问题描述
我有一个UIColor + MyLayout.m文件,例如:
I have a UIColor+MyLayout.m file such as:
@implementation UIColor (Layout)
- (UIColor *) textBackground
{
UIColor *lightGreen = [UIColor colorWithRed:0.0f/255.0f green:178.0f/255.0f blue:238.0f/255.0f alpha:1.0f];
return lightGreen;
}
@end
我添加了.h文件到我的viewcontroller.m,但如何将其调用为UIColor?
I have added the .h file to my viewcontroller.m, but how do I call this into a UIColor?
UIColor * myColor =?
UIColor *myColor = ?
推荐答案
如果您执行以下操作会更好:
Would be better if you do the following:
@implementation UIColor (Layout)
+ (UIColor *) textBackground {
UIColor *lightGreen = [UIColor colorWithRed:0.0f/255.0f green:178.0f/255.0f blue:238.0f/255.0f alpha:1.0f];
return lightGreen;
}
@end
然后只需将其称为 UIColor * myColor = [UIColor textBackground];
