Xcode 5/iOS 7.无法在当前项目中隐藏iOS键盘(xcode 5)
此问题一直让我疯狂,因为现在的一天中有更好的一部分。在我目前的项目中,我无法使用resignFirstResponder隐藏iOS键盘。然而,奇怪的是,我能够在我目前正在进行的所有其他项目中工作。下面的代码。非常感谢,伙计们!
ViewController.h:
#import <UIKit/UIKit.h>
@interface ViewController : UIViewController <UITextFieldDelegate>
{
IBOutlet UISegmentedControl *selectcontrolNumbers;
IBOutlet UILabel *output;
int grossNetVar;
double calcVariable;
IBOutlet UIButton *hideConvertNet;
IBOutlet UIButton *hideConvertGross;
}
@property (strong, nonatomic) IBOutlet UITextField *dollarTextField;
@property (nonatomic)int grossNetVar;
@property (nonatomic) double calcVariable;
- (IBAction)selectAction:(id)sender;
- (IBAction)convertToNet:(id)sender;
- (IBAction)convertToGross:(id)sender;
@end
ViewController.m:
#import "ViewController.h"
@interface ViewController()
@end
@implementation ViewController
@synthesize grossNetVar;
@synthesize calcVariable;
- (void)viewDidLoad
{
[super viewDidLoad];
self.dollarTextField.delegate = self;
}
-(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
[self.dollarTextField resignFirstResponder];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (IBAction)selectAction:(id)sender {
if (selectcontrolNumbers.selectedSegmentIndex == 0){
grossNetVar = 1;
} else {
grossNetVar = 2;
}
if (grossNetVar == 1) {
hideConvertGross.enabled = YES;
hideConvertNet.enabled = NO;
} else {
hideConvertGross.enabled = NO;
hideConvertNet.enabled = YES;
}
}
- (IBAction)convertToNet:(id)sender {
NSString *textFieldText = _dollarTextField.text;
calcVariable = .85;
double dollarTotal = [textFieldText doubleValue];
double netCalc = calcVariable * dollarTotal;
NSString *netString = [[NSString alloc]initWithFormat:@"The NET total is %g", netCalc];
output.text = netString;
}
- (IBAction)convertToGross:(id)sender {
}
@end
创建一个IBAction为是' - (空)的touchesBegan:(NSSet中*)倒是withEvent:方法(*的UIEvent)event'被称为? – nhgrif
是的 - 右下方viewDidLoad – MrShickadance9
正如@nhgrif指出的那样,在那里放置一个断点,看看它是否被调用。 – mostruash
