WBShareKit是什么
WBShareKit是一个支持新浪微博，腾讯微博，豆瓣说，发推，网易微博等登陆，发布的开源库，认证方式使用的oauth。
官方地址是：WBShareKit
个人觉得WBShareKit是国内鲜有的优秀开源库之一。在微博大行其道的今天，很少有人将这么多的微博登陆封装到一块，当然不排除有这样的牛人，估计大多也都是有开源的心，没有开源的勇气。笔者很庆幸在接到程序内发微博的任务的时候遇到了WBShareKit，你不知道这样节省了我多少的时间。
WBShareKit用了挺久了，很稳定用着也很顺手，唯一觉得不大爽的地方就是用户登陆的时候，都是用的系统自带的safari实现的。这样的话，如果用户登陆不成功，会造成一定数量的用户流失。笔者当时也想过给WBShareKit加上程序内登陆的功能，无耐功力有限，觉得无从下手。当头两天这个任务再次被提上来了，竟然用了几个小时的时间给搞定了。不敢独享特整理出来，方便更多有这样需求的人。
主要改动:
WBShareKit.h 增加了一个UIWebViewDelegate,以及一个View
@interface WBShareKit : NSObject<UIWebViewDelegate>{
SEL _successSEL;
SEL _failSEL;
}
@property (nonatomic, retain) UIView *safariView;
SEL _successSEL;
SEL _failSEL;
}
@property (nonatomic, retain) UIView *safariView;
WBShareKit.m 系统方面，初始化并销毁新创建的view
+ (WBShareKit *)mainShare{
if (nil == _shareKit) {
_shareKit = [[WBShareKit alloc] init];
_shareKit.safariView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 460)];
}
return _shareKit;
}
- (void)dealloc{
[safariView release];
[super dealloc];
}
if (nil == _shareKit) {
_shareKit = [[WBShareKit alloc] init];
_shareKit.safariView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 460)];
}
return _shareKit;
}
- (void)dealloc{
[safariView release];
[super dealloc];
}
以下是大段的新添加的代码，直接添加到了WBShareKit.m文件的最下方
#pragma mark - safariView 弹出动画
#define kTransitionDuration 0.3

UIInterfaceOrientation orientation = [UIApplication sharedApplication].statusBarOrientation;

} else if (orientation == UIInterfaceOrientationLandscapeRight) {
return CGAffineTransformMakeRotation(M_PI/2);
} else if (orientation == UIInterfaceOrientationPortraitUpsideDown) {
return CGAffineTransformMakeRotation(-M_PI);
} else {
return CGAffineTransformIdentity;
}
}
- (void)bounce1AnimationStopped {

}
}
在WBShareKit.m中间做的操作就是把
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:url]];
替换为:
[self performSelector:@selector(doShowSafariWebView:)
withObject:url];
withObject:url];
然后就是添加了三个图片文件，that’s all
我是今天新下载的代码：
原始代码 修改后的代码
最后再次对WBShareKit作者的开源精神表示崇高的敬意！开源万岁！
