IOS开发-显示DatePicker当敲击textfield

最近做项目遇到一个问题，在一个设置页面有两个输入框，想让用户敲击时，弹出日期控件，选择日期时间。Baidu了一遍，发现没有一个完整的解决方案，现在解决了，分享一下。
 
你可以用textfield的inputview和inputAccessoryView两个属性。创建datePicker,赋值给两个textfield的inputview属性。创建易做图，包含一个Done按钮，赋值给inputAccessoryView属性。你需要用这个Done来退出inputview。
 
Done的事件处理：
 
if ( [textField1 isFirstResponder] ) {
    [textField1 resignFirstResponder];
} else if ( [textField2 isFirstResponder] ) {
    [textField2 resignFirstResponder];
}
Example
 
@inte易做图ce CustomKeyboardAppDelegate : NSObject <UIApplicationDelegate> {
...
 
@property (nonatomic, retain) IBOutlet UIWindow *window;
@property (nonatomic, retain) IBOutlet UITextField *textField;
@property (nonatomic, retain) IBOutlet UIToolbar *accessoryView;
@property (nonatomic, retain) IBOutlet UIDatePicker *customInput;
 
- (IBAction)dateChanged:(id)sender;
- (IBAction)doneEditing:(id)sender;
@end
在XIB文件中，拖出 一个UIToolbar和一个UIDatePicker，但不要附加到View中（拖到视图外面）。适当的连接Outlets。dateChanged:响应datepicker的ValueChanges，doneEditing:被ToolBar中的Done按钮点击时调用（Connection->Sent Actions->selectors）。以下是实现：
 
@implementation CustomKeyboardAppDelegate
 
@synthesize window=_window;
@synthesize textField = _textField;
 
@synthesize accessoryView = _accessoryView;
@synthesize customInput = _customInput;
 
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.textField.inputView = self.customInput;
    self.textField.inputAccessoryView = self.accessoryView;
    ...    
}
 
...
 
- (IBAction)dateChanged:(id)sender {
    UIDatePicker *picker = (UIDatePicker *)sender;
 
    self.textField.text = [NSString stringWithFormat:@"%@", picker.date];
}
 
- (IBAction)doneEditing:(id)sender {
    [self.textField resignFirstResponder];
}
@end
