iOS小技巧3

将颜色合成图片

将颜色合成图片
+(UIImage *)imageWithColor:(UIColor *)color
{
    CGRect rect = CGRectMake(0.0f, 0.0f, 1.0f, 1.0f);
    UIGraphicsBeginImageContext(rect.size);
    CGContextRef context = UIGraphicsGetCurrentContext();
    
    CGContextSetFillColorWithColor(context, [color CGColor]);
    CGContextFillRect(context, rect);
    
    UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return image;
}

navigationController 设置title 颜色

    [self.navigationController.navigationBar setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
                                                                     [UIColor whiteColor], UITextAttributeTextColor,
                                                                     nil, UITextAttributeTextShadowColor,
                                                                     [NSValue valueWithUIOffset:UIOffsetMake(0, 0)], UITextAttributeTextShadowOffset,
                                                                     [UIFont fontWithName:@"Arial-Bold" size:0.0], UITextAttributeFont,
                                                                     nil]];

设置全局navigation barbuttonitem 

#pragma mark 设置全局navigation barbuttonitem 
-(void)setNaviBarButtonItemImage:(NSString *)imageName andX:(NSInteger)x andY:(NSInteger)y andW:(NSInteger)w andH:(NSInteger)h andTitle:(NSString *)title andSel:(SEL)sel andLOrR:(NSString *)lOr andTitleColor:(UIColor *)color{ 
    
    UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom]; 
    btn.frame =CGRectMake(x,y,w,h); 
    
    [btn setTitle:title forState:UIControlStateNormal]; 
    
    if (imageName.length==0 && title.length==0) { 
        
    } else if (imageName.length==0 && title.length!=0) { 
        [btn setBackgroundColor:[UIColor clearColor]]; 
        [btn setTitleColor:color forState:UIControlStateNormal]; 
    }else if(imageName.length!=0 && title.length==0){ 
        UIImage *image = [UIImage imageNamed:imageName]; 
        [btn setImage:image forState:UIControlStateNormal]; 
    }else if(imageName.length!=0 && title.length!=0){ 
        UIImage *image = [UIImage imageNamed:imageName]; 
        [btn setBackgroundImage:image forState:UIControlStateNormal]; 
        [btn setBackgroundColor:[UIColor clearColor]]; 
        [btn setTitleColor:color forState:UIControlStateNormal]; 
    } 
    
    
    [btn addTarget: self action:sel forControlEvents: UIControlEventTouchUpInside]; 
    UIBarButtonItem *bBtn = [[UIBarButtonItem alloc]initWithCustomView:btn]; 
    
    if ([lOr isEqualToString:@"left"]) { 
        [self.navigationItem setLeftBarButtonItem:bBtn]; 
    }else{ 
        [self.navigationItem setRightBarButtonItem:bBtn]; 
    } 
}

设置导航条标题的颜色

[navigationController.navigationBar setTitleTextAttributes:@{NSForegroundColorAttributeName : [UIColor whiteColor]}];

计算文字的Size

/**

 *  计算文字尺寸

 *  @param text    需要计算尺寸的文字

 *  @param font    文字的字体

 *  @param maxSize 文字的最大尺寸

 */

- (CGSize)sizeWithText:(NSString *)text font:(UIFont *)font maxSize:(CGSize)maxSize

{

    NSDictionary *attrs = @{NSFontAttributeName : font};

    return [text boundingRectWithSize:maxSize options:NSStringDrawingUsesLineFragmentOrigin attributes:attrs context:nil].size;

}

两种方法删除NSUserDefaults所有记录

//方法一
NSString *appDomain = [[NSBundle mainBundle] bundleIdentifier];
[[NSUserDefaults standardUserDefaults] removePersistentDomainForName:appDomain];

//方法二
- (void)resetDefaults {
    NSUserDefaults * defs = [NSUserDefaults standardUserDefaults];
    NSDictionary * dict = [defs dictionaryRepresentation];
    for (id key in dict) {
        [defs removeObjectForKey:key];
    }
    [defs synchronize];
}

