在appdelegate中实现委托:

// AppDelegate.h

#import
<UIKit/UIKit.h> #import "FunctionTest.h"
@class ViewController;
@interface AppDelegate : UIResponder
<UIApplicationDelegate,FunctionTestDelegate> {
FunctionTest *test;
}
@property (strong, nonatomic) UIWindow *window;
@property (strong, nonatomic) ViewController *viewController;
@end
AppDelegate.m中实现:
[java] view plaincopyprint?
#pragma mark -FunctionTestDelegate
- (void)func3
{
NSLog(@"function 3 called
ns");
}
- (void)func4
{
NSLog(@"function 4 called
ns");
}
在
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
调用添加:
[java] view plaincopyprint?
test = [[FunctionTest alloc]init];
test.delegate = self;
[test func1];
[test func2];
