如何自定义可以编辑选中Cell还有简单的动画效果的方式(不用系统原始的编辑方式)

GIF 耐心看完,一般的编辑功能也就这些东西了

编辑cell 目录结构.jpeg实现思路,关键代码
- 首先自定一个cell
自定义cell 这个就不做参数,不明白的可以直接下载demo 看。 - 计算cell 的frame
# addChildView 里面最关键的代码: [self.contentView layoutIfNeeded];一定要有,这个是动画效果实现的关键,有了这句代码,初始的cell 里面空间才会有frame ,这样动画效果才是最逼真的。
- (void)addChildView{
[self.contentView addSubview:self.selectBtn];
[self.selectBtn mas_makeConstraints:^(MASConstraintMaker *make) {
make.leading.mas_equalTo(self.contentView.mas_leading).mas_offset(20);
make.top.mas_equalTo(self.contentView.mas_top).mas_offset(15);
make.size.mas_equalTo(CGSizeMake(20, 20));
}];
[self.contentView addSubview:self.contentLabel];
[self.contentLabel mas_makeConstraints:^(MASConstraintMaker *make) {
make.leading.mas_equalTo(self.selectBtn.mas_trailing).mas_offset(2);
make.top.mas_equalTo(self.contentView.mas_top).mas_offset(15);
make.trailing.mas_equalTo(self.contentView.mas_trailing).mas_offset(-15);
make.bottom.mas_equalTo(self.contentView.mas_bottom).mas_offset(-15);
}];
[self.contentView addSubview:self.bottomLineView];
[self.bottomLineView mas_makeConstraints:^(MASConstraintMaker *make) {
make.leading.mas_equalTo(self.contentView.mas_leading).mas_offset(20);
make.trailing.mas_equalTo(self.contentView.mas_trailing).mas_offset(-20);
make.bottom.mas_equalTo(self.contentView);
make.height.mas_equalTo(0.5);
}];
[self.contentView layoutIfNeeded];
}
- 添加动画效果
# 关键代码看 setModel 方法里面的 对 选中按钮的隐藏,内容的布局,还最简单的addAnimation 动画函数代码
- (void)setModel:(FanEditCellModel *)model{
_model = model;
if (model.isEditStatu) {
self.selectBtn.hidden = NO;
[self.contentLabel mas_remakeConstraints:^(MASConstraintMaker *make) {
make.leading.mas_equalTo(self.selectBtn.mas_trailing).mas_offset(4);
make.top.mas_equalTo(self.contentView.mas_top).mas_offset(15);
make.trailing.mas_equalTo(self.contentView.mas_trailing).mas_offset(-15);
make.bottom.mas_equalTo(self.contentView.mas_bottom).mas_offset(-15);
}];
} else{
self.selectBtn.hidden = YES;
[self.contentLabel mas_remakeConstraints:^(MASConstraintMaker *make) {
make.leading.mas_equalTo(self.contentView.mas_leading).mas_offset(20);
make.top.mas_equalTo(self.contentView.mas_top).mas_offset(15);
make.trailing.mas_equalTo(self.contentView.mas_trailing).mas_offset(-15);
make.bottom.mas_equalTo(self.contentView.mas_bottom).mas_offset(-15);
}];
}
self.selectBtn.selected = model.isSelect;
self.contentLabel.text = model.content;
[self addAnimation];
}
- (void)setIsSelect:(BOOL)isSelect{
_isSelect = isSelect;
self.selectBtn.selected = isSelect;
}
- (void)addAnimation{
[UIView animateWithDuration:0.25 animations:^{
[self.contentView layoutIfNeeded];
}];
}
- 至于选中和删除这个逻辑处理,这个简单不做叙述,给你一个Model
# FanBaseModel 只是一个基础model 你就当做NSObject
@interface FanEditCellModel : FanBaseModel
@property (nonatomic,assign)BOOL isSelect;
@property (nonatomic,strong)NSString *content;
/// YES :表示现在显示管理 NO:表示现在显示完成
@property (nonatomic,assign)BOOL isEditStatu;
@end
