嗨,我是 XCODE 的新手,正在尝试制作一个使用导航控制器的基于视图的应用程序。在我的一个观点中,我试图为不同的按钮附加相同的操作方法。我正在为 UIButtons 使用标签属性。
代码是
@interface firstview : UIViewController {
IBOutlet UIButton *button1;
IBOutlet UIButton *button2;
}
@property(nonatomic, retain) IBOutlet UIButton *button1;
@property(nonatomic, retain) IBOutlet UIButton *button2;
-(IBAction)push:(UIButton *)sender;
@end
#import "firstview.h"
#import "secondview.h"
@implementation firstview
@synthesize button1;
@synthesize button2;
-(IBAction)push:(UIButton *)sender{
button1.tag = 1;
button2.tag = 2;
if(sender.tag = button1.tag){
secondview *v2 = [[secondview alloc]initWithNibName:@"secondview" bundle:Nil];
v2.title =@"first button";
v2.l1.text = @"BUTTON1";
[self.navigationController pushViewController:v2 animated:YES];
[v2 release];
}
else if(sender.tag = button2.tag){
secondview *v2 = [[secondview alloc]initWithNibName:@"secondview" bundle:Nil];
v2.title =@"Select";
v2.l1.text = @"BUTTON2";
[self.navigationController pushViewController:v2 animated:YES];
[v2 release];
}
}
@end
我希望当按下特定按钮时,视图的标题和标签的文本都应该改变。但是无论我按下哪个按钮,实现上面的代码都会给我第一个按钮的视图。如果有人能告诉我哪里出了问题,我将不胜感激。
根据建议,我更改了等号。但是标签仍然没有显示文本。
