我在UIscroll视图中有很多UItextViews。当用户按下按钮时,他应该能够点击这些UItextView中的一个,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:1,2,3。然后我使用轻击手势手势来检测触摸视图的标记:
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。这是为什么?
答案 0 :(得分:0)
我终于想出了如何确定标签:
if (txt.tag == [(UIGestureRecognizer *)recognizer view].tag) {
...
基本上这是确定它的代码:
[(UIGestureRecognizer *)recognizer view].tag
