集成讯飞输入法的问题

UITextview

1, 在光标位置插入输入的文本

 NSUInteger location = self.selectedRange.location;

2, 对textView赋值以后默认滚动到最后 滚动到光标位置代码为

 // 调整光标
    self.selectedRange = NSMakeRange(location + result.length, 0);
// 滚动到光标位置
    [self scrollRangeToVisible:self.selectedRange];

// 这个属性暂时记录, 没有用到 网上说有用 但是需要在viewdidappear
//    self.textView.layoutManager.allowsNonContiguousLayout = NO;

总的代码为

-(void)voiceKeyboardDidRecognitionResult:(NSString *)result {

    
    // 获得光标所在的位置
    NSUInteger location = self.selectedRange.location;
    // 将UITextView中的内容进行调整（主要是在光标所在的位置进行字符串截取，再拼接你需要插入的文字即可）
    NSString *content = self.text;
    NSString *tempContent = [NSString stringWithFormat:@"%@%@%@",[content substringToIndex:location],result,[content substringFromIndex:location]];
    // 将调整后的字符串添加到UITextView上面
    self.text = tempContent;
    
    GFVoiceToolBar *toolbar = (GFVoiceToolBar *)self.inputAccessoryView;
    [toolbar setLabelText:[NSString stringWithFormat:@"已经输入 %zd 字", self.text.length]];
    
    // 调整光标
    self.selectedRange = NSMakeRange(location + result.length, 0);
    
    // 滚动到光标位置
    [self scrollRangeToVisible:self.selectedRange];

}

UITextField

1, UITextField没有selectedRange属性
所以创建分类 让他拥有

UITextField+TKExtentRange.h

#import <UIKit/UIKit.h>

@interface UITextField (TKExtentRange)


- (NSRange) selectedRange;
- (void) setSelectedRange:(NSRange) range;


@end

UITextField+TKExtentRange.m

#import "UITextField+TKExtentRange.h"

@implementation UITextField (TKExtentRange)

- (NSRange) selectedRange
{
    UITextPosition* beginning = self.beginningOfDocument;
    
    UITextRange* selectedRange = self.selectedTextRange;
    UITextPosition* selectionStart = selectedRange.start;
    UITextPosition* selectionEnd = selectedRange.end;
    
    const NSInteger location = [self offsetFromPosition:beginning toPosition:selectionStart];
    const NSInteger length = [self offsetFromPosition:selectionStart toPosition:selectionEnd];
    
    return NSMakeRange(location, length);
}

- (void) setSelectedRange:(NSRange) range  // 备注：UITextField必须为第一响应者才有效
{
    UITextPosition* beginning = self.beginningOfDocument;
    
    UITextPosition* startPosition = [self positionFromPosition:beginning offset:range.location];
    UITextPosition* endPosition = [self positionFromPosition:beginning offset:range.location + range.length];
    UITextRange* selectionRange = [self textRangeFromPosition:startPosition toPosition:endPosition];
    
    [self setSelectedTextRange:selectionRange];
}
@end

这样UITextField的光标使用方式就和UITextview相同了
