ios UITableview操作
初学ios以及其UITableview控件，使用自定义cell和模型。
自定义模型：
DataModel.h
#ifndef DataModel_h
#define DataModel_h
#import <UIKit/UIKit.h>
@interface DataModel : UIViewController
@property (strong, nonatomic) NSString *name;
@property (strong, nonatomic) NSString *dept;
@property (strong, nonatomic) NSString *image;
- (NSString *)getName;
- (NSString *)getDept;
- (NSString *)getImage;
@end
#endif /* DataModel_h */
DataModel.m
#import <Foundation/Foundation.h>
#import "DataModel.h"
@interface DataModel ()
@end
@implementation DataModel
@synthesize name = _name;
@synthesize dept = _dept;
@synthesize image = _image;
- (NSString *)getName{
return _name;
}
- (NSString *)getDept{
return _dept;
}
- (NSString *)getImage{
return _image;
}
@end
自定义cell：
MyCell.h
#ifndef MyCell_h
#define MyCell_h
#import <UIKit/UIKit.h>
#import "DataModel.h"
@interface MyCell : UITableViewCell
@property(nonatomic,strong)UIView* achievementInfoView;//成果信息view
@property (nonatomic) CGFloat height;//cell的高度
@property(nonatomic,strong)DataModel*dataModel;//自定义数据model
-(void) setCellWithInfo:(DataModel*)dataModel indexPath:(NSIndexPath*)indexPath;
@end
#endif /* MyCell_h */
MyCell.m
#import <Foundation/Foundation.h>
#import "MyCell.h"
#import "UIImageView+WebCache.h"
#import "UIView+XMGExtension.h"
@interface MyCell ()
@end
@implementation MyCell
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {
// Initialization code
[self initSubviews];
}
return self;
}
- (void)initSubviews
{
self.selectionStyle =UITableViewCellSelectionStyleNone;//选中后不变色
self.achievementInfoView = [[UIView alloc] initWithFrame:CGRectZero];//CGRectMake(0,0,0,0)
[self.contentView addSubview:self.achievementInfoView];
self.height = 0;
}
-(void) setCellWithInfo:(DataModel*)dataModel indexPath:(NSIndexPath*)indexPath
{
for(UIView *view in [self.achievementInfoView subviews])
{
[view removeFromSuperview];
}
self.achievementInfoView.frame = CGRectMake(0, 0, 100, 0);
self.dataModel = dataModel;
//头像
UIImageView *paperImageview = [[UIImageView alloc]initWithFrame:CGRectMake(24, 14, 60, 60)];
//设置占位图
[paperImageview sd_setImageWithURL:[NSURL URLWithString:dataModel.image] placeholderImage:[UIImage imageNamed:@"holderPNG"] options:SDWebImageRetryFailed];
paperImageview.layer.cornerRadius = 30;
paperImageview.clipsToBounds = YES;
[self.achievementInfoView addSubview:paperImageview];
//给图片贴上按钮
paperImageview.userInteractionEnabled = YES;
UIButton *imageBtn = [UIButton buttonWithType:UIButtonTypeCustom];
imageBtn.frame = paperImageview.bounds;
imageBtn.backgroundColor = [UIColor clearColor];
[imageBtn addTarget:self action:@selector(imageBtnClick:) forControlEvents:UIControlEventTouchUpInside];
[paperImageview addSubview:imageBtn];
//作者
UILabel *authorLab = [[UILabel alloc]initWithFrame:CGRectMake(24+60+10, paperImageview.y, 200, 30)];
authorLab.font = [UIFont boldSystemFontOfSize:20];
authorLab.text = dataModel.name;
[self.achievementInfoView addSubview:authorLab];
//单位
UILabel *deptLab = [[UILabel alloc]initWithFrame:CGRectMake(24+60+10, paperImageview.y+30, 300, 20)];
deptLab.textColor = [UIColor grayColor];
deptLab.text = dataModel.dept;
[self.achievementInfoView addSubview:deptLab];
//添加按钮
UIButton *addBtn = [UIButton buttonWithType:UIButtonTypeCustom];
addBtn.frame = CGRectMake(24+60+5+200, paperImageview.y+10, 100, 30);
[addBtn setTitle:@"添加" forState:UIControlStateNormal];
[addBtn setTitleColor:UIColor.systemBlueColor forState:UIControlStateNormal];
[addBtn addTarget:self action:@selector(addBtnClick:) forControlEvents:UIControlEventTouchUpInside];
//[self.achievementInfoView addSubview:addBtn];
[self.contentView addSubview:addBtn];
self.achievementInfoView.frame = CGRectMake(0, 0, 100, paperImageview.height);
self.height = self.achievementInfoView.height+24;//设置当前cell高度
}
// 添加按钮点击事件
-(void)addBtnClick:(UIButton *)button{
NSLog(@"点击了cell上的添加按钮");
}
