1.事件處理方法
- (void)viewdidload
/** * 重複父類的方法
*/- (void)touchesbegan:(nsset *)touches withevent:(uievent *)event
// 開始觸控
- (void)touchesmoved:(nsset *)touches withevent:(uievent *)event
// 開始移動
- (void)touchesended:(nsset *)touches withevent:(uievent *)event
// 觸控結束
- (void)touchescancelled:(nsset *)touches withevent:(uievent *)event
// 觸控被取消,一定在觸控事件在執行時,才有取消的條件(比如**)
還學到了:
01.// 設定狀態列的背景風格
02.button可以響應多個target事件1
03.設定父檢視的userinteractionenable為no,會影響到其子檢視。和設定alpha類似,當檢視透明時,其子檢視也會發生變化。
2.練習
- (void)viewdidload
- (void)touchesbegan:(nsset *)touches withevent:(uievent *)event
else if ([touch tapcount] == 1 && [touches count] == 2)
*/// 獲取當前位置
_precious = [touch locationinview:self.view];
}// 處理單機&雙擊事件
- (void)touchesended:(nsset *)touches withevent:(uievent *)event
}#pragma mark - private methods
- (void)singletap
- (void)doubletap
3.響應事件者鏈
01.事件傳遞
- (void)viewdidload- (void)test
// 子類化視窗
#import "mywindow.h"
3.事件攔截
userinteractionenabled = no;
hidden = yes;
alpha[[0~0.01]範圍];
4.手勢識別器
- (void)viewdidload
- (void)singletap:(uitapgesturerecognizer *)tap
- (void)doubletap:(uitapgesturerecognizer *)tap
- (void)swipe:(uiswipegesturerecognizer *)swipe
- (void)pan:(uipangesturerecognizer *)pan
// move
- (void)longpress:(uilongpressgesturerecognizer *)lon
else if (lon.state == uigesturerecognizerstateended) else if (lon.state == uigesturerecognizerstatechanged)
}- (void)rotation:(uirotationgesturerecognizer *)rotate
- (void)pinch:(uipinchgesturerecognizer *)pinch
else
}
