iOS13.6.1系統XR手機圖文按鈕顯示不全問題

iOS13.6.1系統XR手機出來了奇怪的問題，圖文按鈕顯示不全問題。比它老的系統或新的系統就是相同的手機都沒有出現類似的問題。就是系統相同手機不同也沒有出現該問題。

既然測試提出該問題，隻能修改了。這是特定手機特定系統适配問題。

修改的思路是：把這個顯示圖檔和文字的按鈕拆分成按鈕包含一個圖檔和一個标簽，計算出他們的文字寬和圖檔寬。若有這樣大量圖文按鈕，若找不到對應頁面，都這樣修改，有可能出現布局不正确的問題。我就是這樣的，産生了好幾個相關的問題，如：計算文字寬度的小數被舍去了和布局的位置不正确。真不知道為了一個手機在特定的系統下出現該問題，進行大批量修改，并産生了一堆問題是否值得。

出問題的代碼：

UIButton *btn  = [UIButton buttonWithTitle:@"  添加車輛" font:SystemFontOfSize(15) color:MainAPPColor];
    [btn setImage:[UIImage imageNamed:@"icon_car_add"] forState:UIControlStateNormal];
    [btn layoutButtonWithEdgeInsetsStyle:  imageTitleSpace:2];

注意：用設定UISemanticContentAttributeForceLeftToRight或标題加空格，采用分類：UIButton+Commemt.h都搞不定這個手機。另一個帶選中效果的問題代碼：

UIButton *btn = [UIButton buttonWithTitle:@" 0" font:SystemFontOfSize(13) color:TextBlackColor];
            [btn setTitleColor:MainAPPColor forState:UIControlStateSelected];
            [btn setImage:[UIImage imageNamed:@"icon_like_no"] forState:UIControlStateNormal];
            [btn setImage:[UIImage imageNamed:@"icon_like_yes"] forState:UIControlStateSelected];
            [btn addTarget:self action:@selector(likeAction:) forControlEvents:UIControlEventTouchUpInside];
            [btn setSemanticContentAttribute:UISemanticContentAttributeForceLeftToRight];
            [btn layoutButtonWithEdgeInsetsStyle:JKButtonEdgeInsetsStyleLeft imageTitleSpace:2];
            [self.contentView addSubview:btn];
            [btn mas_makeConstraints:^(MASConstraintMaker *make) {
                make.left.mas_equalTo(BaseSize(110));
                make.width.mas_equalTo(size.width);
                make.bottom.mas_equalTo(-BaseSize(10));
                make.height.mas_equalTo(BaseSize(24));
            }];
            self.likeBtn = btn;

萬能解決方法是生成一個按鈕子類，上面增加一個圖檔和标簽：

DYTitleImageBtn.h

#import <UIKit/UIKit.h>
//#import "UIButton+Commemt.h"
// 定義一個枚舉（包含了四種類型的button）
typedef NS_ENUM(NSUInteger, JKButtonEdgeInsetsStyle) {
    JKButtonEdgeInsetsStyleTop, // image在上，label在下
    JKButtonEdgeInsetsStyleLeft, // image在左，label在右
    JKButtonEdgeInsetsStyleBottom, // image在下，label在上
    JKButtonEdgeInsetsStyleRight // image在右，label在左
};
