UIButton上同时显示图片和文字的方法

参考：http://blog.csdn.net/qijianli/article/details/8152726

不过有个问题，就是我使用时不能改变文字的颜色，后来修改了一下方法，如下：

定义一个UIButton+Manager文件，在.h

#import <UIKit/UIKit.h>

@interface UIButton (UIButtonImageWithLable)
- (void) setImage:(UIImage *)image withTitle:(NSString *)title forState:(UIControlState)stateType;
@end

在.m中

#import "UIButton+Manager.h"

@implementation UIButton (UIButtonImageWithLable)
- (void) setImage:(UIImage *)image withTitle:(NSString *)title forState:(UIControlState)stateType {
//UIEdgeInsetsMake(CGFloat top, CGFloat left, CGFloat bottom, CGFloat right)

CGSize titleSize = [title sizeWithFont:[UIFont systemFontOfSize:12.0]];
[self.imageView setContentMode:UIViewContentModeCenter];
[self setImageEdgeInsets:UIEdgeInsetsMake(-8.0,
0.0,
0.0,
-titleSize.width)];
[self setImage:image forState:stateType];

[self.titleLabel setContentMode:UIViewContentModeCenter];
[self.titleLabel setBackgroundColor:[UIColor clearColor]];
[self.titleLabel setFont:[UIFont systemFontOfSize:12.0]];
[self setTitleColor:[UIColor blueColor] forState:stateType];//用这个方法替换下面的方法，文字的颜色就可以显示了。
//[self.titleLabel setTextColor:[UIColor blueColor]];
if (stateType == UIControlStateSelected) {
[self setTitleColor:[UIColor blueColor] forState:UIControlStateSelected];
}else{
[self setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
}

[self setTitleEdgeInsets:UIEdgeInsetsMake(35.0,
-image.size.width,
0.0,
0.0)];
[self setTitle:title forState:stateType];

}

@end

有点困惑，有兴趣的朋友可以来解惑下。我看好你汗清。
