IOS中的target action控件的实现

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)]; 
}
