我使用下面的代码来添加强制触摸预览操作… Peek和pop视图效果很好,只有动作没有显示…请帮助我的代码由于某种原因没有被执行,看看：
- (NSArray<id<UIPreviewActionItem>> *)previewActionItems {
if (_previewActions == nil) {
UIPreviewAction *rateAction = [UIPreviewAction actionWithTitle:@"Rate" style:UIPreviewActionStyleDefault handler:^(UIPreviewAction * _Nonnull action,UIViewController * _Nonnull previewViewController) {
EmbededRateViewController *embededRVC = [[EmbededRateViewController alloc]initWithEmployerToRate:self.employersArray[0]];
embededRVC.view.bounds = CGRectMake(0,self.view.frame.size.width - 40,210);
[embededRVC setPopinTransitionStyle:BKTPopinTransitionStyleSnap];
BKTBlurParameters *blurParameters = [[BKTBlurParameters alloc] init];
blurParameters.tintColor = [UIColor colorWithWhite:0 alpha:0.5];
blurParameters.radius = 0.3f; // 0.3
[embededRVC setBlurParameters:blurParameters];
[embededRVC setPopinTransitionDirection:BKTPopinTransitionDirectionTop];
[self.collectionView setScrollEnabled:NO];
[self presentPopinController:embededRVC animated:YES completion:^{
NSLog(@"Popin presented !");
}];
}];
UIPreviewAction *commentAction = [UIPreviewAction actionWithTitle:@"Comment" style:UIPreviewActionStyleDefault handler:^(UIPreviewAction * _Nonnull action,UIViewController * _Nonnull previewViewController) {
NewCommentViewController *ncvc = [[NewCommentViewController alloc]initWithEmployer:self.employersArray[0]];
[self presentViewController:ncvc animated:YES completion:nil];
}];
UIPreviewAction *reportAction = [UIPreviewAction actionWithTitle:@"Report" style:UIPreviewActionStyleDestructive handler:^(UIPreviewAction * _Nonnull action,UIViewController * _Nonnull previewViewController) {
ReportEmployerViewController *reportEmpVC = [[ReportEmployerViewController alloc]initWithEmployer:self.employersArray[0]];
[self presentViewController:reportEmpVC animated:YES completion:nil];
}];
UIPreviewAction *cancelAction =
[UIPreviewAction actionWithTitle:@"Cancel"
style:UIPreviewActionStyleSelected
handler:^(UIPreviewAction *action,UIViewController *previewViewController){
}];
_previewActions = @[commentAction,rateAction,reportAction,cancelAction];
}
return _previewActions;
}
解决方法
我面临同样的问题被困了很长时间.
我犯的错误是在Caller View Controller中添加了这个方法. 例如,如果您在强制触摸View Controller A(调用者)时呈现View Controller B(调用),则将此方法添加到View Controller B(调用). 并且太明显了,因为我们正在处理View控制器B中的按钮操作. 希望它能帮到你.祝一切顺利. （编辑：李大同） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
