在iOS 6 以前重寫

-(void)willTransitionToState:(UITableViewCellStateMask)state ,發現iOS7 以前的方法不管用了

iOS7 下

在自定義cell裡重寫

-(void)willTransitionToState:(UITableViewCellStateMask)state{

[super willTransitionToState:state];

if((state & UITableViewCellStateShowingDeleteConfirmationMask) == UITableViewCellStateShowingDeleteConfirmationMask){

// [self recurseAndReplaceSubViewIfDeleteConfirmationControl:self.subviews];

[self performSelector:@selector(recurseAndReplaceSubViewIfDeleteConfirmationControl:) withObject:self.subviews afterDelay:0];

}

}

-(void)recurseAndReplaceSubViewIfDeleteConfirmationControl:(NSArray*)subviews{

NSString *delete_button_name = @"delete";

for (UIView *subview in subviews)

{

/**

* iOS 6 以前

*/

if ([NSStringFromClass([subview class]) isEqualToString:@"UITableViewCellDeleteConfirmationControl"])

{

/**

將添加一個視圖來覆蓋默認的控制使用的圖像有一個透明的背景

*/

UIView *backgroundCoverDefaultControl = [[UIView alloc] initWithFrame:CGRectMake(0,0, 64, 33)];

[backgroundCoverDefaultControl setBackgroundColor:[UIColor whiteColor]];

[[subview.subviews objectAtIndex:0] addSubview:backgroundCoverDefaultControl];

UIImage *deleteImage = [UIImage imageNamed:delete_button_name];

UIImageView *deleteBtn = [[UIImageView alloc]initWithFrame:CGRectMake(0, 0,deleteImage.size.width, deleteImage.size.height)];

[deleteBtn setImage:[UIImage imageNamed:delete_button_name]];

}

{

[deleteButton setImage:[UIImage imageNamed:delete_button_name] forState:UIControlStateNormal];

[deleteButton setTitle:@"" forState:UIControlStateNormal];
