Question

我只是在ViewDidLoad

中为paypal按钮编写代码

UIButton *button = [[PayPal getInstance] getPayButtonWithTarget:self andAction:@selector(payWithPayPal) andButtonType:BUTTON_278x43];

并将崩溃视为以下内容

2011-11-17 05:41:39.541 MothProject[654:707] -[PayPal getPayButtonWithTarget:andAction:andButtonType:andButtonText:]: unrecognized selector sent to instance 0x2bd2d0

我已经在self中使用了所有必需的委托方法，并且也使用了Delegate，

什么是问题，是否有人对此有所了解？

我认为您需要首先使用方法

初始化PayPal的实例

-initializeWithAppID:forEnvironment:

PayPal按钮无法识别的选择器？
