iOS16 任何输入控件，在不调试状态双击弹出粘贴框时闪退，什么原因？已崩溃：com.apple.main-thread EXC_BAD_ACCESS KERN_INVALID_ADDRESS 0x0000000000000020

同行，你好，我估计也遇到类似的问题了，经排查：是一个UITextField的分类导致的，代码如下：必现：

#import "UITextField+Select.h"

@implementation UITextField (Select)

(NSRange)selectedRange

{

UITextPosition *beginning = self.beginningOfDocument;

UITextRange *selectedRange = self.selectedTextRange;

UITextPosition *selectionStart = selectedRange.start;

UITextPosition *selectionEnd = selectedRange.end;

NSInteger location = [self offsetFromPosition:beginning toPosition:selectionStart];

NSInteger length = [self offsetFromPosition:selectionStart toPosition:selectionEnd];

return NSMakeRange(location, length);

}

(void)selectedText

{

UITextRange *range = [self textRangeFromPosition:self.beginningOfDocument toPosition:self.endOfDocument];

[self setSelectedTextRange:range];

}

(void)setSelectedRange:(NSRange)range

{

UITextPosition *beginning = self.beginningOfDocument;

UITextPosition *startPosition = [self positionFromPosition:beginning offset:range.location];

UITextPosition *endPosition = [self positionFromPosition:beginning offset:NSMaxRange(range)];

UITextRange *selectionRange = [self textRangeFromPosition:startPosition toPosition:endPosition];

[self setSelectedTextRange:selectionRange];

}

@end

iOS16以后的机型（真机或者模拟器）都会，我也搞不懂啥情况，debug模式就是定位不到，[捂脸]才一个个第三方文件排查，新建的demo，uitextfield的输入框，没问题，加了那个文件，即使没用，加入项目也会导致，关闭项目，运行iOS16的设备，双击输入框，基本就会crash。
