IOS 7按钮图像颜色

我的

ui按钮

的一部分是

ui图像

，IOS 7将其颜色从黑色更改为蓝色。我尝试了这里提供的解决方案：将按钮类型更改为

uibuttonypesystem

，但这没有帮助，图像仍然是蓝色的。以下是我使用的通用代码：

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];

有解决办法吗？（顺便说一句，这确实令人沮丧：）

使用：

imageWithRenderingMode:uiimagerenderingmodealways或original

确保没有蓝色背景：

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

发件人：
始终绘制原始图像，而不将其视为模板：

UIImageRenderingModeAlwaysOriginal

此外，这可以帮助您：

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

只需将按钮的类型

uibuttonypesystem

更改为

uibuttonypecustom
