IOS中的target action控件的实现
实现代码：
#import <Foundation/Foundation.h>
@interface Sample : NSObject {
SEL action;
id target;
}
@property SEL action;
@property (assign) id target;
-(void)addTarget:(id) t action:(SEL) s;
-(void)sample_dosomthing;
@end
#import "Sample.h"
@implementation Sample
@synthesize action;
@synthesize target;
-(void)dealloc{
target = nil;
[super dealloc];
}
-(void)addTarget:(id) t action:(SEL) s{
self.action = s;
self.target = t;
}
-(void)sample_dosomthing{
[self.target performSelector:self.action];
}
@end
这是一个例子，在一个UIViewController里面
-(void)control_dosomthing{
NSLog(@"control_dosomthing");
}
- (void)viewDidLoad {
[super viewDidLoad];
Sample *sample1 = [Sample new];
[sample1 addTarget:self action:@selector(control_dosomthing)];
}
