我需要帮助显示一个字符串,如果If-Else语句显示else,则在另一个View Controller中。我比较新,很抱歉,如果你觉得这很愚蠢。我在ViewControler.m文件中尝试过:
-(IBAction)ButtonTouched:(id)sender
{
[self.InputField resignFirstResponder];
if (NSOrderedSame == [self.InputField.text caseInsensitiveCompare:@"teacher"])
{
_Correct.hidden = FALSE;
_Hider.hidden = TRUE;
_FalseHider.hidden = FALSE;
_SHOWCORRECT.hidden = TRUE;
_CorrectAnswer.hidden = TRUE;
} else {
_FalseHider.hidden = TRUE;
_Correct.hidden = TRUE;
_SHOWCORRECT.hidden = FALSE;
_CorrectAnswer.hidden = TRUE;
NSString *ElseLabel = [NSString stringWithFormat:@"teacher"];
self.OutputLabel.text = ElseLabel;
}
}
Elselabel
位于MainStoryboard中的另一个ViewControler中....当我通过模态segue去那里时,它不显示任何东西!感谢所有回复!

完成以下步骤
转到Appdelegate.h并添加一个像这样的NSString
@property(nonatomic,retain)NSString * lableString;
转到Appdelete.m并合成字符串
@synthesize lableString;
然后改变你的功能//不要忘记#import" AppDelegate.h"
-(IBAction)ButtonTouched:(id)sender
{
[self.InputField resignFirstResponder];
if (NSOrderedSame == [self.InputField.text caseInsensitiveCompare:@"teacher"])
{
_Correct.hidden = FALSE;
_Hider.hidden = TRUE;
_FalseHider.hidden = FALSE;
_SHOWCORRECT.hidden = TRUE;
_CorrectAnswer.hidden = TRUE;
} else {
_FalseHider.hidden = TRUE;
_Correct.hidden = TRUE;
_SHOWCORRECT.hidden = FALSE;
_CorrectAnswer.hidden = TRUE;
AppDelegate *appDelegate = [[UIApplication sharedApplication] delegate];
appDelegate.lableString = [NSString stringWithFormat:@"teacher"];
}
}
并在您的不同视图中使用此
AppDelegate *appDelegate = [[UIApplication sharedApplication] delegate];
self.OutputLabel.text = appDelegate.lableString;
不是: - 这不是最佳方法,但它肯定会给你一个小课程
