1. Menu的初始化设置
- (void)showMenuAtRect:(CGRect)rect inView:(UIView *)inView
{
[self becomeFirstResponder];
UIMenuController *theMenu = [UIMenuController sharedMenuController];
[theMenu setMenuVisible:NO animated:YES];
UIMenuItem *copyItem = [[[UIMenuItem alloc] initWithTitle:@"复制" action:@selector(copyAction:)] autorelease];
[theMenu setMenuItems:[NSArray arrayWithObjects:copyItem,nil]];
[theMenu setTargetRect:rect inView:inView];
[theMenu setMenuVisible:YES animated:YES];
}
需要注意的是
[self becomeFirstResponder];
一定不能少了
2. Menu的事件响应及显示下面两个方法不能少了,返回Yes
-(BOOL)canPerformAction:(SEL)action withSender:(id)sender{
if (action == @selector(copyAction:)) {
return YES;
}
return NO;
}
-(BOOL)canBecomeFirstResponder{ // 默认是NO
return YES;
}
