UITextView cursor below frame when changing frame

对不起,没有截图,因为我(几乎)没有声誉,但它看起来类似于链接的SO帖子.

当我在iOS6上运行应用程序时,工作完美(内容滚动光标以将其保留在屏幕上),但在iOS7上,光标超出了UITextVIEw的末尾.我尝试添加UIEdgeInsets来移动内容,但是当用户主动输入文本时,它只是不断添加新行,直到光标位于文本视图的末尾.

我的布局包含一个Label(headerText),下面有一个UITextVIEw(textVIEw).此视图显示在选项卡栏中.添加了一个键盘输入附件,但在调用该功能之前,它的高度会自动计算到键盘高度.

这是我用来调整视图大小的函数,从键盘显示/隐藏委托,旋转,初始布局等调用：

-(voID)resizeVIEwsWithKbdHeight:(float)kbHeight{    //set the header label frame    //set constraints    //total vIEw wIDth - 30 (15 each for left and right padding)    CGfloat labelWIDth = ([[[self navigationController] vIEw] bounds].size.wIDth - 30);    CGSize constraintSize = {labelWIDth,CGfloat_MAX};    //calculate needed height for header label    CGSize textSize = [[self headerText] sizeWithFont:[UIFont systemFontOfSize:17.0f]                                    constrainedToSize:constraintSize                                        lineBreakMode:NSlineBreakByWorDWrapPing];    //build and set frame for header label:    //make it the same as the old    CGRect headerTempSize = [[self headerLabel] frame];    //except for the height    headerTempSize.size.height = textSize.height;    //and set it    [[self headerLabel] setFrame:headerTempSize];    //correct the placement of the UITextVIEw,so it's under the header label    //build a new frame based on current textvIEw frame    CGRect newFrame = [[self textVIEw] frame];    //get the y position of the uitextvIEw,the +8 is the padding between header and uitextvIEw    CGfloat vertpadding = [[self headerLabel] frame].origin.y + [[self headerLabel] frame].size.height + 8;    //bump it down vertically    newFrame.origin.y = vertpadding;    //bump things down by the amount of the navigation bar and status bar    float offscreenBump = [[[self navigationController] navigationbar] frame].origin.y + [[[self navigationController] navigationbar] frame].size.height;    //if we aren't showing the keyboard,add the height of the tab bar    if(kbHeight == 0) {        offscreenBump += [[[self tabbarController] tabbar] frame].size.height;    }    //calculate the new height of the textvIEw,the +9 is for padding below the text vIEw    CGfloat newHeight = [[[self navigationController] vIEw] bounds].size.height - ([[self textVIEw] frame].origin.y + 9 + kbHeight + offscreenBump);    //resize the height as calculated    newFrame.size.height = newHeight;    //set textvIEw frame to this new frame    [[self textVIEw] setFrame:newFrame];}

我正在尝试支持iOS5,所以没有autoLayout.

我有可能对我的工作方式非常天真.

提前致谢！

解决方法 这似乎是iOS 7中的一个错误.我发现纠正这个问题的唯一方法是为UITextVIEw添加一个委托并实现textVIEwDIDChangeSelection,重置视图以显示如下选择：

#define SYstem_VERSION_GREATER_THAN_OR_EQUAL_TO(v)  ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending)- (voID) textVIEwDIDChangeSelection: (UITextVIEw *) tVIEw {    if (SYstem_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7.0")) {        [tVIEw scrollRangetoVisible:[tVIEw selectedRange]];    }}
