给定.plist
类似于:
<plist version="1.0">
<array>
<dict>
<key>name</key>
<string>Afghanistan</string>
<key>government</key>
<string>Islamic Republic</string>
<key>population</key>
<integer>0</integer>
<key>image</key>
<string>/Flags/afghanistan.png</string>
</dict>
<dict>
<key>name</key>
<string>Albania</string>
<key>government</key>
<string>Emerging Democracy</string>
<key>population</key>
<integer>0</integer>
<key>image</key>
<string>/Flags/albania.png</string>
</dict>
.... etc.
ViewController.m :
#import "FirstViewController.h"
@implementation FirstViewController
@synthesize sortedCountries;
-(void)viewDidLoad {
NSString *path = [[NSBundle mainBundle] pathForResource:@"countries" ofType:@"plist"];
NSArray *countries = [NSArray arrayWithContentsOfFile:path];
NSSortDescriptor *descriptor = [[[NSSortDescriptor alloc] initWithKey:@"name" ascending:YES] autorelease];
self.sortedCountries = [countries sortedArrayUsingDescriptors:[NSArray arrayWithObject:descriptor]];
}
-(UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSDictionary *country = [sortedCountries objectAtIndex:indexPath.row];
NSString *countryName = [country objectForKey:@"name"];
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell =
[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:CellIdentifier] autorelease];
}
NSDictionary *item = (NSDictionary *)[sortedCountries objectAtIndex:indexPath.row];
NSString *path = [[NSBundle mainBundle] pathForResource:[item objectForKey:@"image"] ofType:@"png"];
UIImage *theImage = [UIImage imageWithContentsOfFile:path];
cell.imageView.image = theImage;
cell.textLabel.text = countryName;
return cell;
}
这使得countryName
按照UITableView单元格中的字母顺序递增。不起作用的是cell.imageView.image
。
它将afghanistan.png置于第一个UITableViewCell中。接下来的细胞也会收到afghanistan.png。 (第二个单元格应该接收'albania.png'等)。我该如何解决这个UIImageView问题?
答案 0 :(得分:2)
改为使用imageNamed
。
cell.imageView.image = [UIImage imageNamed:[item objectForKey:@"image"]];
答案 1 :(得分:1)
你应该使用
[item objectForKey:@"image"]
代替
[item objectForKey:@"imageKey"]
(因为.plist使用<key>image</key>
)。
