我正在制作一个注册警报视图,其中有一个UITextField,用户可以在其中输入注册号.一切都是他们的,但我想以编程方式从文本字段中删除复制粘贴功能,因为他们没有InterfaceBuilder版本的文本字段我不知道如何做到这一点..

这是我到目前为止的UIalertview ......

- (void)pleaseRegisterDevice {

    UIAlertView *myAlertView = [[UIAlertView alloc] initWithTitle:@"Please Register Device!" message:@"this gets covered" delegate:self cancelButtonTitle:nil otherButtonTitles:@"OK", nil];
    regTextField = [[UITextField alloc] initWithFrame:CGRectMake(12.0, 45.0, 260.0, 25.0)];
    [regTextField setBackgroundColor:[UIColor whiteColor]];
    regTextField.textAlignment = UITextAlignmentCenter;
    [myAlertView addSubview:regTextField];
    [myAlertView show];
    [myAlertView release];

}

我想在UITextview上拦截长按,但不想同时禁用上下文菜单选项.

如果我在textview上使用手势识别器,它将禁用上下文菜单,所以我现在使用下面的方法.

- (BOOL)canPerformAction:(SEL)action withSender:(id)sender {    
    //fire my method here
}

但是,它只会在用户长按某些单词后显示上下文菜单时触发该方法.所以当用户长按空格时,只显示放大镜,我当时无法触发方法.

有没有人有更好的想法？谢谢!

感谢@danh和@Beppe,我甚至在UITextView上使用了点击手势.我想通过长按在textview上显示字体栏.

@First,我将UITextview子类化.

@interface LisgoTextView : UITextView {
    BOOL        pressing_;

}

@property (nonatomic)         BOOL      pressing;

@end


@interface LisgoTextView (private)
    - (void)longPress:(UIEvent *)event;
@end


@implementation LisgoTextView

@synthesize pressing = pressing_;


//--------------------------------------------------------------//
#pragma mark -- Long Press Detection --
//--------------------------------------------------------------//

- (void)longPress:(UIEvent *)event {

    if (pressing_) {

        //post notification to show font edit bar
        NSNotification *fontEditBarNotification = [NSNotification notificationWithName:@"fontEditBarNotification" 
                                                                                object:nil userInfo:nil];
        [[NSNotificationCenter defaultCenter] postNotification:fontEditBarNotification];
    }    
}
