UITableViewCell edit mode Customize the Picture button on the left

First, let's take a look at an effect chart that we're going to do today:

We want to implement the edit mode, the cell moves to the right, showing the delete button.
Looking for a long time on the internet, did not find a solution, the Internet is to modify the image of multiple selection mode, the theory is nothing more than to facilitate the bottom cell, to find more than the selected ImageView and then replace the picture. To achieve this effect, the simplest thing is to find ImageView in the Add mode. But the reality tells me, is impossible. So you just have to define it yourself.

First, we implement the click into edit mode inside the TableView:

-(void) viewdidload {[Super viewdidload];

    Self.view.backgroundcolor=jycolor (240, 239, 249, 1);

    self.navigationitem.title=@ "timing Switch"; Self.navigationitem.rightbarbuttonitem=[[uibarbuttonitem alloc]initwithtitle:@ "edit" style:
    Uibarbuttonitemstyledone target:self Action: @selector (Rightbarbtnclick:)];

[Self setupsubviews]; }-(void) Rightbarbtnclick: (Uibarbuttonitem *) btn {if ([Btn.title isequaltostring:@ edit]) {}else{} SE
    lf.tableview.editing=!self.tableview.editing;
Btn.title=[btn.title isequaltostring:@ "edit"]?@ "Cancel": @ "edit";
    }-(void) setupsubviews {uitableview *tableview=[[uitableview alloc]init];
    Tableview.backgroundcolor=jycolor (240, 239, 249, 1);
    Self.tableview=tableview;
    [Self.tableview Settablefooterview:[[uiview Alloc]initwithframe:cgrectzero]];
    [Self.view Addsubview:tableview];
    tableview.delegate=self;
    tableview.datasource=self;
    Tableview.translatesautoresizingmaskintoconstraints=no; [TableView AutopineDgetosuperviewedge:aledgeleading];
    [TableView autopinedgetosuperviewedge:aledgetrailing];
    [TableView Autopinedgetosuperviewedge:aledgetop];

[TableView Autopinedgetosuperviewedge:aledgebottom withinset:115];

    self.tableview.allowsMultipleSelectionDuringEditing = YES;
    UIButton *addbtn=[[uibutton Alloc]init];
    Addbtn.backgroundcolor=[uicolor Bluecolor];
    [Self.view ADDSUBVIEW:ADDBTN];
    [Addbtn autopinedge:aledgetop toedge:aledgebottom Ofview:tableview withoffset:10];
    [Addbtn autosetdimension:aldimensionwidth tosize:50];
    [Addbtn autosetdimension:aldimensionheight tosize:50];
[Addbtn autoalignaxistosuperviewaxis:alaxisvertical];

 }

And then we started to build the cell model and model.

TimeSwitchModel.h file:

#import <Foundation/Foundation.h>

@interface timeswitchmodel:nsobject
@property (nonatomic,copy) NSString *idstr;
@property (nonatomic,copy) nsstring *namestr;
@property (nonatomic,copy) nsstring *datastr;
@end

TimeSwitchCell.h file

#import <UIKit/UIKit.h>
@class Timeswitchmodel;

@interface Timeswitchcell:uitableviewcell
@property (nonatomic,strong) Timeswitchmodel *model;
@property (nonatomic,copy) void (^deleteclick) (NSString *);
@end

TIMESWITCHCELL.M file

#import "TimeSwitchCell.h" #import "TimeSwitchModel.h" @interface Timeswitchcell () {Uiimageview *_headpicimageview;

    }-(void) Initview {_headpicimageview=[[uiimageview alloc]init];

    [Self.contentview Addsubview:_headpicimageview];
    _deletebtn=[uibutton Buttonwithtype:uibuttontypecustom];

    [Self.contentview ADDSUBVIEW:_DELETEBTN];
    _namelabel=[[uilabel Alloc]init];

    [Self.contentview Addsubview:_namelabel];
    _datelabel=[[uilabel Alloc]init];
[Self.contentview Addsubview:_datelabel];

