我想impliment基本UIAlertView
为我的应用程序(我用故事板)。 但是,当我跑我的应用程序,它进入调试屏幕在应用程序的加载屏幕停滞之后。
我的.h:
#import <UIKit/UIKit.h>
@interface MindTripAnim :UIViewController {
IBOutlet UIImageView *animation;
}
- (IBAction)showMessage:(id)sender;
@end
我.M:
#import "MindTripAnim.h"
@interface MindTripAnim ()
@end
@implementation MindTripAnim
- (void)viewDidLoad {
animation.animationImages = [NSArray arrayWithObjects:
[UIImage imageNamed:@"trips1.png"],
[UIImage imageNamed:@"trips2.png"],
[UIImage imageNamed:@"trips3.png"],
[UIImage imageNamed:@"trips4.png"],
[UIImage imageNamed:@"trips5.png"],
[UIImage imageNamed:@"trips6.png"],nil];
[animation setAnimationRepeatCount:0];
animation.animationDuration = 0.65;
[animation startAnimating];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (IBAction)showMessage:(id)sender
{
UIAlertView *message = [[UIAlertView alloc] initWithTitle:@"Hello World!" message:@"This is your first UIAlertview message." delegate:nil cancelButtonTitle:@"Close" otherButtonTitles:nil];
[message show];
}
@end
我不知道我做错了,或者为什么应用程序保持在加载屏幕停滞,请帮忙!
我发现这个在调试器
