私は使用UITapGestureRecognizerしていて、同じViewControllerで異なるタップを動作させようとしていますが、ワンクリックタップで失敗します。

解決策を見つけようとしましたが、テスト コードに統合できません。そこから学ぶことができるように、これについての助けをいただければ幸いです。

テストに使用しているコードは次のとおりです。

.h ファイル:

@interface ViewController : UIViewController <UIGestureRecognizerDelegate>

.m ファイル:

@interface ViewController ()

@property (nonatomic, strong) UITapGestureRecognizer *tapGestureRecognizer3;
@property (nonatomic, strong) UITapGestureRecognizer *tapGestureRecognizer2;
@property (nonatomic, strong) UITapGestureRecognizer *tapGestureRecognizer1;

@end

@implementation ViewController

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer {

return YES;

}

- (void)viewDidLoad
{
[super viewDidLoad];


self.view.backgroundColor = [UIColor greenColor];

// Create Tap Gesture Recognizer

//==1
self.tapGestureRecognizer1 = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(handle1Taps:)];
self.tapGestureRecognizer1.numberOfTouchesRequired = 1;
self.tapGestureRecognizer1.numberOfTapsRequired = 1;

//==2
self.tapGestureRecognizer2 = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(handle2Taps:)];
self.tapGestureRecognizer2.numberOfTouchesRequired = 1;
self.tapGestureRecognizer3.numberOfTapsRequired = 2;

//== #3
self.tapGestureRecognizer3 = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(handle3Taps:)];
self.tapGestureRecognizer3.numberOfTouchesRequired = 1;
self.tapGestureRecognizer3.numberOfTapsRequired = 3;


[self.tapGestureRecognizer1 requireGestureRecognizerToFail:self.tapGestureRecognizer2];
[self.tapGestureRecognizer1 requireGestureRecognizerToFail:self.tapGestureRecognizer3];
[self.tapGestureRecognizer2 requireGestureRecognizerToFail:self.tapGestureRecognizer3];

// Add gestures
[self.view addGestureRecognizer:self.tapGestureRecognizer1];
[self.view addGestureRecognizer:self.tapGestureRecognizer2];
[self.view addGestureRecognizer:self.tapGestureRecognizer3];

}

- (void)handle1Taps:(UITapGestureRecognizer *)paramSender {
NSLog(@"handle-1-Taps");

NSUInteger touchCounter = 0;

for (touchCounter = 0; touchCounter < paramSender.numberOfTouchesRequired; touchCounter++) {

    CGPoint touchPoint = [paramSender locationOfTouch:touchCounter inView:paramSender.view];

    NSLog(@">>1 x TAP<<");


}

}

- (void)handle2Taps:(UITapGestureRecognizer *)paramSender {
NSLog(@"handle-2-Taps");
NSUInteger touchCounter = 0;

for (touchCounter = 0; touchCounter < paramSender.numberOfTouchesRequired; touchCounter++) {

    CGPoint touchPoint = [paramSender locationOfTouch:touchCounter inView:paramSender.view];

    NSLog(@">>2 x TAP<<");


}

}

- (void)handle3Taps:(UITapGestureRecognizer *)paramSender {
NSLog(@"handle-3-Taps");
NSUInteger touchCounter = 0;

for (touchCounter = 0; touchCounter < paramSender.numberOfTouchesRequired; touchCounter++) {

    CGPoint touchPoint = [paramSender locationOfTouch:touchCounter inView:paramSender.view];

    NSLog(@">>3 x TAP<<");


}

}

@end

以下は、VC との最初の対話の結果です。

 - 1 x tap = >>2 x TAP<<
 - 2 x tap = >>2 x TAP<<
 - 3 x tap = >>3 x TAP<<

ちょっとこれをチェックしてください：最後の行が間違っています。

self.tapGestureRecognizer2 = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(handle2Taps:)];
self.tapGestureRecognizer2.numberOfTouchesRequired = 1;
self.tapGestureRecognizer3.numberOfTapsRequired = 2;

そのはず 

self.tapGestureRecognizer2.numberOfTapsRequired = 2;

これがあなたを助けることを願っています。
