ios 360度旋转效果demo

demo功能：用UIimageView实现360度旋转效果。

demo说明：iPhone6.1 测试成功。主要代码在：FVImageSequence.m中。在touchesMoved事件中，通过替换UIimageView的image来产生旋转效果。

demo主要代码：

-(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {[super touchesMoved:touches withEvent:event];    UITouch *touch = [[event allTouches] anyObject];    CGPoint touchLocation = [touch locationInView:self];int location = touchLocation.x;//根据移动偏移量，判断旋转的方向。if(location < previous)current += increment;elsecurrent -= increment;previous = location;//图片临界点限制，在demo中的image文件夹下有所有图片，是从不同角度拍摄的，将这些图片依次显示就可以实现360的旋转效果if(current > numberOfImages)current = 0;if(current < 0)current = numberOfImages;NSString *path = [NSString stringWithFormat:@"%@%d", prefix, current];NSLog(@"%@", path);path = [[NSBundle mainBundle] pathForResource:path ofType:extension];UIImage *img =  [[UIImage alloc] initWithContentsOfFile:path];//设置UIimageView的image为新的image，实现360度旋转效果[self setImage:img];[img release];}
