IOS 7按鈕圖像顏色

我的UIButton的一部分是UIImage，IOS 7將其顏色從黑色更改爲藍色。我嘗試了這裏提供的解決方案：將按鈕類型更改爲UIButtonTypeSystem，但這並沒有幫助，圖像仍然是藍色。這裏是我使用的通用代碼：IOS 7按鈕圖像顏色

UIButton *iWantPlan = [UIButton buttonWithType:UIButtonTypeSystem]; 
iWantPlan.frame = CGRectMake(self.view.bounds.size.width/2-bgImageWidth/2, planBg.frame.origin.y + planBg.frame.size.height + 20, bgImageWidth, bgImageWidth/4+5); 
iWantPlan.titleLabel.font = [UIFont systemFontOfSize:20]; 
[iWantPlan addTarget:self action:@selector(goToPersonalDetails) forControlEvents:UIControlEventTouchDown]; 
[self.view addSubview:iWantPlan]; 

iWantPlan.contentHorizontalAlignment = UIControlContentHorizontalAlignmentRight; 
iWantPlan.imageView.frame = CGRectMake(bgImageWidth - 20, 10, 25, 25); 
UIImage *viImage = [UIImage imageNamed:@"Icon_V.png"]; 
UIImage *viImageTap = [UIImage imageNamed:@"Icon_V_Tap.png"]; 
[iWantPlan setImage:viImage forState:UIControlStateNormal]; 
[iWantPlan setImage:viImageTap forState:UIControlStateSelected];

有沒有解決方案？（和公正順便說一句，這是很無奈:)

有了：imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal確保你沒有藍色的背景：

UIImage *viImage = [[UIImage imageNamed:@"Icon_V.png"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]; 
UIImage *viImageTap = [[UIImage imageNamed:@"Icon_V_Tap.png"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];

從Apple Documentation UIImageRenderingMode：
總是吸引原始圖像，而無需治療它作爲一個模板：UIImageRenderingModeAlwaysOriginal

此外，它可以幫助你：

UIButton *iWantPlan = [UIButton buttonWithType:UIButtonTypeCustom]; 
... 
[iWantPlan setImage:viImageTap forState:UIControlStateHighlighted];

只需將您的按鈕類型UIButtonTypeSystem更改爲UIButtonTypeCustom
