不知道大家有没有碰到过加载一张gif图的问题这里我整理了两个方法第一个是通过html 加载到一个Web上另一个是通过SDWebImage来实现的其实两个原理都是差不多的使用第三方可能比较简单但是大家可以可以自己写一下,话不多说上代码:

第一种方法:

[super.navigationController setNavigationBarHidden:YES animated:TRUE];

webView = [[UIWebView alloc]init];

webView.frame = CGRectMake(0, 0, self.view.bounds.size.width, self.view.bounds.size.height);

// 设定位置和大小

NSString *html = [NSString stringWithFormat:@"<html><head><style>body{margin:0px;padding:0px}</style></head><body><img border=\"0\" src = \"searchwait.gif\" width=\"%f\"height=\"%f\" style=\"position: absolute; z-index: -1;margin:0px;padding:0px\"><body></head></html>",self.view.bounds.size.width,self.view.bounds.size.height];

NSString *path = [[NSBundle mainBundle] pathForResource:@"searchwait"ofType:@"gif"];

NSURL *baseURL = [NSURL fileURLWithPath:path];

[webView loadHTMLString:html baseURL:baseURL];

webView.userInteractionEnabled = NO;

webView.backgroundColor = wc_white;

webView.contentMode = UIViewContentModeScaleAspectFill;

webView.clipsToBounds = YES;

[self.view addSubview:webView];

第二种方法:

- (void)initLoadingImageView

{

NSString *name =@"loading.gif";

NSString *filePath = [[NSBundlebundleWithPath:[[NSBundlemainBundle]bundlePath]]pathForResource:nameofType:nil];

NSData *imageData = [NSDatadataWithContentsOfFile:filePath];

if (!self.loadingImageView) {

self.loadingImageView = [[UIImageView alloc]init];

}

// imgView.image = [UIImage animatedImageWithAnimatedGIFData:imageData];

self.loadingImageView.backgroundColor = [UIColor clearColor];

self.loadingImageView.image = [UIImage sd_animatedGIFWithData:imageData];

self.loadingImageView.frame = CGRectMake(0,0,100,250/2.0);

[self.view addSubview:self.loadingImageView];

[self.view bringSubviewToFront:self.loadingImageView];

}
