iOS 16 中继续使用 UIPasteboard 来获取获取剪贴板的内容时，会弹出系统提示框，询问用户是否允许粘贴。想去掉弹窗，最好使用 UIPasteControl 控件。
上代码：
-(void)viewDidLoad{
[superviewDidLoad];
if(@available(iOS16.0, *)) {
[_pasteControl removeFromSuperview];
[self.nianqieview removeFromSuperview];
[self getUIPasteControl];
}else{
//获取粘贴板的内容
UIPasteboard*pasteboard = [UIPasteboardgeneralPasteboard];
str = pasteboard.string;
}
}
-(UIPasteControl *)getUIPasteControl API_AVAILABLE(ios(16.0)){
UIPasteControlConfiguration *config = [[UIPasteControlConfiguration alloc]init];
config.baseBackgroundColor = [UIColor greenColor];
config.baseForegroundColor = [UIColor lightGrayColor];
config.cornerStyle = UIButtonConfigurationCornerStyleCapsule;
config.displayMode = UIPasteControlDisplayModeLabelOnly;
_pasteControl = [[UIPasteControl alloc] initWithConfiguration:config];
_pasteControl.frame = CGRectMake(self.view.frame.size.width - 120, self.view.frame.size.height - 160, 70, 40);
UILabel* titleLabel = [[UILabel alloc]init];
titleLabel.frame=CGRectMake(10,10,self.view.frame.size.width-130,60);
titleLabel.numberOfLines=2;
titleLabel.backgroundColor = [UIColor whiteColor];
titleLabel.text=@"是否允许XXXX读取剪切板内容？";
UITextView*policyTextView = [[UITextView alloc]initWithFrame:CGRectMake(10,10,self.view.frame.size.width-130,60)];
policyTextView.delegate=self;
policyTextView.inputView = [[UIView alloc] initWithFrame:CGRectZero];
[policyTextView addSubview:titleLabel];
// 设置target，获取剪切板内容后粘贴的位置
_pasteControl.target= policyTextView;
self.nianqieview= [[UIViewalloc]initWithFrame:CGRectMake(10,self.view.frame.size.height-180,self.view.frame.size.width-20,80)];
self.nianqieview.backgroundColor = [UIColor whiteColor];
[NSTimer scheduledTimerWithTimeInterval:3.0f target:self selector: @selector(performDismiss:)
userInfo:nilrepeats:NO];
[self.nianqieview addSubview:policyTextView];
[self.window addSubview:self.nianqieview];
[self.window addSubview:_pasteControl];
return _pasteControl;
}
- (void)performDismiss: (NSTimer*)timer
{
[_pasteControl removeFromSuperview];
[self.nianqieview removeFromSuperview];
}
- (void)textViewDidChange:(UITextView*)textView{
str = textView.text;
[self.nianqieview removeFromSuperview];
[_pasteControl removeFromSuperview];
}
- (BOOL)textViewShouldBeginEditing:(UITextView *)textView
{
if([textViewisFirstResponder]){
returnYES;
}
return NO;
}
刚开始我把UIPasteControl 放到了我自己画的view上，把textview和label都放在了自己的view上，这时点击UIPasteControl的粘切按钮后，还是会弹出系统的提示框，很是苦恼，后来我把UIPasteControl直接放到页面上面，就不再弹系统的提示框了，我也不知道为什么，如果有跟我出现同样状况的，可以试试把UIPasteControl放到Control上试试。
