4.摇一摇功能的实现
摇一摇功能的本身实现十分简单,就是调用系统的两个方法即可.难点在于动画效果.其实这里的动画效果也不是很难.主要是计算有点复杂.可能是我在网上搜索到的素材有点不合适.导致要考虑各个控件的frame问题…
//实现摇一摇功能
- (void)motionBegan:(UIEventSubtype)motionwithEvent:(UIEvent *)event{
self.upLine.hidden = NO;
self.downLine.hidden = NO;
[UIViewanimateWithDuration:0.6animations:^{
self.upImageView.y -= 60;
self.upLine.y -= 60;
self.downImageView.y += 60;
self.downLine.y += 60;
}completion:^(BOOL finished) {
[UIViewanimateWithDuration:0.6animations:^{
self.upImageView.y += 60;
self.upLine.y += 60;
self.downImageView.y -= 60;
self.downLine.y -= 60;
}completion:^(BOOL finished) {
self.upLine.hidden = YES;
self.downLine.hidden = YES;
//弹出搜索框
[self showSearchView];
[self.searchViewperformSelector:@selector(removeFromSuperview)withObject:nilafterDelay:2.4];
}];
}];
}
//摇一摇结束后
- (void)motionEnded:(UIEventSubtype)motionwithEvent:(UIEvent *)event{
}
