新增手勢步驟
初始化手勢 新增手勢觸發呼叫的方法
把手勢新增到檢視上
釋放手勢
1.長按
uilongpressgesturerecognizer *longpress = [[uilongpressgesturerecognizer alloc] initwithtarget:
self
action:
@selector(longpressaction:)];
// 設定長按時間
longpress.minimumpressduration = 2.0;
[imageview addgesturerecognizer:longpress];
[longpress release];
uirotationgesturerecognizer *rotation = [[uirotationgesturerecognizer alloc] initwithtarget:
self
action:
@selector(rotationaciton:)];
[imageview addgesturerecognizer:rotation];
[rotation release];
uipinchgesturerecognizer *pinch = [[uipinchgesturerecognizer alloc] initwithtarget:
self
action:
@selector(pinchaciton:)];
[imageview addgesturerecognizer:pinch];
[pinch release];
uipangesturerecognizer *pan = [[uipangesturerecognizer alloc] initwithtarget:
self
action:
@selector(panaction:)];
[imageview addgesturerecognizer:pan];
[pan release];
uiswipegesturerecognizer *swipe = [[uiswipegesturerecognizer alloc] initwithtarget:
self
action:
@selector(swipeaction:)];
swipe.direction = uiswipegesturerecognizerdirectionleft;
[imageview addgesturerecognizer:swipe];
[swipe release];
uiscreenedgepangesturerecognizer *screenedgepan = [[uiscreenedgepangesturerecognizer alloc] initwithtarget:
self
action:
@selector(screenedgepanaction:)];
// 設定下從哪個邊緣開始掃
screenedgepan.edges = uirectedgeright;
[imageview addgesturerecognizer:screenedgepan];
[screenedgepan release];
實現輕拍方法:
- (void)tapaction:(uitapgesturerecognizer *)tap
