问题描述
我有大约300张图片要加载动画,图片名为 loading001.png,loading002.png,loading003.png,loading004.png ......... loading300.png
I have around 300 images to be loaded for animation the images are named loading001.png, loading002.png, loading003.png, loading004.png………loading300.png
我是按照以下方式进行的。
I am doing it in the following way.
.h文件
#import <UIKit/UIKit.h>
@interface CenterViewController : UIViewController {
UIImageView *imgView;
}
@end
.m文件
@implementation CenterViewController
- (void)viewDidLoad {
[super viewDidLoad];
imgView = [[UIImageView alloc] init];
imgView.animationImages = [[NSArray alloc] initWithObjects:
[UIImage imageNamed:@"loading001.png"],
[UIImage imageNamed:@"loading002.png"],
[UIImage imageNamed:@"loading003.png"],
[UIImage imageNamed:@"loading004.png"],
nil];
}
- (IBAction)startAnimation:(id)sender{
[imgView startAnimating];
}
@end
有没有一种有效的方法将图像加载到数组中。
我用 for loop
尝试了它但是无法弄明白。
Is there a efficient way to load the images into a array.
I had tried it with for loop
but was not able to figure it out.
推荐答案
您可以尝试使用以下代码以更好的方式将图像加载到数组中
You may try out the following code to load images into an array in a better way
- (void)viewDidLoad {
[super viewDidLoad];
NSMutableArray *imgListArray = [NSMutableArray array];
for (int i=1; i <= 300; i++) {
NSString *strImgeName = [NSString stringWithFormat:@"loading%03d.png", i];
UIImage *image = [UIImage imageNamed:strImgeName];
if (!image) {
NSLog(@"Could not load image named: %@", strImgeName);
}
else {
[imgListArray addObject:image];
}
}
imgView = [[UIImageView alloc] init];
[imgView setAnimationImages:imgListArray];
}
