方法如下：
第一種解決辦法：
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}
第二種解決辦法：
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}
第三種解決辦法（個人感覺比較簡潔）：
- (void)layoutSubviews{
? ?[super layoutSubviews];
? ? ? ? ?if?(self.isEditing) { ? ? ? ?
? ? ? ? [self sendSubviewToBack:self.contentView];
? ? ? ? }
}
第四種解決辦法：
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}
