iOS 图片view设置gif动图

这里有两张设置的方法

第一种:使用第三方框架sdwebimage

#import"UIImage+GIF.h"

NSString*name =@"750-611"; //图片的名字

NSString*filePath = [[NSBundlebundleWithPath:[[NSBundlemainBundle]bundlePath]]pathForResource:nameofType:@"gif"];

NSData*imageData = [NSDatadataWithContentsOfFile:filePath];

_dImg.backgroundColor= [UIColorclearColor];

_dImg.image= [UIImagesd_animatedGIFWithData:imageData];


第二种:引入UIImageView的子类ZLGIFImageView(自定义的类)

#import"ZLGIFImageView.h"

NSString* filePath  = [[NSBundle mainBundle] pathForResource:@"750-611" ofType:@"gif"];

NSData* imageData   = [NSData dataWithContentsOfFile:filePath];

[_dImg setData:imageData];

下边是ZLGIFImageView.h 和 ZLGIFImageView.m文件


ZLGIFImageView.h

#import@interface ZLGIFImageFrame : NSObject {

}

@property (nonatomic) double duration;

@property (nonatomic, retain) UIImage* image;

@end

@interface ZLGIFImageView : UIImageView {

NSInteger _currentImageIndex;

}

@property (nonatomic, retain) NSArray* imageFrameArray;

@property (nonatomic, retain) NSTimer* timer;

//Setting this value to pause or continue animation;

@property (nonatomic) BOOL animating;

- (void)setData:(NSData*)imageData;

- (void)closeAnim;

- (void)startAnim;

- (void)stopAnim;

@end



ZLGIFImageView.m

#import "ZLGIFImageView.h"
#import
@implementation ZLGIFImageFrame

@synthesize image = _image;

@synthesize duration = _duration;

- (void)dealloc

{

[_image release];

[super dealloc];

}

@end

@interface ZLGIFImageView ()

- (void)resetTimer;

- (void)showNextImage;

@end

@implementation ZLGIFImageView

@synthesize imageFrameArray = _imageFrameArray;

@synthesize timer = _timer;

@synthesize animating = _animating;

- (void)closeAnim

{

[self release];

}

- (void)stopAnim

{

[self resetTimer];

[_timer release];

}

- (void)startAnim

{

[self resetTimer];

_currentImageIndex = -1;

_animating = YES;

[self showNextImage];

}

- (void)dealloc

{

[self resetTimer];

[_imageFrameArray release];

[_timer release];

[super dealloc];

}

- (void)resetTimer {

if (_timer && _timer.isValid) {

[_timer invalidate];

}

self.timer = nil;

}

- (void)setData:(NSData *)imageData {

if (!imageData) {

return;

}

[self resetTimer];

CGImageSourceRef source = CGImageSourceCreateWithData((CFDataRef)imageData, NULL);

size_t count = CGImageSourceGetCount(source);

NSMutableArray* tmpArray = [NSMutableArray array];

for (size_t i = 0; i < count; i++) {

ZLGIFImageFrame* gifImage = [[[ZLGIFImageFrame alloc] init] autorelease];

CGImageRef image = CGImageSourceCreateImageAtIndex(source, i, NULL);

gifImage.image = [UIImage imageWithCGImage:image scale:[UIScreen mainScreen].scale orientation:UIImageOrientationUp];

NSDictionary* frameProperties = [(NSDictionary*)CGImageSourceCopyPropertiesAtIndex(source, i, NULL) autorelease];

gifImage.duration = [[[frameProperties objectForKey:(NSString*)kCGImagePropertyGIFDictionary] objectForKey:(NSString*)kCGImagePropertyGIFDelayTime] doubleValue];

gifImage.duration = MAX(gifImage.duration, 0.01);

[tmpArray addObject:gifImage];

CGImageRelease(image);

}

CFRelease(source);

self.imageFrameArray = nil;

if (tmpArray.count > 1) {

self.imageFrameArray = tmpArray;

_currentImageIndex = -1;

_animating = YES;

[self showNextImage];

} else {

self.image = [UIImage imageWithData:imageData];

}

}

- (void)setImage:(UIImage *)image {

[super setImage:image];

[self resetTimer];

self.imageFrameArray = nil;

_animating = NO;

}

- (void)showNextImage {

if (!_animating) {

return;

}

_currentImageIndex = (++_currentImageIndex) % _imageFrameArray.count;

ZLGIFImageFrame* gifImage = [_imageFrameArray objectAtIndex:_currentImageIndex];

[super setImage:[gifImage image]];

self.timer = [NSTimer scheduledTimerWithTimeInterval:gifImage.duration target:self selector:@selector(showNextImage) userInfo:nil repeats:NO];

}

- (void)setAnimating:(BOOL)animating {

if (_imageFrameArray.count < 2) {

_animating = animating;

return;

}

if (!_animating && animating) {

_animating = animating;

if (!_timer) {

[self showNextImage];

}

} else if (_animating && !animating) {

_animating = animating;

[self resetTimer];

}

}
