【移動(dòng)應(yīng)用開發(fā)技術(shù)】iOS7UITableView做成類似iOS6風(fēng)格

iOS7扁平化設(shè)計(jì)已經(jīng)成為了一個(gè)趨勢基于對(duì)老版本的臨時(shí)修改UITableView在sytle是group的時(shí)候是個(gè)×××煩沒辦法改就改吧。

直接用圖片的方式是最簡單的設(shè)置一個(gè)背景圖拖一個(gè)UIImageView到你的CustomCell中去設(shè)置普通和高亮情況下的p_w_picpath針對(duì)iOS7修改內(nèi)部元素的frame設(shè)置默認(rèn)的北京view為空代碼如下-(UITableViewCell*)tableView:(UITableView*)tableViewcellForRowAtIndexPath:(NSIndexPath*)indexPath

{

UIView*testView2=[[UIViewalloc]init];

testView2.backgroundColor=UIColor.clearColor;

cell.selectedBackgroundView=testView2;

}這樣基本就OK了。

我在另一個(gè)文章里看到的方法確實(shí)通過自己寫代碼來實(shí)現(xiàn)大部分功能我覺得相對(duì)比較好但是很多陰影效果還是需要在研究研究的。主要是修改customcell的setFrame,和修改tableview的willDisplayCell來看看這兩段代碼//custom重寫setFrame方法當(dāng)然該方法最好針對(duì)iOS7才有效。#defineIOS7_OR_LATER([[[UIDevicecurrentDevice]systemVersion]compare:@"7.0"]!=NSOrderedAscending)

-(void)setFrame:(CGRect)frame{

if(IOS7_OR_LATER){

NSIntegerinset=10;

frame.origin.x+=inset;

frame.size.width-=2*inset;

}

[supersetFrame:frame];

}然后寫UITableViewDelegate的回調(diào)函數(shù)-(void)tableView:(UITableView*)tableViewwillDisplayCell:(UITableViewCell*)cellforRowAtIndexPath:(NSIndexPath*)indexPath