设置Label行间距

设置label的行间距，计算高度
-(void)fuwenbenLabel:(UILabel *)labell FontNumber:(id)font AndLineSpacing:(float)lineSpacing
{
    //富文本设置文字行间距
    NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc]init];
    paragraphStyle.lineSpacing = lineSpacing;
    
    NSDictionary *attributes = @{ NSFontAttributeName:font, NSParagraphStyleAttributeName:paragraphStyle};
    labell.attributedText = [[NSAttributedString alloc]initWithString:labell.text attributes:attributes];
}

 //获取设置文本间距以后的高度
            CGRect huiDaSize = [cell.fabiaoHuifuContentLabel.attributedText boundingRectWithSize:CGSizeMake(276, MAXFLOAT) options:NSStringDrawingUsesLineFragmentOrigin context:nil];

一段文字设置多种字体颜色

给定range和需要设置的颜色，就可以给一段文字设置多种不同的字体颜色，使用方法如下: 
[self fuwenbenLabel:contentLabel FontNumber:[UIFont systemFontOfSize:15] AndRange:NSMakeRange(6, 1) AndColor:RGBACOLOR(34, 150, 253, 1)];
//设置不同字体颜色
-(void)fuwenbenLabel:(UILabel *)labell FontNumber:(id)font AndRange:(NSRange)range AndColor:(UIColor *)vaColor
{
    NSMutableAttributedString *str = [[NSMutableAttributedString alloc] initWithString:labell.text];
    
    //设置字号
    [str addAttribute:NSFontAttributeName value:font range:range];
    
    //设置文字颜色
    [str addAttribute:NSForegroundColorAttributeName value:vaColor range:range];
    
    labell.attributedText = str;
}

隐藏状态栏

-(void)viewWillDisappear:(BOOL)animated
{
    [super viewWillDisappear:animated];
    [[UIApplication sharedApplication] setStatusBarHidden:NO];
    
}
-(void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
    [[UIApplication sharedApplication] setStatusBarHidden:YES];
}

ScaleTableView-头部图片可伸缩的TableView

很多社交App中都有这样的设计。 列表顶部是一张大图，大图可以随着列表的下拉而放大。本Demo实现了这个功能。

在tabbar上添加小红点

在tabbar上添加类似于badgevalue功能的小红点。 
只需要知道tabbar的下标 
使用- (void)showBadgeOnItemIndex:(int)index  
和 - (void)hideBadgeOnItemIndex:(int)index进行显示和隐藏 
使用方法如下：[self.tabBarController.tabBar showBadgeOnItemIndex:0];
#import "UITabBar+badge.h"

#define TabbarItemNums 4.0    //tabbar的数量


@implementation UITabBar (badge)

- (void)showBadgeOnItemIndex:(int)index{
    
    [self removeBadgeOnItemIndex:index];

    UIView *badgeView = [[UIView alloc]init];
    
    badgeView.tag = 888 + index;
    
    badgeView.layer.cornerRadius = 5;
    
    badgeView.backgroundColor = [UIColor redColor];
    
    CGRect tabFrame = self.frame;
    
    float percentX = (index +0.6) / TabbarItemNums;
    
    CGFloat x = ceilf(percentX * tabFrame.size.width);
    
    CGFloat y = ceilf(0.1 * tabFrame.size.height);
    
    badgeView.frame = CGRectMake(x, y, 10, 10);
    
    [self addSubview:badgeView];
    
}

- (void)hideBadgeOnItemIndex:(int)index{
    
    [self removeBadgeOnItemIndex:index];
    
}

- (void)removeBadgeOnItemIndex:(int)index{
    
    for (UIView *subView in self.subviews) {
        
        if (subView.tag == 888+index) {
            
            [subView removeFromSuperview];
            
