我的一个控制器中有以下两种方法.buttonPressed方法连接到按钮并正常工作.但是,当我将调用添加到workWithAString时,出现错误.想知道我在这里失踪了什么,并感谢你的建议.
-(NSString *) workWithAString: (NSString *) string1
{
NSString *string2 = [[NSString alloc] initWithString:string1];
// Here I will do some other things with string2
return string2;
}
-(IBAction)button1Pressed
{
NSString *modifiedString1 = [[NSString alloc] initWithString:InputValue.text];
modifiedString1 = [[self workWithAString: modifiedString1 ]; // Expected identifier error here
}

出于某种原因,你有两个括号......
[self workWithAString:modifiedString1];
