在代码中将UIButton连接到IBOutlet和IBAction

我有这是viewDidLoad：

// Set up register button UIButton *registerButton = [UIButton buttonWithType:UIButtonTypeSystem]; [registerButton setTitle:@"Register" forState:UIControlStateNormal]; registerButton.frame = CGRectMake(0.0, 0.0, self.screenWidth / 2.0, 100.0); 

和这个：

 - (IBAction)buttonPressed:(UIButton *)sender { } 

我的.h文件中也有这个：

 @property (nonatomic, weak) IBOutlet UIButton *registerButton; 

如何将IBOutlets和IBActions连接到我在代码中创建的按钮？

Answer 1

您必须将目标设置为按钮，如下所示：

[registerButton addTarget:self action:@selector(buttonPressed:) forControlEvents:UIControlEventTouchUpInside];

Answer 2

 UIButton *registerButton = [UIButton buttonWithType:UIButtonTypeRoundedRect]; registerButton.frame=CGRectMake(150, 10, 150,25); registerButton.userInteractionEnabled = YES; [registerButton setTitle:@"Register" forState:UIControlStateNormal]; [registerButton addTarget:self action:@selector(buttonPressed:) forControlEvents:UIControlEventTouchUpInside]; [view.contentView addSubview:registerButton]; 

尝试这个。 我认为这对你有用。
