I use this custom view in vc
SignStepRemindView *stepRemindView = [[SignStepRemindView alloc] init];
[stepRemindView show:self.view];
My question is the UITextField can't edit and touch,the keyboard has never been shown,but when I use [textField becomeFirstResponder],I can input,the keyboard show,but the cursor does not show.
Thank you very much.

Answer 1

I solved it.The reason is that constraints are not complete.
Add the following code at the end of the method addRemindView
[self.remindContentView mas_makeConstraints:^(MASConstraintMaker *make){
make.bottom.equalTo(editView.mas_bottom).offset(20);
}];
