- (id )downloadImageWithURL:(NSURL *)url
options:(SDWebImageOptions)options
progress:(SDWebImageDownloaderProgressBlock)progressBlock
completed:(SDWebImageCompletionWithFinishedBlock)completedBlock;
SDWebImageDownloader--下载图片
- (id )downloadImageWithURL:(NSURL *)url
options:(SDWebImageDownloaderOptions)options
progress:(SDWebImageDownloaderProgressBlock)progressBlock
completed:(SDWebImageDownloaderCompletedBlock)completedBlock;
2、缓存管理
缓存管理--磁盘缓存
缓存管理--内存缓存
SDImageCache
AutoPurgeCache
3、UIView的便利方法集成---
UIButton+ WebCache、
UIImageView+WebCache、
UIView+ WebCache、
UIImageView+ HighlightedWebCache
4、图片解码？？？？
图片的像素分辨率神马意思， 1倍、2倍、3倍
屏幕物理像素 -- 渲染像素 缩放比率？？
UIImage-》
CGImageRef-》
创建CGContextRef上下文，
CGContextRef __nullable CGBitmapContextCreate(
void * __nullable data, //填NULL
size_t width, // size_t CGImageGetWidth(CGImageRef cg_nullable image)
size_t height, //size_t CGImageGetHeight(CGImageRef cg_nullable image)
size_t bitsPerComponent, // 8
size_t bytesPerRow, // bytesPerPixel(4) * width
CGColorSpaceRef cg_nullable space, //
CGColorSpaceRef __nullable CGImageGetColorSpace(CGImageRef cg_nullable image)
CGColorSpaceModel CGColorSpaceGetModel(CGColorSpaceRef cg_nullable space)
CGColorSpaceRef cg_nullable CGColorSpaceCreateDeviceRGB(void)
uint32_t bitmapInfo //kCGBitmapByteOrderDefault|kCGImageAlphaNoneSkipLast
)
从新绘制CGImageRef
void CGContextDrawImage(CGContextRef cg_nullable c, CGRect rect,
CGImageRef cg_nullable image)
-》再次转化为UIImage
- (instancetype)initWithCGImage:(CGImageRef)cgImage scale:(CGFloat)scale orientation:(UIImageOrientation)orientation
+ (UIImage *)imageWithCGImage:(CGImageRef)cgImage scale:(CGFloat)scale orientation:(UIImageOrientation)orientation
#import
ImageIO读取图片
从NSData转化读取到图片
CGImageSourceRef __nullable CGImageSourceCreateWithData(CFDataRef __nonnull data, CFDictionaryRef __nullable options)
从URL读取图片
CGImageSourceRef __nullable CGImageSourceCreateWithURL(CFURLRef __nonnull url, CFDictionaryRef __nullable options)
直接从UIImage转化CGImageRef
CGImageRef imageRef = image.CGImage;
CGImageSourceRef、CGImageRef什么区别？？
1、ImageIO框架---CGImageSourceRef
typedef struct IIO_BRIDGED_TYPE(id) CGImageSource * CGImageSourceRef;
2、CoreGraphics框架--CGImageRef
typedef struct CF_BRIDGED_TYPE(id) CGImage *CGImageRef;
读取图片的alpha通道
CGImageAlphaInfo CGImageGetAlphaInfo(CGImageRef cg_nullable image)
3、UIKit框架--UIImage
4、Foundation框架----NSData
5、CoreImage框架 --- CIImage
图片的张数
size_t CGImageSourceGetCount(CGImageSourceRef __nonnull isrc)
拆分的方式创建新的图片
CGImageRef __nullable CGImageSourceCreateImageAtIndex(CGImageSourceRef __nonnull isrc, size_t index, CFDictionaryRef __nullable options)
获取某一张图片的属性
CFDictionaryRef __nullable CGImageSourceCopyPropertiesAtIndex(CGImageSourceRef __nonnull isrc, size_t index, CFDictionaryRef __nullable options)
CFDictionaryRef 直接转化为NSDictionary
NSDictionary *frameProperties = (__bridge NSDictionary *)
获取图片属性字典
