iphone实现弹出框视图

最近项目中需要写复杂的表单，需要添加日期和多选框内容，所以需要弹出视图添加相关信息。这里写一个原型，用来帮助同事做复杂的表单。

模仿的效果：

实现的效果：

 

实现步骤如下：

创建项目iphone_sprintview创建一个继承UIView的子类SecondView创建一个SecondView.xib。下面打开SecondView.xib，做如下操作：

添加视图：

 

在iphone_sprintviewViewController中添加相应控件的声明。

IBOutlet UIDatePicker *myDataPicker; IBOutlet UIView *myView;

控件关联。

相关的代码：

#import <UIKit/UIKit.h> #import "SecondView.h" @interface iphone_sprintviewViewController : UIViewController {     SecondView *mySecondView;     IBOutlet UIDatePicker *myDataPicker;     IBOutlet UIView *myView; } @property (nonatomic,retain) SecondView *mySecondView; @property (nonatomic,retain) UIDatePicker *myDataPicker; @property (nonatomic,retain) UIView *myView; -(IBAction)onClickButton:(id)sender; @end

 

 

 

#import "iphone_sprintviewViewController.h" #import <QuartzCore/QuartzCore.h> @implementation iphone_sprintviewViewController @synthesize mySecondView,myDataPicker,myView; -(void) viewDidLoad {     self.mySecondView=[[SecondView alloc] init];     NSArray *array =[[NSBundle mainBundle] loadNibNamed:@"SecondView"                                                   owner:self options:nil];     self.mySecondView=[array objectAtIndex:0];     //将图层的边框设置为圆脚     self.myView.layer.cornerRadius = 8;     self.myView.layer.masksToBounds = YES;     //给图层添加一个有色边框     self.myView.layer.borderWidth = 8;     self.myView.layer.borderColor = [[UIColor colorWithRed:0.52 green:0.09 blue:0.07 alpha:0.5] CGColor]; } - (void)didReceiveMemoryWarning {     [super didReceiveMemoryWarning]; } - (void)viewDidUnload {     self.mySecondView=nil;     self.myDataPicker=nil;     self.myView=nil; } - (void)dealloc {     [self.myView release];     [self.mySecondView release];     [self.myDataPicker release];     [super dealloc]; } -(IBAction)onClickButton:(id)sender {     if ([sender tag]==0) {         [self.view addSubview:mySecondView];     }else if ([sender tag]==1) {         [mySecondView removeFromSuperview];     }else {         NSLog(@"==%@",self.myDataPicker.date);         [mySecondView removeFromSuperview];     } } @end
