我正在开发应用程序，其中子视图四个UIVIEW添加TapGestureRecognition. 但选择器仅适用于第四个视图。谁能告诉我我的逻辑哪里错了。
这是代码在viewdidload我动态创建四个视图中。
Where imageframe and contentarea is Uiview:
contentarea addsubview imageframe.
self.view addsubview contentarea
rect =CGRectMake(0,0 , 160, 230);
view1 = [[UIView alloc]initWithFrame:rect];
view1.backgroundColor=[UIColor greenColor];
view1.tag=viewtag;
[view1.layer setBorderColor: [[UIColor darkGrayColor] CGColor]];
[view1.layer setBorderWidth: 0.5];
[self.imageFrame addSubview:view1];
rect =CGRectMake(161,0, 159, 230);
view2 = [[UIView alloc]initWithFrame:rect];
view2.tag=viewtag+1;
view2.backgroundColor=[UIColor blueColor];
[view2.layer setBorderColor: [[UIColor darkGrayColor] CGColor]];
[view2.layer setBorderWidth: 0.5];
[self.imageFrame addSubview:view2];
rect =CGRectMake(0,231 , 160, 230);
view3 = [[UIView alloc]initWithFrame:rect];
view3.tag=viewtag+2;
view3.backgroundColor=[UIColor redColor];
[view3.layer setBorderColor: [[UIColor darkGrayColor] CGColor]];
[view3.layer setBorderWidth: 0.5];
[self.contentArea addSubview:view3];
rect =CGRectMake(161,231 , 169, 230);
view4 = [[UIView alloc]initWithFrame:rect];
view4.tag=viewtag+3;
view4.backgroundColor=[UIColor redColor];
[view4.layer setBorderColor: [[UIColor darkGrayColor] CGColor]];
[view4.layer setBorderWidth: 0.5];
[self.contentArea addSubview:view4];
UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(oneTap:)];
[singleTap setNumberOfTapsRequired:1];
[singleTap setNumberOfTouchesRequired:1];
[view1 addGestureRecognizer:singleTap];
[view2 addGestureRecognizer:singleTap];
[view3 addGestureRecognizer:singleTap];
[view4 addGestureRecognizer:singleTap];
