我不会录gif图,录的mp4不能上传,所以只能发截图了😂
首先需要写一个UIImage+Gif
的分类,我是直接更改了sd_webImage
的代码,可以直接更改,也可以自己按照同样代码写一个.
#import "SDWebImageCompat.h"
@interface UIImage (GIF)
- (BOOL)isGIF;
+ (UIImage *)sd_animatedGIFNamed:(NSString *)name;
@end
@implementation UIImage (GIF)
+ (UIImage *)sd_animatedGIFNamed:(NSString *)name {
CGFloat scale = [UIScreen mainScreen].scale;
if (scale > 1.0f) {
NSString *retinaPath = [[NSBundle mainBundle] pathForResource:[name stringByAppendingString:@"@2x"] ofType:@"gif"];
NSData *data = [NSData dataWithContentsOfFile:retinaPath];
if (data) {
return [UIImage sd_animatedGIFWithData:data];
}
NSString *path = [[NSBundle mainBundle] pathForResource:name ofType:@"gif"];
data = [NSData dataWithContentsOfFile:path];
if (data) {
return [UIImage sd_animatedGIFWithData:data];
}
return [UIImage imageNamed:name];
}
else {
NSString *path = [[NSBundle mainBundle] pathForResource:name ofType:@"gif"];
NSData *data = [NSData dataWithContentsOfFile:path];
if (data) {
return [UIImage sd_animatedGIFWithData:data];
}
return [UIImage imageNamed:name];
}
}
- (BOOL)isGIF {
return (self.images != nil);
}
+ (UIImage *)sd_animatedGIFWithData:(NSData *)data {
if (!data) {
return nil;
}
CGImageSourceRef source = CGImageSourceCreateWithData((__bridge CFDataRef)data, NULL);
size_t count = CGImageSourceGetCount(source);
UIImage *animatedImage;
if (count <= 1) {
animatedImage = [[UIImage alloc] initWithData:data];
}
else {
NSMutableArray *images = [NSMutableArray array];
NSTimeInterval duration = 0.0f;
for (size_t i = 0; i < count; i++) {
CGImageRef image = CGImageSourceCreateImageAtIndex(source, i, NULL);
duration += [self sd_frameDurationAtIndex:i source:source];
[images addObject:[UIImage imageWithCGImage:image scale:[UIScreen mainScreen].scale orientation:UIImageOrientationUp]];
CGImageRelease(image);
}
if (!duration) {
duration = (1.0f / 10.0f) * count;
}
animatedImage = [UIImage animatedImageWithImages:images duration:duration];
}
CFRelease(source);
return animatedImage;
}
+ (float)sd_frameDurationAtIndex:(NSUInteger)index source:(CGImageSourceRef)source {
float frameDuration = 0.1f;
CFDictionaryRef cfFrameProperties = CGImageSourceCopyPropertiesAtIndex(source, index, nil);
NSDictionary *frameProperties = (__bridge NSDictionary *)cfFrameProperties;
NSDictionary *gifProperties = frameProperties[(NSString *)kCGImagePropertyGIFDictionary];
NSNumber *delayTimeUnclampedProp = gifProperties[(NSString *)kCGImagePropertyGIFUnclampedDelayTime];
if (delayTimeUnclampedProp) {
frameDuration = [delayTimeUnclampedProp floatValue];
}
else {
NSNumber *delayTimeProp = gifProperties[(NSString *)kCGImagePropertyGIFDelayTime];
if (delayTimeProp) {
frameDuration = [delayTimeProp floatValue];
}
}
// Many annoying ads specify a 0 duration to make an image flash as quickly as possible.
// We follow Firefox's behavior and use a duration of 100 ms for any frames that specify
// a duration of <= 10 ms. See <rdar://problem/7689300> and <http://webkit.org/b/36082>
// for more information.
if (frameDuration < 0.011f) {
frameDuration = 0.100f;
}
CFRelease(cfFrameProperties);
return frameDuration;
}
SVProgressHUD.m
这里的SVProgressView
我亦是更改了源代码,因为我所有的显示都是用同一个Gif加载的.此处修改了SVProgressHUD.m
的- (void)showImage:(UIImage*)image status:(NSString*)status duration:(NSTimeInterval)duration
的方法
- (void)showImage:(UIImage*)image status:(NSString*)status duration:(NSTimeInterval)duration {
__weak SVProgressHUD *weakSelf = self;
[[NSOperationQueue mainQueue] addOperationWithBlock:^{
__strong SVProgressHUD *strongSelf = weakSelf;
if(strongSelf){
// Update / Check view hierarchy to ensure the HUD is visible
[strongSelf updateViewHierarchy];
// Reset progress and cancel any running animation
strongSelf.progress = SVProgressHUDUndefinedProgress;
[strongSelf cancelRingLayerAnimation];
[strongSelf cancelIndefiniteAnimatedViewAnimation];
// Update imageView
UIColor *tintColor = strongSelf.foregroundColorForStyle;
UIImage *tintedImage = image;
if (image.renderingMode != UIImageRenderingModeAlwaysTemplate) {
tintedImage = [image imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate];
}
strongSelf.imageView.tintColor = tintColor;
strongSelf.imageView.image = tintedImage;
strongSelf.imageView.hidden = NO;
///////////此处为修改代码///////
// 设置gif视图的大小
CGRect imageFrame = strongSelf.imageView.frame;
imageFrame.size = CGSizeMake(60, 60);
strongSelf.imageView.frame = imageFrame;
// Update text
strongSelf.statusLabel.text = status;
// Show
[strongSelf showStatus:status];
// 此处屏蔽是因为这个的加载时间是根据字符串的长度,关闭之后消失直接调用[SVProgressHUD dismiss];
// An image will dismissed automatically. Therefore we start a timer
// which then will call dismiss after the predefined duration
// strongSelf.fadeOutTimer = [NSTimer timerWithTimeInterval:duration target:strongSelf selector:@selector(dismiss) userInfo:nil repeats:NO];
// [[NSRunLoop mainRunLoop] addTimer:strongSelf.fadeOutTimer forMode:NSRunLoopCommonModes];
}
}];
}
ViewController
调用:
// 显示
[SVProgressHUD setInfoImage:[UIImage sd_animatedGIFNamed:@"source"]];
[SVProgressHUD showInfoWithStatus:@"加载中..."];
// 消失
// [SVProgressHUD dismiss];
