推荐答案
如果您在testingViewController和detailView之间使用情节提要，请在testingViewController的prepareForSegue:方法中更改行
If you have a storyboard segue between testingViewController and detailView, in your testingViewController's prepareForSegue: method you should change line
detailView *dVw = [[detailView alloc] init];
到
detailView *dVw = (detailView *)segue.destinationViewController;
此外，我建议您在detailView.h文件中更改
Also, I recommend you to change in your detailView.h file the
@property (nonatomic, assign) NSString *YOUR_STRING;
到
@property (nonatomic, copy) NSString *YOUR_STRING;
