功能点描述
字体SWBaseTextView.h文件
实现了自定义占位文字属性，以及超过字符和长度等。字体的大小，加粗，斜体，对齐方式，间距等属性知识点； 解决UIScorllView和手势冲突，实现了自定义贴纸功能，包括帖子内输入文字，以及贴纸删除，旋转，拉伸等操作；
#pragma mark - 解决手势冲突
- (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event{
//解决移动贴纸，scrollView会滚动
//获取当天触发的View
UIView *view = [super hitTest:point withEvent:event];
BOOL isoldView = [view isEqual:_oldStickerView] ;
//不是贴纸或者表格就打开，是的话就关闭
self.scrollEnabled = !isoldView ;
self.isClickMe = [view isEqual:self];
BOOL is = [view.superview isKindOfClass:[GYStickerView class]] || [view.superview isKindOfClass:[LabView class]];
if (is) {
GYStickerView *sup = (GYStickerView *)view.superview;
if ([sup isKindOfClass:[LabView class]]) {
sup = (GYStickerView *)view.superview.superview;
}
self.scrollEnabled = !sup.isSelected;
}
return view;
}
插入自定义表情作为贴纸
（方法：通过字典来新增一个key值，当操作界面的时候能够获取到当前的贴纸是第几个）
插入自定义图片
（方法：通过字典来新增一个key值，当操作界面的时候能够获取到当前的贴纸是第几个）
///把坐标放进字典
[self.pointDictionary setObject:[NSNumber numberWithFloat:(CGRectGetMaxY(stickerView.frame))] forKey:[NSString stringWithFormat:@"%ld",(long)contentView.tag]];
实现主题功能（从服务端获取主题，再通过缩放系数来切割上中下三张图片）代码如下
CGImageRef imageCenterRef =CGImageCreateWithImageInRect([backGroundimage CGImage], rects);
UIImage *imageCenter = [UIImage imageWithCGImage:imageCenterRef];
每一个操作都必须要调用demo 中的UIScorllView容量ContenSize，代码如下
Demo说明
ViewController这个控制器是主界面，主要承载
/**
滚动主视图
*/
@property(nonatomic , strong)SWMainScorllerView *scrollView;
/**
功能键盘区
*/
@property(nonatomic , strong)SWEditorToolView *keyBoardBox;
我把所有功能逻辑都放在scorllView里面，大部分的控件的逻辑操作都使用通知来监听事件的触发

注意点⚠️
当键盘弹出或消失要做的事情，处理好键盘逻辑坐标
#pragma mark ------键盘以及功能回调--------
-(void)keyboardWillShow:(NSNotification *)info{
NSDictionary *userInfo = [info userInfo];
self.scrollView.contentInset = UIEdgeInsetsMake(0, 0, 0, 0);
UIView * firstResponder = [self.view getCurrenfirstResponder];
CGFloat keyboardH = [userInfo[UIKeyboardFrameEndUserInfoKey] CGRectValue].origin.y;
///隐藏所有的工具栏目
if (self.keyBoardBox) {
[self.keyBoardBox hideAllShowView];
}
if ([firstResponder isKindOfClass:[UIAlertController class]]) {
return;
}
if (firstResponder.tag==100001) {
///键盘弹出,更新坐标，f防止被挡住
[self.scrollView keyBoardShowUpatafram:(keyboardH*.5)+KHeight_Tabar+pointMagin];
return;
}
///键盘弹出,更新坐标，防止被挡住
[self.scrollView keyBoardShowUpatafram:(keyboardH/2)+KHeight_Tabar];
//改变底部键盘工具的Y
CGRect rect = self.keyBoardBox.frame;
rect.origin.y = keyboardH - KHeight_Tabar;
self.keyBoardBox.frame = rect;
CGFloat duration = [userInfo[UIKeyboardAnimationDurationUserInfoKey] doubleValue];
[UIView animateWithDuration:duration animations:^{
[self.view layoutIfNeeded];
}];
}
//当键盘退出时调用
-(void)keyboardWillHiden:(NSNotification *)info{
NSDictionary *userInfo = [info userInfo];
CGRect rect = self.keyBoardBox.frame;
CGFloat keyboardH = [userInfo[UIKeyboardFrameEndUserInfoKey] CGRectValue].origin.y;
rect.origin.y = SCREEN_HEIGHT - KHeight_Tabar -SafeBottomHeight;
self.keyBoardBox.frame = rect;
