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

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

直接用圖片的方式是最簡單的設(shè)置一個背景圖拖一個UIImageView到你的CustomCell中去設(shè)置普通和高亮情況下的p_w_picpath針對iOS7修改內(nèi)部元素的frame設(shè)置默認的北京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。

我在另一個文章里看到的方法確實通過自己寫代碼來實現(xiàn)大部分功能我覺得相對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
