Question

我正在尝试找到一种方法来检测我的应用中的按钮文字。基本上，它是一个迷你应用程序商店。我有一个蓝色安装按钮，当它被轻敲，并变成绿色并说确认。（就像iOS App Store一样。）有没有办法检测按钮何时显示文本“CONFIRM”，所以当它显示时点击它，链接会打开以安装应用程序？或者，另一种方法是检测按钮点击，但对我来说，没有任何方法可以帮助我。这是我目前的代码：

- (IBAction)buttonDownload:(id)sender {
   //in the storyboard file, the button is set to say "INSTALL"
   [sender setTitle:@"CONFIRM" forState:UIControlStateNormal];
   [sender setTitleColor:[UIColor colorWithRed:45.0f/255.0f green:152.0f/255.0f blue:0.0f/255.0f alpha:1.0] forState:UIControlStateNormal];
   [[self.appInstallOutlet layer] setBorderColor:[UIColor colorWithRed:45.0f/255.0f green:152.0f/255.0f blue:0.0f/255.0f alpha:1.0].CGColor];

//now, if the button displays "CONFIRM", open the link from a JSON file...
//Here is where the if statement should start...
    NSString *linkForApp = [self.appDetails objectForKey:@"linkForApp"];
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString: linkForApp]];
//end if statement

我使用以下代码找到了解决方案：

    UIButton *resultButton = (UIButton *)sender;
if ([resultButton.currentTitle  isEqualToString: @"INSTALL"]) {
    [sender setTitle:@"CONFIRM" forState:UIControlStateNormal];
    [sender setTitleColor:[UIColor colorWithRed:45.0f/255.0f green:152.0f/255.0f blue:0.0f/255.0f alpha:1.0] forState:UIControlStateNormal];
    [[self.appInstallOutlet layer] setBorderColor:[UIColor colorWithRed:45.0f/255.0f green:152.0f/255.0f blue:0.0f/255.0f alpha:1.0].CGColor];



}
else if ([resultButton.currentTitle isEqualToString:@"CONFIRM"]) {
NSString *linkForApp = [self.restuarantDetail objectForKey:@"linkForApp"];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString: linkForApp]];
}

检测Xcode中的按钮文本？
