自定義按鈕

Answer 2

我可以告訴你如何添加自定義按鈕，導航欄。如果這是有幫助的，請使用此代碼，

UIImage *buttonImage = [UIImage imageNamed:@"Done.png"]; 

    UIButton *aButton = [UIButton buttonWithType:UIButtonTypeRoundedRect]; 

    [aButton setImage:buttonImage forState:UIControlStateNormal]; 

    aButton.frame = CGRectMake(0.0, 0.0, buttonImage.size.width, buttonImage.size.height); 

    UIBarButtonItem *aBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:aButton]; 

    [aButtonaddTarget:selfaction:@selector(navigatehome)forControlEvents:UIControlEventTouchUpInside]; 

    self.navigationItem.rightBarButtonItem = aBarButtonItem; 

    [aBarButtonItem release];
