i 在我的申请中,要限制特定UITextfield的复印件或陈规陋习。
在载有
-(BOOL)canPerformAction:(SEL)action withSender:(id)sender
{
UIMenuController *menuController = [UIMenuController sharedMenuController];
if (menuController) {
[UIMenuController sharedMenuController].menuVisible = NO;
}
return NO;
}
页: 1
- (BOOL)canPerformAction:(SEL)action withSender:(id)sender
{
if (action == @selector(paste:) // or @selector(copy:)
return NO;
return [super canPerformAction:action withSender:sender];
}
• 建立UIText外地分级。
该次
- (BOOL)canPerformAction:(SEL)action withSender:(id)sender { if (sel_isEqual(action, @selector(copy:))) //@selector(paste:) { return NO; } return [super canPerformAction:action withSender:sender]; }
然后,将这一子级用于你不希望能够复制和使用常规的UIText的现场。 你可以复制的领域。

You can implement it like this:
-(BOOL)canPerformAction:(SEL)action withSender:(id)sender
{
if (action == @selector(paste:)) {
return NO;
}
return [super canPerformAction:action withSender:sender];
}
否则,你可以写:
- (BOOL)canBecomeFirstResponder {
return NO;
}
