從ViewController刪除陰影

Question

我使用下面的代碼顯示陰影。

UIBezierPath *shadowPath = [UIBezierPath bezierPathWithRect:CGRectMake(317, 0, 1, self.navigationController.view.frame.size.height)]; 
     self.navigationController.view.superview.layer.masksToBounds = NO; 
     self.navigationController.view.layer.shadowColor = [UIColor blackColor].CGColor; 
     self.navigationController.view.layer.shadowOffset = CGSizeMake(3, 0); /*Change value of X n Y as per your need of shadow to appear to like right bottom or left bottom or so on*/ 
     self.navigationController.view.layer.shadowOpacity = 0.5f; 
     self.navigationController.view.layer.shadowPath = shadowPath.CGPath; 

我想刪除這個陰影。我試過一些東西，但沒有工作？任何幫助表示讚賞。

Answer 1

嘗試通過更換balckColor到clearColor，不透明度爲0.0

self.navigationController.view.layer.shadowColor = [UIColor clearColor].CGColor; 
self.navigationController.view.layer.shadowOpacity = 0.0f; 

Answer 2

你能不能只設置不透明度爲0.0。

self.navigationController.view.layer.shadowOpacity = 0.0; 

謝謝!!
