datePickerMode:(UIDatePickerMode)datePickerMode isHaveNavControler:(BOOL)isHaveNavControler; /** *从窗口移除本控件 */ -(void)removeView; /** *在窗口显示本控件 */ -(void)showView; @end
二、ITTPickView的实现，主要的控件UIToolBar、UIDatePicker，点击确定后执行-(void)toobarDonBtnHaveClick:(ITTPickView*)
pickViewresultString:(NSString*)resultString（因为是可选的委托事件，实现了才会执行）;获得选择的时间字符串。
#import"ITTPickView.h"
#defineITTToobarHeight40
@interfaceITTPickView()
@property(nonatomic,assign)NSDate*defaulDate;//默认时间
@property(nonatomic,strong)UIDatePicker*datePicker;//datePicker控件
@property(nonatomic,assign)NSIntegerpickeviewHeight;//pickerView的高度
@property(nonatomic,strong)UIToolbar*toolbar;//toolBar控件
@property(nonatomic,copy)NSString*resultString;//返回的时间字符串
@property(nonatomic,assign)NSIntegerselfOriginy;//当前view的frame.origin.y
@property(nonatomic,assign)NSIntegerselfViewInitH;//初始状态view的frame.origin.y
@end
@implementationITTPickView
//初始化ITTPickView，
-(instancetype)initDatePickWithDate:(NSDate*)defaulDatedatePickerMode:(UIDatePickerMode)datePickerModeisHaveNavControler:(BOOL)isHaveNavControler{
self=[superinit];
if(self){
self.defaulDate=defaulDate;
[selfsetUpDatePickerWithdatePickerMode:datePickerMode];
[selfsetFrameWith:isHaveNavControler];
[selfsetUpToolBar];
}
returnself;
}
//设定ITTPickView的frame大小
-(void)setFrameWith:(BOOL)isHaveNavControler{
CGFloattoolViewX=0;
CGFloattoolViewH=self.pickeviewHeight+ITTToobarHeight;
CGFloattoolViewY;
if(isHaveNavControler){
toolViewY=[UIScreenmainScreen].bounds.size.height-toolViewH-50;
}else{
toolViewY=[UIScreenmainScreen].bounds.size.height-toolViewH;
}
CGFloattoolViewW=[UIScreenmainScreen].bounds.size.width;
CGFloattoolViewInitH=[UIScreenmainScreen].bounds.size.height;
self.selfViewInitH=toolViewInitH;//初始状态view的frame.origin.y
self.selfOriginy=toolViewY;//当前view的frame.origin.y
self.frame=CGRectMake(toolViewX,toolViewInitH,toolViewW,toolViewH);
}
//设定datePicker控件的样式以及frame大小，并作为view的子视图
-(void)setUpDatePickerWithdatePickerMode:(UIDatePickerMode)datePickerMode{
UIDatePicker*datePicker=[[UIDatePickeralloc]init];
datePicker.locale=[[NSLocalealloc]initWithLocaleIdentifier:@"zh-CN"];
datePicker.datePickerMode=datePickerMode;
datePicker.backgroundColor=[UIColorwhiteColor];
if(self.defaulDate){
[datePickersetDate:self.defaulDate];
}
self.datePicker=datePicker;
datePicker.frame=CGRectMake(0,ITTToobarHeight,[UIScreenmainScreen].bounds.size.width,datePicker.frame.size.height);
self.pickeviewHeight=datePicker.frame.size.height;
[selfaddSubview:datePicker];
}
//设置toolBar的各个属性，并作为view的子视图
-(void)setUpToolBar{
self.toolbar=[selfsetToolbarStyle];
[selfsetToolbarWithPickViewFrame];
[selfaddSubview:self.toolbar];
}
//设置toolBar的样式
-(UIToolbar*)setToolbarStyle{
UIToolbar*toolbar=[[UIToolbaralloc]init];
UIBarButtonItem*left=[[UIBarButtonItemalloc]initWithTitle:@"取消"style:UIBarButtonItemStylePlaintarget:selfaction:@selector(removeView)];
UIBarButtonItem*centerSpace=[[UIBarButtonItemalloc]initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpacetarget:selfaction:nil];
UIBarButtonItem*right=[[UIBarButtonItemalloc]initWithTitle:@"确定"style:UIBarButtonItemStylePlaintarget:selfaction:@selector(doneClick)];
toolbar.items=@[lefttem,centerSpace,right];
returntoolbar;
}
//设定tooBar的frame大小
-(void)setToolbarWithPickViewFrame{
self.toolbar.frame=CGRectMake(0,0,[UIScreenmainScreen].bounds.size.width,ITTToobarHeight);
}
//点击确定按钮
-(void)doneClick{
if(self.datePicker){
NSDateFormatter*dateFormatter=[[NSDateFormatteralloc]init];
dateFormatter.dateFormat=@"yyyy-MM-dd";
self.resultString=[dateFormatterstringFromDate:self.datePicker.date];
}
if([self.delegaterespondsToSelector:@selector(toobarDonBtnHaveClick:resultString:)]){
[self.delegatetoobarDonBtnHaveClick:selfresultString:self.resultString];
}
[selfremoveView];
}
/**
*从窗口移除本控件
*/
-(void)removeView{
[UIViewanimateWithDuration:0.25fanimations:^{
self.frame=CGRectMake(self.frame.origin.x,self.selfViewInitH,self.frame.size.width,self.frame.size.height);
}completion:^(BOOLfinished){
if(finished){
[selfremoveFromSuperview];
}
}];
}
/**
*在窗口显示本控件
*/
-(void)showView{
[[UIApplicationsharedApplication].keyWindowaddSubview:self];
[UIViewanimateWithDuration:0.25fanimations:^{
self.frame=CGRectMake(self.frame.origin.x,self.selfOriginy,self.frame.size.width,self.frame.size.height);
}completion:^(BOOLfinished){
}];
}
@end
三、运用ITTPickView
UIButton*testBitton=[[UIButtonalloc]initWithFrame:CGRectMake(0,450,111,40)];
[testBittonsetBackgroundColor:[UIColorredColor]];
[testBittonaddTarget:selfaction:@selector(test)forControlEvents:UIControlEventTouchUpInside];
//点击按钮弹出时间选择框
-(void)test{
ITTPickView*datePicker=[[ITTPickViewalloc]initDatePickWithDate:[NSDatedate]datePickerMode:UIDatePickerModeDateisHaveNavControler:NO];
[datePickershowView];
}
