iOS 按钮图片和文字位置的各种设置

按钮设置title和image默认格式就是图片在左文字向右  开发中往往不尽人意

[but setTitle:[_dateForm stringFromDate:[NSDate date]] forState:UIControlStateNormal];

[but setImage:[UIImage imageNamed:@"xiala"] forState:UIControlStateNormal];

---

可以通过重写UIButton的LayoutSubViews来改成我们希望看到的布局

---

创建继承UIButton子类

.h文件如下

#importtypedef NS_ENUM(NSInteger, UIMyDefindButtonImageType) {

UIMyDefindButtonImageTypeNormal = 0,//系统默认类型 左图片 右文字

UIMyDefindButtonImageTypeTop,//上图片 下文字

UIMyDefindButtonImageTypeRight,//右图片 左文字

UIMyDefindButtonImageTypeBottom//下图片 上文字

};

@interface MyDefindButton : UIButton

@property (nonatomic,assign) UIMyDefindButtonImageType myDefindType;

@end

---

.m文件如下

#import "MyDefindButton.h"

#define Jianju 2 //图片和文字之间的间距

@implementation MyDefindButton

- (void)layoutSubviews{

[super layoutSubviews];

CGRect titleF = self.titleLabel.frame;

CGRect imageF = self.imageView.frame;

switch (self.myDefindType) {

case UIMyDefindButtonImageTypeNormal:

//不设置即为默认设置  当然设置文字与图片之间的间距也是没用的 ~~

break;

case UIMyDefindButtonImageTypeTop:{

CGRect newImageRect;

newImageRect.origin.x = self.width/2-(imageF.size.width/2);

newImageRect.origin.y = self.height/2 - ((imageF.size.height+Jianju+titleF.size.height)/2);

newImageRect.size.width = imageF.size.width;

newImageRect.size.height = imageF.size.height;

self.imageView.frame = newImageRect;

self.titleLabel.frame = CGRectMake(self.width/2-(titleF.size.width/2), self.imageView.bottom+Jianju, titleF.size.width, titleF.size.height);

}

break;

case UIMyDefindButtonImageTypeRight:{

titleF.origin.x = self.width/2-((titleF.size.width + imageF.size.width+Jianju)/2);

self.titleLabel.frame = titleF;

imageF.origin.x = CGRectGetMaxX(titleF) + 3;

self.imageView.frame = imageF;

}

break;

case UIMyDefindButtonImageTypeBottom:{

CGRect newTitleRect;

newTitleRect.origin.x = self.width/2-(titleF.size.width/2);

newTitleRect.origin.y = self.height/2 - ((imageF.size.height+Jianju+titleF.size.height)/2);

newTitleRect.size.width = titleF.size.width;

newTitleRect.size.height = titleF.size.height;

self.titleLabel.frame = newTitleRect;

self.imageView.frame = CGRectMake(self.width/2-(imageF.size.width/2), self.titleLabel.bottom+Jianju, imageF.size.width, imageF.size.height);

}

break;

default:

break;

}

}
