Question

以下是 portrait 文本字段移动的一些很棒的教程。

另一方面，

我的视图旋转为纵向和横向，并且在两个方向上键盘都遮挡了文本字段......现在，纵向和一个的横向方向都可以工作。

所以我想知道如何将两种景观方向都包括在内。

这就是我正在做的事情：

-(void) keyboardWillShow:(NSNotification *)notif{
 if ([serverIP isFirstResponder]){
    if (isPortrait && self.view.frame.origin.y >= 0){
        [self setViewMovedVertical:YES];
    }
    else if (!isPortrait && self.view.frame.origin.x >= 0){
        [self setViewMovedHorizontal:YES];
    }
 }
}

移动视图。以下是相应的方法

#define PORTRAIT_KEY_OFF 216
#define LANDSCAPE_KEY_OFF 140

-(void) setViewMovedVertical:(BOOL)movedUp{
 [UIView beginAnimations:nil context:NULL];
 [UIView setAnimationDuration:0.4];

 CGRect rect = self.view.frame;

 if (movedUp){
     rect.origin.y -= PORTRAIT_KEY_OFF;
     rect.size.height += PORTRAIT_KEY_OFF;
 }
 else{
     rect.origin.y += PORTRAIT_KEY_OFF;
     rect.size.height -= PORTRAIT_KEY_OFF;
 }

 self.view.frame = rect;

 [UIView commitAnimations];
}

-(void) setViewMovedHorizontal:(BOOL)moved{
 [UIView beginAnimations:nil context:NULL];
 [UIView setAnimationDuration:0.4]; 

 CGRect rect = self.view.frame;

 if (moved){
     rect.origin.x -= LANDSCAPE_KEY_OFF;
     rect.size.width += LANDSCAPE_KEY_OFF;
 }
 else{
     rect.origin.x += LANDSCAPE_KEY_OFF;
     rect.size.width -= LANDSCAPE_KEY_OFF;
 }

 self.view.frame = rect;

 [UIView commitAnimations];

}

以下是将其移回的方法

-(IBAction) serverIPDone: (UITextField *) sender{
if ([serverIP isFirstResponder]){
 if (self.view.frame.origin.y < 0){
    [self setViewMovedVertical:NO];
 }
 if (self.view.frame.origin.x < 0){
    [self setViewMovedHorizontal:NO];   
 }
 [serverIP resignFirstResponder];
}
}

希望你能帮忙！如果我反消歧（看我在那里做了什么？）这个问题，请告诉我！

Answer 1

最终想出来!!!!

这是错误的：原点在两种景观模式之间确实发生了变化。所以你要做的就是检测你所处的景观版本，并根据它添加或减去！

-(IBAction) serverIPDone: (UITextField *) sender{
if ([serverIP isFirstResponder]){
        if (self.view.frame.origin.y < 0){
            [self setViewMovedVertical:NO];
        }
    if (self.view.frame.origin.x != 0){
        [self setViewMovedHorizontal:NO];   
    }
    [serverIP resignFirstResponder];
}
}

上一个确保键盘未设置。

-(void) setViewMovedVertical:(BOOL)movedUp{
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.4];

CGRect rect = self.view.frame;

if (movedUp){
    rect.origin.y -= PORTRAIT_KEY_OFF;
    rect.size.height += PORTRAIT_KEY_OFF;
}
else{
    rect.origin.y += PORTRAIT_KEY_OFF;
    rect.size.height -= PORTRAIT_KEY_OFF;
}

self.view.frame = rect;

[UIView commitAnimations];
}

-(void) setViewMovedHorizontal:(BOOL)moved{
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.4]; 

CGRect rect = self.view.frame;

if (moved){
    if (leftLandscape)
        rect.origin.x -= LANDSCAPE_KEY_OFF;
    else
        rect.origin.x += LANDSCAPE_KEY_OFF;
}
else{
    if (leftLandscape)
        rect.origin.x += LANDSCAPE_KEY_OFF;
    else
        rect.origin.x -= LANDSCAPE_KEY_OFF;
    NSLog(@"after: %f",rect.origin.x);

}

self.view.frame = rect;

[UIView commitAnimations];

}

上一页将执行键盘的实际移动。我摆脱了调整大小，你可以把它重新加入。

- (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)x     
                                     duration:(NSTimeInterval)duration{

if (UIInterfaceOrientationIsPortrait(x)) {
    isPortrait = TRUE;  
} 
else { 
    isPortrait = FALSE;
            leftLandscape = (x == UIInterfaceOrientationLandscapeLeft); 
}

}

上一页会确保您正确设置变量isPortrait和leftLandscape。

花了太长时间，但我终于 DONE !!!
