iOS中tableView cell分割线的一些设置技巧

if ([self.tableView respondsToSelector:@selector(setSeparatorInset:)]) {
  
  [self.tableView setSeparatorInset:UIEdgeInsetsMake(0, 45, 0, 0)];
  
 }

[self.tableView setSeparatorColor:[UIColor clearColor]];

typedef NS_ENUM(NSInteger, UITableViewCellSeparatorStyle) {
 UITableViewCellSeparatorStyleNone,
 UITableViewCellSeparatorStyleSingleLine,
 UITableViewCellSeparatorStyleSingleLineEtched // This separator style is only supported for grouped style table views currently
};

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
 UITableViewCell *cell = nil;
 cell = [tableView dequeueReusableCellWithIdentifier:@"cell"];
 if (cell == nil) {
  cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:@"cell"];
  cell.accessoryView = [[UIImageView alloc]initWithImage:[UIImage imageNamed:@"huicellacce"]];
  cell.backgroundColor = [UIColor clearColor];
//  cell.selected = YES;
  UIImageView *imageViewSepE = [[UIImageView alloc]initWithFrame:CGRectMake(47, 49, 200, 1)];
  imageViewSepE.image = [UIImage imageNamed:@"godline"];
  [cell.contentView addSubview:imageViewSepE];

 }
}

- (void)drawRect:(CGRect)rect { 
CGContextRef context = UIGraphicsGetCurrentContext(); 
CGContextSetFillColorWithColor(context, [UIColor clearColor].CGColor); CGContextFillRect(context, rect); 

CGContextSetStrokeColorWithColor(context, [UIColorcolorWithHexString:@"ffffff"].CGColor)；
 CGContextStrokeRect(context, CGRectMake(5, -1, rect.size.width - 10, 1)); //下分割线 
CGContextSetStrokeColorWithColor(context, [UIColor colorWithHexString:@"e2e2e2"].CGColor); 
CGContextStrokeRect(context, CGRectMake(5, rect.size.height, rect.size.width - 10, 1));
 }
