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 Interface Builder。当应用程序加载时，我可以看到我的文本字段和按钮。该按钮在触摸时执行其默认切换行为。文本字段不可编辑 - 无法通过单击调出键盘，无法输入等。

我确实运行了某人的方法来确定一个框架是否超出了其父 View 的范围，但它返回说它超出了范围 - 但我不太确定如何解决这个问题。

Answer 1

googleMapView 有一个阻止所有用户输入的 BlockingGestureRecognizer。不要将文本字段添加到 map 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];
            }
        }
    }
}
