Ios7 iOS 7中的UISegmentedControl
我有一个有两个分段控件的项目。他们都达到了7.0。现在一个人没有了。我读过关于色彩的问题,但我认为这是不同的 两个控件都将UIImage用作段。一方面,所有图像都显示正确。另一方面,我得到了所有的蓝色图像 我是做错了什么还是这是一个错误 以下是故障段的代码:Ios7 iOS 7中的UISegmentedControl,ios7,uisegmentedcontrol,Ios7,Uisegmentedcontrol,我有一个有两个分段控件的项目。他们都达到了7.0。现在一个人没有了。我读过关于色彩的问题,但我认为这是不同的 两个控件都将UIImage用作段。一方面,所有图像都显示正确。另一方面,我得到了所有的蓝色图像 我是做错了什么还是这是一个错误 以下是故障段的代码: UISegmentedControl *colorControl = [[UISegmentedControl alloc] initWithItems: [NSArray arrayWithObjects: [UIImag
UISegmentedControl *colorControl = [[UISegmentedControl alloc] initWithItems:
[NSArray arrayWithObjects:
[UIImage imageNamed:@"White.png"],
[UIImage imageNamed:@"Red.png"],
[UIImage imageNamed:@"Yellow.png"],
[UIImage imageNamed:@"Green.png"],
[UIImage imageNamed:@"Blue.png"],
[UIImage imageNamed:@"Purple.png"],
[UIImage imageNamed:@"Black.png"], nil]];
CGRect frame = CGRectMake(rect.origin.x + kLeftMargin, rect.size.height - kPaletteHeight - kTopMargin, rect.size.width - (kLeftMargin + kRightMargin), kPaletteHeight );
colorControl.frame = frame;
// Add DoubleTap Color capability
gesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(showMoreColors:)];
[gesture setNumberOfTapsRequired:2];
[colorControl addGestureRecognizer:gesture];
// When the user chooses a color, the method changeColor: is called.
[colorControl addTarget:self action:@selector(changeColor:) forControlEvents:UIControlEventValueChanged];
// Make sure the color of the color complements the black background
//colorControl.tintColor = [UIColor clearColor];
// Add the control to the window
[self.view addSubview:colorControl];
虽然图像都是蓝色的,但片段工作正常。多亏了,我制定了以下修复方案:
-(void) buildColorBar {
//NSLog(@"%s", __FUNCTION__);
UIImage *whiteImage = [UIImage imageNamed:@"White.png"];
UIImage *blackImage = [UIImage imageNamed:@"Black.png"];
UIImage *purpleImage = [UIImage imageNamed:@"Purple.png"];
UIImage *redImage = [UIImage imageNamed:@"Red.png"];
UIImage *blueImage = [UIImage imageNamed:@"Blue.png"];
UIImage *greenImage = [UIImage imageNamed:@"Green.png"];
UIImage *yellowImage = [UIImage imageNamed:@"Yellow.png"];
NSArray *colorArray = [[NSArray alloc] initWithObjects:
[whiteImage imageWithRenderingMode: UIImageRenderingModeAlwaysOriginal],
[redImage imageWithRenderingMode: UIImageRenderingModeAlwaysOriginal ],
[yellowImage imageWithRenderingMode: UIImageRenderingModeAlwaysOriginal ],
[greenImage imageWithRenderingMode: UIImageRenderingModeAlwaysOriginal ],
[blueImage imageWithRenderingMode: UIImageRenderingModeAlwaysOriginal ],
[purpleImage imageWithRenderingMode: UIImageRenderingModeAlwaysOriginal ],
[blackImage imageWithRenderingMode: UIImageRenderingModeAlwaysOriginal ], nil ];
UISegmentedControl *colorControl = [[UISegmentedControl alloc] initWithItems:colorArray];
CGRect frame = CGRectMake(rect.origin.x + kLeftMargin, rect.size.height - kPaletteHeight - kTopMargin, rect.size.width - (kLeftMargin + kRightMargin), kPaletteHeight );
colorControl.frame = frame;
我希望它能帮助别人
