10：button显示设置不同字体
[_headerFansCountBtn setAttributedTitle:[self getStringWithTitle:@"粉丝" andValue:_curUser.fans_count.stringValue] forState:UIControlStateNormal];
方法（根据长度来设置其不同的样式显示）：
- (NSMutableAttributedString*)getStringWithTitle:(NSString *)title andValue:(NSString *)value{
NSMutableAttributedString *attriString = [[NSMutableAttributedString alloc] initWithString:[NSString stringWithFormat:@"%@ %@", title, value]];
[attriString addAttributes:@{NSFontAttributeName : [UIFont systemFontOfSize:15],
NSForegroundColorAttributeName : [UIColor blackColor]}
range:NSMakeRange(0, title.length)];
[attriString addAttributes:@{NSFontAttributeName : [UIFont systemFontOfSize:15],
NSForegroundColorAttributeName : [UIColor colorWithHexString:@"0x3bbd79"]}
range:NSMakeRange(title.length+1, value.length)];
return attriString;
}
11:UITableviewcell的accessoryType属性
cell.accessoryType = UITableViewCellAccessoryNone;//cell没有任何的样式 cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;//cell的右边有一个小箭头，距离右边有十几像素； cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton;//cell右边有一个蓝色的圆形button； cell.accessoryType = UITableViewCellAccessoryCheckmark;//cell右边的形状是对号；
12:layoutSubviews在以下情况下会被调用
a、init初始化不会触发layoutSubviews。 b、addSubview会触发layoutSubviews。 c、设置view的Frame会触发layoutSubviews，当然前提是frame的值设置前后发生了变化。 d、滚动一个UIScrollView会触发layoutSubviews。 e、旋转Screen会触发父UIView上的layoutSubviews事件。 f、改变一个UIView大小的时候也会触发父UIView上的layoutSubviews事件。 g、直接调用setLayoutSubviews。
13：导航栏的按键(自定义图片)
UIButton *settingBtn = [self navButtonWithImageName:@"settingBtn_Nav" action:@selector(settingBtnClicked:)];
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:settingBtn];
UIButton *addUserBtn = [self navButtonWithImageName:@"addUserBtn_Nav" action:@selector(addUserBtnClicked:)];
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:addUserBtn];
14:自定义表格行（继承UITableViewCell）
@interface TitleRImageMoreCell ()
@property (strong, nonatomic) UILabel *titleLabel;
@property (strong, nonatomic) UIImageView *userIconView;
@end
@implementation TitleRImageMoreCell
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {
// Initialization code
self.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
if (!_titleLabel) {
_titleLabel = [[UILabel alloc] initWithFrame:CGRectMake(kPaddingLeftWidth, ([TitleRImageMoreCell cellHeight] -30)/2, 100, 30)];
_titleLabel.backgroundColor = [UIColor clearColor];
_titleLabel.font = [UIFont systemFontOfSize:16];
_titleLabel.textColor = [UIColor blackColor];
[self.contentView addSubview:_titleLabel];
}
if (!_userIconView) {
_userIconView = [[UIImageView alloc] initWithFrame:CGRectMake((kScreen_Width- kTitleRImageMoreCell_HeightIcon)- kPaddingLeftWidth- 30, ([TitleRImageMoreCell cellHeight] -kTitleRImageMoreCell_HeightIcon)/2, kTitleRImageMoreCell_HeightIcon, kTitleRImageMoreCell_HeightIcon)];
[_userIconView doCircleFrame];
[self.contentView addSubview:_userIconView];
}
}
return self;
}
- (void)layoutSubviews{
[super layoutSubviews];
if (!_curUser) {
return;
}
self.titleLabel.text = @"头像";
[self.userIconView sd_setImageWithURL:[_curUser.avatar urlImageWithCodePathResizeToView:_userIconView] placeholderImage:kPlaceholderMonkeyRoundView(_userIconView)];
}
+ (CGFloat)cellHeight{
return 70.0;
}
@end
然后进行调用时（可以属性传值，并在不同的地方加载不同的行及其高度）：
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
if (indexPath.section == 0 && indexPath.row == 0) {
