objective-c - 如何？我想使用 2 NSMutableData

Question

我想使用 viewDidLoad 中的 2 个 NSMutableData 如何使用它？

@property(strong,nonatomic) id sMemberID;
@property(nonatomic,assign) NSMutableData *receivedData;
@property(nonatomic,assign) NSMutableData *receivedData2;
@property(strong,nonatomic) NSString *statusMem;

Answer 1

假设您有 receiveData 和 receiveData2 在名为 NextViewController 的 ViewController 中，

然后我们可以这样做，

NextViewController *nextViewController = [[NextViewController alloc] initWithNibName:@"NextViewController" bundle:nil];
[nextViewController setReceivedData: sendData1];
[nextViewController setReceivedData2: sendData2];
[self presentViewController:NextViewController animated:YES completion:nil];

也改变非原子，分配给非原子强

@property(nonatomic,strong) NSMutableData *receivedData;
@property(nonatomic,strong) NSMutableData *receivedData2;