        }
    }
}

@end

获取一个类的所有子类

通过objc_copyClassList获取所有类，并通过class_getSuperclass来判断那类型继承于该类
+ (NSArray *) allSubclasses
{
    Class myClass = [self class];
    NSMutableArray *mySubclasses = [NSMutableArray array];
    
    unsigned int numOfClasses;
    Class *classes = objc_copyClassList(&numOfClasses;);
    for (unsigned int ci = 0; ci < numOfClasses; ci++) {
        Class superClass = classes[ci];
        do {
            superClass = class_getSuperclass(superClass);
        } while (superClass && superClass != myClass);
        
        if (superClass)
            [mySubclasses addObject: classes[ci]];
    }
    free(classes);
    
    return mySubclasses;
}

类似广告的文字循环滚动

-(void)viewDidLoad
{
    timer = [[NSTimer alloc] init];

      mainsco = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 0, 0)];
        mainsco.backgroundColor = [UIColor clearColor];
        [bgView addSubview:mainsco];
        //显示广告内容
        noticeLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 0, 0)];
        noticeLabel.numberOfLines = 0;
        noticeLabel.font = [UIFont systemFontOfSize:13.0f];
        noticeLabel.backgroundColor = [UIColor clearColor];
        [mainsco addSubview:noticeLabel];

  noticeLabel.text =[dic valueForKey:@"Bulletin"];

    noticeSize = [ [dic valueForKey:@"Bulletin"] sizeWithFont:[UIFont systemFontOfSize:13.0f] constrainedToSize:CGSizeMake(180, 20000000)]; 
//所有文字显示在一行所占的高度
    size1 = [[dic valueForKey:@"Bulletin"] sizeWithFont:[UIFont systemFontOfSize:13.0f]];
   mainsco.contentSize = CGSizeMake(180, noticeSize.height);
    mainsco.showsVerticalScrollIndicator = NO;
／／根据文字的多少设置label的宽高,但底层的scrollview只显示一行内容的高度
    noticeLabel.frame = CGRectMake(0, 0, 180, noticeSize.height);
    
    mainsco.frame =CGRectMake(116, 77, 180, size1.height);
    if (noticeSize.height>size1.height)
    {
    //如果文字大于一行就开始滚动，否则停止timer
          timer =  [NSTimer scheduledTimerWithTimeInterval:0.1 target:self selector:@selector(time) userInfo:self repeats:YES];
     
    }else{
        [timer invalidate];
    }
｝
//滚动的方法
-(void)time
{
    //oldy用来记录上一次scrollview滚动的位置
    mainsco.contentOffset = CGPointMake(0, oldy);
    if (oldy>noticeSize.height-1) {
        oldy = 0;
    }else
        oldy++;／／设置每次滚动的高度，即几个像素
}

分组列表头部空白处理

在viewWillAppear里面添加如下代码：
//分组列表头部空白处理
    CGRect frame = myTableView.tableHeaderView.frame;
    frame.size.height = 0.1;
    UIView *headerView = [[UIView alloc] initWithFrame:frame];
    [myTableView setTableHeaderView:headerView];

        NSString *substr = [str substringWithRange:NSMakeRange(i, 1)];
        NSString *a = [dictionary objectForKey:substr];
        NSString *b = digits[str.length -i-1];
        NSString *sum = [a stringByAppendingString:b];
        if ([a isEqualToString:chinese_numerals[9]])
        {
            if([b isEqualToString:digits[4]] || [b isEqualToString:digits[8]])
            {
                sum = b;
                if ([[sums lastObject] isEqualToString:chinese_numerals[9]])
                {
                    [sums removeLastObject];
                }
            }else
            {
                sum = chinese_numerals[9];
            }
            
            if ([[sums lastObject] isEqualToString:sum])

解决办法：打开mac系统的“实用工具”-“钥匙串访问”-“我的证书”中，会看到有证书名一模一样的，那么请将早期的证书删除掉，重启Xcode；
 
2、在真机或者模拟器编译程序的时候可能会遇到下面的错误：
Could not change executable permissions on the application.
原因：拥有相同的bundle Identifier已经在设备上运行
解决办法：删除设备中或者模拟器中的App。
 
3、编译时遇到如下错误：
A valid provisioning profile matching the application's Identifier 'XXXX' could not be found
原因：缺少证书或者是在Code Signing Identity处没有选择对应的证书或者是证书不对应
解决办法：重装证书，检查证书是否是否选择是否对应。
 
4、编译时遇到如下错误：
ld: library not found for -lmp3lameclang: error: linker command failed with exit code 1 (use -v to see invocation)
原因：一般是多人编辑同一个工程时其中一人没将某个库上传导致的
解决办法：上传具体静态库
