UIDatePicker as inputView
UIDatePicker as inputView
提问于 2014-04-17 12:08:00
我在UIDatePicker作为inputView有两个问题。
1:当我在datePicker中选择“4月17日晚上9点”时，
dateTextField输出"2014-04-107 21:00:00“。
2:我的国家 UTC是+0900。
但是，NSLog输出"2014-04-17 12:00:00 +0000“。
我该如何解决这些问题？
@property IBOutlet UITextField* dateTextField;
@property IBOutlet UIDatePicker* datePicker;
@property UIToolbar* toolBar;
- (void)viewDidLoad
{
self.datePicker = [[UIDatePicker alloc]initWithFrame:CGRectMake(0, 600, 320, 216)];
[self.view addSubview:self.datePicker];
self.toolBar = [[UIToolbar alloc]initWithFrame:CGRectMake(0, -40, 320, 40)];
self.toolBar.barStyle = UIBarStyleBlackOpaque;
UIBarButtonItem* doneButton = [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(dateTextFieldShouldReturn)];
NSArray* finishBarItems = [NSArray arrayWithObjects:doneButton, nil];
[self.toolBar setItems:finishBarItems animated:YES];
self.dateTextField = [[UITextField alloc]initWithFrame:CGRectMake(40, 293, 250, 30)];
self.dateTextField.delegate = self;
self.dateTextField.inputView = self.datePicker;
self.dateTextField.inputAccessoryView = self.toolBar;
[myScrollView addSubview:self.dateTextField];
}
- (void)dateTextFieldShouldReturn
{
NSDateFormatter* formatter = [[NSDateFormatter alloc]init];
[formatter setDateFormat:@"yyyy-MM-DD HH:mm:ss"];
NSString* dateString = [formatter stringFromDate:self.datePicker.date];
[self.dateTextField setText:dateString];
[self.dateTextField resignFirstResponder];
NSDate* date = [formatter dateFromString:self.dateTextField.text];
NSLog(@"%@", date);

就像这个对我有用：
- (void)dateTextFieldShouldReturn
{
NSDateFormatter* formatter = [[NSDateFormatter alloc]init];
[formatter setLocale:[[NSLocale alloc] initWithLocaleIdentifier:@"en_GB"]];
[formatter setDateFormat:@"EEE, dd MMM yyyy HH:mm:ss zzz"];
NSString* dateString = [formatter stringFromDate:self.datePicker.date];
[self.dateTextField setText:dateString];
[self.dateTextField resignFirstResponder];
NSDate* date = [formatter dateFromString:self.dateTextField.text];
NSLog(@"%@", date);
