难道我做错了什么？我无法检测到UI
Imageview上的点按. UIImageView * myImage是在storyboard中创建的.代码文件在这里：
https://drive.google.com/folderview?id=0B2jWw-2wZC52NDBFZ2lXUTUzQXM&usp=sharing
文件：ViewController.h
#import <UIKit/UIKit.h> @interface ViewController : UIViewController @property (strong,nonatomic) IBOutlet UIImageView *myImage; @end
文件：ViewController.m
#import "ViewController.h"
@interface ViewController ()
@end
@implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view,typically from a nib.
UIGestureRecognizer *tapGestureRecognizer = [[UIGestureRecognizer alloc] initWithTarget:self action:@selector(tappedImage:)];
[self.myImage addGestureRecognizer:tapGestureRecognizer];
self.myImage.userInteractionEnabled = YES; // default is no for UIImageView
}
- (void)tappedImage:(UIGestureRecognizer *)gestureRecognizer {
//UIImageView *myImage = (UIImageView *)gestureRecognizer.view;
// do stuff;
NSLog(@"it works");
}
@end
解决方法
我认为你应该使用类UITapGestureRecognizer作为：
UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapDetected)]; singleTap.numberOfTapsrequired = 1; preArrowImage.userInteractionEnabled = YES; [preArrowImage addGestureRecognizer:singleTap]; -(void)tapDetected{ NSLog(@"single Tap on imageview"); }