    }-(void) Setmodel: (Timeswitchmodel *) model {_model=model; _deletebtn.frame=cgrectmake (-79, 0, 79, 80);
    [_deletebtn setimage:[uiimage imagenamed:@ "Delete_icon.png"] forstate:uicontrolstatenormal];
    [_deletebtn setimage:[uiimage imagenamed:@ "Delete_highlight_icon.png"] forstate:uicontrolstatehighlighted];

    [_deletebtn addtarget:self Action: @selector (Deletebtnclick:) forcontrolevents:uicontroleventtouchupinside];
    _headpicimageview.image=[uiimage imagenamed:@ "Timeswich_head_icon.png"];

    _headpicimageview.frame=cgrectmake (8, 12, 56, 56);
    _namelabel.font=[uifont Systemfontofsize:17];
    _namelabel.textcolor=jycolor (109, 109, 109, 1);
    _namelabel.frame=cgrectmake (72, 16, 300, 30);

    _NAMELABEL.TEXT=MODEL.NAMESTR;
    _datelabel.font=[uifont systemfontofsize:15];
    _datelabel.textcolor=jycolor (255, 128, 3, 1);
    _datelabel.frame=cgrectmake (72, 50, 300, 30);

_DATELABEL.TEXT=MODEL.DATASTR;
    }-(void) Deletebtnclick: (UIButton *) idstr {if (Self.deleteclick) {Self.deleteclick (_MODEL.IDSTR); }}-(void) setediting: (BOOL) Editing animateD: (BOOL) animated{if (self.editing = = editing) {return;
} [Super Setediting:editing animated:animated]; CGFloat movespace = 79-38;//cell edit mode will help you move automatically 38 so we'll move on. 79-38 if (self.editing) {[_headpicimagevie W Setframe:cgrectmake (_headpicimageview.frame.origin.x + Movespace, _HEADPICIMAGEVIEW.FRAME.ORIGIN.Y, _

        Namelabel.frame.size.width, _namelabel.frame.size.height)]; [_datelabel setframe:cgrectmake (_datelabel.frame.origin.x + Movespace, _DATELABEL.FRAME.ORIGIN.Y, _

    Datelabel.frame.size.width, _datelabel.frame.size.height)]; }else {[_headpicimageview setframe:cgrectmake (_heaDpicimageview.frame.origin.x-movespace, _HEADPICIMAGEVIEW.FRAME.ORIGIN.Y, _headpicimageview.frame.size.width, _
        HeadpicImageview.frame.size.height)]; [_deletebtn Setframe:cgrectmake (_deletebtn.frame.origin.x-movespace, _DELETEBTN.FRAME.ORIGIN.Y, _
        Deletebtn.frame.size.width, _deletebtn.frame.size.height)]; [_namelabel Setframe:cgrectmake (_namelabel.frame.origin.x-movespace, _NAMELABEL.FRAME.ORIGIN.Y, _

    Datelabel.frame.size.width, _datelabel.frame.size.height)];
 }
}

In Uitableviw, we use a block to enter the model ID of which cell we clicked.

-(UITableViewCell *) TableView: (UITableView *) TableView Cellforrowatindexpath: (Nsindexpath *) IndexPath {

    static NSString *identifier=@ "Timewsitch";
    Timeswitchcell *cell = [TableView dequeuereusablecellwithidentifier:identifier];

    if (cell==nil) {
        Cell=[[timeswitchcell alloc]initwithstyle:uitableviewcellstyledefault reuseIdentifier: identifier];
    }
    Timeswitchmodel *model=[[timeswitchmodel Alloc]init];
    model.idstr=[@ "stringbyappendingstring:[nsstring" stringwithformat:@ "%ld", (long) indexpath.row]];
    model.namestr=@ "Here is the name of the product";
    model.datastr=@ "2017/01/24";
    Cell.model=model;
    cell.deleteclick=^ (NSString * idstr) {
         NSLog (@ "-IDSTR is:%@", idstr);

    return cell;
}

OK, run it and see the effect:
