ios - textFieldShouldBeginEditing 没有响应

Question

#import <UIKit/UIKit.h>
#import "HZAreaPickerView.h"

@interface CodeNumberViewController : UIViewController<UITextFieldDelegate, HZAreaPickerDelegate>
@property (weak, nonatomic) IBOutlet UITextField *areaText;
@property (weak, nonatomic) IBOutlet UITextField *cityText;


@property (strong, nonatomic) NSString *areaValue, *cityValue;
@property (strong, nonatomic) HZAreaPickerView *locatePicker;

-(void)cancelLocatePicker;
@end

----------------下面的.m文件----------------

#pragma mark - TextField delegate
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{
    if ([textField isEqual:self.areaText]) {
        [self cancelLocatePicker];
        self.locatePicker = [[HZAreaPickerView alloc] initWithStyle:HZAreaPickerWithStateAndCityAndDistrict delegate:self];
        [self.locatePicker showInView:self.view];
    } else {
        [self cancelLocatePicker];
        self.locatePicker = [[HZAreaPickerView alloc] initWithStyle:HZAreaPickerWithStateAndCity delegate:self];
        [self.locatePicker showInView:self.view];
    }
    return NO;
}

当我点击 UITextField 时，我发现 textFieldShouldBeginEditing 甚至没有被调用。怎么了？我已经将 UITextField 连接到 .h 文件。

我真的希望你能帮忙，如果你需要更多细节，我会补充，不要减去我的声誉，因为我没有太多。谢谢

我猜你没有在你的 viewDidLoad 集中设置委托(delegate):

self.areaText.delegate = self;

self.cityText.delegate = self;
