UIButton文字和图片偏移

UIButton 设置偏移

@propery　　titleEdgeInsets

@propery　　imageEdgeInsets

@propery　　contentEdgeInsets

@propery　　contentHorizontalAlignment

初始化Button

　　 UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
    NSString *title = @"音乐";
    UIImage  *image = [UIImage imageNamed:@"sp_music_list_sc"];
    [button setTitle:title forState:UIControlStateNormal];
    [button setImage:image forState:UIControlStateNormal];
    button.frame = CGRectMake(20, 100, 100, 40);
    button.backgroundColor = [UIColor grayColor];

设置文字偏移

　　CGSize titleSize = [title sizeWithFont:[UIFont systemFontOfSize:10.f]];
    CGSize imageSize = image.size;   
3     button.titleEdgeInsets = UIEdgeInsetsMake(15, -imageSize.width, 0, 0);

设置图片偏移

button.imageEdgeInsets = UIEdgeInsetsMake(-15,titleSize.width+10,0,0);

设置整体偏移 （文字和图片都会偏移）

button.contentEdgeInsets = UIEdgeInsetsMake(20, 0, 0, 0);

设置对齐方式 （UIButton）

//对齐方式  设置content是title和image一起变化
    button.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;
