ios自定义类(UIView)代码生成简单的UITableViewCell

由于一个项目中有大量的UITableViewCell需要书写,样式差不多都是 文字介绍:显示内容 这样的。自己又懒得写UITableViewCell类嫌没必要;在方法tableView:cellForRowAtIndexPath中手写又繁琐。就封装变化写了一个UIView类。

构思:首先由于文字介绍显示内容的宽度固定,然后Cell的一行(Cell可以包括多行)高度就是文字介绍显示内容所需要的高度两者相比高一些的。下一行就是高度累加重复;Cell的最上端和最下端给个高度;最下端再画个间隔。

一、UITableViewCell自定义类CommonTableViewCellView

1、CommonTableViewCellView.h

#import <UIKit/UIKit.h>// 传递参数自动布局UITableViewCell, 样式:  lable:Value 用法:参考viewController@interface CommonTableViewCellView : UIView{    UIColor *_cellViewColor;// cell颜色,保留项,需要时写个方法    CGFloat _labelSpace;// lable宽度,保留项,需要时写个方法    CGFloat _viewHeight;}@property (nonatomic,retain) UIColor *cellViewColor;@property (nonatomic,assign) CGFloat labelSpace;@property (nonatomic,assign) CGFloat viewHeight;- (id)initWithFrame:(CGRect)frame keyArray:(NSArray*)keyArray valueArray:(NSArray*)valueArray;@end

2、CommonTableViewCellView.m

#import "CommonTableViewCellView.h"#define topBottomSpace_ 10.0f#define labelSpace_ 100.0f#define contentWidthSpace_ self.frame.size.width - labelSpace_ - leftSpace_ - rightSpace_#define contentHeightSpace_ 20.0f#define leftSpace_ 20.0f#define rightSpace_ 5.0f@implementation CommonTableViewCellView@synthesize cellViewColor = _cellViewColor;@synthesize labelSpace = _labelSpace;@synthesize viewHeight = _viewHeight;-(void)dealloc{        self.cellViewColor = nil;    [super dealloc];}- (id)initWithFrame:(CGRect)frame keyArray:(NSArray*)keyArray valueArray:(NSArray*)valueArray;{    self = [super initWithFrame:frame];    if (self) {        self.labelSpace = labelSpace_;        self.cellViewColor = [UIColor clearColor];                self.viewHeight = topBottomSpace_;        int count = keyArray.count>valueArray.count ? keyArray.count :valueArray.count;        for (int i = 0;i < count; i++) {            self.viewHeight = [self rectUIView:self.viewHeight labelText:[keyArray objectAtIndex:i] text:[valueArray objectAtIndex:i]];        }        self.viewHeight += topBottomSpace_;        // 横 分割线        UIImageView *imgView_H = [[UIImageView alloc]initWithFrame:CGRectMake( 0, self.viewHeight-1, self.frame.size.width, 1)];        imgView_H.backgroundColor = [UIColor colorWithRed:221/255.0f green:221/255.0f blue:221/255.0f alpha:1.0];        [self addSubview:imgView_H];        [imgView_H release];        [self setFrame:CGRectMake(0, frame.origin.y, self.frame.size.width, self.viewHeight)];    }    return self;}// 重置高度-(CGFloat)resizeViewHeight:(NSString *)text width:(CGFloat)width height:(CGFloat)height{        CGSize constraint = CGSizeMake(width, 2000.0f);    CGSize size = [text sizeWithFont:[UIFont systemFontOfSize:13.0f] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap];    return size.height>height?size.height:height;}// 行-(CGFloat)rectUIView:(CGFloat)height labelText:(NSString*)labelText text:(NSString*)text{        CGFloat textValueHeight = [self resizeViewHeight:text width:contentWidthSpace_ height:contentHeightSpace_];    CGFloat labelTextHeight = [self resizeViewHeight:labelText width:self.labelSpace height:contentHeightSpace_];    CGFloat cellHeight = textValueHeight>labelTextHeight ? textValueHeight : labelTextHeight;        UILabel *label = [self rectUILabel:labelText rect:CGRectMake(leftSpace_, height, self.labelSpace, cellHeight)];    [self addSubview:label];        UILabel *textValueLabel = [self rectUILabel:text rect:CGRectMake(self.labelSpace + leftSpace_, height, contentWidthSpace_, cellHeight)];    [self addSubview:textValueLabel];        return height + cellHeight ;}// 列- (UILabel *)rectUILabel:(NSString *)text rect:(CGRect)rect{    UILabel *label = [[UILabel alloc] initWithFrame:rect];    label.backgroundColor = self.cellViewColor;    label.textAlignment = UITextAlignmentLeft;    label.lineBreakMode = UILineBreakModeWordWrap;    label.numberOfLines = 0;    label.font = [UIFont systemFontOfSize:13.0];    label.text = text;    return [label autorelease];}@end

二、UIViewController调用

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{        UITableViewCell *cell = [self tableView:tableView cellForRowAtIndexPath:indexPath];    CGFloat height = cell.frame.size.height;    return height;}- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {    static NSString *CellIdentifier = @"Cell";    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];    if (cell == nil) {        cell = [[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier ] autorelease];                UIView *view = [[[UIView alloc] init] autorelease];        CGFloat viewHeight = 0.0f;        for (int i=0 ; i < 5 ; i++) {                        NSMutableArray *keyArray = [NSMutableArray arrayWithObjects:@"文字介绍1:",@"文字介绍2:",@"知道你过得不好 我也就安心了3:", nil];            NSMutableArray *valueArray = [NSMutableArray arrayWithObjects:[NSString stringWithFormat:@"随机数据%d", arc4random_uniform(100)],[NSString stringWithFormat:@"生活就像一盒巧克力 你永远不知道你会得到什么%d", arc4random_uniform(100)],[NSString stringWithFormat:@"随机数据%d", arc4random_uniform(100)], nil];            CommonTableViewCellView *cellView = [[[CommonTableViewCellView alloc] initWithFrame:CGRectMake(0, viewHeight, self.view.frame.size.width, 0) keyArray:keyArray valueArray:valueArray] autorelease];            viewHeight += cellView.viewHeight;            [view addSubview:cellView];        }        [view setFrame:CGRectMake(0, 0, self.view.frame.size.width, viewHeight)];        cell.accessoryView = view;        [cell setFrame:CGRectMake(0, 0, self.view.frame.size.width, viewHeight)];        cell.selectionStyle = UITableViewCellSelectionStyleNone;    }    return cell;}

三、有图有真相
