我在 UIscroll 视图中有许多 UItextViews。当用户按下按钮时,他应该能够点击这些 UItextView 之一,并且根据他触摸的文本视图,将选择其中的文本。由于我的 UItextViews 编号取决于每个用户,因此我为它们分配了一个整数的标签:1、2、3。然后我使用点击手势来检测被触摸视图的标签:
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];
}}
...
我的问题是 txtChoosen.tag 总是等于零。为什么是这样?
