UITextField键盘不能input任何内容

加载一个xib文件作为一个UIView，我得到了一个UITextFieldforms的Xib文件（它只是一个包含文本框和button的视图）。 但是，当应用程序启动，文本框出现。 我无法在此UITextField上input任何字母。 但粘贴一个文本到该UITextField是好的。 为什么？ 这是我的添加代码

-(IBAction)showSheet{ UIView *myView = [[[NSBundle mainBundle] loadNibNamed:@"LoginViewComp" owner:self options:NULL] lastObject]; [myView setFrame:CGRectMake(0, 44, 320, 400)]; UIButton *btn1 = (UIButton *)[myView viewWithTag:101]; UITextField *field = (UITextField *)[myView viewWithTag:102]; UILabel *lbl = (UILabel *)[myView viewWithTag:103]; [field setEnabled:YES]; [btn1 addTarget:self action:@selector(testBtn1) forControlEvents:UIControlEventTouchUpInside]; DTActionSheet *sheet = [[DTActionSheet alloc] initWithContentView:myView sheetTitle:@"Demo"]; [sheet showInView:self.view]; [sheet setUserInteractionEnabled:YES]; } -(void)testBtn1{ NSLog(@"btn1 touch up inside"); } @end 

DTActionSheet.m

 @interface DTActionSheet() @property (nonatomic,strong) UIView* contentView; @property (nonatomic,strong) UIToolbar* toolBar; @end @implementation DTActionSheet @synthesize contentView=_contentView; @synthesize toolBar=_toolBar; -(id)initWithContentView:(UIView*)contentView sheetTitle:(NSString*)title; { self = [super init]; if (self) { _contentView = contentView; int btnnum = (contentView.frame.size.height-5)/50; // (height+44-20-25)/50 for(int i=0; i<btnnum; i++) { [self addButtonWithTitle:@" "]; } _toolBar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)]; _toolBar.barStyle = UIBarStyleBlackOpaque; UIBarButtonItem *titleButton = [[UIBarButtonItem alloc] initWithTitle:title style:UIBarButtonItemStylePlain target:nil action:nil]; UIBarButtonItem *rightButton = [[UIBarButtonItem alloc] initWithTitle:@"Done" style:UIBarButtonItemStyleDone target:self action:@selector(done)]; UIBarButtonItem *leftButton = [[UIBarButtonItem alloc] initWithTitle:@"Cancel" style:UIBarButtonItemStyleBordered target:self action:@selector(cancel)]; UIBarButtonItem *fixedButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil]; [_toolBar setItems: [NSArray arrayWithObjects:leftButton,fixedButton,titleButton,fixedButton,rightButton,nil]]; [self addSubview:_toolBar]; [self addSubview:_contentView]; } return self; } -(void)done { [self dismissWithClickedButtonIndex:0 animated:YES]; } -(void)cancel { [self dismissWithClickedButtonIndex:0 animated:YES]; } @end 

嘿，伙计们，有什么想法？

尝试使用UIKeyInput协议参考input – http://developer.apple.com/library/ios/#DOCUMENTATION/UIKit/Reference/UIKeyInput_Protocol/Reference/Reference.html

确保使用它的委托..
