当我在alertview上添加textview时，将TextView添加到UIAlertView

Question

scollview显示在文本的顶部和后面绘制文本如何克服此问题。下面是代码

问题更新：

如果设定textView.editable = NO;它工作正常，但在我的情况下，我需要在textview中键入文本。

UITextView *textView = [[UITextView alloc]initWithFrame:CGRectMake(12, 50, 260, 50)]; 

    [textView setText:@"lashdasjh asdasjdas asdlajsdl adsjajadsd aslj daj sdjasdjasjdlasjd as dlasj d"]; 

    UIAlertView *av = [[UIAlertView alloc]initWithTitle:@"Type Your Message" message:@"\n\n\n\n\n\n" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Send",nil]; 

    av.alertViewStyle = UIAlertViewStyleDefault; 

    [av addSubview:textView]; 

    [av show]; 

Answer 1

解决自己。在消息删除@"\n\n\n\n\n\n"和标题

Answer 2

添加@"\n\n\n\n\n\n"与此代码的工作精细取代你的代码。

UITextView *textView = [[UITextView alloc]initWithFrame:CGRectMake(12, 50, 260, 100)]; 

UIAlertView *av = [[UIAlertView alloc]initWithTitle:@"Type Your Message" message:@"\n\n\n\n\n" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Send",nil]; 

av.alertViewStyle = UIAlertViewStyleDefault; 

[av addSubview:textView]; 

[av show];

这不会对IOS7工作了，但使用https://github.com/wimagguc/ios-custom-alertview会帮你把它做得很好
