关于ios：点击UIButton以编程方式创建另一个UIButton

Tap UIButton to create another UIButton programmatically

我正在尝试以编程方式创建uibutton。我有一个名为"addcash"的按钮(它已经在Interface Builder中创建)，点击这个按钮后，我希望另一个按钮动态显示。当在viewdidload中完成时，这个按钮可以正常工作，但这不是我想要的"addcash"，在创建这个新按钮之前需要点击。这就是我迄今为止所拥有的…

-(IBAction) addCash{
UIButton *theButton = [[UIButton buttonWithType:UIButtonTypeRoundedRect] retain];
theButton.frame = CGRectMake(80, 50, 150, 40);
[theButton setTitle:@"title" forState:UIControlStateNormal];
[theButton addTarget:self action:@selector(test:) forControlEvents:UIControlEventTouchUpInside];
[theButton setBackgroundImage:[UIImage imageNamed:@"edit.jpg"] forState:UIControlStateNormal];

[self.view addSubview:theButton];
}
