方法如下：
第一种解决办法：
01// Fix for iOS7, when backgroundView comes above "delete" button
02- (void)willTransitionToState:(UITableViewCellStateMask)state {
03 [super willTransitionToState:state];
04 [self sendSubviewToBack:self.backgroundView];
05 dispatch_async(dispatch_get_main_queue(), ^{
06 [self sendSubviewToBack:self.backgroundView];
07 });
08}
09
10- (void)didTransitionToState:(UITableViewCellStateMask)state {11 [super didTransitionToState:state];
12 [self sendSubviewToBack:self.backgroundView];
13}
第二种解决办法：
01- (void)layoutSubviews
02{
03 [super layoutSubviews];
04
05 for (UIView *subview in self.subviews) {
06
07
for (UIView *subview2 in subview.subviews) {
08
09 if ([NSStringFromClass([subview2 class]) isEqualToString:@"UITableViewCellDeleteConfirmationView"]) { // move delete confirmation view
10
11 [subview bringSubviewToFront:subview2];12 13 }14 }15}
第三种解决办法（个人感觉比较简洁）：
- (void)layoutSubviews{
[super layoutSubviews];
if (self.isEditing) {
[self sendSubviewToBack:self.contentView];
}
}
第四种解决办法：
1- (void) layoutSubviews {
2 [super layoutSubviews];
3
4 if ([ [ [UIDevice currentDevice] systemVersion] compare: @"7.0" options: NSNumericSearch] != NSOrderedAscending) {
5 if (iOS7 == YES) {
6 self.backgroundView.frame = CGRectMake(0, self.backgroundView.frame.origin.y,
7 self.backgroundView.frame.size.width, self.backgroundView.frame.size.height);
8 }
9}
