iOS 修改 TableView 的 delete 按鈕

iOS 修改 TableView 的 delete 按鈕
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

在自訂cell裡重寫

-(void)willTransitionToState:(UITableViewCellStateMask)state{

[superwillTransitionToState:state];

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

// [self recurseAndReplaceSubViewIfDeleteConfirmationControl:self.subviews];

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

}

}

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

NSString *delete_button_name = @"delete";

for (UIView *subviewin subviews)

{

/**

if ([NSStringFromClass([subviewclass]) isEqualToString:@"UITableViewCellDeleteConfirmationControl"])

{

/**

將添加一個視圖來覆蓋預設的控制使用的映像有一個透明的背景

*/

[backgroundCoverDefaultControl setBackgroundColor:[UIColorwhiteColor]];
