【11/04】 iOS开发成长之路，【tabelView cell复用】

今天调试程序遇到这么一个警告！

Local declaration of ‘XXX’ hides instance variable

遇到这种原因，是因为本地变量跟函数参数变量同名。开来，还是要注意变量的命名啊！

tableViewcell 去掉横线

隐藏UITableViewCell的分隔线

[self.myTableView       setSeparatorStyle:UITableViewCellSeparatorStyleNone];

textfield 左边距

代理方法实现。要么直接改变textfield的x值

图片自适应大小

iconLeftView.contentMode =UIViewContentModeScaleAspectFit;

tabelView点击之后变灰色 去掉

在 cell alloc之后！！

cell.selectionStyle = UITableViewCellSelectionStyleNone;
cell.selectionStyle = UITableViewCellSelectionStyleNone;
[tableView deselectRowAtIndexPath:indexPath animated:YES];

今天写的类

老大说再改改就能用了。加班改代码中。。。
