[英]Set UITextView on full screen in ios
I have set a UITextView on full screen of device like in iphone-5s,textView size is (0,44,320,524). 我已经在设备的全屏上设置了UITextView,就像在iPhone-5s中一样,textView的大小为(0,44,320,524)。 when keyboard appear then user cant show the insert text in view.how can I manage the UITextView, can i use UIScrollView for it or any thing else? 当出现键盘时,用户无法在视图中显示插入文本。如何管理UITextView,可以使用UIScrollView还是其他方式?
While editing complete View will move up and after done editing will move down... 编辑完成时,View将向上移动,完成编辑后将向下移动...
(void)textViewDidBeginEditing:(UITextView *)textView {
[self animateTextView: YES];
}
(void)textViewDidEndEditing:(UITextView *)textView {
[self animateTextView:NO];
}
(void) animateTextView:(BOOL) up {
const int movementDistance =heightKeyboard; // tweak as needed
const float movementDuration = 0.3f; // tweak as needed
int movement= movement = (up ? -movementDistance : movementDistance);
NSLog(@"%d",movement);
[UIView beginAnimations: @"anim" context: nil];
[UIView setAnimationBeginsFromCurrentState: YES];
[UIView setAnimationDuration: movementDuration];
self.view.frame = CGRectOffset(self.inputView.frame, 0, movement);
[UIView commitAnimations];
}
I hope it will work for you. 希望它对您有用。
I have solved it by using this code 我已经通过使用此代码解决了
.h file define a value .h文件定义一个值
CGRect originalTextViewFrame;
.m file .m文件
- (void)viewWillAppear:(BOOL)animated
{
// Register notifications for when the keyboard appears
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillHide:) name:UIKeyboardWillHideNotification object:nil];
}
- (void)viewWillDisappear:(BOOL)animated
{
[[NSNotificationCenter defaultCenter] removeObserver:self];
}
- (void)keyboardWillShow:(NSNotification*)notification
{
[self moveTextViewForKeyboard:notification up:YES];
}
- (void)keyboardWillHide:(NSNotification*)notification
{
[self moveTextViewForKeyboard:notification up:NO];
}
- (void)moveTextViewForKeyboard:(NSNotification*)notification up:(BOOL)up
{
NSDictionary *userInfo = [notification userInfo];
NSTimeInterval animationDuration;
UIViewAnimationCurve animationCurve;
CGRect keyboardRect;
[[userInfo objectForKey:UIKeyboardAnimationCurveUserInfoKey] getValue:&animationCurve];
animationDuration = [[userInfo objectForKey:UIKeyboardAnimationDurationUserInfoKey] doubleValue];
keyboardRect = [[userInfo objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue];
keyboardRect = [self.view convertRect:keyboardRect fromView:nil];
[UIView beginAnimations:@"ResizeForKeyboard" context:nil];
[UIView setAnimationDuration:animationDuration];
[UIView setAnimationCurve:animationCurve];
if (up == YES) {
CGFloat keyboardTop = keyboardRect.origin.y;
CGRect newTextViewFrame = textView.frame;
originalTextViewFrame = textView.frame;
newTextViewFrame.size.height = keyboardTop - textView.frame.origin.y - 10;
textView.frame = newTextViewFrame;
}
else
{
// Keyboard is going away (down) - restore original frame
textView.frame = originalTextViewFrame;
}
[UIView commitAnimations];
}
-(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];
//[scrlView setContentOffset:CGPointMake(0,0) animated:YES];
// Return FALSE so that the final '\n' character doesn't get added
return FALSE;
}
// For any other character return TRUE so that the text gets added to the view
return TRUE;
}
use scroll view and then after try 使用滚动视图,然后尝试后
UITextViewDelegate
method 方法
- (void)textViewDidBeginEditing:(UITextView *)textView
{
[scrollView setContentOffset:CGPointMake(0,yourtextview.center.y-200) animated:YES];
}
