iOS 修改 TableView 的 delete 按鈕
-(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]];
[[subview.subviews objectAtIndex:0] addSubview:deleteBtn];
}
/**
* ios7
*/
if ([NSStringFromClass([subview class]) isEqualToString:@"UITableViewCellDeleteConfirmationButton"])
{
UIButton *deleteButton = (UIButton *)subview;
[deleteButton setImage:[UIImage imageNamed:delete_button_name] forState:UIControlStateNormal];
[deleteButton setTitle:@"" forState:UIControlStateNormal];
[deleteButton setBackgroundColor:[UIColor clearColor]];
for(UIView* view in subview.subviews){
if([view isKindOfClass:[UILabel class]]){
[view removeFromSuperview];
}
}
}
if ([NSStringFromClass([subview class]) isEqualToString:@"UITableViewCellDeleteConfirmationView"])
{
for(UIView* innerSubView in subview.subviews){
if(![innerSubView isKindOfClass:[UIButton class]]){
[innerSubView removeFromSuperview];
}
}
}
if([subview.subviews count]>0){
[self recurseAndReplaceSubViewIfDeleteConfirmationControl:subview.subviews];
