因为一个项目中有大量的UITableViewCell须要书写,样式几乎相同都是
文字介绍:显示内容 这种。
自己又懒得写UITableViewCell类嫌不是必需;在方法tableView:cellForRowAtIndexPath中手写又繁琐。就封装变化写了一个UIView类。

构思:首先因为文字介绍和显示内容的宽度固定,然后Cell的一行(Cell能够包含多行)高度就是文字介绍和显示内容所须要的高度两者相比高一些的。下一行就是高度累加反复。Cell的最上端和最下端给个高度。最下端再画个间隔。
一、UITableViewCell自己定义类CommonTableViewCellView
1、CommonTableViewCellView.h
#import <UIKit/UIKit.h> // 传递參数自己主动布局UITableViewCell, 样式: lable:Value 使用方法:參考viewController @interface CommonTableViewCellView : UIView{ UIColor *_cellViewColor;// cell颜色,保留项,须要时写个方法 CGFloat _labelSpace;// lable宽度,保留项。须要时写个方法 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 切割线 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; }
