iOS13.6.1系统XR手机出来了奇怪的问题，图文按钮显示不全问题。比它老的系统或新的系统就是相同的手机都没有出现类似的问题。就是系统相同手机不同也没有出现该问题。
既然测试提出该问题，只能修改了。这是特定手机特定系统适配问题。
修改的思路是：把这个显示图片和文字的按钮拆分成按钮包含一个图片和一个标签，计算出他们的文字宽和图片宽。若有这样大量图文按钮，若找不到对应页面，都这样修改，有可能出现布局不正确的问题。我就是这样的，产生了好几个相关的问题，如：计算文字宽度的小数被舍去了和布局的位置不正确。真不知道为了一个手机在特定的系统下出现该问题，进行大批量修改，并产生了一堆问题是否值得。
出问题的代码：
UIButton *btn = [UIButton buttonWithTitle:@" 添加车辆" font:SystemFontOfSize(15) color:MainAPPColor]; [btn setImage:[UIImage imageNamed:@"icon_car_add"] forState:UIControlStateNormal]; [btn layoutButtonWithEdgeInsetsStyle: imageTitleSpace:2];
注意：用设置UISemanticContentAttributeForceLeftToRight或标题加空格，采用分类：UIButton+Commemt.h都搞不定这个手机。另一个带选中效果的问题代码：
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;
万能解决方法是生成一个按钮子类，上面增加一个图片和标签：
DYTitleImageBtn.h

使用的代码：
CGSize size = [DYTitleImageBtn getSizeWithMaxTitle:@"9999" maxImage:[UIImage imageNamed:@"icon_like_no"] font:SystemFontOfSize(13) imageTitleSpace:5 heigth:BaseSize(24)]; DYTitleImageBtn *btn = [DYTitleImageBtn btnWithFrame:CGRectMake(0, 0, size.width, size.height) title:@"0" selectedTitle:@"0" image:[UIImage imageNamed:@"icon_like_no"] selectedImage:[UIImage imageNamed:@"icon_like_yes"] font:SystemFontOfSize(13) color:TextBlackColor selectedTitleColor:MainAPPColor style:JKButtonEdgeInsetsStyleLeft imageTitleSpace:5.0]; [btn addTarget:self action:@selector(likeAction:) forControlEvents:UIControlEventTouchUpInside]; [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;
更新数据：
- (void)likeAction:(DYTitleImageBtn *)sender{ DYWeakSelf; [NetWorkManager postWithPath:Url_Course_Favor param:@{@"CourseId":@(self.model.CourseId)} dataClass:[TSCourseModel class] isArray:NO].complete = ^(DYNetModel *net, TSCourseModel * data) { if (net.code == DYNetModelStateSuccess) { weakSelf.model.FavorCount = data.FavorCount; [sender setSelected:YES]; weakSelf.likeBtn.userInteractionEnabled = NO; // [sender setTitle:[NSString stringWithFormat:@" %ld",(long)data.FavorCount] forState:UIControlStateNormal]; // weakSelf.likeBtn.jk_titleLab.text = [NSString stringWithFormat:@"%ld",(long)data.FavorCount]; CGSize size = [DYTitleImageBtn getSizeWithMaxTitle:[NSString stringWithFormat:@" %ld",(long)data.FavorCount] maxImage:[UIImage imageNamed:@"icon_like_no"] font:SystemFontOfSize(13) imageTitleSpace:5 heigth:BaseSize(24)]; [weakSelf.likeBtn updateLayoutWithFrame:CGRectMake(0, 0, size.width, size.height) title:[NSString stringWithFormat:@" %ld",(long)data.FavorCount]]; [weakSelf.likeBtn mas_remakeConstraints:^(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)); }]; weakSelf.likeBtn.isSelectContent = YES; } }; }
一个测试用他的手机iPhone xr ios 13.6.1测试出来该问题：结果找到iOS13.6.1 iPhone 6手机和iOS 15 iPhone xr手机都测试正常。老板非要修改没有办法，只能把图文按钮拆分为按钮，图文和标签三个控件才能解决。苹果的手机屏幕不是完全相等的，可能他那个手机比标准尺寸小一点点，我见一个同事的手机屏幕高比标准标屏幕多一点点（他的屏幕高度是比标准屏幕高高0.000002）。所以有的问题是特别手机问题，可以不修改，没有必要兼容百分之百的手机，若领导一定要修改，只能用笨方法修改了。
