我正在使用 .XIB 并且没有 ARC。我将 NSMultableArray 的值传递给另一个视图,如果我放置 [self presentModel...],它可以工作,但是如果我用按钮调用 AnotherView,AnotherView 的 NSMultableArray 的值为 null!
另一个视图.h
@interface AnotherViewController : UIViewController<UITableViewDataSource, UITableViewDelegate>{
NSMutableArray *otherAnother;
NSMutableArray *arrayOfTheAnotherView;
}
@property (retain, nonatomic) IBOutlet UITableView *tableView;
@property (retain, nonatomic) NSMutableArray *arrayOfTheAnotherView;
另一个视图.m
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
otherAnother = [[NSMutableArray alloc]init];
otherAnother = [[NSMutableArray alloc]initWithArray:self.arrayOfTheAnotherView];
// [otherAnother addObjectsFromArray:arrayOfTheAnotherView];
NSLog(@"%@", otherAnother);
NSLog(@"%@", arrayOfTheAnotherView);
NSLog(@"%@", self.arrayOfTheAnotherView);
}
3 NSLog 写了“null”
当前视图.h
@interface CurrentViewController : UIViewController {
NSMutableArray * arrayCurrentView;
AnotherViewController *superAnotherView;
}
@property (retain, nonatomic) AnotherViewController *superAnotherView;
当前视图.m
@synthesize superAnotherView;
NSString *x = [[NSString alloc]initWithFormat:@"%@",[label text]];
arrayCurrentView = [[NSMutableArray alloc]init];
[arrayCurrentView retain];
[arrayCurrentView addObject:x];
self.superAnotherView = [[AnotherViewController alloc]initWithNibName:nil bundle:nil];
self.superAnotherView.arrayOfTheAnotherView = [[NSMutableArray alloc]init];
[self.superAnotherView.arrayOfTheAnotherView retain];
[self.superAnotherView.arrayOfTheAnotherView addObjectsFromArray:arrayCurrentView];
我不知道如何保留 NSMultableArray 的值,谢谢帮助。
