先看兩個代碼的不同：

for (UIView *view in [self.RowTableView subviews]) {

? ? ? ? ? ? UITapGestureRecognizer *singleTapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(singleTap:)];

? ? ? ? ? ? [singleTapGestureRecognizer setNumberOfTapsRequired:1];

? ? ? ? ? ? [view addGestureRecognizer:singleTapGestureRecognizer];

? ? ? ? ? ? view.backgroundColor = [UIColor blackColor];

? ? ? ? }

UITapGestureRecognizer *singleTapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(singleTap:)];

? ? ? ? for (UIView *view in [self.RowTableView subviews]) {

? ? ? ? ? ? [singleTapGestureRecognizer setNumberOfTapsRequired:1];

? ? ? ? ? ? [view addGestureRecognizer:singleTapGestureRecognizer];

? ? ? ? ? ? view.backgroundColor = [UIColor blackColor];

? ? ? ? }

原因：

多個UIView添加同一個手勢只有最后一個有用

所以只要創建多個手勢? 共用一個手勢方法即可

所以第一個方式有效

移除手勢

UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] init];

? ? if (did_delectBtn) {

? ? ? ? for (UIView *view in [self.RowTableView subviews]) {

? ? ? ? ? ? UITapGestureRecognizer *singleTapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(singleTap:)];

? ? ? ? ? ? tap = singleTapGestureRecognizer;

? ? ? ? ? ? [singleTapGestureRecognizer setNumberOfTapsRequired:1];

? ? ? ? ? ? [view addGestureRecognizer:singleTapGestureRecognizer];

? ? ? ? ? ? view.backgroundColor = [UIColor blackColor];

? ? ? ? }

? ? }else{

? ? ? ? for (UIView *view in [self.RowTableView subviews]) {

? ? ? ? ? ? [view removeGestureRecognizer:tap];

? ? ? ? }

? ? }
