IOS7相关问题记录
如果使用nav 则很容易与内容值重叠，因此，需要增加这几行代码。关键是这句
self.edgesForExtendedLayout = UIRectEdgeNone;
表示将IOS边框扩展设置为none
- (void)viewDidLoad
{
[super viewDidLoad];
if ([CommonUtil systemVersion] >= 7) {
CGRect frame=self.view.frame;
if (frame.size.height==[[NSUserDefaults standardUserDefaults] floatForKey:@"windowHeight"])
{
frame.size.height-=20;
}
self.view.frame=frame;
self.edgesForExtendedLayout = UIRectEdgeNone;
self.automaticallyAdjustsScrollViewInsets = YES;
self.navigationController.navigationBar.translucent = NO;
self.tabBarController.tabBar.translucent = NO;
}
}

通过cell去找indexPath的方法，原来是这样
SDGroupCell *cell = (SDGroupCell *)[(UIView *)[sender superview]
NSIndexPath *indexPath = [self.baseTableView indexPathForCell:cell];
但实际上，IOS貌似不支持这样查询，要查的话用以下方式
UIView *view = sender;
while (![view isKindOfClass:[UITableViewCell class]]) {
view = [view superview];
}
NSIndexPath *indexPath = [self.baseTableView indexPathForCell:(UITableViewCell *)view];

原来的SDNestedTable的工具类，由于在初次进去的时候无法很好地进行展开cell里的隐藏位置，升到IOS7无法使用，因此要进行修改（红色字）：
//The issue is that expanded index paths are stored in NSDictionary, where NSIndexPath is key. In iOS 7 method -(CGFloat)tableView:heightForRowAtIndexPath: receivesUIMutableIndexPath object instead of NSIndexPath object. So value from dictionary can't be retrieved. Here is this method in SDNestedTableViewController.m:
- (CGFloat) tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
//IOS7 的处理是先获取NSIndexPath 的key 因为在字典里找不到，因此要这样做
NSIndexPath *indexPathKey = [NSIndexPath indexPathForRow:indexPath.row inSection:indexPath.section];
BOOL isExpanded = [[expandedIndexes objectForKey: indexPath] boolValue];
if(isExpanded)
{
//第一次进入时，先看cell的大小是否合适
if(itemCellButtonFisrtDrop == 0){
[self getCellButtonHeight:indexPathKey];
itemCellButtonFisrtDrop ++;
}
return [self geTotleCelltHeight] + 1+30+itemCellButtonViewHeight;
}
return [self geCelltHeight];
}

原来不用加红色这段，都能有导航出来，现在可能要加了
UINavigationController *nav = [[UINavigationControlleralloc]initWithRootViewController:userBillRequestVC];
if ([[UIDevicecurrentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone)
{
[selfpresentModalViewController:nav animated:YES];
}
------------------
uisearchbar 中的层次结构变化了，原来IOS7之前是UISearchBar的subviews是UISearchBarBackground、UISearchBarTextField。而现在IOS7却只有一个uiview，仔细再观察这个uiView，发现苹果将UISearchBarBackground、UISearchBarTextField都封装在一个UIView里，因此，如果要改变其背景图片，可以用以下方法：
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0) {
subviews = [[billSearchBar.subviews objectAtIndex:0] subviews];
}else{
subviews = billSearchBar.subviews;
}
for (UIView *subview in subviews)
{
if ([subview isKindOfClass:NSClassFromString(@"UISearchBarBackground")])
{
[subview removeFromSuperview];
break;
}
}
[searchToolBar addSubview:billSearchBar];
//为UISearchBarTextField设置背景图片
UIView *segment = [subviews count]>0 ? [subviews objectAtIndex:1]: [subviews objectAtIndex:0];
UIImageView *bgImage = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"search_bar_text_bg"]];
[segment addSubview:bgImage];
