（IOS）使用performSelector:withObjec

// 方法一、

// 把参数放进一个数组／字典，直接把数组／字典当成一个参数传过去，具体方法实现的地方再解析这个数组／字典

NSArray* array =

[NSArray arrayWithObjects: @"first", @"second", nil];

[selfperformSelector:@selector(fooFirstInput:) withObject: array afterDelay:15.0];

// 方法二、

// 使用NSInvocation

SEL aSelector = NSSelectorFromString(@"doSoming:argument2:");

NSIntegerargument1 =10;

NSString*argument2 =@"argument2";

if([selfrespondsToSelector:aSelector]) {

    NSInvocation *inv = [NSInvocation invocationWithMethodSignature:[selfmethodSignatureForSelector:aSelector]];

    [inv setSelector:aSelector];

    [inv setTarget:self];

    [inv setArgument:&(argument1) atIndex:2];

    [inv setArgument:&(argument2) atIndex:3];

    [inv performSelector:@selector(invoke) withObject:nilafterDelay:15.0];

}
