这是我的头文件：

#import <UIKit/UIKit.h>
#import <CoreLocation/CoreLocation.h>
@interface MyLocationViewController : UIViewController <CLLocationManagerDelegate, UITextFieldDelegate>
@property (nonatomic, retain) UITextField *textField;
@end

我没有使用界面生成器。当应用程序加载时，我可以看到我的文本字段和按钮。触摸按钮时会执行其默认切换行为。文本字段不可编辑 - 无法通过单击键盘调出键盘，无法键入等。

我确实运行了某人的方法来确定框架是否超出其父视图的边界，并且它返回说它超出了边界 - 但我不太确定如何解决这个问题。

Answer 1

googleMapView有一个BlockingGestureRecognizer，可以阻止所有用户输入。 不要将文本字段添加到地图或删除阻止程序：

// Remove the GMSBlockingGestureRecognizer of the GMSMapView.
+ (void)removeGMSBlockingGestureRecognizerFromMapView:(GMSMapView *)mapView
{
    if([mapView.settings respondsToSelector:@selector(consumesGesturesInView)]) {
        mapView.settings.consumesGesturesInView = NO;
    }
    else {
        for (id gestureRecognizer in mapView.gestureRecognizers)
        {
            if (![gestureRecognizer isKindOfClass:[UILongPressGestureRecognizer class]])
            {
                [mapView removeGestureRecognizer:gestureRecognizer];
            }
        }
    }
}

Answer 2

如果需要在 uitextfield 中启用触摸事件，请添加此内容

for (id gestureRecognizer in mapView_.gestureRecognizers)
    {
        NSLog(@"mapview recognizer %@",gestureRecognizer);
        if (![gestureRecognizer isKindOfClass:[UILongPressGestureRecognizer class]])
        {
            [mapView_ removeGestureRecognizer:gestureRecognizer];
        }
    }

Answer 3

将 UITextfield 或 UISearchbar 添加到Mapview_的子视图中

UISearchBar *search;
search = [[UISearchBar alloc] init];
    [search setTintColor:[UIColor colorWithRed:233.0/255.0
                                         green:233.0/255.0
                                          blue:233.0/255.0
                                         alpha:1.0]];
    search.frame = CGRectMake(50,20,self.view.frame.size.width-70,32);
    search.delegate = self;
    search.placeholder = @"MapView";
[mapView_ addSubview:search];

将以下方法添加到 .m 文件

// Remove the GMSBlockingGestureRecognizer of the GMSMapView.
+ (void)removeGMSBlockingGestureRecognizerFromMapView:(GMSMapView *)mapView
{
    for (id gestureRecognizer in mapView.gestureRecognizers)
    {
        NSLog(@"mapview recognizer %@",gestureRecognizer);
        if (![gestureRecognizer isKindOfClass:[UILongPressGestureRecognizer class]])
        {
            [mapView removeGestureRecognizer:gestureRecognizer];
        }
    }
}

从您的视图调用此方法将出现

- (void)viewWillAppear:(BOOL)animated {
    [ViewController removeGMSBlockingGestureRecognizerFromMapView:mapView_];
}

现在它可以工作了，我只用这段代码进行了测试。

试试

[self.view addSubview: textField];  

而不是

[mapView_ addSubview:textField];  

这可能会对您有所帮助。
