Question

我正在AppDelegate中创建一个数组，然后想在另一个视图控制器中使用它（连续重复直到我关闭视图）。它填充数组，但似乎没有动画。我已经搜索并进行了几天的编辑。任何帮助，将不胜感激！

AppDelegate.h

#import <UIKit/UIKit.h>
#import <Foundation/Foundation.h>

@interface AppDelegate : UIResponder <UIApplicationDelegate>

@property (strong, nonatomic) UIWindow *window;
@property (nonatomic, retain) NSMutableArray *sharedArray1;
@end

AppDelegate.m

#import "Scene1.h"
@synthesize sharedArray1;

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions  {

int ii;

for (ii = 1; ii<70;)   {     
    [sharedArray1 addObject:[UIImage imageWithData:[NSData dataWithContentsOfFile:[[NSBundle mainBundle]pathForResource:[NSString stringWithFormat:@"RadarCircle_Active%i.png", ii] ofType:nil]]]];
    NSLog(@"Log RadarCircle_Active i: %i",ii);
    ii = ii + 1;  // increment by 1
}

return YES;
}

Scene1.m

#import "AppDelegate.h"

-(void)radarActive{

float duration1 = 5.5;

AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
activeRadarImage.animationImages = appDelegate.sharedArray1;
activeRadarImage.animationDuration = duration1;
//    activeClawImage.animationRepeatCount = count;
[activeRadarImage startAnimating];  
}

Answer 1

在我看来，您需要在开始向其添加对象之前将sharedArray1设置为某些内容。

在开始循环之前尝试添加它：

self.sharedArray1 = [[NSMutableArray alloc] init];

Answer 2

正如@architectpianist所说，你需要先分配并尝试更改

[sharedArray1 addObject:[UIImage imageWithData:[NSData dataWithContentsOfFile:[[NSBundle mainBundle]pathForResource:[NSString stringWithFormat:@"RadarCircle_Active%i.png", ii] ofType:nil]]]];

到

[sharedArray1 addObject:[UIImage imageWithData:[NSData dataWithContentsOfFile:[[NSBundle mainBundle]pathForResource:[NSString stringWithFormat:@"RadarCircle_Active%i", ii] ofType:@"png"]]]];

或者你可以这样做

NSString *imageName = [NSString stringWithFormat:@"RadarCircle_Active%i.png", ii];
UIImage *image = [UIImage imageNamed:imageName];
NSLog(@"image : %@", image);
[sharedArray1 addObject:image];

查看NSLog。

希望它有所帮助。
