本文介绍了一个iOS应用中市场头部视图点击事件的具体处理逻辑，通过判断用户点击的位置来触发相应的委托方法，并传递点击索引及市场信息模型。

-(void)tapGestureAction:(UITapGestureRecognizer *)tapGesture
{
    CGPoint point = [tapGesture locationInView:self];
    if (self.delegate && [self.delegate respondsToSelector:@selector(marketHeaderViewDidClickedIndex:marketInfoModel:)]) {
        JMSMarketsInfoModel *marketInfoModel = nil;
        NSInteger index = -1;
        if (CGRectContainsPoint(self.leftView.frame, point)) {
            index = 0;
            if (self.marketsInfoModels.count > 0) {
                marketInfoModel = self.marketsInfoModels[0];
            }
        }else if (CGRectContainsPoint(self.middleView.frame, point)){
            index = 1;
            if (self.marketsInfoModels.count >= index+1) {
                marketInfoModel = self.marketsInfoModels[1];
            }
        }else if(CGRectContainsPoint(self.rightView.frame, point)){
            index = 2;
            if (self.marketsInfoModels.count >= index + 1) {
                marketInfoModel = self.marketsInfoModels[2];
            }
        }
        if (index != -1) {
            [self.delegate marketHeaderViewDidClickedIndex:index marketInfoModel:marketInfoModel];
        }
    }
}
