[英]searchBar method doesn't work with my NSMutableArray (Obj-C)
[英]Why doesn't the textfield code work for Xcode 8 Obj-C?
ViewController.h
@interface ViewController : UIViewController{
IBOutlet UITextField *Signup;
IBOutlet UITextField *Login;
}
@property(nonatomic, retain)IBOutlet UITextField *Signup;
@property(nonatomic, retain)IBOutlet UITextField *Login;
-(IBAction)TYPE:(id)sender;
ViewController.m
@synthesize Signup;
@synthesize Login;
-(IBAction)TYPE:(id)sender{
[Signup resignFirstResponder];
[Login resignFirstResponder];
}
在模擬器中,當我單擊文本字段時,出現以下錯誤消息:

我已經有兩年沒有使用Xcode了,但是同樣的代碼可以正常工作,為什么它不能用於Xcode 8,iOS 10?
Xcode 8的模擬器非常冗長。 這些消息並不意味着什么特別。
-順便說一句-
您的代碼以很老的風格編寫,現在不再是最佳實踐。 更好的是:
@interface ViewController : UIViewController
// It's no longer necessary to have your properties between { and }
@property (nonatomic, weak) IBOutlet UITextField *signup;
@property (nonatomic, weak) IBOutlet UITextField *login;
// IBOutlets should be weak, other properties should be weak or strong for objects, or assign for structs and values.
@end
@implementation ViewController
// You don't have to synthesize your properties anymore.
- (IBAction)type:(id)sender {
[self.signup resignFirstResponder];
[_login resignFirstResponder];
// but you do have to either use self. or underscore to refer to them.
}
@end
