使用事件響應鏈處理事件

我們可以借用responder chain實現了乙個自己的事件傳遞鏈。

//uiresponder的分類

//.h檔案
#import
@inte***ce uiresponder (router)-(
void
)routereventwithname:
(nsstring *
)eventname userinfo:
(nsdictionary *
)userinfo;
@end
//.m檔案
#import "uiresponder+router.h"
@implementation uiresponder (router)-(
void
)routereventwithname:
(nsstring *
)eventname userinfo:
(nsdictionary *
)userinfo 
@end

//nsobject

//.h檔案
#import
@inte***ce nsobject (invocation)
-(nsinvocation *
)createinvocationwithselector:
(sel)aselector;
@end
//.m檔案
#import "nsobject+invocation.h"
@implementation nsobject (invocation)
-(nsinvocation *
)createinvocationwithselector:
(sel)aselector 
//3、、建立nsinvocation物件
nsinvocation*invocation =
[nsinvocation invocationwithmethodsignature:signature]
;//4、儲存方法所屬的物件
invocation.target =
self
; invocation.selector = aselector;
return invocation;
}@end

view處理事件

當乙個view需要處理事件的時候 如果我們設定了ontouchlistener，那麼ontouchlistener裡面的ontouch方法會被呼叫，如果ontouch返回false，則當前的view的ontouchevent方法會被呼叫 如果返回值true,那麼ontouchevent方法不會被呼叫...