NSDictionary *frameProperties = (__bridge NSDictionary *)cfFrameProperties;
NSDictionary *gifProperties = frameProperties[(NSString *)kCGImagePropertyGIFDictionary];
NSNumber *delayTimeUnclampedProp = gifProperties[(NSString *)kCGImagePropertyGIFUnclampedDelayTime];
获取图片属性字典
NSDictionary *exif = [(__bridge NSDictionary *)props objectForKey : (NSString *)kCGImagePropertyExifDictionary];
NSString *model = [[[exif objectForKey:(NSString *)kCGImagePropertyExifLensModel] componentsSeparatedByString:@"camera"] firstObject];
"{GIF}" = {
DelayTime = "0.1";
UnclampedDelayTime = "0.02";
};
默认一帧时间为0.1秒； 0.1*张数。 就是整个gif图片的播放时间长度。
+ (nullable UIImage *)animatedImageWithImages:(NSArray *)images duration:(NSTimeInterval)duration
////////////////////////
创建上下文环境：
void UIGraphicsBeginImageContextWithOptions(CGSize size, BOOL opaque, CGFloat scale)
把UIImage图片绘画到图形上下文， drawInRect能大能小，有什么性能上的梗？
- (void)drawInRect:(CGRect)rect;
从图形上下文内存读取图片
UIImage* __nullable UIGraphicsGetImageFromCurrentImageContext(void)
////////////////////////
创建上下文环境：
CGContextRef __nullable CGBitmapContextCreate(void * __nullable data,
size_t width, size_t height, size_t bitsPerComponent, size_t bytesPerRow,
CGColorSpaceRef cg_nullable space, uint32_t bitmapInfo)
把CGImageRef图片绘画到图形上下文---
void CGContextDrawImage(CGContextRef cg_nullable c, CGRect rect,
CGImageRef cg_nullable image)
从图形上下文内存读取图片
CGImageRef __nullable CGBitmapContextCreateImage(
CGContextRef cg_nullable context)
CGImageRef-》转化到UIImage
+ (UIImage *)imageWithCGImage:(CGImageRef)cgImage scale:(CGFloat)scale orientation:(UIImageOrientation)orientation
问题：
两种方式解码图片， 什么区别？
1、 UIImage-》CGImageRef-》CGContextRef-》CGImageRef-》UIImage
- (nullable CGImageRef)CGImage
CGContextRef __nullable CGBitmapContextCreate(void * __nullable data,
size_t width, size_t height, size_t bitsPerComponent, size_t bytesPerRow,
CGColorSpaceRef cg_nullable space, uint32_t bitmapInfo)
void CGContextDrawImage(CGContextRef cg_nullable c, CGRect rect,
CGImageRef cg_nullable image)
CGImageRef __nullable CGBitmapContextCreateImage(
CGContextRef cg_nullable context)
+ (UIImage *)imageWithCGImage:(CGImageRef)cgImage scale:(CGFloat)scale orientation:(UIImageOrientation)orientation
2、
UIImage-》drawInRect-》UIImage
void UIGraphicsBeginImageContextWithOptions(CGSize size, BOOL opaque, CGFloat scale)
- (void)drawInRect:(CGRect)rect;
UIImage* __nullable UIGraphicsGetImageFromCurrentImageContext(void);
5、多线程
SDWebImageDownloaderOperation
#ifndef dispatch_main_async_safe
#define dispatch_main_async_safe(block)\
if (strcmp(dispatch_queue_get_label(DISPATCH_CURRENT_QUEUE_LABEL), dispatch_queue_get_label(dispatch_get_main_queue())) == 0) {\
block();\
} else {\
dispatch_async(dispatch_get_main_queue(), block);\
}
#endif
如果在main线程再dispatch_async main线程会怎么样？
dispatch_async(dispatch_get_main_queue(), ^{
NSLog(@"1111");
dispatch_async(dispatch_get_main_queue(), ^{
NSLog(@"2222");
});
});
好像也没怎么样
