iOS 消息处理之performSelector

3个方法

- (id)performSelector:(SEL)aSelector;

- (id)performSelector:(SEL)aSelector withObject:(id)object;

- (id)performSelector:(SEL)aSelector withObject:(id)object1 withObject:(id)object2;

事例：

一：在framework的某个类中，初始化主应用的某个类，并传值给主应用

Class PublicAPIClass = NSClassFromString(@”APIObject”);

if (!PublicAPIClass) {

NSLog(@”Unable to load class”);

// return nil;

}

NSObject *publicAPIObject = [PublicAPIClass new];//初始化

[publicAPIObject performSelector:@selector(SelectorFirstParameter:SecondParameter:) withObject:mDict withObject:self];

二：在主应用的APIObject中

- (void)SelectorFirstParameter:(NSDictionary )dictInfo SecondParameter:(UIViewController )currentView{

}
