UITableViewCell子类-特定位置的背景

好的,现在我知道您想要重新设计分组表视图。 Download (mediafire.com 55kb)

代码如下:

#define numberOfRows 5

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    return 2;
}

- (NSInteger)tableView:(UITableView *)table numberOfRowsInSection:(NSInteger)section {
    return numberOfRows;
}

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
    if (indexPath.row == 0)
        return 42;
    else
        return 41;
}

- (UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    static NSString *kCustomCellID = @"CustomCell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:kCustomCellID];
    if (cell == nil)
    {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:kCustomCellID] autorelease];

        UIImage *theIMG;
        if (indexPath.row == 0) // you have to make a fourth image if only one cell exist
            theIMG = [UIImage imageNamed:@"1.png"];
        else if (indexPath.row == numberOfRows -1) // the last cell
            theIMG = [UIImage imageNamed:@"3.png"];
        else
            theIMG = [UIImage imageNamed:@"2.png"];

        UIImageView *mg = [[UIImageView alloc]initWithImage:theIMG];
        cell.backgroundView = mg;
        cell.selectionStyle = UITableViewCellSelectionStyleNone;
    }
    // check out how large your image should be if the table is not over the full screen
    //NSLog(@"Row:%i Width:%f", indexPath.row, cell.backgroundView.frame.size.width);

    cell.backgroundColor = [UIColor clearColor];
    cell.textLabel.text = @"TEXT";
    return cell;
}

您可以使用层来编辑特定的UI元素(默认表视图,未分组)

myTable.layer.cornerRadius = 7.0;
myTable.layer.borderWidth = 1;
myTable.backgroundColor = [UIColor colorWithRed:0.89 green:0.89 blue:0.89 alpha:1.0];

#import <QuartzCore/CAAnimation.h> 并链接QuarzCore.framework(项目目标->常规->添加“-”按钮)

对于箭头,您应该使用图像并替换默认的显示按钮。
