我在UIscroll視圖中有很多UItextViews。當用戶按下一個按鈕時,他應該能夠點擊其中一個UItextView,並根據他觸摸的文本視圖來選擇文本。由於我的UItextViews數量取決於每個用戶,我將它們分配給一個整數的標籤:1,2,3。然後,我用自來水姿態的姿態來檢測觸摸視圖的標籤:確定點擊UItextView的標籤
UITapGestureRecognizer *myLongPressRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(leftSwipe:)];
//[myLongPressRecognizer setDirection:(UISwipeGestureRecognizerDirectionUp)];
[textname addGestureRecognizer:myLongPressRecognizer];
- (void)leftSwipe:(UITapGestureRecognizer *)recognizer {
id sender;
UITextView *txtChoosen = (UITextView*) sender;
for (UITextView* txt in textnameArray) {
NSLog(@"%djjjjjjj, %d", txtChoosen.tag, txt.tag);
if (txt.tag == txtChoosen.tag) {
txt.layer.borderWidth = 5.0f;
txt.layer.borderColor = [[UIColor whiteColor] CGColor];
}else{
txt.layer.borderWidth = 0.0f;
txt.layer.borderColor = [[UIColor whiteColor] CGColor];
}}
...
我的問題是,txtChoosen.tag總是等於零。爲什麼是這樣?
