七牛文件上傳的過程，如下圖所示
QiNiu-Progress.png
如果你不是很熟悉七牛SDK的集成過程，這里給您一點提示: cocoaPods podfile pod 'Qiniu' 引入七牛SDK文件.
過程如下：@1 獲取上傳文件到七牛的token，即用戶權(quán)限。
@2 引用七牛SDK中文件方法，上傳文件，上傳成功和失敗皆是有回調(diào)數(shù)據(jù)的。
QNUploadOption *opt = [[QNUploadOption alloc] initWithMime:nil progressHandler:progress params:nil checkCrc:NO cancellationSignal:nil];
QNUploadManager *uploadManager = [[QNUploadManager alloc]initWithRecorder:nil];
[uploadManager putData:data key:nil token:token complete:^(QNResponseInfo *info, NSString *key, NSDictionary *resp) {
if (info.statusCode == 200 && resp) {
NSString *url;
url = [NSString stringWithFormat:@"%@%@", [[NSUserDefaults standardUserDefaults] objectForKey:@"token"], resp[@"key"]];
if (success) {
success(url);
}
} else {
if (failure) {
failure();
}
}
} option:opt];
下邊給出批量上傳的方法：
該類用于接收成功和失敗的回調(diào)
#import <Foundation/Foundation.h>
@interface QiNiuUploadHelper : NSObject
/**
* 成功回調(diào)
*/
@property (copy, nonatomic) void (^singleSuccessBlock)(NSString *);
/**
* 失敗回調(diào)
*/
@property (copy, nonatomic) void (^singleFailureBlock)();
+ (instancetype)sharedInstance;
@end
.m實現(xiàn)方式
#import "QiNiuUploadHelper.h"
static QiNiuUploadHelper *_sharedInstance ;
@implementation QiNiuUploadHelper
+ (instancetype)sharedInstance {
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
_sharedInstance = [[QiNiuUploadHelper alloc] init];
});
return _sharedInstance;
}
-(id)copyWithZone:(NSZone *)zone{
return _sharedInstance;
}
+(id)allocWithZone:(struct _NSZone *)zone{
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
_sharedInstance = [super allocWithZone:zone];
});
return _sharedInstance;
}
@end
