在NSThread问题上调用带有两个参数的选择器 [英] calling selector with two arguments on NSThread issue

问题描述

我想创建一个包含多个参数的Thread。
有可能吗？
我有这个函数：

I'd like to make a Thread with multiple arguments. Is it possible? I have the function:

-(void) loginWithUser:(NSString *) user password:(NSString *) password {
}

我想将此函数称为选择器：

And I want to call this function as a selector:

[NSThread detachNewThreadSelector:@selector(loginWithUser:user:password:) toTarget:self withObject:@"someusername" withObject:@"somepassword"]; // this is wrong

如何在此detachNewThreadSelect函数上传递onObject参数的两个参数？

How to pass two arguments on withObject parameter on this detachNewThreadSelect function?

有可能吗？

推荐答案

你需要通过传递给withObject的对象中的额外参数如下：

You need to pass the extra parameters in an object passed to withObject like so:

NSDictionary *extraParams = [NSDictionary dictionaryWithObjects:[NSArray arrayWithObjects:@"user",@"password",nil] andKeys:[NSArray arrayWithObjects:@"valueForUser",@"valueForPassword",nil]]

[NSThread detachNewThreadSelector:@selector(loginWithUser:) toTarget:self withObject:extraParams];
