Answer 1

使用与返回键扣除此委托方法辞职textview.see这里

确保u有

urTextView.delegate=self; 

和乌尔viewcontroller.h文件

@interface urViewController : UIViewController<UITextViewDelegate> { 


- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range 
replacementText:(NSString *)text 
{ 
     // Any new character added is passed in as the "text" parameter 
    if ([text isEqualToString:@"\n"]) { 
      // Be sure to test for equality using the "isEqualToString" message 
     [textView resignFirstResponder]; 

      // Return FALSE so that the final '\n' character doesn't get added 
     return NO; 
    } 
     // For any other character return TRUE so that the text gets added to the view 
    return YES;

对于辞职文本视图的键盘你必须处理UITextview的委托方法。

下面是退出UITextview键盘的代码。

- (BOOL)textViewShouldEndEditing:(UITextView *)textView 
{ 
    [textView resignFirstResponder]; 
    return YES; 
} 

-(BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text 
{ 
    if([text isEqualToString:@"\n"]) 
    { 

    } 
    return YES; 
}