TitleRImageMoreCell *cell = [tableView dequeueReusableCellWithIdentifier:kCellIdentifier_TitleRImageMore forIndexPath:indexPath];
cell.curUser = _curUser;
[tableView addLineforPlainCell:cell forRowAtIndexPath:indexPath withLeftSpace:kPaddingLeftWidth];
return cell;
｝
else
{
TitleValueMoreCell *cell = [tableView dequeueReusableCellWithIdentifier:kCellIdentifier_TitleValueMore forIndexPath:indexPath];
}
return cell;
｝
15:当给按键的图标进行方向改变
[self setImage:[UIImage imageNamed:@"nav_arrow_down"] forState:UIControlStateNormal]; self.imageView.transform = CGAffineTransformRotate(self.imageView.transform, DEGREES_TO_RADIANS(180));//这这是进行180度转到，向下或向下
16:在导航栏中间增加一个带图片文字的控件
- (UIDownMenuButton *)initWithTitles:(NSArray *)titleList andDefaultIndex:(NSInteger)index andVC:(UIViewController *)viewcontroller{
self = [super init];
if (self) {
_titleList = titleList;
_curIndex = index;
_curShowing = NO;
_mySuperView = viewcontroller.view;
self.backgroundColor = [UIColor clearColor];
[self setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
[self setTitleColor:[UIColor lightGrayColor] forState:UIControlStateHighlighted];
[self.titleLabel setFont:[UIFont systemFontOfSize:kNavTitleFontSize]];
[self.titleLabel setMinimumScaleFactor:0.5];
[self addTarget:self action:@selector(changeShowing) forControlEvents:UIControlEventTouchUpInside];
[self refreshSelfUI];
}
return self;
}
- (void)refreshSelfUI{
NSString *titleStr = @"";
DownMenuTitle *menuObj = [self.titleList objectAtIndex:self.curIndex];
titleStr = menuObj.titleValue;
CGFloat titleWidth = [titleStr getWidthWithFont:self.titleLabel.font constrainedToSize:CGSizeMake(kScreen_Width, 30)];//获得文字的宽度
CGFloat btnWidth = titleWidth +kNavImageWidth;
self.frame = CGRectMake((kScreen_Width-btnWidth)/2, (44-30)/2, btnWidth, 30);
self.titleEdgeInsets = UIEdgeInsetsMake(0, -kNavImageWidth, 0, kNavImageWidth);
self.imageEdgeInsets = UIEdgeInsetsMake(0, titleWidth, 0, -titleWidth);
[self setTitle:titleStr forState:UIControlStateNormal];
[self setImage:[UIImage imageNamed:@"nav_arrow_down"] forState:UIControlStateNormal];
}
其中几个值：
#define kNavTitleFontSize 19
#define kScreen_Width [UIScreen mainScreen].bounds.size.width
#define kNavImageWidth (15.0+5.0)
然后直接赋给titleview：
UIDownMenuButton *navBtn = [[UIDownMenuButton alloc] initWithTitles:titleList andDefaultIndex:index andVC:self];
navBtn.menuIndexChanged = block;
self.navigationItem.titleView = navBtn;
注意：button都是有带文字跟图片的，只是图片都是在左边，要通过uiedgeinsetsmake对图片跟文字进行位置的改变。可以在导航栏的titleview做文章，放一些其它控件，或视图；
17:集合视图UICollectionView的简单使用
要遵循三个协议：UICollectionViewDataSource,UICollectionViewDelegate,UICollectionViewDelegateFlowLayout 设置单元格的布局 UICollectionViewFlowLayout *flowLayout = [[UICollectionViewFlowLayout alloc]init]; [flowLayout setItemSize:CGSizeMake(70, 100)];//设置cell的尺寸 [flowLayout setScrollDirection:UICollectionViewScrollDirectionVertical];//设置其布局方向 flowLayout.sectionInset = UIEdgeInsetsMake(5, 5, 5, 5);//设置其边界 //其布局很有意思，当你的cell设置大小后，一行多少个cell，由cell的宽度决定 然后设置集合视图： _collectionView = [[UICollectionView alloc]initWithFrame:CGRectMake(0, 0, 320, self.view.frame.size.height) collectionViewLayout:flowLayout]; _collectionView.dataSource = self; _collectionView.delegate = self; _collectionView.backgroundColor = [UIColor clearColor]; [_collectionView registerClass:[BMCollectionCell class] forCellWithReuseIdentifier:CELL_ID]; [self.view addSubview:_collectionView]; 注意：其它委托事件没全写出,比如numberOfSectionsInCollectionView等；
