iOS开发_开启关闭侧滑手势
作者:互联网
1、前言
- 在部分页面需要禁止掉手势返回功能,使用父类继承的特性,快速设置开启关闭手势返回功能。
2、头文件
@interface Update_Center_Controller : Basic_Controller
/** 开启关闭侧滑手势, 默认 YES开启 */
@property(nonatomic, assign) BOOL pop_gesture;
@end
3、.m文件
@interface Update_Center_Controller ()
/** 开启关闭侧滑手势专用 */
@property(nonatomic, assign) BOOL gesture_flag;
@end
@implementation Update_Center_Controller
- (void)viewDidLoad {
[super viewDidLoad];
self.pop_gesture = YES;
}
- (void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
if (!self.pop_gesture) {
self.gesture_flag = NO;
if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
self.navigationController.interactivePopGestureRecognizer.delegate = (id)self;
}
}
}
- (void)viewWillDisappear:(BOOL)animated{
[super viewWillDisappear:animated];
if (!self.pop_gesture) {
// 在其他离开改页面的方法同样加上下面两句代码
self.gesture_flag = YES;
if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
self.navigationController.interactivePopGestureRecognizer.delegate = nil;
}
}
}
- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer {
if (!self.pop_gesture) {
// YES:允许右滑返回 NO:禁止右滑返回
return self.gesture_flag;
}
else {
return YES;
}
}
@end
