IOS UITableView和NavigationBar的常用设置详解

// 清除父类UIEdgeInsets self.tableView.contentInset = UIEdgeInsetsMake(0, 0, 0,0); //禁止滚动 self.tableView.scrollEnabled = NO; // tableview头部视图设置 self.tableView.tableHeaderView =一个UIView; //tableview尾部视图设置，这样用一个不占空间的UIView初始化可以清除尾部多余空格 self.tableView.tableFooterView = [[UIView alloc]initWithFrame:CGRectZero]; //表格背景色 self.tableView.backgroundColor = [UIColorgrayColor]; //取消垂直滚动条 self.tableView.showsVerticalScrollIndicator=NO; //设置表格背景图片 UIView *bgView= [[UIView alloc]initWithFrame:CGRectMake(0,20,SLApplicationW,SLApplicationH)]; UIImageView *bgImageView= [[UIImageView alloc]initWithFrame:CGRectMake(0,0,SLApplicationW,SLApplicationH)];   [bgImageView setImage:[UIImageimageNamed:@"tree"]];   [bgView addSubview:bgImageView]; self.tableView.backgroundView= bgView; 

//表格附件样式,指示箭头     cell.accessoryType=UITableViewCellAccessoryDisclosureIndicator; //禁止点击变色     cell.selectionStyle=UITableViewCellSelectionStyleNone; 

//分割线清偏移   if ([cell respondsToSelector:@selector(setSeparatorInset:)]) {     [cellsetSeparatorInset:UIEdgeInsetsZero];   } 

//分割线清边界（没啥变化）   if ([cell respondsToSelector:@selector(setLayoutMargins:)]) {     [cellsetLayoutMargins:UIEdgeInsetsZero];   } 

//清除父边界   if ([cell respondsToSelector:@selector(setPreservesSuperviewLayoutMargins:)]){     [cellsetPreservesSuperviewLayoutMargins:NO];     }
